When it comes to skincare, ingredients are key to ensuring a product’s purpose and whether or not it actually yields results. And, one skincare ingredient that gets a ton of attention for both its efficacy and usage is retinol, especially over-the-counter retinol.

“Retinol is a form of vitamin A that encourages skin cell turnover, making it an effective treatment for a range of skin concerns, including acne, wrinkles, and uneven skin tone,” Dr. Julia Carroll, a board-certified dermatologist, tells PEOPLE. “Incorporating retinol into your skincare routine can improve your skin’s texture, diminish fine lines and wrinkles, and even out skin tone.” 

Popular in preventative and anti-aging skincare routines alike, retinol is a go-to for many. So how do you know what the best over-the-counter retinol actually is? You test it. After testing 32 options, we unveil the best retinol serums, creams, and treatments for smoothing fine lines, wrinkles, and much more that are worthy of that coveted spot in your skincare lineup. 

Here are the best retinol formulas that PEOPLE Tested.

Pros
  • This lightweight formula absorbs well into the skin.

  • It's gentle and safe enough for more sensitive skin types.

  • This multifunctional retinol cream also includes nourishing ingredients.

  • It improved the appearance of dark spots, fine lines, and wrinkles during our 12-week testing period.

Cons
  • Since it is cream-based, it’s not as potent as other formulas on our list (however, it is one of the most gentle).

Our top pick for the best over-the-counter retinol is the LilyAna Naturals Retinol Cream for Face, available in several sizes on Amazon. The cream-based retinol has a lightweight, soft, and supple texture that absorbs well on the skin, and since it’s not a more potent serum, it’s safe enough for more sensitive skin types. Plus, it’s formulated with ultra-nourishing ingredients like hyaluronic acid, vitamin E, shea butter, jojoba oil, and aloe, making it a fantastic option for those with dry or dehydrated skin. 

After testing this retinol face cream for 12 weeks, we saw a noticeable difference in our complexion as our dark spots appeared lighter and our fine lines and wrinkles were smoother than when we first started using the product. Our skin tone also looked more radiant, giving us a nice glow all around. Overall, we loved this retinol cream because it has a gentle formula that is safe for all skin types, is multitasking with its super-nourishing and moisturizing ingredients, and its lightweight feel doesn’t leave us feeling like we have a thick mask on despite being so hydrating.

Cons
  • The formula is gentle and designed for daily use.

  • It's fast-absorbing, so it's easy to layer with other products.

  • The formula is unscented, so those with fragrance sensitivities can still use it.

Cons
  • While it worked to improve the appearance of lines, we didn’t notice a difference in our skin’s texture.

If you’re looking for a good anti-aging serum, you don’t have to look beyond the aisles of your local drugstore, thanks to Neutrogena’s Rapid Wrinkle Repair Retinol Anti-Aging Face Serum. This potent elixir is formulated with vitamin A (a.k.a. retinol) to target the appearance of fine lines, and after regular use, we saw it do just that. In addition to smoothing out the fine lines on our complexion, we also love that this product is unscented and gentle enough for daily use, which isn’t the case with other formulas. We were also impressed by how quickly the formula absorbs into the complexion as this made layering other formulas much easier. 

While we didn’t see a difference in our skin’s texture or fading of dark spots, we loved the way the drugstore retinol targeted our fine lines and were, overall, highly impressed by the outcome — especially for the price.

Pros
  • It absorbs well, which makes it easy to layer.

  • We didn’t experience any irritation when using this product (even on sensitive skin).

  • It works wonders for evening skin tone and resurfacing texture.

Cons
  • It doesn’t work as well at smoothing fine lines and wrinkles compared to others we tested.

If dark spots are a concern, retinol can help you target the discoloration. The best retinol for dark spots is The Inkey List SuperSolutions 1% Retinol Serum, which in addition to retinol also features apricot kernel oil and squalane in its formula to provide deep nourishment while resurfacing the skin’s texture, evening out tone, and addressing dark spots as well as other blemishes.

While we didn’t think it worked as well as smoothing fine lines and wrinkles, we saw significant differences in our dark spots after every use. We were also highly impressed by how well the formula smoothed out the skin’s surface (it got rid of pesky bumps and blemishes with ease!) and how easy the application process was. On top of all of that, we found that this retinol absorbs well and wasn’t too potent for our tester's sensitive skin, which was a major perk considering its concentration and how well it performs.

Pros
  • This thick and nourishing face cream noticeably improves skin suppleness.

  • It's fast-absorbing and easy to layer with other products.

  • The fragrance-free formula is safer for sensitive skin types.

Cons
  • Since it’s a face cream, the retinol isn’t as potent as the serum products we tested.

With its thick and creamy texture, the L’Oréal Triple Power Anti-Aging Moisturizer is our top pick for the best over-the-counter retinol for dry skin. When testing out this cream, we noticed it’s fast-absorbing, and therefore, easy to layer with other products, doesn’t feel sticky, and its fragrance-free formula makes it safe for sensitive skin types.

We noticed an improvement in the suppleness of our skin after using this nourishing cream. Since it is cream-based and not a serum, the retinol isn’t as potent as the serums on our list, however, it’s still a fantastic choice for those looking for a retinol that is gentle and effective enough on dry and sensitive or easily irritated skin.

Pros
  • This formula is fragrance-free.

  • It is highly effective at fading dark spots.

  • It also boosts the complexion and supports the moisture barrier.

  • It’s non-comedogenic, so it’s safe for oily skin types.

Cons
  • It doesn’t smooth fine lines and wrinkles as well as other formulas on our list.

Retinol and sensitive skin types don’t typically go together; however, the CeraVe Resurfacing Retinol Serum shakes that up with its fragrance-free formula. Enhanced with nourishing ingredients such as niacinamide for calming the complexion, licorice root for adding radiance to the skin, and ceramides to support the skin’s moisture barrier, this drugstore retinol serum didn’t cause any irritation, even after multiple uses.

While we didn’t notice a difference in the appearance of fine lines and wrinkles, we did see a noticeable fading of dark spots as well as a boost of the skin that gave us an overall glowy complexion. In addition to being safe for sensitive skin types, the serum is also safe for oily skin, thanks to its lightweight hydration and non-comedogenic formula.

Pros
  • This formula features a potent retinoid, adapalene.

  • It's gentle enough to use morning and night.

  • It did not cause drying or skin irritation.

Cons
  • It didn’t clear red marks.

Retinoids aren’t just for wrinkles and dark spots — they can clear up acne, too. For an effective acne treatment, consider Differin Gel Acne Treatment which is formulated with adapalene, an FDA-approved retinoid for targeting acne. After testing this formula, we were most impressed by how well it got rid of most of our blemishes without drying our skin or causing any irritation. It's also gentle enough to use morning and night. While the formula didn’t clear red marks, it helped smooth out the complexion and free it from pesky bumps while also providing a thorough cleanse. 

Since this treatment is formulated specifically for acne, we didn’t notice a major difference in fine lines and wrinkles — however, it did help clarify the complexion and give us a more supple and youthful-looking glow.

  • This formula contains both retinol and bakuchiol, a potent plant-based retinol alternative.

  • It's super easy to apply and is travel-friendly.

  • This formula feels gentle and lightweight on the skin.

Cons
  • It leaves behind a slight oily sheen, which might not be ideal for all skin types.

Whether you want the convenience of a stick serum or are looking for the best retinol formula for travel, you’ll find it in the Peace Out Retinol Face Stick. Enriched with papaya enzymes, pumpkin enzymes, and both retinol and bakuchiol (a retinol alternative), this stick serum feels gentle and lightweight on the skin while working to smooth out fine lines and wrinkles and exfoliate the complexion.

In addition to its visible benefits, we love that this easy-to-apply formula is antioxidant-rich, meaning it can protect against environmental aggressors like pollution and the sun’s UV rays which cause premature signs of aging in the first place. After application, we noticed a slight oily sheen on our skin, which might not be ideal for all skin types.

  • It's gentle and doesn’t irritate the skin.

Cons
  • We found that it smells a bit off-putting, but this is subjective.

With its ability to smooth fine lines and wrinkles, retinol is an excellent ingredient to incorporate under the eyes. Our top pick for the best retinol eye cream is the Pixi Overnight Retinol Oil, which worked well at targeting dark circles and providing an overall bright-eyed look with regular use.

While the formula smells a little strange (sort of like popcorn) we didn’t mind it due to how well it worked at nourishing the thin and delicate skin around the eyes. The formula contains peptides and ceramides for added nourishment and hydration, and it's gentle and doesn't irritate sensitive skin. After using this formula for several weeks, we also noticed our skin looked firmer and the fine lines were a little more blurred out, too.

Pros
  • This product blurs the look of pores while resurfacing the complexion.

  • After regular use, our skin looks and feels more supple.

  • The exfoliating formula helps slough off dead skin cells for a softer complexion.

Cons
  • It's formulated for oily and combination skin types, so it may not be ideal for everyone (though, we loved it on our dry skin).

The cost of retinol products can range quite a bit, and if you’re looking to splurge, we highly recommend the Shani Darden Skin Care Retinol Reform Treatment Serum. In addition to retinol, this luxe serum features a formula with exfoliating apple fruit extract and AHAs to target excess oil and congestion. While it’s technically formulated for oily and combination skin types, we tried this serum on our dry skin and found that it worked well at lifting away dead skin cells and never felt like it was stripping or drying. In fact, with regular use, our skin looked and felt more supple and nourished. Plus, the focus on exfoliation helped slough off dead skin cells, left our complexion softer, and reduced the appearance of large pores.

While it is a bit of a splurge for the 1-ounce bottle, the product also comes in a smaller 0.3-ounce size, so if you want to try it without making the full investment, that is an excellent way to do so.

Pros
  • This formula promotes skin purging, which ultimately helps clear up acne breakouts.

  • It helped even out the skin tone.

  • It features ceramides and peptides to support the skin’s moisture barrier.

  • The product is free of fragrance, and we didn’t notice any skin sensitivity or irritation during the testing period.

Cons
  • Some might not like the skin-purging effect.

If you have concerns about your skin’s texture, consider giving Paula’s Choice 1% Retinol Booster a try. While testing out this retinol formula, our tester experienced some slight skin purging which, at first, didn’t help the texture concerns. However, after helping to clear up blemishes and rid our skin of breakouts, we noticed a significant difference in the texture of the skin as it was no longer bumpy and much smoother than before. Additionally, the retinol formula helped even out the skin’s tone, and as a result, our tester's complexion is now more radiant than before. 

On top of its retinol superstar ingredient, this Paula’s Choice serum also features deeply nourishing ceramides and peptides to support the skin’s moisture barrier and restore hydration. It’s also a fragrance-free formula, so it’s safer to use on sensitive skin types (though, since it is a retinol product, we recommend patch-testing first).

Pros
  • This product is quick-absorbing, so it layers well.

  • The thin texture is great for those who don’t want a thick, heavy consistency.

  • With regular use, our skin looks firmer.

Cons
  • This is a very potent formula, so you may have to ease into using it, especially if you're new to retinol.

  • It leaves a slight yellow sheen (but this doesn't last long).

If you want to address uneven skin tone, the right retinol product can surely do the trick. Our top pick for this category is the Youth To The People Retinal + Niacinamide Youth Serum. With its potent formula of retinol, niacinamide, adaptogenic mushrooms, and ceramides, this face serum is a little on the strong side, so we recommend it for those who are already used to retinol (or, if you’re brand new, we definitely recommend easing into it). However, we found that it’s highly effective at clearing and evening the skin’s tone. We were especially impressed by how well it faded old acne marks and helped keep our complexion clear and free of new blemishes, too. 

It has a thin, lightweight texture that feels comfortable. It also made our skin look firmer and didn't cause any irritation. While the lightweight serum does leave behind a slight yellow sheen, we found that this serum is fast-absorbing and not sticky so it’s super effective at layering.

Size: 1 ounce | Star Ingredients: Retinol, niacinamide, adaptogenic mushroom, ceramide complex | Benefits: Improves skin texture, balances skin tone, supports the skin’s moisture barrier, moisturizes, and improves skin sensitivity

Pros
  • The gel formula is cooling and gentle on most skin types.

  • This product features retinaldehyde, which is a more potent over-the-counter retinoid compared to retinol.

  • It works to revive skin texture for a smoother and more supple surface.

Cons
  • Since it’s formulated with a more potent retinoid, it might be too strong for some skin types.

Retinol products aren’t just skincare formulas to use when you want to target existing concerns — you can also use them as a preventative measure. Our favorite formula for prevention is the Naturium Retinaldehyde Cream Serum 0.05%, thanks to its gentle, cooling, and non-irritating formula that can be used by retinol beginners for wrinkle prevention.

We love this formula because it features retinaldehyde, which is a type of over-the-counter retinoid and is more potent than retinol itself. However, this formula may be too strong for some skin types. Ideal for prevention, this formula helps smooth out the skin’s texture and target fine lines and wrinkles while also delaying further creasing with regular use. It also works to revive skin texture and give it a smoother and more supple surface.

Pros
  • It comes in individual capsules, so you can dispense the ideal amount every time.

  • It combines squalane and algae oil to help nourish the complexion.

  • Since it’s formulated with a low retinol concentration, it’s on the gentler side.

  • It makes the complexion look and feel more supple.

Cons
  • The price tag is high compared to the others we tested.

For a firming effect, consider trying the Common Heir Retinol Serum, which comes in little capsules for each use. This luxe serum is formulated with a low 0.02% retinol concentration, giving it some of the benefits — like firming — of retinol without running the risk of irritation. It’s also enhanced with squalane and algae oil to provide lasting nourishment and improve skin elasticity.

After regular use, we noticed that our skin appeared smoother, more supple, and firmer. We also saw some radiance-boosting effects and felt like our skin really glowed after using this formula. Although it is an oil-based product, we love that the ingredients are non-comedogenic, so those with oily or combination skin types can still give it a go. The little capsules are convenient, but they are on the pricey side.

  • It doesn't make your skin sensitive to the sun, meaning you can use it morning and/or night.

Cons
  • This serum isn’t as potent as others we tested.

If you want a retinol alternative, consider a formula made with bakuchiol, which is just as effective as retinol with regular use (depending on the concentration) and is safe to use morning and night since it doesn’t make your skin sensitive to the sun. Our top pick for this category is the Biossance Squalane + Phyto-Retinol Serum; not only does it feature an excellent retinol alternative ingredient, but it also has niacinamide and squalane to calm and hydrate the complexion. While this product isn’t as potent as some of the other options on our list, we love this as an option for those who are sensitive to retinol or wish to use more plant-based formulas instead.

Things to Consider Before Buying Over-the-Counter Retinol Formulas

Concentration

To ensure the most effective retinol formulas, Dr. Jennifer Linder, M.D., F.A.A.D., board-certified dermatologist and Mohs surgeon as well as founder and Chief Medical Officer of Linder Health, says to check the concentration. “Retinol converts into retinoic acid and the conversion is ten-fold, so 0.25 to 1 percent stable retinol concerts to approximately 0.025 to 1 percent retinoic acid on the skin, which is typically what I would prescribe,” she explains. 

Packaging 

When shopping for retinol formulas, Dr. Carroll says to pay extra close attention to the packaging because “retinol is sensitive to light and air, which can degrade its effectiveness.” She recommends looking for products in air-tight, opaque packaging. And, since air and light are concerns, always make sure to keep your products sealed and never leave the lids off when not in use. 

Formula Type

Since retinol is available in various forms — think serums, moisturizers, gels, and creams — it’s also worth considering the formula type. “Serums deliver the active ingredient deeper in the skin, allowing faster results,” says Dr. Michele Green, M.D. board-certified cosmetic dermatologist. “However, serums may be too irritating for those with sensitive skin, so retinol creams are gentler and have the added benefit of moisture and hydration, which is ideal for dry and sensitive skin.” You can also try using another skin-smoothing, hydrating product, such as an Argireline serum or a niacinamide serum for more targeted areas, in conjunction with a retinol product.

Most of the best retinol formulas listed above are serums, including The Inkey List SuperSolutions 1% Retinol Serum, Shani Darden Skin Care Retinol Reform Treatment Serum, and Common Heir Retinol Serum. However, if you are looking for something that is cream-based, our top pick for the best over-the-counter retinol formula is the LilyAna Naturals Retinol Cream. We also love the L'Oreal Triple Power Anti-Aging Moisturizer for dry skin. 

Application

Retinol is a potent anti-aging ingredient that can effectively smooth fine lines and wrinkles, fade dark spots, and more. However, with its potency comes potential skin irritation, so Dr. Carroll says to also think about how you might apply the retinol formula, and if you’re new to it altogether, she recommends the sandwich technique. “The sandwich technique involves applying a layer of moisturizer to your skin, followed by the retinol product, and then another layer of moisturizer — this sandwiches the retinol between two layers of moisturizer, which can help reduce the potential for irritation and dryness.” 

In addition to application techniques, it’s also best to apply most retinol formulas — unless it’s a product with a retinol alternative like bakuchiol — in the evening since it can cause sun sensitivity. Additionally, Dr. Carroll says it’s vital that you apply sunscreen during the day when retinol is part of your regimen to help counter this sensitivity. 

How We Tested

First, the PEOPLE Tested team thoroughly researched the market to determine which over-the-counter retinol formulas were worth testing. We then conducted real-world testing of 32 popular retinol formulas over 12 weeks to better understand their quality, efficacy, and results.

  • Efficacy: Throughout the testing period, we took thorough notes on each product's performance, carefully considering the overall consistency, how well the formula layered with other skincare products, whether or not it addressed concerns such as fine lines, wrinkles, hyperpigmentation, acne, and dark spots, and the overall results after a three-month period. We tested these products on a variety of different age groups and skin types.
  • Rating: After the testing period was complete, we rated each retinol product on a one-to-five scale (five being the best) against the following testing attributes: absorption, consistency, feel, and appearance. The over-the-counter retinol formulas with the highest average ratings ultimately earned a spot on this PEOPLE Tested list.

Frequently Asked Questions

  • Is it okay to use retinol every day?

    If you’re new to retinol, Dr. Carroll doesn’t recommend using retinol every day. “Retinol can cause skin irritation, dryness, and peeling, especially in the initial stages of use,” she explains. With this in mind, she recommends using retinol two to three times per week to start and then gradually increase usage as your skin adjusts. 


    For those who have built up a tolerance, Dr. Linder says retinol is often tolerated once daily in the evening, but it depends on the specific formulation and an individual’s sensitivity level, so it’s best to ease into a new product before using it as often as every day. “Regardless of how often you use retinol, it is essential to use sunscreen during the day when using retinoids as they can increase the skin’s sensitivity to the sun,” Dr. Linder adds. With that said, if you do wish to use a retinol formula every day and are concerned about skin sensitivity, using a retinol alternative is always an option.

  • What is the best percentage of retinol to use?

    “Concentration of retinol typically ranges from 0.25 percent to one percent,” says Dr. Green. She explains that the best percentage of retinol to use depends entirely on your skin type and sensitivity. “Those with thicker and oily skin may tolerate a higher percentage better than whole with thinner and dry skin.” 

    No matter what your skin type and therefore potential tolerance level is, Dr. Green says it’s always best to start with a lower strength and gradually increase from there.


    If you're looking for a retinol formula with a lower concentration, we like Common Heir Retinol Serum. And, if your skin becomes irritated from retinol, the percentage is likely too high for your tolerance.

  • Is retinol a retinoid?

    Technically, retinol is a retinoid — however, there’s more to the story. “Retinoid is the umbrella term for retinol (the over-the-counter version) and prescription retinoids,” says Dr. Green. She explains that all retinoids are forms of vitamin A that are converted into retinoid acid when topically applied to the skin. The biggest difference between retinol and prescription retinoids is that retinol “contains lower concentrations of retinoic acid than prescription retinoids,” says Dr. Green.
