When it comes to tackling just about any skin problem—from fine lines and dark spots to uneven texture and breakouts—retinol is where it's at. It's one of a few vitamin A derivatives (aka retinoids) you can buy over the counter, often in the form of a serum.
Retinoids work by increasing cell turnover, offering mild exfoliation, and stimulating collagen production, explains board-certified dermatologist Diane Madfes, MD. "Retinol regulates our sebum production, which is great for acne control," she adds. "When used consistently, we also see a decrease in sun damage in the top layers of our skin."
Those clinically proven results are why retinol reigns supreme in the world of skincare. But which formula is right for you? We rounded up standout options touted by dermatologists, as well as a few fan favorites from the Byrdie team.
These are the best retinol serums you can order online.

What do buyers say? 82% of 1,000+ Amazon reviewers gave it 4 stars or above.
While over-the-counter formulas aren’t as strong as the prescription variety, Fusion PM holds its own. “I like this because the retinol is encapsulated and combined with vitamins C and E,” says Dr. Madfes.
This serum flaunts a generous 1.5 percent concentration of encapsulated retinol, meaning it releases slowly into your skin to sidestep irritation. In addition to the brightening antioxidants Dr. Madfes mentioned, she notes that the base is “very hydrating” thanks to the blend of humectants and skin-loving squalane, so you’re less likely to notice any dryness and inflammation from the retinol.

Final Verdict
Peter Thomas Roth Fusion PM is, hands down, the best retinol serum. The dermatologist-recommended formula contains 1.5 percent encapsulated retinol, plus brightening antioxidants and moisturizing squalane. However, if you want something a bit more affordable, you can't go wrong with The Inkey List Retinol Serum, an award-winning formula containing two retinoids, squalane, and hyaluronic acid.
What to Look for in a Retinol Serum
Retinol Form
When shopping around, you'll see serums containing various forms of retinol, as well as some other over-the-counter retinoids. Dr. Madfes recommends encapsulated retinol (sometimes called sustained-release retinol), as it offers a slower release into the skin, which helps minimize irritation and excessive dryness.
You'll also find various retinoid complexes, which means multiple forms are combined into one. Then there's retinal (aka retinaldehyde), which has shown to be a little more effective than traditional retinol while still avoiding prescription-level side effects.
Concentration
Over-the-counter formulas usually contain about 1 percent retinol, though you'll find some lower and higher strengths. While OTC serums typically max out at 2 percent, they can go higher, depending on the form of retinoid used. Higher concentrations generally provide faster, more noticeable results, but if you have particularly sensitive skin, a lower concentration may be best.
Hydrating and Soothing Ingredients
Since retinoids can cause dryness, Dr. Madfes says, "the trick is to create a balance to not dry the top layer of our skin." She recommends formulas with hydrating ingredients like hyaluronic acid, glycerin, squalane, niacinamide (vitamin B3), ceramides, and plant oils.
Another common side effect is irritation. To minimize stinging and redness, opt for retinol serums containing soothing ingredients, such as chamomile, aloe, witch hazel, and green tea. Squalane and various plant oils can also offer a calming effect.
