If you’re looking to make significant changes to your skin, whether that be reducing fine lines or combatting dark spots, retinol is one powerhouse ingredient—but finding the right retinol product for your skin type is no easy task. For example, those with dry or sensitive skin may want to use gentler derivatives buffered with hydrating actives; on the flip side, acne-prone individuals may need a stronger, sometimes prescription-strength formula. 

And then there are those that fall somewhere in between—ever wished there was a middle ground? Well, you’re in luck: Retinaldehyde may be the answer.

Like other forms of retinol, retinaldehyde is a great ingredient to encourage healthy skin aging and may be effective for treating acne as well, especially when used alongside an exfoliating active, such as glycolic acid. (Just not on the same night! That’s a recipe for irritation.) “As a retinoid, [retinaldehyde] helps to regulate skin cell turnover, preventing pores from becoming clogged, as well as improving overall skin tone and texture while boosting collagen production,” Garshick adds. 

Many people look to prescription-strength retinoids for acne treatment, and for a good reason: These formulas (most notably tretinoin) are stronger than OTC options. But some people, especially those with sensitive skin, may not be able to tolerate prescription-strength products, as they can be drying and irritating. For many, retinaldehyde functions as a strong (yet not too strong) middle ground. 

Of course, there are tons of OTC products out there—to streamline your search, we asked board-certified dermatologist Rebecca Marcus, M.D., how to spot a winning formula. “Formulas that contain skin barrier-boosting and hydrating ingredients, such as glycerin, ceramides, and hyaluronic acid, will help to make retinaldehyde more tolerable,” she says, especially if your skin already runs a little sensitive. 

So the best practice is to pair this powerful active with hydrating ingredients to simultaneously pamper your skin barrier. Our pick? The Youth to the People Retinal + Niacinimide Youth Serum, which combines niacinamide, essential ceramides, and adaptogens to buffer the potent active and provide even more antioxidant support. 

That being said, any form of vitamin A may cause irritation, especially if used incorrectly. If you haven’t used any form of retinol before, it’s best to start with a more gentle product and work your way up. “If you ‘start low and go slow’ (start with a gentle retinoid and slowly work your way up to a stronger one), most people will be able to have a long and happy relationship with retinoids that will keep their skin looking fresh and smooth,” Marcus says. Meaning, retinaldehyde may not be for you if you haven’t tried any form of retinol before. If this is the case, it’s best to start with a super-gentle retinol serum. 

You’ll want to apply your retinaldehyde serum at night to dry, clean skin (a general rule of thumb for any type of retinol). Use a pea-size amount to avoid irritation, and apply the product to both your face and your neck. 

Again, the most important thing to remember when applying any retinoid is to ease your way into it, as using the serum every night right off the bat is more likely to cause irritation. Most derms recommend starting with a once-a-week cadence, gradually increasing to everyday use as tolerated.  

In addition, make sure you’re limiting other active ingredients in your nighttime routine when using retinaldehyde. “Avoid mixing other acids, such as vitamin C or AHAs, in the same product or even in different products used at the same time,” Marcus says. Don’t worry: You can still use your favorite exfoliating serums, just not on the same night. (Here’s a derm-approved skin-cycling routine if you need help shuffling through your actives) You don’t have to ditch your vitamin C serum either—simply use it in the morning.
