Get To Know Ferulic Acid: The Most Underrated Anti-Aging Skincare Ingredient

So, what is ferulic acid anyway?

Hydroxycinnamic acid (or ferulic acid, for short) is a natural antioxidant that belongs to the phenolic acid group found in the cell wall of oats, fruits, plants, and peanuts. “Ferulic acid is a phytochemical, (a chemical created by plants to protect them),” says Ron Robinson, cosmetic chemist and founder of BeautyStat. The antioxidant works to neutralize free radical damage that accelerates the aging process, caused by exposure to the sun’s harmful UV rays and pollution. “Just as it works as a free radical scavenger in plant cells, it does the same when applied to our skin,” says Robinson. That's why the powerful antioxidant is commonly found in face serums, (like vitamin c serums and ferulic acid serums), but we’ll get to that later.

The many benefits of ferulic acid for skin

Ferulic acid is a powerhouse that, when applied as a topical serum or cream, protects skin against external aggressors responsible for early signs of aging—but it’s not Benjamin Button in a bottle, so it won’t repair damage that’s already done. It can, however, decrease signs of premature aging like fine lines and wrinkles, all while brightening your complexion and reducing the appearance of dark spots (AKA hyperpigmentation).

Another benefit? Fighting free radical damage. Our skin is susceptible to free radicals every time we step outside, due to ultraviolet UVA and UVB rays. “Because ferulic acid is both an anti-inflammatory and antioxidant, it helps protect the skin from oxidative stress caused by UV damage and pollution,” says Dafna Gershoony, PA-C, skincare lead at Ject. “Free radical damage is when environmental aggressors break down the DNA of skin cells,” says Robinson. Once free radical damage begins, it ricochets like the domino effect, damaging skin cells in its destructive path. “This can lead to wrinkles, sagging, and hyperpigmentation,” says Robinson.

That’s where ferulic acid comes in to protect your skin. “Ferulic acid absorbs harmful UV rays and prevents pollutants from breaking down collagen in the skin,” says Gershoony. Not only is it a powerful tool in anti-aging skincare, but it can also minimize the appearance of discoloration. “Because it also partially inhibits pigment producing cells, ferulic acid can brighten/reduce the appearance of sun damage and blemishes,” says Gershoony.

It’s even more powerful when combined with other antioxidant-rich active ingredients, like “L-Ascorbic Acid (pure vitamin C) which helps stabilize the ferulic acid,” says Robinson. It also increases vitamin C’s photoprotection (which is its ability to minimize sun damage). When ferulic acid comes in contact with vitamin A, vitamin C, and vitamin E, it boosts their effectiveness, making them even more beneficial in your beauty regimen, which is why many vitamin C serums contain a formulation with a combination of these ingredients (like the cult-favorite Skinceuticals C E Ferulic).

Who should use ferulic acid? Practically everyone.

The beauty of ferulic acid is that the majority of skin types can benefit from incorporating it into their skincare routine and will benefit from protection against environmental stressors, like the sun and pollution. By protecting your complexion with ferulic acid, you’re helping to keep your skin healthy, and according to Gershoony, “Healthy skin cells keep us looking brighter and younger.”

Side effects

Although there aren’t any side effects to using ferulic acid, if you have sensitive skin, it’s best to do a patch test before using any skincare products that contain the antioxidant. “People with sensitive skin may experience redness and peeling,” says Gershoony. A patch test will also ensure you aren’t allergic. “Those allergic to this acid can have redness, itching or hives and should discontinue use immediately,” says Gershoony.

While ferulic acid works well with vitamin C and vitamin E, it shouldn’t be mixed with alpha hydroxy acids or beta hydroxy acids, (like glycolic acid or salicylic acid). “When mixing these, it will alter the pH of ferulic acid and therefore decrease its effectiveness,” says Gershoony.

In order to maximize the benefits of incorporating ferulic acid in your skincare routine, use it on a daily basis in the morning after cleansing your skin, and before you apply moisturizer and sunscreen. Applying it as the first step in your skincare routine will help ensure your skin soaks it all up.

Ferulic acid can also can increase the effectiveness of retinol (and other vitamin A derivatives) but since retinol and vitamin C should not be mixed, it’s best to reach for a skincare product that already contains a combination of ferulic acid and retinol if you plan to use it during your evening skincare routine. Pro tip: use vitamin C in the morning and retinol at night.
