Facetheory Serum

If you're noticing fine lines, wrinkles, sun damage, and other signs of aging and hyperpigmentation on your face that you'd like to reduce, retinol can help. The only problem is that there is a seemingly infinite number of options out there that all promise to reverse these effects with dramatic results—and unfortunately, many don't live up to the hype.

When we saw the more than 2,000 reviews raving about the Facetheory Regenacalm Serum Pro, we took its list of ingredients to dermatologists to give us a better idea of whether or not this serum that says it "targets fine lines, wrinkles, blemishes, acne scars and hyperpigmentation" with a formula that includes retinol, vitamin C, liquorice extract, froehlich and lactic acids, would actually be effective.

Dermatologist Dr. Rachel Nazarian, M.D., F.A.A.D., told Real Simple that she thinks the serum is a "good product," explaining, "It uses some of my favorite tried-and-true ingredients in skin care." Dr. Nazarian said that retinol "is one of the classic ingredients to help with anti-aging because it stimulates collagen, improves texture and fine lines." She added that retinol has a tendency to dry out or irritate some skin types, but since this product "uses an encapsulated version that enhances absorption, it should make it more tolerable."

The serum is also formulated with froehlich acid, "which makes it even more effective," according to Dr. Nazarian, who said the ingredient will "make your skin look more even-toned with continued use." Plus, she explained that the lactic acid in the formula is "a gentle chemical exfoliant, so skin will feel smoother and softer with time, too." She also noted that, if you're going to use a retinol, "it's vital" to combine it with a "broad-spectrum sunscreen every morning," since the ingredient may make skin sensitive to sunlight.

Dr. Nazarian said that, given the powerhouse ingredients and effectiveness of this serum, it's at a "pretty good price point," which is made even more affordable with our exclusive discount code, MER30, that instantly takes 30 percent off. Plus, the serum is already on sale, so this code brings the price down even further to just under $17.

Dr. Debra Jaliman, board-certified NYC dermatologist, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai, and author of the book, Skin Rules: Trade Secrets from a Top New York Dermatologist, noted that the Regenecalm serum is "beneficial for anti-aging" because of its retinol inclusion and added that "vitamin C and licorice extract are great for pigment issues and scarring marks."

"Overall this serum helps with skin cell regeneration," Jaliman told Real Simple, explaining that it minimizes the look of fine lines and wrinkles.

And plenty of the more than 2,000 reviews agree. One shopper wrote that after using the serum for a month, their skin is "plumper and smoother," adding that "it's very gentle too, despite the retinol." Another said that they "absolutely love this product" and that they're "so happy" with the way the serum has improved their "sun damaged skin" that they've been recommending it to all their friends.

And a third shopper shared, "​​As soon as I started using this product, the wrinkles almost disappeared completely." They added that even though there is a high percentage of retinol in the serum, they agree with others who said "it's super gentle on the skin" and "simply amazing."
