The newest retinol cream from RoC is their Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 ($18.39, Drugstore.com). A combination of vitamin C (as L-ascorbic acid), glycolic acid, and retinol, this product claims that it will diminish expression lines, deep wrinkles, and improve skin’s overall softness and smoothness.
The good news about RoC Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 is that it appears to provide a fairly high concentration of vitamin C. According to a review in the International Journal of Pharmaceutics, vitamin C has many favorable aspects for the skin, including the scavenging of free radicals (reacts with the superoxide anion or the hydroxyl radical), suppressing pigmentation of the skin (by inhibiting the enzyme tyrosinase), decomposing melanin, triggering collagen production and thereby increasing skin firmness, and enhancing sunscreen protection — all great for a morning moisturizer!
The bad news about RoC Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 is two-fold. The first is that it combines an AHA (glycolic acid) with retinol in the same formulation, which is an unstable combination. In fact, Dr. Leslie Baumann, dermatologist, author of The Skin Type Solution, and chief of the department of cosmetic dermatology at the University of Miami, verifies that AHAs and retinol should not be used together in her blog: “Retinol is a highly effective ingredient, but it is unfortunately not a terribly stable one! Alpha hydroxy acids (such as glycolic acid and lactic acid) inactivate retinol, and the two should not be used together.”
The second bit of bad news about RoC Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 is that the already de-stabilized retinol is in low concentration. Actually, seemingly very low concentration; although the exact percentage is not provided, it is listed between propylparaben and sodium hydroxide, indicating that retinol is most likely in or below the 0.025% range. (Of course, I cannot know this number for certain, and am just making an educated guess!)
Of course, RoC Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 is not all bad – as a vitamin C cream and a source of sunscreen, it comes in a dark container with a relatively small opening at the end, so the vitamin C will not oxidize as quickly as in other formulations, and the chemical sunscreen is quality (3% avobenzone, 10% homosalate, 3% octocrylene, 5% oxybenzone). Unfortunately, if you are buying RoC Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 looking for the effects of retinol, I would recommend buying a different cream altogether with a reported high concentration of retinol, like the 0.6% retinol in Green Cream Level 6. I would also recommend using retinol creams only at night, since retinol makes the skin sensitive to the sun. Overall, however, RoC Retinol Correxion Deep Wrinkle Daily Moisturizer SPF 30 is not a bad moisturizer, but certainly a poor source of retinol! Overall rating: 5.5/10 (High concentration of proven ingredients: 1.5/3. New technology: 1.5/3. Value for the money: 1.5/3, because you’re not even getting much retinol, and it’s listed in the product name. Sunscreen: 1/1.)
