Retinol is as close as it gets to a do-it-all topical skin care ingredient; dermatologists love its ability to boost skin cell turnover and spur the production of collagen (collagen being the fiber in skin that keeps it firm and smooth). Plus, it has ample data to back up its efficacy. But retinal, which belongs to a group of ingredients called retinoids (that also includes retinol), might be able to surpass it. Short for retinaldehyde, retinal is even more powerful than retinol, with the similar ability to smooth skin texture, clear breakouts, even out skin tone and soften fine lines and wrinkles. Retinoids are vitamin A derivatives that you can use for acne, wrinkles and hyperpigmentation, says Dr. Gloria Lin, a board-certified dermatologist at Schweiger Dermatology in New York City. Some are only available by prescription (often bucketed under the term “retinoids”), while you can find other over-the-counter options at a lower strength, with retinal being the most potent of these, she says.
