If you've tried it all—night cream
, anti-aging moisturizer
, and face serum
—but you're still showing signs of aging, don't just slap on a heavy-duty foundation
and call it a day. Instead, it might be time for the gold standard in anti-aging: Retinol. The over-the-counter vitamin A derivative clears acne flare-ups, evens out skin tone and texture, stimulates collagen, and minimizes age spots and wrinkles. "Retinol is the only medication that has scientifically-proven anti-aging properties," says Tsippora Shainhouse
, a board-certified dermatologist in Los Angeles.
Best for Building Collagen: Renewl Retinol
This retinol serum helps build collagen, which diminishes fine lines and wrinkles, smoothes the skin, and hydrates all at the same time, says Anna Guanche, a board-certified dermatologist at the Bella Skin Institute. This product is great for beginners, too, since it has a smaller concentration of retinol. Once your skin adjusts to your new regimen, opt for the brand's more powerful formula.
