Collagen
Collagen is an important building block when it comes to the formation of skin, bone, and cartilage, and you’ve probably seen it touted as a must-have beauty supplement. Collagen is naturally found in food sources such as chicken, fish, and eggs, but supplementation might be needed to replace the collagen that is naturally lost through age. Taking collagen supplements is associated with fewer and less noticeable wrinkles, though more research is needed to fully determine how the protein works.
Bakuchiol
Sensitive to retinol? Try bakuchiol, a collagen-stimulating extract that comes from the seeds of a plant used for Ayurvedic medicine in India. Still a relatively new anti-wrinkle ingredient, topical bakuchiol shows promise for helping with a range of skin concerns, including sun damage, wrinkles, and acne—without the risk of irritation that comes from treatments like retinol.
