Why it works: “Topical collagen provides an immediate cosmetic benefit,” Parsa said. “It helps hold moisture, smooth the skin’s surface and temporarily soften the appearance of fine lines.” Most topical collagen is made from animal sources like cows, pigs and fish, so read labels carefully if you have concerns about non-vegan products. There are also plant-based alternative collagen products that use seaweed or plant protein hydrolysates, which are mixtures created by breaking down plant proteins like soy or wheat. As you’re reading labels, you may also find other ingredients that support collagen production, such as amino acids, vitamin E or botanical extracts.
