And while the 100 mg of HA greatly contributes to its hydration-enhancing efficacy, the other ingredients also play a huge role.*
The most obvious is the powder’s namesake: collagen. Collagen peptides have been shown to enhance hydration, support firmness, and promote elasticity.* (Please check out our guide to collagen for more info on how.) For example, one double-blind, randomized, placebo-controlled clinical trial found that participants’ moisture levels in the skin were seven times higher than those who did not take collagen supplements.*
Even better, when collagen and HA work together, studies show they improve the appearance of the skin: One double-blind, randomized, placebo-controlled clinical trial found that when a small group of women took a collagen supplement that was also formulated with hyaluronic acid and a few other actives, they experienced significantly smoother appearance of wrinkles.*
Reviewers note the changes in their skin: “My skin is firm yet supple to the touch,” says Rosalina. And Cynthia B. says, “I have been taking it for about 30 days now, and I feel better and my skin looks fresher, which is saying something at 59 years of age. Thank you for the thoughtful nutritional product.”*
