This Ingredient Reduces The Appearance Of Wrinkles — Reviewers Rave About It Too

Hyaluronic acid can play a vital role in almost anyone's well-rounded skin care routine. The compound is a humectant naturally found in the body, the skin in particular. In fact, about 50% of the body's total amount of hyaluronic acid resides in the skin1, but it's also present in tissues, joints, and blood vessels.

Hyaluronic acid's primary role in the skin is water retention: As a humectant, It attracts and holds water. It's so strong, in fact, that it can hold up to 1,000 times its weight in water1. And in doing so, it keeps the complexion dewy, moisturized, and plump. 

When taken via supplementation, research has found that it can be hugely beneficial for skin hydration and helps to ease the appearance of fine lines and wrinkles.* In fact, one double-blind, placebo-controlled study found that participants who took HA supplements experienced a reduced appearance of wrinkles after only eight weeks2—with improved "skin luster" at 12 weeks.*

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 elasticity3.* (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 higher4 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 a significantly smoother appearance of wrinkles.*
