SkinCeuticals Hyaluronic Acid Intensifier Multi-Glycan

Yes — plumping and softening fine lines is exactly what it is designed for. It boosts your skin's own hyaluronic acid by 30% and, in testing, filled the look of fine lines by 24% while instantly plumping and improving radiance. Over 12 weeks, 97% of users agreed their skin felt more supple.

Multi-Glycan is the reformulated, upgraded version of the original HA Intensifier. It keeps the same beloved hydrating base but adds a post-biotic ferment, liquorice root and purple rice extracts, and 20% more Proxylane, plus a third (acetylated) form of hyaluronic acid for deeper penetration — giving longer hydration, more plumping and better fine-line filling.

Glycans (glycosaminoglycans) are naturally occurring compounds that give skin its structure, hydration and plumpness — hyaluronic acid is one of them. They decline with age, leading to volume loss and wrinkles. Multi-Glycan is designed to boost your skin's glycan content to help restore plumpness and fullness.
