Hyaluronic Acid vs Retinol
Which is right for your skin?
Not rivals: hyaluronic acid hydrates and plumps with zero irritation, while retinol actively renews skin but can dry it out. The classic move is to use retinol for results and hyaluronic acid to buffer the dryness it can cause — together, not instead of each other.
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Speeds up how fast your skin renews itself so old, dull cells shed faster and fresher skin shows through. Builds collagen over time, smoothing fine lines.
