["[\"Helps soften the look of fine lines and rough texture\",\"Supports a firmer, more elastic-looking finish\",\"Leaves skin smooth and comfortably conditioned\"]"]

A silky firming serum that helps skin look fuller, smoother, and more lifted when bounce starts to dip. Collagen, retinol, and squalane work together to support a more elastic-looking surface while softening the look of fine lines and roughness.

The texture stays comfortable and polished on skin, making it a strong evening step for routines focused on firmness, glow, and a smoother-looking finish.

Best for: an evening routine focused on the look of fine lines, roughness and reduced bounce. Choose it over a basic hydrating serum when retinol is the priority.
