Firms & Restores

$42.00

Our peptide-rich serum, powered by Copper Tripeptide-1 (GHK-Cu), Irish Moss, and Niacinamide to help skin look visibly firmer and more even. Helps reduce the look of fine lines and delivers lasting hydration for a smoother, more youthful-looking complexion.

Quantity

Best if you're starting to see loss of firmness — Copper Tripeptide-1 (GHK-Cu) is one of the most researched peptides in skincare, for skin that looks less bouncy than it used to.

Best for sensitive skin that can't tolerate retinol — Peptides work gradually and without the irritation, purging, or sun sensitivity.

Best if you want results over months, not days — Peptides build slowly. Give it 8–12 weeks of consistent use.

Best layered under moisturizer, AM or PM — Lightweight, absorbs fast, plays well with the rest of your routine.

Apply 1–2 pumps to clean skin, morning and night. Follow with moisturizer.
