Key Ingredients:
Matrixyl® 3000
A unique combination of peptides which ‘trick’ the skin into producing more collagen for visibly plumping, firming and wrinkles-smoothing results.

Drone-Targeted Copper Peptide
Encapsulated in a polymer system, it dives through the skin’s layers to help support collagen-producing cells.

Expression Line Peptide
Working to tackle the formation and appearance of expression lines, this innovative peptide helps to block the pathway that leads to facial muscle contraction for a visibly smoother and more youthful-looking complexion.

Carnosine
Naturally produced in the body, this protective peptide helps to block skin-damaging sugars from binding to collagen; minimising the formation of wrinkles.

Multi-Weight Hyaluronic Acid
An incredibly hydrating ingredient, hyaluronic acid attracts and retains more than 1,000 times its own weight in water and draws moisture in the upper layers of the skin; leaving it looking visibly supple and deeply hydrated.

Rated 4 out of 5 by from Peptides serum I would say this is a good serum, I used it only once so maybe my opinion is not objective. It was feeling good on my skin and helped me during winter with dryness but I cannot comment on how it worked on fine lines and wrinkled

Rated 4 out of 5 by from Light serum Feels good on skin but not any better than cheaper serums. Will be interesting to see if it delivers results as it claims.
