Key Ingredients
Matrixyl® 3000 (pronounced 'ma-TRIX-ul 3 thousand')

A combination of peptides which 'trick' the skin into producing more collagen for visible firming, plumping and wrinkle-smoothing results.

Drone-Targeted Copper Peptide

Encapsulated in a polymer system, it dives through the layers of the skin to specifically support collagen-producing cells.

Expression Line Peptide

An innovative peptide which works to tackle the appearance and formation of expression lines by helping to block the pathway that leads to facial muscle contraction. This leaves the skin visibly smoother and more youthful-looking.

Carnosine (pronounced 'CAR-no-seen')

A protective peptide that is naturally produced in the body, carnosine helps to block skin-damaging sugars from binding to collagen in the skin, therefore minimising the visible formation of wrinkles.

Expression Line Peptide

Multi-Weight Hyaluronic Acid (prounounced 'Hiya-le-ronick')

With the ability to attract and retain more than 1,000 times its own weight in water, multi-weight hyaluronic acid draws moisture into multiple layers of the skin; leaving the complexion deeply hydrated and visibly supple.

Yes. Liquid Peptides can be applied straight after an exfoliating acid, in both your AM and PM routines.
