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

With a unique ability to attract and retain more than 1,000x its own weight in water, hyaluronic acid draws moisture from the lower layers of the skin into the upper layers to leave the complexion nourished and visibly supple.

THE SCIENCE BEHIND THE FORMULA

Peptides are short chains of amino acids, linked together by peptide bonds. There are 20 individual naturally-occurring amino acids which can be linked together in any order to give millions of different peptide combinations; with each helping to target different skin concerns. Recognising that peptides do so much more for the skin than simply boost collagen production, Medik8 has taken traditional peptide technology to the next level. Formulated with a unique, multi-beneficial blend of 10 different peptides at 30%, Liquid Peptides uses drone-targeted technology to ensure that each powerful peptide can dive deep into the skin to where it’s needed most, for maximum youth-boosting results.
