Plumps and Firms Skin – with Matrixyl 3000 and Syn-Tacks Dual Peptide

Matrixyl 3000 peptide mimics the effect of natural collagen to smooth and hydrate skin, while Syn-Tacks Dual Peptide adds targeted peptide activity to support reduction in the appearance of fine lines and wrinkles.

Regular use helps skin appear plumper and firmer, with a reduced look of fine lines, making it a practical step in an anti-ageing routine.

Suitable for Sensitive Skin – with a fragrance-free, gentle formula

Fragrance-free formulation lowers the risk of irritation and the product is labelled suitable for all skin types and cruelty-free.

Gentle composition makes the serum appropriate for morning and evening use for those prone to sensitivity, without adding unnecessary scent-based irritation.

Easy to Layer in Routines – with a smoothing, hydrating serum base

Directions advise applying a pea-sized amount after cleansing and after a hyaluronic acid serum, then patting into face and neck before following with a moisturiser and SPF in the morning.

Straightforward AM and PM application integrates neatly with existing hyaluronic acid and moisturiser steps, supporting consistent daily use.
