SUPREME SKIN 7 50ml

A peptide is a short chain of amino acids, the building blocks of proteins such as collagen and elastin in the skin.

In skincare, peptides act as messengers. They signal the skin to support processes like firmness, elasticity, and repair. When applied topically, certain peptides can help improve the appearance of fine lines and strengthen the look of the skin over time.

Think of peptides as communication tools, encouraging the skin to function in a way that supports resilience, smoothness, and overall structure.

Very important.

Serums deliver targeted actives, but they don’t seal them in. SUPREME SKIN 7 is designed to lock in hydration, reinforce the skin barrier, and prevent transepidermal water loss, which is essential after layering treatments.

Without a moisturiser, the actives you’ve applied can evaporate or become less effective. Finishing with SUPREME SKIN 7 ensures:

Improved moisture retention

Stronger barrier support

Better tolerance of active ingredients

A smoother, more balanced finish

Think of it as the step that completes the system, not just another layer, but the one that holds everything together.

Overnight, your skin naturally forms an acid mantle, a protective layer made up of sebum and beneficial lipids that help maintain barrier function and microbiome balance.

In the morning, this protective layer does not require active cleansing. For most skin types, simply rinsing with water is enough before applying your treatment products.

We recommend the following morning approach:

Rinse → Essence → Serums → Moisturiser → SPF

Night-time is when active cleansing is essential to properly remove SPF, makeup, pollution, and daily buildup.

This philosophy supports long-term barrier health rather than over-stripping the skin.
