THE SCIENCE OF SKIN AGEING
Learn how oxidation, glycation and carbonylation influence visible skin ageing and why astaxanthin sits at the heart of every CUTISÉ formula.
THREE HIDDEN PROCESSES
Skin changes gradually as environmental exposure, lifestyle and normal biology place stress on cells, proteins and the skin barrier.
Free radicals react with skin cells, lipids and proteins, contributing to dullness and visible ageing.
Excess sugars can bind to proteins such as collagen, making them less flexible over time.
Reactive carbonyl compounds can alter proteins and lipids, affecting texture and resilience.
WHAT IS OXIDATION?
When oxygen reacts with the apple, its colour and structure begin to change. Skin also experiences oxidation. UV exposure, pollution, stress and normal metabolism can generate free radicals. When free radicals outnumber the skin’s antioxidant defences, oxidative stress occurs.
Sun, pollution and everyday stress increase free-radical formation.
These unstable molecules seek electrons from nearby cells and proteins.
Damage builds when free radicals exceed the skin’s natural defences.
Over time, skin may appear duller, less even and less resilient.
THE OXIDATIVE STRESS CYCLE
Free radicals are unstable molecules. In small amounts they are part of normal biology. Problems arise when too many accumulate and begin reacting with healthy cells, lipids and structural proteins.
UV, pollution, stress and normal metabolism.
Unstable molecules seek electrons from nearby structures.
Lipids, proteins and cell membranes can be affected.
Skin may look duller, rougher and less resilient over time.
MEET ASTAXANTHIN
Astaxanthin is a naturally occurring pigment found in certain microalgae and marine organisms. In nature, it helps organisms manage environmental stress. In skincare, it is valued for antioxidant activity and its compatibility with lipid-rich structures such as cell membranes.
YOUR SKIN'S DEFENCE SYSTEM
Think of antioxidants as a response team. They can neutralise certain free radicals before those molecules continue reacting with nearby cells and proteins. Antioxidants complement, but not replacedaily sunscreen and healthy lifestyle habits.
Help stabilise reactive molecules.
Support cell membranes and skin lipids.
Help reduce oxidative pressure on collagen and elastin.
Complement sunscreen and a consistent routine.
WHY CUTISÉ CHOSE IT

THE CUTISÉ APPROACH
Every CUTISÉ formula combines astaxanthin with complementary ingredients selected for a clear purpose, from cleansing and hydration to brightness, comfort and visible vitality.
No single ingredient can replace the basics. The most effective approach combines sun protection, healthy habits and a consistent skincare routine.
Use broad-spectrum SPF and reapply when needed.
Fruit and vegetables provide a range of dietary antioxidants.
Sleep supports normal repair and recovery processes.
Support overall wellbeing and skin comfort.
Smoking increases oxidative stress and accelerates collagen breakdown.
High sugar intake can contribute to glycation.
Apply antioxidant skincare consistently as part of your routine.
Regular movement and relaxation can support overall wellbeing.
