01
What it is
Proteoglycans combine a core protein with glycosaminoglycan chains. In cosmetics, they are of interest in formulas designed for comfort, hydration and an improved surface appearance.
02
Its role in a formula
They are incorporated into complex formulas and should not be confused with directly replacing deeper skin structures. Cosmetic function depends on origin, processing and vehicle.
03
How to use it
Use them within a simple routine: gentle cleansing, treatment, moisturiser if needed and daily sun protection. Assess comfort and skin appearance over time.
