Your skin barrier, the outermost layer of the epidermis, is your first line of defence against the environment. It keeps moisture in and irritants out.
When the barrier is compromised, skin becomes dry, sensitive, and reactive. Harsh cleansers, over-exfoliation, and environmental stress are common culprits.
GHK-Cu supports barrier repair by stimulating the production of structural proteins and lipids that hold the barrier together. Unlike ingredients that strip or exfoliate, it works with your skin's natural repair mechanisms.
Building a routine around barrier health (gentle cleansing, targeted treatment, and nourishing moisturisation) is one of the most effective things you can do for long-term skin health.
