Properties
Anti-inflammatory: Boosting the skin's immune defences;
Depigmenting, lightening: Inhibiting the activity of tyrosinase, an enzyme responsible for the production of melanin, in order to reduce the appearance of brown spots;
Firming, plumping: Inducing the production of Type I collagen and functional elastin to compensate for their loss, and preventing their degradation by interfering with the enzymatic processes that break them down (metalloproteinases);
Regenerating: Increasing the proliferation of epidermal keratinocytes to strengthen the skin's barrier function against external factors and prevent water loss.
