Clarifying Serum
Serum · 16 ingredients
A clarifying serum formulated around anti-inflammatory principles, designed to calm and refresh the complexion over time. Albatrellus Ovinus extract works to reduce redness and skin sensitivity, while Bistort Root extract helps promote a more radiant appearance. Hyaluronic acid rounds out the formula by drawing moisture to the skin, leaving it looking refreshed. The serum suits those dealing with visible irritation, sensitivity, or dullness, and supports the skin's natural barrier function with continued use.
