First Care Activating Serum

What it is: A reformulation of Sulwhasoo's iconic best-selling K-beauty serum that is the coveted step for a visibly smooth and glass-like glow.

What it does: Backed by 23 years of research and new data-mining technology, this formula delivers the perfect combination of ingredients for optimized anti-aging and hydrating benefits. This luxurious formula hydrates, nourishes and visibly firms skin while boosting the absorption of subsequent products applied on top. The secret is in the JAUM Activator, a masterfully blended complex of five precious herbs that improve the look of skin's hydration, brightness, radiance, translucency, visible wrinkles and moisture barrier. The new formula delivers everything the previous formula offered by with improved anti-aging benefits that help make your skin more radiant than ever.
