PRODUCT DETAILS

Hello, barrier support. Dual Barrier Boosting Serum brings lightweight hydration to your routine while helping soothe and calm signs of sensitivity. That balance keeps the experience focused: hydration and calming care in a lightweight formula.

At the heart of the serum, five ceramides moisturize and support the moisture barrier. Aquatide, a featured patented peptide, adds another layer of moisture-barrier support, making both ingredients central to the serum's barrier-focused story.

Panthenol moisturizes and eases the look of redness, while Biosaccharide Gum-1 helps smooth skin texture, calm the look of redness and provide long-lasting hydration. Together, they broaden the serum's care from barrier support to soothing hydration and a smoother feel.

The serum is intended for normal, dry, oily, combination and sensitive skin, including extra-sensitive skin. The formula is free from fragrance and essential oils.
