Helping to replenish moisture, the NIP+FAB Ceramide Fix Serum 12% improves the look of skin prone to dryness, redness and uneven texture. Its weightless, fast-absorbing formula layers easily into your morning or evening skincare routine, leaving skin feeling softer and smoother. Clinically proven to reduce transepidermal water loss (TEWL) within 48 hours, the formula helps skin retain essential moisture.* The advanced ceramide complex helps lock in moisture and support the skin barrier, while glycerin and squalane provide hydration. Niacinamide promotes a brighter, more even-looking complexion, and 2% azelaic acid helps refine the appearance of skin texture. An enrichment of biolin, a prebiotic ingredient, helps support the skin’s natural protective barrier, making this serum a useful addition to routines focused on hydration and skin comfort. *Independent clinical trial involving 33 subjects over 3 days.
