Level 4 is the category-defining maximum — 8000 IUs of retinol, buffered to perfection for change without irritation. For skin showing significant aging, from lost firmness to deep wrinkles, the retinol is encapsulated into a formula with niacinamide and Vitamin D and Vitamin F that repairs collagen and elastin and accelerates cell renewal at every layer. Low-molecular-weight hyaluronic acid sustains hydration through nightly use; over time, texture softens and firms and tone grows more even.
