This is your high-performance, barrier-first serum for reactive midlife skin that’s constantly under stress from hormones, weather, and everyday life. It’s made for people in their 40s, 50s, and beyond whose skin has thinned, become more sensitive, and now reacts to almost everything.

At its core is 3% ectoine—nature’s stress-protection molecule found in microorganisms that thrive in extreme environments. It forms a protective hydration shell around skin cells and binds water so skin stays calm and hydrated, even in harsh conditions. 3% bakuchiol plus a six-active complex of 15% vitamin C, niacinamide, peptides, and hyaluronic acid work together to visibly brighten, refine texture, smooth the look of lines, strengthen a compromised barrier, and lock in moisture.

Your skin will look and feel brighter, smoother, and more even-toned, with fewer flare-ups and softer lines. Dry, irritated patches get deeply hydrated, oily zones behave, and your barrier becomes more resilient and less reactive—so you can rely on fewer products, not more.

In clinical studies, ectoine has been shown to reduce transepidermal water loss by up to 40%, reduce wrinkle depth by 19%, and increase collagen production by 23%, delivering visible anti-aging benefits across all subjects. Schaf is among the first Canadian brands to use clinical levels of ectoine in a performance-based serum for reactive midlife skin. The formula is minimalist, barrier-first, pH-balanced, and completely free from fragrance, essential oils, and other common barrier-disrupting irritants.

What it Does:

• Helps skin cope with daily stressors like hormones, weather, and pollution.
• Visibly brightens and evens out tone for a more awake, refreshed look.
• Smooths the look of fine lines and improves skin texture.
• Strengthens a compromised barrier so skin becomes less reactive.
• Delivers deep, long-lasting hydration to dry, irritated patches.
• Helps oily zones behave so you can rely on fewer products, not more.
