What it is: Formulated for skin that has lost its vitality and resilience, Skin Fortifier is infused with natural lipids to rebuild and strengthen skin's barrier of defence against moisture loss and external aggressors. The result is stronger, more resilient skin that's better equipped to fend off future damage. Helps repair and replenish skin's barrier Helps restore skin's ability to protect itself Helps keep moisture in and toxins out Who it's for: Loss of elasticity. Why it's different: Your skin's barrier is composed of three key lipids—Ceramides, Fatty Acids and Cholesterol—that protect against moisture loss and external aggressors. As you age, this barrier weakens and develops gaps that make skin more susceptible to damage. Rich in natural lipids like Muru Muru Butter, Olive Oil and Meadowfoam Seed Oil, Skin Fortifier helps fill in and reinforce skin's moisture barrier, making it stronger and more resilient. How to use it: Apply 2-3 drops on clean skin twice a day. Follow with your customised Bobbi Brown skincare regimen. Layer over Skin Reviver and Skin Moisture Solution to boost dull, dry skin. 14ml
