The core capability of Vitamin E is antioxidant, which lays the foundation for all its effects.
1. The 'Antioxidant Guardian' in the Field of Skin Care
• Mechanism: Sacrificing itself to prioritize combining with free radicals generated by ultraviolet rays, pollution, etc., protecting skin cells, collagen, and elastic fibers from oxidative damage.
• Effects:
◦ Anti-aging: Prevent and fade fine lines and wrinkles caused by photoaging.
◦ Brighten skin tone: Reduce lipid peroxidation, helping to improve dullness and achieve a more even skin tone.
◦ Enhance sun protection: Synergize with Vitamin C to provide endogenous photoprotection for the skin, one of the golden rules in daytime skincare.
2. Moisturizing and Repairing the Skin Barrier
• Mechanism: As a lipid, it can fill the gaps between skin keratinocytes to form a protective film.
• Effects: Effectively reduce trans epidermal water loss, enhance skin barrier function, especially suitable for dry skin and skin with a compromised barrier.
3. Classic Synergistic Effect: 'Regeneration' Cycle
• Mechanism: After Vitamin E neutralizes free radicals, it loses its activity. However, Vitamin C can 'regenerate' Vitamin E, restoring its antioxidant capacity.
• Effects: When combined (such as in the classic 'CEF' serum), they form a powerful and sustainable antioxidant cycle, with an effect greater than the sum of their parts (1+1 > 2).
4. Anti-inflammatory and Soothing
• Mechanism: Inhibit the release of inflammatory factors.
• Effects: Help soothe irritated skin, accelerate post-sun repair, and relieve itching and discomfort caused by dryness.
