What are the anti-aging benefits of using topical antioxidants with retinol?
Our skin - the largest organ in the body - performs many important physiological functions and is particularly susceptible to free radical damage. Skin acts as the primary barrier against fluid loss and environmental abuse, and is constantly exposed to ultra-violet (UV) light and other oxidative stressors. This free radical damage causes wrinkles, loss of skin tone and elasticity, hyperpigmentation and aging. The face, neck, décolleté and hands are the most exposed and vulnerable parts of the body. Therefore, they require additional, targeted antioxidant protection considerably more than the unexposed areas of the skin.
It is particularly important to apply topical antioxidants to the exposed areas to prevent and reverse sun damage, and to improve the overall health of the skin. Countless studies demonstrate that topical antioxidants protect the skin from UV damage, reduce inflammation and increase collagen production. The use of topical products that contain Vitamins C and E, the most well known and effective antioxidants, are essential for skin's health, and together they provide extraordinary antioxidant protection.
But using only a topical antioxidant may not be enough for optimum skin rejuvenation. Retinol, a biologically active form of Vitamin A, plays an important role in that the skin rejuvenation process. As a result of chronological and environmental aging, our skin's ability to renew itself slows down significantly. Retinols accelerate exfoliation and stimulate epidermal turnover by replacing the damaged cells with new cells, therefore, increasing epidermal thickness. Studies have shown that retinols and Vitamin C are equally important in the production of new collagen since they use different mechanisms to synthesize it. In addition, retinols and Vitamin C help to reduce hyperpigmentation and age spots, and improve overall skin tone and texture.
As you can see, both topical antioxidants and retinols have a specific role in an anti-aging regimen. When combined, they produce the most comprehensive and effective results.
