What are free radicals and how do they impact the skin's health and appearance?

Free radicals are unstable molecules that can damage skin cells and accelerate the aging process. They are often caused by factors like UV radiation, pollution, and smoking. When free radicals interact with skin cells, they can lead to wrinkles, fine lines, and other signs of aging. Using antioxidants in skincare products can help neutralize free radicals and protect the skin from their harmful effects.
