In my research on chapped skin care, I've discovered the essential role collagen plays. Collagen, a protein found naturally in our bodies, offers hydration and elasticity to the skin, helping to prevent dryness and chapping. When the skin's collagen levels decrease, it can lead to dry, chapped skin. Therefore, maintaining collagen levels is crucial, and can be achieved through a healthy diet, good skincare routine, and possibly collagen supplements. So, collagen is definitely a key player in keeping our skin healthy and free from chapping.
