Keratin is a protein that is essential for healthy skin. It plays a crucial role in maintaining the skin's barrier function, protecting it from environmental aggressors like pollution and UV radiation. Keratin strengthens the epidermal layer, making the skin more resilient and reducing the risk of damage and premature aging.
However, keratin can also contribute to skin problems in certain cases. For example, keratin plugs, also known as closed comedones, can form when keratin builds up in hair follicles, leading to acne. Additionally, some individuals may experience inflammation and irritation due to keratin buildup, especially when dealing with scars.
In conclusion, keratin is generally beneficial for skin health, playing a vital role in its strength and protection. However, excessive keratin buildup can contribute to certain skin conditions, making it important to maintain a balanced approach to skincare.
