What type of light can cause skin damage and aging?

UV light is known for its ability to penetrate the skin and cause significant damage, leading to premature aging and an increased risk of skin cancer. It encompasses two main types: UVA and UVB rays. UVA rays penetrate deep into the skin, causing photoaging such as wrinkles and sunspots, while UVB rays primarily affect the surface, leading to sunburn. Both types can contribute to the degradation of collagen and elastin, essential proteins for maintaining skin's structure and elasticity, thereby accelerating the aging process. Understanding the harmful effects of UV light is crucial for implementing effective sun protection strategies in cosmetology and skincare practices.
