What is the reason for using a broad-spectrum sunscreen in cosmetology?

Using a broad-spectrum sunscreen in cosmetology is essential because it offers protection against both UVA and UVB rays. UVA rays penetrate the skin more deeply and can accelerate skin aging and increase the risk of skin cancer, while UVB rays are primarily responsible for sunburn and can also contribute to skin cancer. By using a broad-spectrum sunscreen, cosmetologists ensure comprehensive protection, which is crucial for maintaining healthy skin and preventing long-term damage.

Considering the other options, enhancing skin hydration, improving skin texture, and providing an instant glow are beneficial aspects of various skincare products, but they do not address the primary purpose of sunscreen. Sunscreens are specifically formulated to filter harmful ultraviolet radiation, making broad-spectrum protection the key reason for their use in cosmetic practices.
