What is the primary indication for using sunscreen daily?

The primary indication for using sunscreen daily is to protect against UVA and UVB rays. Sunscreen is designed to shield the skin from the harmful effects of the sun's rays, which can lead to various skin issues, including sunburn, skin aging, and an increased risk of skin cancer. UVA rays penetrate the skin more deeply and contribute to premature skin aging and the formation of wrinkles, while UVB rays are primarily responsible for sunburn.

By applying sunscreen, individuals can significantly reduce their risk of sun damage and its associated consequences. Incorporating sunscreen into a daily skincare routine is essential for maintaining overall skin health and preventing long-term damage due to sun exposure. Other benefits, such as enhancing makeup application or reducing fine lines, may occur as a result of using sunscreen but are secondary to its primary role of sun protection.
