1. The essence of sunscreen products: Sunscreen products are mainly designed to protect the skin from UV damage, and their main function is sun protection, rather than beautifying or changing the appearance of the skin.
2. The definition of makeup: Makeup usually refers to the use of cosmetics to modify, beautify, or alter the appearance of facial, body, and other parts.
3. Conclusion: Regular sun protection is not considered makeup. Sunscreen is a part of skincare aimed at protecting skin health, not makeup.
