Detailed answer

It is important to protect your lips from the harmful effects of UV rays, just like you would protect your skin. Choose a sunscreen with SPF specifically formulated for lips, as regular sunscreen may not be safe for ingestion. Apply a thin layer of lip sunscreen to your lips daily, especially when spending time outdoors. Reapply every few hours or after eating or drinking. Look for lip balms or sticks that contain ingredients like zinc oxide or titanium dioxide for effective sun protection.
