Overview
Facts about Sunscreen
- Sunscreens with a broad-spectrum label help shield your skin against UVA and UVB rays.
- There are two types of sunscreens – physical sunscreen and mineral sunscreen. Physical sunscreens contain mineral-based UV filters like zinc oxide and titanium dioxide that aid in reflecting the harmful UV rays.
- Chemical sunscreens contain ingredients like avobenzone and octinoxate and benefit the skin by absorbing UV rays, converting them into heat, and then releasing them from the body.
- For optimal protection, apply sunscreen 15 minutes prior to getting any sun exposure. For best results, reapply every two hours and immediately after excessive sweating and swimming.
- Remember, no sunscreen provides thorough protection from sunrays-induced damage. Hence, apart from choosing the right sunscreen, you must follow other protective measures like wearing sunglasses, hats, and long-sleeve shirts and standing under shades during peak hours.
