It is important to clear up those misleading myths, and also recognize the best practices for using sunscreen to ensure optimal fun in the sun.

Debunking sunscreen-related myths
Three persistent incorrect ideas regarding sunscreen use are:
- High SPF is better by default: Sun protection factor (SPF) is the measurement of a sunscreen's effectiveness at repelling the sun's ultraviolet-A and -B rays (UVA and UVB). But high SPF only matters up to a point. According to the Environmental Working Group (EWG), a conservation and environmentalism organization, using super-high SPF sunscreen while still staying out in the sun too long remains dangerous. Don't go lower than 15 or higher than 50+.
- Vitamin A is OK for sunscreen: As of 2017, the EWG noted that 14% of all sunscreens contain Vitamin A, which studies have shown can weaken skin, making it more susceptible to lesions. Simply checking the ingredients of any sunscreen before use can help to avoid vitamin A, retinol, and retinyl palmitate, advised EWG.
- You only need to apply once: The American Academy of Dermatology (AAD) stated that sunscreen should be reapplied every two hours and after swimming.
