Applying sunscreen before applying makeup
You shouldn’t apply sunscreen before foundation, says Los Angeles dermatologist Jessica Wu, MD. “If you use sunscreen first, and then you use an anti-aging product and then a moisturizer, and then makeup, you’re disturbing that sunscreen film,” she adds. Applying other products on top of sunscreen removes some of the SPF, leading to uneven coverage. Instead, apply a thin layer of sunscreen with at least SPF 30 to your skin after you finish applying makeup.
Depending on your makeup’s SPF for sun protection
A tinted moisturizer or foundation with SPF is better than one that doesn’t offer sun protection, but most people don’t apply enough SPF-containing makeup to adequately protect themselves from harmful UV rays, according to Health magazine, and you often miss your ears and neck. Also, your makeup’s SPF may only protect you from UVB rays and not UVA rays (both increase your skin cancer risk and aging). Instead, apply both your SPF-containing cosmetic products and a separate broad-spectrum sunscreen that protects against both UVA and UVB rays. Make sure you avoid these other awful beauty tips that everyone should ignore.
