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.
