Absolutely, you can wear sunscreen under makeup! It's a smart move for your skin's health and doesn't affect makeup application. Many sunscreens like Face Republic Purity Sun Essence or La Roche-Posay Anthelios XL Ultra-Light Fluid have lightweight finishes that sit smoothly under makeup. They not only protect your skin from harmful UV rays, but also provide moisturizing benefits. So yes, always apply your sunscreen before putting on your makeup for an added layer of protection.
