I have clumping and separation issues when I apply Coppertone sunscreen under my makeup. What am I doing wrong?

• Choose the appropriate sunscreen. To minimize interference with makeup, choose lightweight, oil-free formulas labeled "oil-free" or "non-comedogenic". Mineral sunscreens with zinc oxide or titanium dioxide may also perform better under makeup than some chemical sunscreens.

• Ensure proper application. Apply sunscreen before makeup and let it dry for 15-20 minutes. This stops mixing and pilling. To create a smooth surface for makeup, apply a thin layer of sunscreen to your skin and gently pat it in rather than rubbing it.

• Consider your makeup options as well. Experiment with a mattifying primer after sunscreen to create a smooth canvas for makeup application while minimizing separation. Choose oil-free makeup products to reduce the likelihood of sunscreen and makeup interaction resulting in separation.
