To reapply sunscreen over makeup without ruining your look, start by blotting excess oil with a tissue or blotting paper. Then, use a lightweight SPF product and press it gently onto your skin using a damp sponge or clean fingertips. Avoid rubbing, as it can disturb your makeup. Alternatively, opt for SPF mists or sticks for quick and mess-free touch-ups. For bare skin, apply a generous amount of sunscreen and pat it until fully absorbed.
