Does the order of sunscreen and moisturizer matter?

Yes, sunscreen should be applied after moisturizer, as the last step before makeup. This ensures the sunscreen filter layer sits at the top where it can interact with UV rays as they hit the skin surface. Applying moisturizer over sunscreen can dilute the filter concentration and disrupt the protective film, reducing SPF efficacy. Wait one to two minutes after moisturizer before applying sunscreen for best results.
