Sunscreen math at 7:45 a.m

Tried teaching the two-finger rule with SPF 50 in exam room 3 before first clinic, and my teen fired back that his foundation is SPF 15 like it’s a legal shield against UVA. What’s your funniest, still-kind line that lands the broad-spectrum and reapply-every-2-hours lesson without me sounding like the moisturizer police?

I keep a clear SPF 50 stick and tell them “foundation is a hoodie, not armor,” swipe two finger-length lines on their hand, then let them apply it themselves. We set a phone alert for lunch to reapply, and if makeup’s the hill, I offer an SPF setting spray for touch-ups. If they roll their eyes, I pull up the AAD how-to and let the pictures talk: https://www.aad.org/public/everyday-care/sun-protection/sunscreen/how-to-apply-sunscreen.

At 7:45 a.m. I do a 10‑second demo: swipe SPF 50 on one cheekbone, mist a little water, then say, “see how this beads up, while foundation drinks it?” and follow with, “makeup SPF is the side salad, not the meal — one real broad‑spectrum layer, then reapply every 2 hours.” If they hate lotion, a mineral powder brush for lunch is my compromise — what’s your move in exam room 3 with the SPF‑15 loyalists?

At 7:45 I say, ‘makeup’s base coat; sunscreen’s top coat — every 2 hours,’ then hand a powder brush.
