Just come back from 2 weeks in the Caribbean
10 weeks post op when I went.
I used a thick factor 50 baby stick sunblock for my scars, that lasted all day even after swimming and sunbathing – it was still on my scars when I took my bikini off at the end of the day.
I used factor 50 on my chest for the first week, then factor 30 (and I’m dark skinned!) but didn’t burn my boobs once – which I thought may happen because of the stretched skin.
Lol one thing I did discover……implants hold the heat!
