Ah mama, honestly I just used regular sunscreen during my pregnancy kasi worried ako sa chemicals, a few of us moms just went with mineral sunscreen (zinc oxide or titanium dioxide) to be safe, and that seemed to work fine! Best talaga to double-check with your OB what they recommend for your skin type, pero most doctors say the important thing is protecting yourself from the sun rather than worrying too much about the product itself, mas risky ang sun damage kaysa gentle sunscreen, diba?
