Ay, congratulations sa pregnancy! Honestly, most of us use regular sunscreen during pregnancy kasi kailangan talaga lalo na ngayon with hormonal changes na prone ka sa melasma, pero better check with your OB muna about Olay Natural Aura specifically, basta tingnan mo yung ingredients at walang retinol or harsh actives, usually okay lang. A few of my mum friends just played it safe and switched to pregnancy-safe brands like Mama's Choice Face Moisturiser na safe talaga para sa preggy and breastfeeding, pero hindi ko kailanman ma-pressure sarili ko to use specific brand kung may gumagana na. Best approach talaga is just confirm with your doctor para peace of mind mo lang, girl!
