Aw mama, honestly di ko na ginagamit whitening products since nag-breastfeed ako, better safe than sorry kasi hindi pa fully sure kung ano ang makaka-absorb sa baby through milk, you know? A few of us sa mom group namin pina-pause lang muna natin yan at nag-focus sa basic moisturizing at sunscreen instead, tapos once na-wean na namin, dun na nag-start ulit. Since kayo ay first-time mom pa lang at 3 months palang, better to ask your OB muna kung ano talaga okay gamitin while breastfeeding, baka may specific brands or ingredients na safe, so get peace of mind from doc mo directly.
