I'm still breastfeeding and started a hydroquinone (12%) treatment a few days ago, for my melasma on my forehead. This morning I read that hydroquinone should be avoided while breastfeeding and now I'm worried. Is that correct and I should stop immediately, or is it ok while breastfeeding? Do I have to worry about my baby because I breastfeed these past days, while using HQ? Thanks.
