Topical treatments while breastfeeding?

Pr

My son is a year old, & still nursing about 30-40% mostly at night. I have very bad acne & some acne scaring I’m trying to clear up but my esthetician won’t do any treatments on me until I am 100% done with breastfeeding? By treatments I’m meaning, chemical peels & using salicylic acid & bhas. I understand for the safety of my son but I’m just wondering if anyone has any advice. I do not want to stop breastfeeding, I wanted our journey to end naturally but I am also so eager to start treatments, I hate my acne & have lost my confidence. I know it’s something I want to start treating soon.
