Any Estheticians here? :)

I used to be pretty aggressive with peels, BHA, AHAs but ive stopped using any chemicals on my face during pregnancy. Im wondering if i can safely use any of those things again while breastfeeding? I love using 'Paulas choice' exfoliating BHAs they make a huge difference in my skin. I guess my question is, r there any Estheticians here that can tell me what i can do to clean up my face after pregnancy while breastfeeding?
