Skin care while breastfeeding

Ok mamas,

So I am wanting to buy some new skin care products but everything I have looked into using has a warning to not use if pregnant or lactating! I previously used rodan and fields and was looking to get something different. I was really wanting to try skinmedica as it is dermotologist grade strength but it has a warning label that it is not tested on pregnant or breastfeeding women. What do you all use for skin care? Looking to treat acne, dark spots and anti aging! Thanks in advance!
