Skin Creams while Brestfeeding

I am currently breastfeeding and have a few questions about skin creams..
I have dark spots on my legs and arms. I got them when I was still pregnant.
It's been months now and the spots did not disappear. These spots look like bruises..
I acquired some skin creams but don't now if these are safe when breastfeeding..

Here are the list of creams I want to inquire:
1. Green Peeling Oil contains glycolic acid, lactic acid,malic acid, salic acid, salicylic acid, citic acid
2. Arbutin Cream 3%
3. Glycolic Cream 10%
4. Medicated Astringent contains Epilobium Angustifolium extract, Arbutin, Tocopheryl acetate (vitamin E)

Hope you can help me!

The only one listed  that isn't recommended is the Arbutin or any other hydroquinone derivative. The benefit does not outweigh the potential risk and therefore, it is recommended to wait until weaning to use this type of medication.
