i think it is ok. because my derm office sells thie "obaji" prodcut thingy. and in prepaaratoin for the 'blue peel' people use AHA creams, Retin A and a 4% hydropquione bleaching cream * prescription strenght * i have read others using that skin care regimen too. you should be fine. but ask your derm who prescribed the retin a to find out if you can wear it at the same time. also u might want to check out obaji products online. i cant afford them either but somteimes i go there to see what the products are, im sure you can make your own routine just like it using diffrent products.
