Hi All,

I am new here and need some help, I have been on green cream for the last 3 years and currently use level 9 twice a day. I would like to try to incorporate a perscription vit. a product into my routine. I am looking to purchase from inhouse pharmacy and notice they only carry retin-a, retino-a and differin. Which one of these would I start with and at what strength? I would appreciate any insight on these products and any help that you all can give me.

Thanks,
Lin
