Hi all, I just want to jump up and down. I adore you all and this site. I am a skin care junkie. But, this is THE BEST for information. I just ordered Retin a micro 0.01% from alldaychemist.com. The prices are teriffic. Eventually I will order the glycolic peel from makeup artists.com. The only question, I have read other posts and they saw different strenghts for RA on the ADC website, I only saw RA micro. Can anyone tell me the difference in RA and the micro???
