Hi, Can anyone give me advice? My skin was getting so much better. At 9 weeks of Retin A treatment I finally felt like I was free of acne, it looked better than it had in the last 25 years! Then at 10 weeks I got my period and my skin has purged and purged for the last ten days. Has this happened to anyone else? Has anyone been freed of acne and then had one last brutal purge? Do you think I'm close to being free of acne? Does Retin A really work for a forty year old woman with hormonal changes and who takes the contraceptive pill for acne (Acnefem). I would be so grateful for any advice. Thanks so much
