My skin purged like crazy for a week, I almost stop using it but my sister insisted that it will go away soon. And it did, after the purge, my skin looks like it just got upgrade. I have dry flaky skin, and I notice after more than a week, the flakes started to disappear, my blackheads are still there but I believe it will go away soon since I saw what happen to other area on my face after the purge.
