You may experience some dryness and peeling in the first 3-6 weeks of using your personalised prescription cream.  This is normal and nothing to worry about.  If you feel you are experiencing more extreme side effects, please do not hesitate to contact us.
“Purging” is a  rare side effect of personalised skincare.  Most commonly, perceived “purging” is an acne flare that would have happened anyway.
We generally recommend continuing use even if experiencing a “purge” unless your skin barrier is compromised.
