"i have been using this for 1 week with an antibiotic called solodyn (minocycline). i have light acne but my biggest problem was painful hormonal cysts on my chin and this did not leave me dry like retin-a did. i had noticeable results in just 1 week! with any skin issue i know that results don&#039;t happen overnight but i am so happy with this product that i had to review it!"
