hi..Thanks for your query I would like to mention here that its important to know that Acne can present in several forms. This includes whiteheads, blackheads, and red, inflammed patches of skin (such as cysts).In the course of evolution, you may have any or all of these.Sometimes ,over a period of time, even if you are under a specific for of therapy,one agent might not be enough to handle it completely.This is based on the various internal hormonal stimuli as well, which can change several times in a month or year. Although Evion is a good supplement,there may be a need of addition in oral /topical therapies. Eg: Oral antibiotics such as tetracycline, doxycycline, minocycline. Topical antibiotics such as clindamycin, erythromycin. Other needs may be benzoyl peroxide ,salicylic acid,topical azelaic acid. These can only be suggested when a dermatologist has actually seen the type of lesions you have. U definitely do not need to stop anything now, however please visits the doctor early so that there are no delays in the onset of more efficacious therapies. A clear skin essentially involves having extra acne/oiliness clear.U should also use an oil free gel based sunscreen to achieve a glowing skin. Hope this helps..take care!
