"i have tried absolutely everything to get rid of my acne.  i&#039;ve been seeing a dermatologist since my early teen years.  i have also done microdermabrasions and chemical peels.  claravis really worked for me.  i have my blood work done once a month.  i have not had any serious side effects, just chapped lips.  i would recommend claravis to anyone who struggles with persistent acne."
