I have a perscription of Ziana gel. It's a combination of 1% clindamyacin and .25% tretinoin(basically topical accutane). I am using it for chest and shoulder acne. Just had a really solid bench session, but dont want to negate my workout. I know isotretinoin, or accutane can have an affect on joints, muscles, etc. Anyone think there is a risk of the gel affecting muscle tissue post workout and applying after a shower?
