I have fordyce spots on the shaft and foreskin of my penis. I have read online that tretinoin works in getting rid of fordyce spots. First off would it be better to use a cream or gel version? I was thinking the gel since I have found many testimonials that the cream leads to rashes and massive skin peeling. Secondly in addition to the first question: should I use the 0.05% strength gel, 0.10% gel, 0.025% cream, or 0.05% cream. Obviously mattering whether cream or gel is preferred. Thanks.
