Clinical Trial Summary

The use of topical retinoids is a mainstay and basis of early acne treatment to prevent the progression to inflammatory lesions. Post oral isotretinoin, it is not uncommon for non-inflammatory papules and comedones to recur. However, there has been no formal study to look at the prevention of recurrence of these acne lesions post isotretinoin in a long term basis. This may enhance the therapeutic options for post isotretinoin patients in order to prevent recurrence of their disease.

Hypothesis Tretinoin microsphere 0.04% will prevent recurrence of acne lesions.
