Retin-A for discoloration - no results after 7 weeks?

Hi Laurajayne,

Thank you for this question. Tretinoin is an excellent treatment for both of the conditions you are suffering from. With regards to acne, tretinoin is particularly effective for the comedonal type ("black heads") of acne and I typically tell patients results will not be noticeable for up to three months with appropriate use. It is particularly important to review with your dermatologist how you are applying the medication and that you are using it at night (it is photo-labile -- sun breaks down the medication). For sun/UV related pigmentation on the face, I would recommend using tretinoin in conjunction with skin lightening agent (such as hydroquinone). Results should be noticeable with dual therapy after approximately four months. It is important to have any dark spots on your face examined by a dermatologist to make sure they are not pre-malignant or malignant.
