Should I stop using minoxidil if it causes light patches on skin? And are the patches permanent?

Question

I started using minoxidil along with biotin a month ago to stimulate my beard growth. There has been a good amount of growth during the period but my skin has started developing lighter patches. Should I stop the use of it or decrease the dosage?

It's difficult to make a determination of the cause of your skin color changes. As a dermatologist, I'd need to know more information including what type of minoxidil you are using.  Skin lightening can be caused by multiple factors that likely needs an in-person evaluation to make the appropriate diagnosis.  As examples, vitiligo, allergic contact dermatitis, pityriasis alba, post-inflammatory hypopigmentation, discoid lupus, and more can all cause skin lightening.

Hello and thank you for your question. I have not heard of Minoxidil causing light patches on skin.  I have heard of a modest skin irritation or redness but not light patches. You might want to check with your doctor. Best wishes.Dr. T
