Hi Dr. Rassman, great blog.
I was wondering, whats your view on the effects of Minoxidil on collagen?
Iv heard a few reports of people experiencing bad skin and increased wrinkles on the face when using Rogain, also there is a paper out which shows Minoxidil does inhibit collagen production.
I personally do not believe applying a topical medication on your scalp will cause wrinkles on the face, but we’ve written about this before here. What paper are you referring to? The one I’m aware of is relating to rats, not humans.
If you are concerned about such side effects, speak to your doctor and know that you have a choice to use or not use the product.
