Is "facial aging" from minoxidil real or is it just hype?

It's just hype. Some people are allergic to propylene glycerol. When that's the case, foam can be used. So
allergies might increase puffiness, but that's about it. I take very high dosages (30% cream/supplemented
with 5%). Nothing happened to my face. Everybody's different though.

Isn't minox said to inhibit collagen production or something ?
