It seems as though dermarolling has help alot of people. However I'm here to warn to not mix Dermaroller with anything untested. Especially RU or CB03 or even minoxidil. Becasue it could have huge impact on your body. Since I started Derm Rolling in Dec, I had AWESOME result. My hairs stop falling off and seem like a lot less hair in showers, on the pillow. Or simply every morning when styling my hair. However I decided to start using RU in conjuctions and since then I had 3x Eyes infections. Two to my Left and now the 3rd on my right. I have never had this happen to me my entire life and is the first Time I have ever seen this. The doctor told me he have no idea what RU is and certianly to never touch it again. The first time it happend the condition was much worst, however yesterday was much less impact. However I have also stop rolling for last 4 weeks as I got really scared. All I can say is be very careful when doing home therapy such as this.
