What are some pros and cons of Derma Roller, according to customer reviews?

According to consumer reviews, the Derma Roller helps reduce shallow scars and facial lines for some users, but it is uncomfortable and does not produce adequate results for everyone. The Derma Roller creates tiny punctures in the skin that stimulate collagen and elastin production.

The tiny wounds produced by rolling the Derma Roller across the skin cause the skin to plump and fill in laugh lines, reduce the appearance of stretch marks, minimize superficial acne scars and aid the penetration of skin creams and serums. However, the procedure can be painful and cause skin irritation, and it has proven ineffective for a number of users.
