I was hesitant that this would hurt to use this Derma Roller SGF + FREE Travel Kit-Titanium Micro Needle Rollers, but did not at all! I have been trying to use this regularly and believe I am starting to see a difference in stretch mark areas and scars! Treatments are usually frightfully expensive, often invasive and have varying degrees of success.
This Derma Roller SGF + FREE Travel Kit-Titanium Micro Needle Rollers device is great, it gets results but I would suggest to start off with 0.5 mm then jump into this one, you know to get you accustomed to piercing your skin with small needles, maybe my skin is too sensitive, other friends of mine have this same dermaroller and they have no complaints, so go ahead and buy it but make sure is the one with titanium needles they don't give or breakout allergies.
