Hi, I am a Pakistani (means Darker Skin Tone) and have released a wonderful son 7 months ago. All well and good but that has also left its mark. I had very bad stretch marks all over her belly. So I decided to English youtube videos and positivern revisions to order this product. People I really thought I would this strips never let go. Today I have for the first time using the Dermaroller needles 1200 and I can only say I am thrilled. I did not expect that I will have so quickly notice a change. The stretch marks have become brighter and mainly declined -> for an application. After the application I used Palmers a coconut cream. I would highly recommend them. What can I say more will I bought the Dermaroller the needles in 1mm length. It does not hurt ... only slightly uncomfortable. People to attacks. I have this system now also be found on my face ... I acne on face and features will be slightly lighter. Sorry for the long Rezision .. But I am just thrilled ..
