what measurements will be correct for my scars , i need to eliminate or make these scars less noticeable before the start of September. so someone please help me
No one is debating microneedling. In Dr Lim's earlier videos. He states dermastamping causing microtears to the skin and thus is not a good idea. This recent video He call's it a "version 1 device". He also states dermastamping is a "version 2 device."
In the video one must use a dermaroller only once (disposable) , when dermarollers are far costlier than dermastamps.
The best solution is a automated machine like the derminator to do needling at multiple lengths for DIY, followed by a manual dermastamp.
Further the OP's scars in the picture will not be eliminated with dermastamping alone. As you can see he has rolling & boxcar scars.
