You do not need copper peptides but you do need Infadolan. You should follow more or less the routine that is in the link I have given you. That includes Tretinoin and Infadolan.
OwnDoc dermarollers are very good. In fact, OwnDoc rollers have better needles, since for the past 18 months we've occasionally seen reports of bent needle tips in new Dr. Rollers. That's why we're phasing them out. The difference between Dr. Roller and an Owndoc dermaroller is that Dr. Roller has a slightly more robust rolling mechanism but you have to replace your dermarollers when they get blunt so you cannot use the same dermarolling instrument for years anyway (if you use it frequently). The most important part of a roller is good quality needles and Owndoc dermarollers have good quality needles.
You can do all your stretch marks in one session (approx. every 4-6 weeks, depending how quickly your skin heals and how deep and densely you stamp) but only if you have time and energy to do them all thoroughly and densely.
Stamping will make the stretch marks temporarily more red but long term it helps fading the purple color of fresh stretch marks. Do a test patch first. Do not stamp all you stretch marks the first session.
I get emails such as:
I had red fresh stretch marks that i rolled once a month with the 1.5 mm dermaroll. Great improvment. The size is reduced by 50% and the redness turnes to a white" raised worms".
