For pigmentation, use our 0.025% Tretinoin cream and apply every second day (without dermarolling).
You should add a 1.5 mm dermastamp with 35 needles to your dermarolling (stamp just the scars).
Apply vit. C on the days that you do not apply Tretinoin. You can re-start a day after rolling/stamping but only if the skin is not "raw" from dermaneedling any more.
Apply vit. C for at least three consecutive days before stamping. You can either stop Tretinoin on these days or wait for vit. C to be absorbed and then apply Tretinoin.
If you get no improvement with your 1 mm dermaroller and a1.5 mm dermastamp in six months, add our suction pump and use it on your rolling type of acne scars. The rolling type of acne scars are often tethered to the underlying structures and that makes the scar depressed.
In the morning, apply a moisturizing cream of your choice.
If your post-acne pigmentation does not get better, start applying Tretinoin three times a week after rolling with a 0.5 mm dermaroller but not everybody can handle this because dermarolling greatly enhances the penetration of skin products and Tretinoin can be quite irritating.
