I lurk around these forums often and have never created an account. It's like 3am and I decided to just do it.
I don't know if it's just hyper-pigmentation or some sort of scar? That was from cystic acne (curse dairy products)
The other side of my face I can tolerate for now but this is not cool.
I'm currently dermarolling with 0.5mm w/ vitamin c
Also, I press down on it and it instantly fades before appearing again. Does this mean anything?
Welcome to the community.
When you press down on your skin you push the blood out of that area causing the pinkish colour to fade and when the blood returns to the area the colour returns. Its normal. Push down on your finger nail and you will notice the same effect.
With regards to the dermaroller Ive read that using anything under 1mm is pretty pointless for scarring. 0.5mm would be used to only freshen the skin of someone who has no scarring at all. I would recommend buying anything from 1mm to 1.5mm to start seeing results.
With that said there is discussion that the roller causes trench like cuts as opposed to the collum cuts that you would like to have. Maybe look into the stamper. Also please allow ample time between rolling (4/6 weeks) for the skin to heal properly. Heres a little video to show what I mean.
Vitamin C is great for collagen production but as this is an acidic topical this may be contributing to the redness and you should look into taking this vitamin as a oral supplement of at least 1000mg vit c.
I would look into copper peptides as a new topical treatment.
