Do I Need To Reach Blood To Induce Collagen?

[Newday]

Hi Sarah,
I was wondering whether or not I need to Derma Stamp until I see blood come out of my skin on the face, in order to induce collagen production.  Can I just rough up the skin until it's really red but not till it bleeds to induce collagen? Or do I need to see blood for collagen to actual form?

Are there any cases where people had seen scar improvement without seeing blood?

I have very very shallow and minor acne scarring that are located in 2 small areas, on both sides of my nose. The look like pores that a bit enlarged but not a lot.

Thanks in advance!

Edit: To fix up the last sentence, I meant to say They look like pores that are a bit enlarged but not a lot.

Also to ask, would a 0.5mm derma stamp be enough for very very shallow indented scars?

You do not have to induce blood.

In order to induce collagen you have to reach the dermis part of the skin. A 0.5 mm needle size reaches the top of the dermis so for scars, use at least 1 mm dermastamp or longer.

This is a paragraph from our dermarolling instructions concerning enlarged pores:

Enlarged pores

Dermarolling works very effectively on acne scars but pores are not scars. Pores are ducts in the skin and their size is genetically determined. There is currently no method that can reliably and permanently make pores smaller. Very few of our customers managed to make their pores smaller through microneedling. You can try a regular 0.2 mm or a 0.5 dermaroller to thicken the epidermis or a 0.5 mm dermastamp. A thickened epidermis could make pores look smaller because the pore size is the smallest on the skin's surface and as you go deeper into the skin, the pore channel widens. Some of our customers improved their pore size with the single needle but always try just one pore to see if it is not making it worse. Do not expect results too soon.
