6 weeks post op Derma Stamping, I noticed white marks/scars on my face. Is this normal?

Whenever micro-needling of the skin is undertaken, it is very important that nothing is put on the skin that is not safe if it is delivered into or under the skin. This includes the Aloe Vera Gel that you have been applying. Micro-needling creates micro-channels in the skin which enhance
penetration of any topically applied serums and medications. It is only by using products that are tested to be safe for injection under the skin that you can be reassured that it would be very unlikely to have an adverse reaction.

In my office we use the ProCell Therapies system which combines
motorized micro-needling with concentrated human growth factor serums made from
human stem cells and we have been getting excellent results for facial skin
rejuvenation. We thus far have never had a problem with allergic reactions or causing additional scars.
