I have been receiving treatment consistently for 6 months using an app event dedicated to dermatology procedures. In fact, porous scars (fine scars) do not improve in a short period of time. However, when I compare it to the photo from 6 months ago, I can see that the scars have filled up a lot. Also, there is a dermatologist who I regularly visit for acne extrusion, and when he saw this person, he said that it had improved a lot.
