Bleeding with Microneedling

When you bleed with microneedling, it shows you are at the correct depth. From a numbers perspective, I recommend a 1.25 mm depth. I particularly like the “Dr Pen” device because you can hold it over each area and deliver an effective injury to induce the healing cascade. Once per week is adequate; more frequent use is unnecessary. The photograph shows that you are using it where you want your hairline to return. I can see that clearly by the bleeding that shows in the photo.
