Microneedling is a very common practice in dermatology to treat acne scars, severe eye puffiness, and wrinkles, sun damage on the skin.
This damage resulting from too intense sun exposure is characterized by visible discoloration, wrinkles, and capillaries.
To know if the micro-needling is indeed the trigger of the problem, you must be sure that these capillaries were not already visible before the intervention.
If it wasn't, chances are it's just the ongoing healing process.
Indeed, in this period, you can notice a proliferation of capillaries which is only the organism's response to microneedling.
