Hi Kb, thank you for the question.
The Dermaroller is a device that allows needles that are 1.5mm long to pierce the skin as it is rolled over the surface of the skin. The procedure is painful and therefore requires a topical anesthetic cream to be applied at least 1 hour prior to the procedure. Immediately after the procedure the skin appears inflamed and may be erythematous (red) and swollen, and this may last for 2 to 3 days. Various studies have shown an improvement in the appearance of hyperpigmentation, texture, acne scars, and stretch marks. These changes are predominantly due to the increased production of collagen and elastin. 1 to 3 treatment sessions may be required and an at-home roller should be used for maintenance. Topical products need to be applied to increase the effect and results.
