What is Microneedling?
Skin needling, or more commonly called microneedling therapy, is a minimally invasive skin-rejuvenation procedure that involves using fine needles to penetrate the skin with minimal discomfort. The needles are used to create a puncture that triggers the formation in the dermis (the inner layer of the skin), of new collagen and growth factors. Through this process there is improvement in skin texture and firmness, a reduction in wrinkling, a reduction in scars and pore size. Moreover, microneedling can even improve long standing stretch marks. Finally, the process can also be used to improve hair loss on the scalp in both men and women by stimulating the hair follicles that have become dormant.
Microneedling has proven to be a fairly simple and fast method for safely treating wrinkles, scars, stretch marks and hair loss. The advantage of microneedling is that the outer layer of the skin, the epidermis, remains intact, and thus the healing from the procedure is fast, and as such, there is minimal down time. The process is performed with a topical anesthetic on the skin and typically takes about 15 – 20 minutes to treat and given area. The microneedling procedure can be repeated safely to further improve the effects.
The number of needling sessions depends on the individual skin condition. Three or four treatments may be recommended for mild to moderate acne scarring, whereas deeper scars and stretch marks may require upward of five treatments. An interval of 4 to 6 weeks between treatments is typically recommended. Many practitioners are also doing maintenance treatments at intervals of 6 to 12 months.
Platelet rich plasma, also known as PRP, will also significantly help the results of the needling session and can decrease the number of treatments. The PRP is applied to the skin while the microneedling is being performed. The PRP has additional growth factors that augment the result.
