What is Micro Needling?
Micro-needling is a skin rejuvenation procedure that helps minimize the signs of aging. The micro-needling device causes controlled micro-injuries that stimulate the body’s natural wound healing process. The micro-injuries trigger the release of cytokines and growth factors that lead to remodeling of collagen and elastin.
What are the benefits of micro-needling?
Helps reduce the signs of aging, improve the appearance of acne scars and rejuvenate aging skin. In one study of 60 patients with acne scarring, three micro-needling treatments resulted in a 31 percent improvement in skin texture, with no discoloration of the skin. Micro-needling was effective for all skin types.
Is appropriate for all skin types. The micro-needling device creates hundreds of tiny micro-channels in the skin with minimal damage to the epidermis. The procedure disrupts the junctions between the skin cells, temporarily disrupting the skin’s barrier function. This brief, mechanical disruption does not cause the melanocytes (pigment-producing cells) in the epidermis to react by increasing pigment production and darkening the skin in a process called hyperpigmentation. Therefore, micro needling can be used on all skin types, including darker skin that is more susceptible to hyperpigmentation.
Does it hurt?
A topical anesthetic is typically applied prior to a micro needling procedure. This allows for a comfortable experience for most people. Generally, patients report feeling just the slight vibration of the tool during the procedure. In one study of micro-needling used to treat acne scars, the patients’ average pain rating was only 1.08 out of 10. For most people, that’s probably less painful than having your eyebrows waxed.
Is there downtime?
The total healing time depends on each individual. Most patients have some slight swelling and redness/pinkness (like a mild to moderate sunburn) for two to four days following the micro-needling procedure. Some people may see their skin return to normal in about 24 hours.
