Skin Needling also known as Micro-needling uses tiny fine needles to prick the outer layers of the skin.
This stimulates the body to produce collagen to heal the micro-wounds caused by the needles. 

When the new collagen is produced, the skin becomes smoother & appears more youthful.
Micro-needling can even be used to improve the appearance of scarring, stretch marks & wrinkles. 

While you might find the idea of using needles a little scary, the procedure is very safe, quite painless & requires minimal downtime.
