SkinPen medical needling creates mini channels in the skin which enable us to reach the into the dermis layer of the skin, this allows us to stimulate cell renewal. The increased blood flow to the area brings oxygen and nutrients to the area; this encourages the production of collagen, elastin and hyaluronic acid which strengthens the skin, and hydrates to plump the skin. 
The collagen produced tightens the skin and helps to minimise the appearance of scarring and pigmentation.
SkinPen was launched in the UK in 2017 and is medically certified both in the UK and the USA.  It is the only FDA approved needling treatment and is clinically backed for both safety and results.
