The results for stretch marks, acne scars and trauma scars are permanent. For skin rejuvenation, how long the results last will depend on the rate at which your skin ages – every person responds differently. The Dermaroller acts by stimulating your own collagen but this will diminish again as you age.

That being said, results are generally long-lasting – from six months up to two years – and we usually recommend annual or bi-annual ‘top-up’ treatments.
