I have been getting a lot of questions how long should derma rolling session last? You should never derma roll your face longer than 10 minutes including the neck, 10 minutes is enough for your skin to produce collagen and elastin. By over doing, you can cause additional trauma to the skin, which may lead to premature aging.
I would like to share with you a really important information how often to replace and to use Dermaroller.
It is important to use each needle size accordingly to the table suggested in the link below and the number of uses should NEVER be more than 10 times.
