I would probably go for a serum rather than an oil since immediately after / during derma rolling there are those tiny punctures in your skin, which allows your skin to absorb the serum better. Go for something high in vitamin C, hyaluronic acid, etc.

im surprised no one has asked, why dermarolling and not dermastamping?

14 minutes ago, JesusChrist said:

Dermapen should be used, stamp and rollers became blunt after a while.

that's assuming you would use the same stamp and roller over and over again...

why would you assume that?

also, dermapen is the same as dermastamp except dermapen is smaller in diameter (covering less area)

dermapen also lacks manual control... in fact i bought a dermapen and tried using it but being that it's automated,the lack of control made me go back to dermastamp

Why would anyone buys dermaroller or stamp if they use it one time only? It will cost more thats why they re-use it.

I already said why, dermapen is hard to control and covers less area and i would never recommend dermaroller over dermastamp

what have you used? what is your experience?

--- as for cost, you can find a cheap dermapen like you can find a cheap dermastamp or you can find an expensive dermapen like you can find an expensive dermastamp..

cost is relative and fluctuates...
