Anyone know how to use a Dermapen properly?

[Deleted member 2527]

Everyone says just use a dermapen/dermaroller bro but never go into details about the use
Some Qs I have:

1. Should you apply the hyalauronic acid/Vit C serum before Dermapen or after?

2. How long should you dermapen the whole face for... 1 minute? 10 minutes?

3. Is it dangerous to stay in one spot too long and are there areas of the face you should avoid

4. If you have thick skin what mm should you use. I barely felt anything at 1mm.

5. Should you press the pen into your skin or just lightly brush it over the surface level.

1 Apply products after dermapen always

2 Just press it, then move slightly to the side press again, keep doing until u reach everything

3 One Press in one spot is enough

4 Make it bleed

5 Press
