Check, I said every other day and again no wounding light firm pressure. I guess you right in some way, I just ordered new derma rollers as you suppose to change them and mine are some bent over time! I guess il switch to 0.5mm ever other day and 1mm once per week, although I have used 1mm for years without any issues every other day.
This is what online states:
A 0.2mm or 0.3mm derma roller can be used with minoxidil/hair loss treatment every day or every other day (start by using every other day and see how your skin reacts to the minoxidil/hair loss treatment; if you do not experience any side effects you can increase to using every day).
A 0.5mm derma roller can be used with or without minoxidil/hair loss treatment 2-3 times a week.
A 1.0mm derma roller used without minoxidil/hair loss treatment can be used once a week to once a fortnight.
