Can using a dermaroller and Retin A actually cause a depression in the skin?

Home rolling with a 2mm roller is very aggressive. A
.3mm home roller is best to use at home once the stronger 2mm in office
treatment has been performed. Retin A
should not be used immediately after a 2mm roller. This may cause more damage to the skin than
good. Retin A is a great topical cream
and yes the peeling is normal for the first 2-4 weeks after using but waiting
to use it after you’ve rolled is a much better option. It is important you consult with a
professional before and during your treatments.

Needles longer than 1.5 mm should not be used on the face as there are reports of scarring from this treatment, especially along the cheekbone. Also, rollers such as the Dermaroller create a more erratic
pattern of "tears" through the skin rather than the clean, more
evenly distributed punctures seen with motorized micro-needling machines. Rather than using Retin-A after your treatment, we combine motorized micro-needling with application of human growth factor serums. In my office we have found the RejuvaStamp micro-needling machine to be the
best of the motorized machines. We are also using the Rejuva Skin Care system
which combines motorized micro-needling with RejuvaCells human growth factor
serum made from human stem cells to give the best results.
