How much percentage of improvement can I expect from Derma Rolling for my acne scars on cheeks?

In the US, legally we have to advise you to goto 0.25mm at home. In the office, we can go to 1.75-2.0 mm without problem. Like Dr Schwartz I do not like rolling on the neck- too much ripping and tearing of the skin, thus leaving marks. Best use a stamping device. See the attached video for how ...

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...

Thanks for the clarification of the FDA ruling Dr Rapaport. We can only recommend you use 0.25mm in the US, however in Australia, I get my patients to perform up to 0.5mm in SELECT areas. Anything above 0.5 mm, performed correctly will not only be painful, but will bleed. This may cause ...

How effective rollers are will be determined by your end goal, severity of your loss of collagen, technique, depth of rolling, and frequency. Derma Rollers do work, however they are almost 2 decade old, stamping technology with growth factors is the next step, and then energy based needling with...

I ask my patients to use tretinoin after skin rolling- micro needling, however the rate limiting factor is skin irritation. On this basis I get them to use Vitamin A 2-4 days after. When one needles to create channels, in theory we would like penetration of the vitamin A - tretinoin-...

I personally would recommend a 0,5 mm roller for home use. Anything approaching 1 mm will require numbing cream and antibiotics afterwards as you will bleed. I like a once to twice a month regime for my patients to do 'home work' in between energy based micro needling devices. See more...
