i am getting the Infini treatment done for acne scarring. Do i need to discontinue tretinoin cream or doxycycline ahead of time?

Infini treatment, unlike laser or IPL, does not involve light; but rather microneedles which emit radiofrequency into the deeper skin layers.  While doxycycline should be discontinued prior to treatments that deliver certain wavelengths of light, there is no need to stop taking it before or after Infini.  Since post-treatment products that are used after Infini may increase the chance of a breakout, there is even more of a reason to continue taking the antibiotic. Regarding tretinoin (Retin-A and others), I recommend waiting until a few days after Infini treatment to resume applying, due to potential increased penetration and irritation.  Otherwise, I believe in topical retinoids for life (just not during pregnancy or lactation), which not only improves acne, but also helps to keep cells "acting young."  With Infini, you've chosen a state-of- the-art treatment for acne scars with virtually no side effects... and you should look forward to beautiful skin!

In our practice, we combine retinoids with Infini RF for better results.  Especially for someone wanting to improve their acne scars. We recommend a series of 5-6 for acne scarring.  I don't feel you need to stop your retinoid cream prior to your treatment.  It is always best to consult first with your treating provider if you are unsure.

If you have to ask this, I suggest you speaking to your physician or consider a different office. This should all be reviewed with you PRIOR to your treatment.  In my practice I do not stop any of these treatments.  You will need a series of microneedling/RF for acne scar improvement and often need it in combination with lasers, fillers/sculptra, and skin care.  Best, Dr. Emer.
