Will Infini RF cause sun sensitivity? Should I stop taking antidepressants beforehand that cause photosensitivity?

there is no reason to stop any medications before intensif. this is not a laser, this is RF which goes deeper and doesnt cause much resurfacing.  plus the treamtent itself doest cause photosensitivity.  Combine with sculptra and PRP for best outcomes.  Best, Dr. Emer.

There is no need to stop your medications. I would only recommend you stop most blood thinner medication such as aspirin and ibuprofen for these may cause more bruising from treatment. That said, your skin will be more sensitive to sun damage immediately after Infini treatment so please use proper precautions when going under the sun like using a high physical SPF sun block or avoiding the sun all together the week after your treatment when healing. 

The medications you will have to stop or hold are any blood thinners you might be taking.  You will need to discuss this with the physician doing the INFINI. Also, INFINI is not a laser; it works within the dermis and not the superficial skin layer.  I hope this helps.
