Dear teens777:There are many different topicals that can be used for Microneedling, and some patients have the procedure without any prior topical numbing. Allergy to topical is very rare, whereas done other agents such as tetracaine and benzocaine are more likely to cause reactions. I do believe it is possible to find a way you can have this treatment with comfort, and also would recommend you have PRP with the Microneedling.All the best,Dr. Clark
Hi teens777. It is difficult to say from your description of what happened. Some topical numbing creams do normally cause tingling...Notwithstanding, microneedling with radiofrequency, as found in the "Profound" technology is a good treatment for skin tightening and increasing dermal volume, both of which will improve acne scars. We perform this treatment after injecting local anesthesia, not topical.
