Dermatology Questions? Ask an Online Dermatologist.
Hello from JustAnswer.
There has been no action taken on this question in the Dermatology category, so it was opened in the Medical category. It is likely that no Dermatologist responded to this question because it cannot be said that cryotherapy does not damage skin. Complications to cryotherapy certainly can be said to be rare, but there is a rare risk of loss of hair, scarring, keloid formation, changes in pigmentation, or loss of sensation. The risk of these complications can be significantly lessened by only using short application times, but no doctor will be able to write a letter saying that cryotherapy will never damage skin.
You may be better able to argue your position if you were to ask a local Dermatologist to observe you in performing cryotherapy, and then that doctor could attest to the use of proper technique that will minimize the risk of complications.
