Need Help Following Accidental Applicational of TCA for Warts on Skin on Neck and Face

RE - "my wife has tried wartner gel pen for application to two warts one on neck and one on face but didn't know it was very powerful, some has spread to the surrounding area of skin and caused brown discoloration. not sure of the conc of the acid (TCA) but worried about damage to her skin. i am concerned they are selling such potent acid freely. can she put some baking soda solution on it temporarily or hydrocortisone cream? will the skin recover as she has only put a small single amount? thx"

Sorry for your / her predicament. If there is a lesson to be learned from this situation is that chemical peels should not be a do it yourself project.

Without a photograph it is impossible to begin to advise you. Is it a deep burn or a mere increased pigmentation in reaction to the acid injury? Whatever you do, please, stop this self treatment. Pick a well trained Dermatologist and have him/her advise you on how to best extricate your wife from this condition before you worsen it.

TCA peeling can burn very deep depending on the concentration and the number of layers it is applied.

It should be used by the DOCTOR only who has knowledge of skin types and color and it's uses. It is not used for warts?????

Now you describe hyperpigmentation post inflamatory. Post inflamatory hyperpigmentation can be treated, but it has to be done by a doctor. It is a long term treatment. and may require several modalities of treatment, from skin care , bleaching peels, and laser
