Hello roy337,

The verruca-freeze is an alternative to liquid nitrogen and not exactly liquid nitrogen. It is used for 21 benign conditions and has a temperature of -70 degree Celsius.On the other hand liquid nitrogen has a temperature of -196 degree Celsius.

We in modern medicine don't use freeze methods for treating flat moles (junctional moles).The best method would be a laser therapy .

Now in your case there has been an injury to the skin leading to post inflammatory hyperpigmentation (PIH).Healing of skin depends upon how deep the injury is .If it is very deep in dermis then it may lead to a permanent mark or else it would gradually fade away.

Healing also depends upon which area of the body is involved & your skin type. Face has the best healing property because of its good vascularity .Chest would come the next.

It would be difficult to say at this moment that the scarring is permanent or not.

Usually such type of injury take months to heal. It would be a slow process. A mild steroid applied locally for a week may speed up the process. This would work like a anti-inflammatory agent. Later on you can mix hydroquinone cream to it. You can take a local dermatologist’s opinion on using these creams. The results would only depend upon how deep the pigmentation is.

Hope that this information helps and hope that you will get better soon.
