Thanks for writing to us.
Verrucas or warts
in children usually resolve spontaneously in two years time. Treatment is required if the lesions are increasing in size or number.
Treatment can be offered in form of topical creams like tretinoin
or salicylic acid
. Definite treatment would be cautery of the lesions.
The treatment that you are following( creams and gel) may not help much. Zinc being an immunomodulator and immunity booster may be beneficial.
Hope that helped. Take care.
