Hi thanks or your question
You had developed allergic reaction
to the local anaesthetic
ointment applied to your skin, during Radio frequency treatment.
Anaesthetist usually, apply lidocaine
ointment to skin to produce local anaesthesia for various procedures.
Lidocaine ointment can produce local allergic reaction.
The Doctor has prescribed you Demelan ointment, which contain Glycolic acid
, Kolic acid and Arbutin
Demelan cream increases cell turnover and helps to diminish fine lines and gives healthier and smooth skin texture.
Doctor has given you right treatment.
Additionally, you can use local steroid antibiotic combined cream.
