Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain the symptoms of redness, burning sensation and itchiness after using Melas ointment is not just skin exfoliation but it seems to be a side effect of using the ointment and you should immediately stop using the ointment and in case if still there is itching r burning you can take anti allergics like Allegra or Levocetrizine..
You can do cool compresses over the face and do cold water splashes..
Once the symptoms resolve you can start washing your face with
Salicylic acid and
glycolic acid containing facewash..
You can start applying creams containing
Kojic acid, glycolic acid and arbutin..
Apply
Vitamin E gel at night..
Exfoliate your skin weekly with a gentle face scrub..
You can also go for photofacial, galvanic facial or
microdermabrasion.
Hope this information helps..
Thanks and regards.
