Hi, thanks for your query.
It seems that you may have developed contact
irritant dermatitis due to the contents of the new face wash , so avoid using the face wash again.
To treat it you may do as follows:
Wash your face with cool water.
Use a mild cleansing agent.
Don't rub it with a towel, just pat it dry.
Apply a mild
steroid cream like
hydrocortisone twice a day till the
redness comes down. It may take a week or so.
Avoid sun exposure as much as possible and use a broad spectrum sunscreen during the day even if you are indoors.
You may take an anti histaminic if itching is present . Avoid scratching or touching the blotchy area.
If the condition worsens further you may
consult a dermatologist nearby.
Hope this solves your query.
Wish you a speedy recovery.
