Using undiluted dettol
lead to irritant dermatitis
at the area of application. Use a steroid
based cream over the area atleast twice in a day. it would take almost a week for your lesion to heal. You can use a properly processed aloe vera
gel available as over the counter product to soothe the burnt area, however do not use fresh aloe vera gel obtained directly from leaf as unprocessed aloe gel at times can cause an irritant reaction. Take care.
