I applied Dettol on my face today around noon for about 5 minutes and it caused a burning sensation. After that, the area turned black and then red. I washed it with cold water and applied ice, then used Lacto Calamine lotion at 3 PM. Now there's a blackish mark on my skin. What should I do next to treat it?

Continue applying cold compresses: Cold water and ice can help reduce the burning sensation and inflammation.2. Lacto Calamine lotion: You're on the right track with Lacto Calamine lotion, which can help soothe and calm the skin.3. Topical antibiotic cream: Apply a topical antibiotic cream, such as Neosporin or Bacitracin, to prevent infection.4. Hydrocortisone cream: A mild steroid cream, such as hydrocortisone, can help reduce inflammation and itching.5.
