My daughter is 7 years old. She has a small pimple like skin growth on her chin. We applied raw garlic paste over it for more than one hour. There is a swelling and pain. We removed garlic completely and washed. We apply aloe vera(raw) on the swelling now. The skin looks red and swelling remains. We continued aloe vera overnight. What is the correct treatment and how long will it take to heal perfectly or back to the normal skin? Please advise.
