Hi and welcome to HCM. thanks for the query.
1st degree burns heal with no scarring so you dont have to be worried. You just need to be patient.There is no some specific way to speed up healing process and no creams are necessary. Just keep this area clean and dry,cover it with sterile gauze in next several days. redness
should subside in 4-5 days. Dont do such things in future since more serious consequances may happen. Wish you good health. Regards
