Non-Edible Skin Products Containing Haram Animals Ingredients
I improved upon my opinion. If the external use of a thing does not become a part of our body, then it is halal like the use of the skin of a dead animal. However, in the case of cream and lotion or oil, they become part of our body. The moisture they have entered into the skin to make it better. However, shampoo can be exempted but we know that pores in the skin of the head allow a liquid or oil which stays for some time to be absorbed into the body. This is my opinion so far.
