What is the ruling on using exfoliating cream to remove dead cells that cause pimples and black spots, without the intention of lightening the skin or changing the color of creation?

The basic principle regarding the use of paints and dyes is permissibility unless there is evidence to the contrary. Therefore, it is permissible to use this paint to remove dead cells and pimples due to the benefit it provides. It is prohibited if its harm is proven. A temporary change in skin color is not harmful, as the prohibited alteration of God's creation is specific to permanent changes. This paint falls under the category of treatment or removing blemishes, and is not an alteration of God's creation.
