In vanishing cream formulations, what role do glycerin or sorbitol primarily play?

Explanation:
Humectants are substances that attract water and help keep skin hydrated. Glycerin and sorbitol act mainly as humectants in vanishing cream formulations. They draw moisture from the environment and from deeper skin layers into the outer layer, reducing transepidermal water loss and giving the product a smooth, comfortable feel. This moisture retention also contributes to the “vanishing” sensation as the film dries and leaves only a light residue. They aren’t emulsifiers, which stabilize oil–water mixtures; they aren’t preservatives, which prevent microbial growth; and they don’t provide color.
