Final answer:
The stratum corneum is the layer of skin that can be softened using a hot towel to remove dead skin blemishes.
Step-by-step explanation:
The layer of skin that can be softened by using a hot towel to remove dead skin blemishes is the stratum corneum, which is the most superficial layer of the epidermis.
The stratum corneum primarily consists of dead skin cells that provide a barrier against microbial penetration and dehydration. Softening this layer with a hot towel can help remove dead skin cells and blemishes more effectively.
