Final answer:
The layer of the skin where Malassezia furfur remains confined to is the stratum corneum.
Step-by-step explanation:
The layer of the skin where Malassezia furfur remains confined to is the stratum corneum. The stratum corneum is the most superficial layer of the epidermis, consisting of dead cells that shed periodically and provide protection against microbial penetration and dehydration of underlying tissues. Malassezia furfur is a type of yeast that is commonly found on the skin and is associated with conditions such as dandruff and pityriasis versicolor.
