Final answer:
A TCA peel resulting in a full frost indicates that the peel has reached the stratum corneum, the most superficial layer of the epidermis.
Step-by-step explanation:
When a TCA peel results in a full frost, it means that the peel has penetrated the stratum corneum, which is the most superficial layer of the epidermis. A TCA peel resulting in a full frost indicates that the peel has reached the stratum corneum, the most superficial layer of the epidermis. The stratum corneum is composed of dry, dead skin cells that provide protection against the penetration of microbes and dehydration of underlying tissues.
A TCA peel resulting in a full frost indicates that the peel has reached the stratum corneum, the most superficial layer of the epidermis. When this layer is reached, it indicates that the TCA peel has effectively exfoliated the outermost layer of the skin.
