The use of papaya enzyme peels on sensitive skin is appropriate due to the gentle nature of the enzymes derived from the papaya fruit, specifically papain. This enzyme works by breaking down dead skin cells and promoting exfoliation without causing significant irritation, making it suitable for individuals with sensitive skin.

Pineapple enzyme peels, while also naturally derived, can sometimes be more irritating due to their higher acidity. Glycolic acid peels, being alpha hydroxy acids, are more aggressive and may not be suitable for sensitive skin. Beta hydroxy acids, typically derived from salicylic acid, are better suited for oily and acne-prone skin but could cause irritation in those with sensitive skin.

Therefore, the papaya enzyme peel is favored for its mild, soothing effects while still providing effective exfoliation for sensitive skin types.
