This review underlines the importance of different enzymes (beta-glucocereb
rosidase, phospholipase A(2), proteases and cholesterol sulfatase) in the f
ormation and maintenance of the epidermal barrier function. Certain disease
s may be characterized by the lack or excess of one or more of these differ
ent enzyme activities, altering the homeostatic equilibrium of the epidermi
s. In addition to this, particular enzymes may show potential in the develo
pment of novel dermocosmetic strategies.
