
Mode of Action:
 Polysaccachrides act as
moisturizers
 Stimulates the
fibroblasts to replicate
faster
 Smoothes skin because
sticks epidermal cells
together which
normally flake
 Interferes with
melanin deposit
production which lead
to “liver spots”

insulin secretion
Decrease in cholesterol,
triglycerides,

clearance and decreased
transporters
