Applying a cream with nutrients to the surface of you skin does not ensure
that those nutrients actually penetrate into your skin cells.
They may just "sit there" until your next shower.
How much of the active ingredients actually get into your skin cells
depends on the skin's condition, concentration of the ingredients,
manufacturing technology and many other factors.
This doesn't mean that all topical preparations are useless
-- but they are often unreliable. On the other hand,
when the nutrients are ingested and absorbed into your bloodstream,
they are sure to be delivered to your skin cells.
Nutrients does more for your skin!!!
