Infiltrating the largest organ of the human body and reaching
its deep dermal layers is key to stimulating the renewal of
cells. Many attempts have been made, but the results have been
disappointing due to poor formulation and poor vitamin stability.
Scientists at Inter-Cal set out to prove that Ester-C®
Topical could reach down to deep layers of the skin where
collagen and other important support structures are produced.
In an independent test, Ester-C®
Topical (14% vitamin C) and a cream containing 1%
Topical were applied in a randomized pattern to eight sites
on the skin of the inside forearms of five subjects. The
test showed that vitamin C from both were able to penetrate
the skin barrier to access the cells and tissues involved in
the maintenance and repair of skin.
