Our skin plays a vital role in our beauty and appearance. Our age, the climate we live in, sleepless nights and the state of our health, as well as what and how we eat, are all revealed in our skin. This is why quality nourishment of the skin has to be maintained. Skin nourishment can take the form of topical applications or dietary intake, referred to as nutricosmetics.
Topical cosmetic applications have the benefit of bypassing many of the body’s protective barriers. The downside is that the very deep layers of the skin are often left unaddressed. Delivery of beauty ingredients via dietary intake, on the other hand, is challenging. Physical, chemical and enzymatic processing in the body reduces the chances of the beauty ingredient reaching the skin. However, when these barriers are crossed and the ingredient is delivered, an effect on the deeper layers of the skin can be achieved. The success of an ingredient in being systemically delivered to the skin may also be a sign of these components’ stability in biological systems, and of their fulfilling a functional need in the skin.
