Research shows that no matter how good the contain ingredients of cosmetics are usually impossible when leather part, especially for the molecular weight of hyaluronic acid (HA, only it is impossible to apply skin absorbed by leather.
Hyaluronic acid (hyaluronic acid) HA cosmetics only applies to daub skin surface, increase in the surface of the skin hyaluronic acid (hyaluronic acid) HA content, nourishing and moisturizing effect, is localized, external cause.
And hyaluronic acid (hyaluronic acid) HA with oral after digestion and absorption, can obviously increase the body hyaluronic acid (hyaluronic acid) HA synthesis of precursor, make the skin and other tissues of hyaluronic acid (hyaluronic acid) increased HA synthesis, thus make the skin water increased performance, full of elasticity and reduce wrinkles.
Its hairdressing health care function is systemic, is from leather to skin increased endogenous hyaluronic acid (hyaluronic acid) content of HA, increase the amount of blood microcirculation, cell activation, give play to the role of the body, is endogenous, and local use cosmetics has obvious different.
Therefore, to maintain the function of collagen, it is necessary to supplement endogenous hyaluronic acid (hyaluronic acid) HA, even if the external cause must pass through the inside and thus function.
