Anti-aging products


Autumn 2012, YonKa launched The Stimulastine Jour & Nuit program the anti-wrinkle innovation that mature skin had been waiting for, a double act of anti-aging creams, two complementary products which effectively combat deep set wrinkles. Keeping your skin plump will reduce visible wrinkles but there is so much more needed to reduce the depth and sharpness of the wrinkles than can occur in mature skin.

“Elastin is a protein in connective tissue that is elastic and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched. Elastin is also an important load-bearing tissue in the bodies of vertebrates and used in places where mechanical energy is required to be stored. In humans, elastin is encoded by the ELN gene.[1]” . – sourced from wikipedia

In time, the skin’s “scaffolding” a protein called “Elastin” breaks down, causing this normally horizontal connecting structure to become vertical and thereby allowing wrinkles to become deeper and more defined. Providing the correct nutrient for these Elasin proteins allows them to return to their usual horizontal position, decreasing the depth and definition of mature wrinkles. Visible results: up to 64% less wrinkles*. Skin is visibly younger.

Stimulastine Jour & Nuit


The dermis thins with age. The elastin fibers’hich make up the skin’s support network, deteriorate. Skin progressively loses its elasticity, leading to the formation of fine lines.
The anti-wrinkle Stimulastine Jour & Nuit program acts on the elastin on 3 levels: it protects it, stimulates its synthesis and improves its quality.

The ingredients:
The Stimulastine Jour & Nuit duo is composed of 92% natural ingredients. Both creams are paraben-free.

The silky Stimulastine Jour cream is quickly absorbed. It contains Boswellia resin extract with anti-wrinkle – anti-elastase virtues.
