The science of light and skin

Radiance and luminosity, both essential to youth and beauty, closely depend on skin quality. But what actually is radiance? It is the light that is diffused and reflected by the skin. The smoother, more homogeneous and more regular the skin's surface, the more intense the skin's luminosity. 

Therefore, the main factors involved in loss of skin luminosity are surface imperfections and irregularities, such as wrinkles, dehydration lines, dry patches, brown spots, redness and excess sebum, which create shadows on the face and alter the refraction of light.

But light also penetrates the skin's deeper layers, which, depending on their composition and condition, will re-emit these luminous rays with greater or lesser intensity.

Healthy, moisturised skin with a cohesive structure and high-quality constitutional substance retransmits intense light, revealing a fresh and radiant complexion.

Skin that has lost its structure and homogeneous density, with cells that are less cohesive and essential components that have been damaged, becomes opaque and loses its ability to diffuse light. It becomes dull, pale and less translucent.
