Blue light
Light is necessary for life, but long exposure to artificial light is becoming a major health concern.

Skin penetration
In cosmetic industry and more generally in chemical formulation, it is important to understand active ingredients effects and how far they penetrate the different skin layers.

Case studies
Skin barrier
Epidermal differenciation triggers to the formation of apoptotic cells, corenocytes more or less cohesive. One of the main role of these cells is to regulate epidermis permeability. The skin barrier is due to the accumulation of lipids.

Hair protection
Hair is a constant victim of many agressions : water, sun, brushing, pollution, having shine and smooth hair with blow dryers and heating irons… The robust structure of its external layer, the cuticle, protects it.

Evaluation of production of extracellular matrix components
Collagen is one of the major constituents of dermis, the intermediate layer of skin. It is one of the most abundant protein in human and is composed of long polypeptide chains also called procollagene.

Case studies
Tensing effect
The dermis is largely composed of dense collagen-rich extracellular matrix (ECM). Dermal collagen represents by far the most abundant ECM protein and constitutes the bulk of skin.

Plumping effect
Should skin pumpling a synonym to collagen production ? Yes certainly but not only. Stimulating microcirculation, moisturizing, nourishing are also effects to promote.

Slimming effect
A slimming cream might have several actions depending on its target. It can regulate and balance storage and removal of fat. In this context, studying adipocytes, the responsible cells for fat storage in adipoe tissue, sheds light on its action’s mode.

Smoothing effect
Skin mobilization is the result of the different mobility capacities of the skin and its underlying structures. When the skin is stretched and mobilized, there is an elastic restoring force opposite to the axis of tension,which tends to return the skin to its previous state.

Wound healing
Wound healing is a very complex process, specific to every organism and tissue, and addresses several factors and different cellular and tissular groups.
