Inflammatory skin phenomena are some of the skin’s natural defence mechanisms against aggression of all
kinds (chemical, mechanical, UV, hypersensitivity, etc.). Inflammation is caused by exchanges between the
blood and tissue and involves the immune system.
It acts immediately and causes the production of inflammatory mediators (including cytokins and the PAF or
Platelet-Activating Factor) through an inflammatory cascade. This phenomenon is regulated, allowing the
physiological balance of the network of cytokins to be restored once the action is accomplished (the
elimination of the foreign particle, for example).<\/p>\n\n\n\n
However, if this inflammatory system is over-stimulated, an imbalance is caused, the inflammatory phenomena
are amplified uncontrollably and begin to snowball. The skin becomes a breeding ground for various
unpleasant sensations and redness and is no longer able to correctly regenerate itself.
Among these mediators, cytokins IL1, IL6 and TNF\u03b1 play an important role in each stage of the inflammatory
response.
The PAF, another inflammation mediator, is secreted by the different cells and nerve endings activated by the
inflammation. It pre-activates the cells by bonding with the cellular receptors to make them more sensitive to
the action of other mediators. It has an important role in amplifying the inflammatory reaction.

The origin of redness is most often the vasodilation of skin micro-vessels, linked to inflammation or micro-
trauma caused by the aesthetic procedure itself.
Because of the presence of smooth muscles in their walls, the capillaries in the dermis of the skin can dilate
under the influence of different factors, causing redness to appear.
This skin redness can be more or less pronounced and last for more or less time, and are the consequence of
numerous factors such as:<\/p>\n\n\n\n\n
micro-vessels, meaning that the risk of redness appearing is therefore greater,<\/li>\n\n\n\n
Poor blood circulation can also be the cause of such symptoms: with a struggling circulation and altered vein
walls, the blood stagnates and is diffused through micro-capillaries, causing a visible effect on the surface
which can go as far as causing a bruise to form, leading to a swelling of the skin.
Microcirculation is optimal when the skin’s network is well structured and the walls of the micro-vessels are
resistant. One growth factor is particularly important in the formation of <\/li>\n\n\n\n
Skin hydration is a cornerstone for the right balance and good condition of the skin.
Proper hydration is the key to the optimal function of skin cells and the proper organisation of different
compartments of the skin. It allows it to correctly fulfil its protective and heat regulation functions.
Dehydrated skin is a breeding ground for numerous malfunctions, leading to sensations of discomfort,
increased sensitivity to daily aggression and premature skin ageing. To guarantee and maintain a good level of
hydration, the skin has developed different mechanisms including the skin surface, also called the stratum
corneum. This impermeable surface layer, organised into “bricks and mortar” (corneocyte cells within a lipid
matrix), limits the entry of exogenic agents and the loss of water from lower layers.
The intercorneocyte lipids, organised in a multi-lamellar way, trap water and form a labyrinth that slows its
ascent to the skin surface.<\/p>\n\n\n\n
The NMF, made up of moisturising molecules within the corneocytes (mainly amino acids and their
derivatives), absorbs water in the atmosphere and retains free water from the deep layers of the skin, thanks
to its hygroscopic power.
