Couperosis is an alteration of the vascularization
of the dermis of the face and neckline which is expressed in the onset
of redness. It corresponds to a network of telangiectasia on a
background of erythrosis.
It is more common in skins that are thin, white,
sensitive and pallid, which redden easily because their epidermis is
very thin. The elasticity of these peripheral vessels is virtually zero.
If the blood flow suddenly increases and the capacity for elastic
recovery is scarce, this redness may easily occur.
The formation of couperosis is influenced by
external factors (chemical agents, contusions, environmental exposure)
and internal ones (digestive disorders, nervousness, stress,...).
