- Maintaining a youthful appearance and / or healthy skin and / or hair leads to the unceasing search for new compounds and / or new non-invasive methods of treatment to maintain or improve the appearance of the skin and / or hair.
- the aim is to prevent and / or reduce visible and / or tactile irregularities of the skin and / or the hair.
- the term "skin imperfections of oily skin” is understood to mean, in particular, aesthetic disorders such as a shiny skin, poorer makeup hold, a thick skin texture generally associated with a defect in desquamation, a skin whose follicular orifices are dilated (increased visibility of the pores) or filled with tiny horny spicules, or even with comedones or blackheads (resulting however more from a phenomenon of retention than from an increase in the excretion), a loss of radiance and / or transparency of the skin.
- the appearance and / or visibility of pores in particular is particularly increased in people with dilated pores and / or excess sebum, particularly in people with Asian or Caucasian skin.
- a shiny or oily skin is generally a hyper-seborrhoeic skin characterized by an excessive secretion and excretion of sebum generally leading to a sebum level greater than 200 ⁇ g / cm 2 measured at the forehead.
- Sebum is the natural product of the sebaceous gland which is an appendage of the pilosebaceous unit. It is essentially a more or less complex mixture of lipids.
- the sebaceous gland produces squalene, triglycerides, aliphatic waxes, cholesterol waxes and optionally free cholesterol (Stewart, ME, Semin Dermatol 11, 100-105 (1992)).
- the action of bacterial lipases converts a variable part of the triglycerides formed into free fatty acids.
- the sebocyte constitutes the competent cell of the sebaceous gland.
- the production of sebum is associated with a program of terminal differentiation of this cell.
- the metabolic activity of the sebocyte is essentially focused on the biosynthesis of lipids (lipogenesis) and more precisely on the neosynthesis of fatty acid.
- sebum is normally a natural moisturizer of the epidermis
- the overproduction of sebum can lead to aesthetic inconveniences, such as shiny skin, poorer makeup, increased visibility of the pores, the formation of comedones or black dots, a loss of radiance and / or transparency.
- Sebum may also be a favorable medium for the colonization of P-type bacteria. Acnes involved in acne.
- the skin imperfections of oily skin may be more or less visible depending on the phototype of the subjects; in particular, they are more visible on the skin of subjects with a high phototype, that is to say skin of subjects with phototype III to Vl, defined according to the Fitzpatrick classification which is based on the reactivity of the skin to the effects solar radiation: I always burn, never tans
- the oily skin of men's faces, subject to daily shaving, is also particularly prone to skin lesions.
