Acne is a chronic inflammatory dermatitis evolving in outbreaks. Typically, it begins at puberty and affects more than 80% of adolescents in a more or less severe form. It most often terminates spontaneously at the end of the adolescent period.
However, even if it tends to disappear in a relatively short period of time, compared with other chronic pathologies, this dermatitis, if frequent, may have an impact on the image and social life of the adolescent.
Acne is the reason for more than 20% of dermatologic consultations. An important psychological impact.
Psychological impact of acne is often very important as it occurs during a transitional period for the development of an individual: adolescence.
However, acne is also a pathology in which there is a gap between the lesion intensity and the impact on the adolescent; indeed, those lesions that do not show very often may cause a profound malaise and vice versa.
It makes the skin look oily and shiny. It is permanent and affects different areas: nose, forehead, cheeks and the upper chest. It is often difficult to diagnose.
Microcysts or closed comedos
Small white elevations ("white spots") of 2-3 mm. They usually go unnoticed and need to be pushed up to be revealed. They are due to accumulated sebum and keratin mixed with bacterial colonies. They are a true "time bomb" for acne; they can open and evolve as comedos or be where follicular walls break in the dermis causing inflammatory phenomena that leads to the creation of papules and pustules.
They are «black spots» or small corneal plugs of 1 to 3 mm on skin pores. They are made up of small compact yellowish oily filaments with a black end. They may spontaneously resolve and are rarely affected by inflammation.
They are inflammatory lesions with a diameter of less than 5 mm, where generally a microcyst finds its way out, and usually appear as red elevations, which are solid and sometimes painful, and may result in resorption or in the formation of pustules.
They are typically papulo-pustules on the upper part of which there appears yellowish purulent contents.
They are profound inflammatory lesions that typically result in the formation of scars. A nodule of acne typically has a diameter of more than 5 mm.
Nodules usually result in visible and persistent scars.
The aim is therefore to provide a line of treatments and hygiene treatments that allows:
> To reduce seborrhea
> To limit sebum retention and hyperkeratinization
> To prevent the development of P acnes and to check the inflammatory response
All of this should be done to give quick and visible relief to improve patients’ comfort.
Based on these criteria, Noreva laboratories have developed the lines : EXFOLIAC® , ACTIPUR®, ZENIAC®
