Dermatology is the specialty in medicine that applies to the greatest number of patients

Dermatology is the specialty in medicine that applies to the greatest number of patients; in fact, more than 1 in 3 people suffer from a skin disease [SD]. Despite these impressive data, public health and prevention policies pay little attention to SD patients and SD are hardly ever a public-health-priority.

The ALL PROJECT involves 50,552 individuals, representative of the adult populations of 20 countries spread over 5 all five continents [China 5000, USA 5000, Brazil 4001, India 3000, Australia 2000, France 4000, Italy 400, Canada; Denmark; Germany; Israel; Kenya; Mexico; Poland; Portugal; Senegal; South Africa; South Korea; Spain; UAE ], which together accounts for over 50% of the world's population. In each of the 20 countries surveyed conducted a population-based study on representative and extrapolable samples of the general population aged 16 years or more.

The questionnaire was built in partnership with patient organisations and remains focused on the patient's experience and feeling.

Thus, all-territories, all-generations, all-phototypes, all-dermatoses have the chance to be in the limelight.

Thus, the ALL-project is the project of all skin, all dermatoses, and all colours.

This type of study, in which the same questionnaire was administered at the same time across the globe, highlights the universality of the feelings and experiences of those suffering from skin diseases.

The results of this unprecedented study, constitute a unique database.

This database will allow establishing a real advocacy to better defend to the authorities of all countries the need for global awareness and interest as regards a public-health-policy to support-patients suffering from a SD.
