Patient Information Leaflets (PILs)
These Patient Information Leaflets (PILs) are specially written by the British Association of Dermatologists (BAD).
The BAD has been awarded The Information Standard certification for the process it employs to develop information products aimed at the general public, which include PILs, Sun Awareness Campaign materials, and other information products.
The BAD shall hold responsibility for the accuracy of the information published, and neither the scheme operator nor the scheme owner shall have any responsibility for costs, losses, or direct or indirect damages or costs arising from inaccuracy of information or omissions in information published on the website on behalf of the BAD.
There are thousands of different skin complaints, therefore, the focus of the British Association of Dermatologists' PILs production is on the most common, rarest or debilitating skin conditions.
The offer to provide details of source materials used to inform the British Association of Dermatologists' PILs is for instances where the advice provided in the PILs does not reflect local practice and therefore evidence supporting said advice needs to be produced. It is not an offer to conduct literature searches or supply bibilographic materials for your own research.
Keratosis pilaris (KP) is a very common and may be present in half the population. It is a completely harmless skin condition. It affects 50-70% of adolescents and approximately 40% of adults. Its name gives some idea of what it is; ‘keratosis’ means that there is too much keratin, which makes up the tough horny outer layer of the skin, while ‘pilaris’ comes from the Latin for hair (pilus). In keratosis pilaris, many small (1 to 2 mm across) horny plugs can be seen blocking the hair follicles on the upper and outer parts of the arms and thighs. This can look like goose bumps but feels slightly rough. Keratosis pilaris appears when extra keratin accumulates in the hair follicles. This usually starts in childhood and becomes more obvious during adolescence and in adulthood. For reasons not fully understood the condition seems to be better in the summer than in the winter perhaps because in winter the skin often gets dry while in summer the sweat makes it less dry. Keratosis pilaris may be associated with ichthyosis vulgaris and atopic eczema, however this may be coincidental.
