KP does not bear any known, long-term health implications, nor is it associated with increased mortality or morbidity. It is not related to goose bumps, which result from muscle contractions, except that both occur in the area where the hair shaft exits the skin. Gallery
Treatment
KP is medically harmless, but many individuals may seek treatment, as the condition can cause emotional distress. Topical creams and lotions are currently the most commonly used treatment for KP, specifically those consisting of moisturizing or keratolytic treatments, including urea, lactic acid, glycolic acid, salicylic acid, vitamin D, fish oil, or topical retinoids such as tretinoin. Improvement of the skin often takes months, and the bumps are likely to return. Limiting time in the shower and using gentle exfoliation to unplug pores can help. Many products are available that apply abrasive materials, with alpha or beta hydroxy acids to assist with exfoliation. Some cases of KP have been successfully treated with laser therapy, which involves passing intense bursts of light into targeted areas of the skin. Depending on the bodys response to the treatment, multiple sessions over the course of a few months may be necessary. Epidemiology
Worldwide, KP affects an estimated 30 to 50% of the adult population, and around 50 to 80% of all adolescents. It is more common in women than in men, and it is often present in otherwise healthy individuals. The skin condition is prevalent in persons of all ethnicities, and no particular ethnicity is at higher risk for developing KP.
The World Health Organization edition of the International Classification of Diseases 10th edition:version 2019 (ICD-10,  CIM-10 en français), lists BD as the subentry "Bouffée délirante without symptoms of schizophrenia or unspecified" under diagnosis code F23: Acute and Transient Psychotic Disorders subsection, F23.0: Acute polymorphic psychotic disorder without symptoms of schizophrenia. It is likely that the use of the term BD in French clinical psychiatry will decline further with the proposed 2022 implementation of ICD-11 (which was released in May 2019.) In contrast to the ICD-10, the term BD does not appear anywhere in ICD-11. The closest clinical match for BD in the ICD-11 is code 6A23, Acute and transient psychotic disorder which is defined as

acute onset of psychotic symptoms that emerge without a prodrome and reach their maximal severity within two weeks. Symptoms may include delusions, hallucinations, disorganization of thought processes, perplexity or confusion, and disturbances of affect and mood. Catatonia-like psychomotor disturbances may be present. Symptoms typically change rapidly, both in nature and intensity, from day to day, or even within a single day. The duration of the episode does not exceed 3 months, and most commonly lasts from a few days to 1 month. The symptoms are not a manifestation of another health condition (e.g., a brain tumor) and are not due to the effect of a substance or medication on the central nervous system (e.g., corticosteroids), including withdrawal (e.g., alcohol withdrawal).
