The mystery of friction melanosis has not yet been fully revealed, but the relationship between it and improper rubbing bath has been confirmed by experts.

It is characterized by light brown to dark brown pigmentation, diffuse network, high incidence in the clavicle, ribs, scapula, elbow, knee and other bone uplift. Let's share my experience with you.
What's the matter with melanosis?
According to the shape of the lesion, the specific predilection site and the investigation of the pathogenic factors, it is basically confirmed that the disease is caused by external local stimulation. The most eye-catching irritant is the health towel with nylon, rayon and cotton as raw materials. This kind of bath product is widely used in Japan, and users often use it to strongly rub the skin when taking a bath to achieve the purpose of skin health.
The change of epidermis is not obvious, but mainly in dermis, which is characterized by pigment incontinence. Most melanocytes were found in the upper dermis, especially under the dermal papilla. There were very mild infiltration of inflammatory cells around the dermal appendages and blood vessels. Eosinophilic corpuscles with dense nuclei were occasionally seen in the stratum spinosum of epidermis.
According to the history, clinical manifestations and pathology, it is easy to determine the diagnosis. It should be distinguished from macular skin amyloidosis, which is composed of punctate pigmented papules and characterized by amyloid deposition in dermal papillary layer.
