Cause
The cause of oily dermatitis
Causes:
The oil color consists of four parts: pigment, base oil, filler and essence. Any of these ingredients can cause the disease due to quality factors. The pigments of the oil color are neutral, Sol, Red, Yin Zhu R, and Sunfast Yellow G are all sensitized. It is more effective than nisani azo dyes, and the latter two are nitroazo organic pigments that have both photosensitivity and sensitization. They are the main cause of the disease; impurities in pigments and some inorganic substances. Lead, flavor, base oil, etc. in pigments (such as iron oxide red) are also pathogenic substances.
In addition to the oil color itself, base oil, eyebrow pencil, lipstick, makeup powder, cleansing oil, sticky gum (containing rosin, dilute ammonia solution) and nasal putty (for modeling), soap for makeup remover, paper quality and makeup removal method The outdoor performance of the wind and the sun, the atmospheric humidity and other stimuli have a certain impact on the skin reaction, using halogen halogen lamps, xenon lamps, xenon lamps and other new light sources for stage lighting, where the ultraviolet light is not filtered, and some in the oil color Some pigments and fragrances are organic substances with light-sensing effects. Under strong light, especially long-wave ultraviolet (UVA), they often cause photo-sensing dermatitis or pigmentation. Self-allergic constitution is also an important factor in the pathogenesis.
Pathogenesis:
Partly due to the primary stimulating effect of the pigment or its impurity components, another part of the case is caused by the sensitization of the organic pigment, or both effects.
