Causes

Sensitive skin specifically refers to a high-response state of the skin under physiological or pathological conditions, which may present subjective symptoms such as burning, tingling, itching, and tightness, with or without erythema, telangiectasia, and desquamation objective signs. Mainly occurs on the face.

Epidemiology

Sensitive skin has a high incidence rate in all countries in the world, and the reported incidence rate varies greatly from place to place. It is 25.4% to 89.9% in Europe and about 50% in Australia. The incidence rate of women is generally higher than that of men. Females are 22.3% to 50.9%, Asian females are 40% to 55.98%, and the incidence rate of females in my country is about 36.1%.

There is still a lack of research on the incidence rates among different ethnic groups in different regions of my country. With the change of people's skin care methods, the abuse of cosmetics or excessive cleaning, the increasing environmental pollution and the increase of mental stress, the incidence rate is gradually increasing, and more and more people pay more and more attention to it.

Disease type

Primary sensitive skin

Caused by genetic, mental factors, etc., certain physical factors (such as seasons, weather, temperature, pollution, etc.) can induce or aggravate.

Secondary sensitive skin

Secondary to the abuse of skin care products to damage the skin barrier, suffering from facial dermatitis, and not paying attention to skin care after photoelectric treatment.

Individual factors

Mainly include genetics, age, gender, hormone levels and mental factors. Studies in recent years have shown that sensitive skin is related to genetics; the incidence of young people is higher than that of the elderly, and women are higher than men; mental stress can reflexively cause the release of neurotensin, which causes sensitive skin.

External factor

Physical factors: such as season alternation, temperature change, sun exposure, etc.

Chemical factors: such as cosmetics, cleaning products, disinfection products, air pollutants, etc.

Latrogenic factors: such as external use of stimulant drugs, local long-term application of large amounts of external glucocorticoids, inappropriate photoelectric therapy, chemical peeling, etc.

Secondary to other skin diseases

Such as rosacea, hormone-dependent dermatitis, cosmetic dermatitis, etc.
