What is sensitive skin?

Sensitive skin is an overreaction of the skin to environmental factors. Patients who suffer from this condition often say that when their skin comes into contact with cosmetics, soap, and sunscreen, they often react excessively, even in dry and cold climates.

This type of condition is often accompanied by itching, burning, stinging or tightness, although irritating symptoms are usually not observed. Even over-reactive substances are generally considered to be unstimulated. These materials include various cosmetic materials such as dimethyl sulfoxide, benzoyl peroxide, salicylic acid, propylene glycol, amyldimethylaminobenzoic acid and octyl methoxycinnamate, and the like.

Although sensitive skin and subjective irritation are common phenomena, they cannot be explained and understood very clearly.

In fact, sensitive skin is a type of skin that is hypersensitive to stimuli. Usually, the barrier is incomplete, the permeability of the stratum corneum is increased, and the sensitivity of the nerve reaction is high. Hypersensitivity may be due to a decrease in keratinocytes resulting in a thinning of the stratum corneum, resulting in a change in the transdermal permeability of the water-soluble compound. A comparison of different stimuli found that 14% of the sensitive skin in the normal population is associated with thinning of the stratum corneum, and thinning of the stratum corneum makes these individuals more sensitive to chemical stimuli.

In addition, related studies have pointed out that sensitive skin has a decreased barrier function due to the loss of intercellular lipids in the stratum corneum. Barrier function is not the only cause of sensitive skin, but also other predisposing factors – structural changes in the nervous system or epidermis. (Water and dermatitis, PGP9.5 nerve fiber density and length changes). Recently, some scholars have used non-invasive methods to conduct in-depth investigations on the characteristics of sensitive skin, and classified sensitive skin into three types according to various physiological parameters. Type I is a fragile state of the barrier function. Type II is a normal state of inflammation and inflammatory disease. Type III barrier function is a normal sub-health state. Among all three types of sensitive skin, high density nerve growth factor (NGF) was found compared to non-sensitive skin. Among them, type II and type III sensitive skin are highly sensitive to electrical stimulation. These studies have shown that the high response of sensitive skin is closely related to highly active nerve fibers in the epidermis.

Sensitive skin is both a subjective and objective expression term. The subjective feeling of sensitive skin is the discomfort caused by external stimuli, tingling, burns, itching and tightness that the patient can feel. Sensitive skin phenomena are difficult to interpret due to the lack of clinical signs. These subjectively stimulating individuals are mainly characterized by lower water content, rougher skin, erythema and telangiectasia. Among them, erythema phenomenon and dryness in water shortage are particularly obvious.

Sensitive skin is a skin syndrome that is sensitive to external factors. To find a way to effectively improve skin sensitivity, it is important to understand the mechanism of sensitive skin. Some subjects showed subjective symptoms such as itching, burning, tingling, and tingling. The reason is not clear. Increased permeability of the stratum corneum and increased neuroreactivity are possible. 40% of people report sensitive skin, 50% of sensitive skin patients have discomfort, but no symptoms of inflammatory reaction. Non-invasive methods can be used to predict the adverse effects of some individuals on cosmetics. All of these efforts are critical to improving the tolerance of cosmetics. In addition, if sensitive skin involves multiple causes, interventions must be taken that match the appropriate mechanisms. Therefore, different types of skin should be treated according to different mechanisms of differentiation to alleviate their sensitive symptoms.
