What's wrong with the light red papules

Usually when the seasons change, people's skin becomes particularly sensitive, and it is easy to develop some skin diseases at this time, such as light red papules. This is a symptom that often appears on the skin. Most patients will not feel any pain or itching after the onset, but will just feel that their skin is red. However, as the disease worsens, they will gradually feel the appearance of itching, which can easily affect the patient's sleep quality and cause great damage to the skin. Therefore, it is necessary to find the cause of the disease in time after the light red papules appear, so that the right measures can be taken as soon as possible for treatment.

It could be folliculitis

A polymorphic rash that occurs anywhere on the body, manifested as small papules and papulovesicles with symmetrical distribution, unclear edges, and a pronounced tendency to exudate, erosion, crusting, and scaling, sometimes accompanied by infiltration and hypertrophy, severe itching, frequent recurrences, and a chronic course.

It could be eczema

It is common in areas with more sebaceous glands such as the scalp, face, upper chest, upper back, armpits, and genitals. The basic lesions are erythema, papules, and yellow greasy scales or scabs on the surface, with varying degrees of itching; the distribution is symmetrical, and can cause thinning and loss of hair.

It could be seborrheic dermatitis

It is prone to occur in areas prone to friction (more common in young or middle-aged people) such as the neck, extensor side of the elbow joint, sacrum, and around the eyes (especially the upper eyelids). The local skin first has severe itching, and due to repeated scratching, triangular or polygonal, skin-colored or light brown flat papules consistent with the skin texture may appear. The rash is dry without exudation, the surface is dry, and it feels firm. It can be densely packed into pieces, forming lichen-like plaques, and there may be scratches, blood scabs and pigmentation on the surface.

It may be neurodermatitis

It is more common in young men and women (women develop the disease earlier than men, and men have more severe symptoms than women), and is prone to occur in areas of the face, chest and back where sebaceous glands are abundant. There are two types: whiteheads and blackheads. When squeezed with hands, milky white sebum plugs can be seen being squeezed out. Follicular inflammatory papules are often caused by bacterial infection. There are pustules on the top of the papules, and punctate atrophic scars are left after healing. If the inflammation is severe, deep, pea-sized, dark red, hard nodules with porous blackheads, multiple penetrating abscesses, sinus tracts, nodules, cysts, and hypertrophic scars may be seen.
