Why Are There Small Spots on My Face?

Our skin often experiences various issues, such as acne or pustules caused by hormonal changes in the body or allergies. The appearance of numerous small spots on the face can be attributed to factors including physicochemical factors, biological factors, food and other diseases, genetics, neuropsychiatric factors, metabolism, and endocrine factors. Here are some examples:

Pressure and friction, rapid changes in local temperature, radiation, light exposure, thermal radiation, and chemical reagents can all trigger skin diseases. Some of these factors can exacerbate skin conditions, such as excessive scratching leading to secondary infection, hot water and soap washing worsening eczema lesions, and sun exposure aggravating photosensitive diseases.

Common pathogenic factors include insect bites, contact with certain plants, and parasitic and microbial infections, such as various viral skin diseases caused by viral infections.

Certain foods, such as shrimp, can easily trigger allergic diseases. Internal organ diseases, local infections, blood and lymphatic circulation disorders can also lead to related skin diseases. For instance, patients with diabetes are prone to pruritus, local infections can cause infectious eczematoid dermatitis, and circulatory disorders can result in cyanosis and elephantiasis.

Some diseases have a distinct family history, such as ichthyosis and albinism.

Nerve damage can lead to trophic ulceration. Stress, tension, alopecia areata, and chronic simple lichen planus are closely related to the occurrence of these conditions.

Metabolic disorders can cause skin amyloidosis, xanthoma, and other conditions. Cushing's syndrome is prone to acne and hirsutism.
