"Why Do I Have So Many Red Spots on My Face?"

Numerous red spots on the face may be caused by allergic skin diseases, seborrheic dermatitis, acne, purpura, pityriasis rosea, and other conditions. It is recommended to prioritize skin care and consult a dermatologist for anti-allergic and antibiotic treatments. Here are detailed explanations for each condition:

1. Allergic Skin Diseases

Allergic skin diseases are often associated with an allergic constitution. Insect bites can lead to insect bite dermatitis, contact with allergens can cause contact dermatitis, and exposure to ultraviolet rays can result in solar dermatitis, all of which can cause skin redness and varying degrees of itching. It is advised to avoid allergens and take anti-allergic medications such as Loratadine or Cimetidine. If the itching is severe, topical glucocorticoid ointments like Triamcinolone Acetonide Ointment or Fluocinonide Ointment can be applied.

2. Seborrheic Dermatitis

Seborrheic dermatitis is linked to genetic factors and can occur on the scalp, face, chest, back, and neck, causing red patches and scaly skin flakes. It is recommended to apply Tacrolimus or Pimecrolimus Ointment under medical guidance, while also supplementing zinc and complex vitamin B.

3. Acne

Consuming spicy or greasy foods can stimulate sebum production. Blocked hair follicles can lead to localized congestion and swelling, resulting in red patches and pimples on the face. It is advisable to adjust one's diet, avoiding stimulating foods, and apply Erythromycin Ointment or Jixueganshuang Ointment under medical supervision for anti-inflammatory and healing effects.

4. Purpura

Purpura refers to subcutaneous bleeding, such as in the case of hereditary hemorrhagic telangiectasia, which can cause subcutaneous capillary bleeding and manifest as numerous red spots on the face. It is recommended to discontinue any suspected medications and provide coagulation factor supplements like Folic Acid, Ergocristine, and Creatinine as needed.

5. Pityriasis Rosea

The exact cause of pityriasis rosea is unknown but is thought to be related to medications, infections, or autoimmune factors. Patients typically present with rose-colored, fine scaly macules or papules on the skin, which can also appear on the face. Pityriasis rosea is self-limiting and may resolve on its own.
