11. Lichen Planus

Red spots on the skin may result from autoimmune diseases like lichen planus, affecting various body areas. This condition, characterized by flat, itchy, purple rashes, can manifest in the mouth, nails, scalp, genitals, eyes, throat, and digestive tract.

Although the cause of lichen planus remains unclear, experts suggest a potential genetic link. It predominantly affects women and individuals aged 30 to 60. Notably, lichen planus is non-contagious, and while it may resolve on its own, recurrence is possible.

Diagnosis involves a physical exam by a healthcare provider. Treatment options include topical steroids, retinoids, or oral antihistamines to alleviate symptoms associated with lichen planus.

12. Petechiae

Red spots resembling a rash, known as petechiae, result from burst blood vessels beneath the skin. They are smaller and more diffuse than cherry angiomas.

Petechiae suddenly appear on the arms, legs, stomach, and buttocks, spreading without itching. Not a condition itself, but a symptom linked to infection, trauma, bleeding disorders, or allergies.

Seek a provider’s help to identify the cause. Infections such as fungal, viral, or bacterial, including strep throat and scarlet fever, are known triggers.

If petechiae aren’t spreading and show no signs of infection, treatment may not be necessary. However, the presence of fever suggests a potentially serious infection requiring immediate attention.

13. Pimples (Acne Vulgaris)

Red spots, often pimples, appear on the face, chest, and upper back due to blocked pores from oil, dead skin cells, and bacteria.

Mildis acne  treatable at home with over-the-counter products. Cystic acne, a severe form, may need dermatologist intervention. Treatments include topical medications, oral antibiotics, isotretinoin, steroid injections, chemical peels, and hormonal contraceptives.
