C. Insect bites

Insect bites, especially mosquitoes, fleas, or bedbugs, often result in localized red spots that can be itchy or painful. The skin reacts to the saliva injected during the sting, resulting in inflammation and the characteristic red bump. These spots are usually benign and disappear on their own, although severe allergic reactions can occur in some individuals.

D. dermatitis

Dermatitis can manifest as red spots or spots. Contact dermatitis results from exposure to irritants or allergens, while atopic dermatitis (eczema) can result from genetic factors or environmental causes. Both forms can cause significant discomfort, including itching and redness.

E. Inflammation of the hair follicles

Folliculitis is an inflammation of the hair follicles, which is often caused by a bacterial or fungal infection. It appears as red, pus-filled bumps around the hair follicles, which are usually found on the scalp, face, or feet. Treatment usually includes proper hygiene and may include topical or oral antibiotics.
