Hi, welcome to the forum, some causes for itchy pimples are folliculitis, fungal infection, acne or allergy.
Acne usually develops due to increased sebum production. Use mild skin cleanser and warm (not hot) water. Skin cleansers should be slightly acidic and intended for the face (rather than the body).
It needs to be differentiated from infectious folliculitis (secondary to infection) as skin is enriched with hair follicles. It may be due to bacteria like staphylococcus, streptococcus etc. Other possibilities are fungal infection (tenia barbae) or irritant dermatitis etc.
Picking or squeezing lesions should be avoided as this may worsen lesions and cause inflammation and scarring as your hands are prime source of infection. Moisturizers and Sun protection will help protect the skin.
Allergic manifestations can be managed by anti histamines and corticosteroids. Take consultation from a dermatologist. Take care and regards.
