Acne

Mild acne is characterized by whiteheads and blackheads, small, non-inflamed bumps that dot the skin's surface. In addition, you may notice small red bumps or pimples, some of which may contain pus, indicating slight inflammation. Generally, these lesions are less than 30, and not all appear red or inflamed.

Allergies

Experiencing allergies, or hay fever, typically brings sneezing, nasal congestion, and itchiness in the nose, eyes, or throat. These symptoms often last over a week, distinguishing them from common colds. 

Canker Sores

Canker sores are marked by painful, white or cream-coloured ulcers, often less than 1cm, surrounded by a raised red border. They typically form inside the cheeks, lips, sides of the tongue, or on the mouth's roof or floor, causing sharp pain in affected areas. 

Cold Sores

Cold sores typically present as a rash or bumps around the lip's edge, often accompanied by a clear fluid discharge. Before these visible symptoms, you might experience itching, tingling, or burning sensations. The affected skin area usually becomes red or inflamed, signalling the onset of a cold sore.
