👉 Archive pimples, also known as cystic or nodular acne scars, are a type of skin scarring caused by deep, inflamed acne lesions that fail to fully resolve. When an acne lesion becomes infected or becomes trapped beneath the skin, it can lead to a more severe inflammatory response, resulting in a large, painful, and often red nodule or cyst. These lesions can become trapped beneath the skin's surface, causing the formation of a keloid scar or a more permanent scar. Unlike superficial pimples, archive pimples do not resolve with time and can leave behind noticeable, raised scars that significantly impact skin texture and appearance.
