What a pimple mark from nodular acne looks like

Nodular acne pimple marks are mainly red or dark brown in color and have a hard texture.
Nodular acne occurs when there is a large accumulation of sebum, which can lead to increased inflammation of the hair follicles and dilation of the capillaries, resulting in increased blood flow and thickening of the blood vessels, resulting in red acne marks, and hyperpigmentation after the inflammation, resulting in dark brown acne marks.
Nodular acne marks will gradually develop into thick nodules of varying sizes, usually located under the skin or above the surface of the skin, with a hard texture. Some nodular acne pimples may appear as blackheads and yellowish-white scum when squeezed. Scarring bumps may also form if infected.
When nodular acne exists, you need to go to the hospital for timely examination and treatment of acne under the guidance of a doctor to avoid leaving acne marks. Acne marks left behind by nodular acne can be removed by using photorejuvenation or lasers, avoiding scratching with your hands as much as possible, and protecting yourself from the sun.
