The symptoms of acne are cutaneous. The skin has a greasy feel and a shiny appearance. On it develop pimples, preferentially on the face (nose, forehead, cheeks, chin), the neckline, and the upper back.
There are several forms of skin lesions typical of acne.
1 - The comedones
They are flat, even slightly raised, and centered by a black dot. Hence their name of "black dots". They sit on the oily areas of the skin.
2 - The microcysts
Recognizable by their color, they are commonly known as "white buttons". They are slightly elevated and contain a mixture of keratin, sebum, and keratin. Hence their white coloring. They can evolve unfavorably, in the form of comedones, or even be complicated by real inflammatory lesions (papulo-pustules).
3 - Papulopustules
These are the most aesthetically uncomfortable symptoms of acne. The papules are sometimes painful red, less than 5 mm in diameter, which can develop into pustules. This is the term given to them when they are surmounted by a purulent yellowish content.
4 - nodules
This symptom is rare, but it's the worst! The acne nodule is a deep inflammatory lesion that is more than 5 mm in diameter. It can be complicated by an abscess, and evolve into a scar.
