Acne is a common skin disease, often occurring in adolescents and young adults. It is not contagious because acne is a chronic inflammation of the sebaceous gland follicles, associated with excessive secretion of the sebaceous glands or infection with acne bacteria. It is not contagious and will not cause one's own acne by coming into contact with someone who has acne.

Can acne be squeezed?

Acne mostly occurs on the face, varying from mild to severe. Generally, there are some red, painful papules, and some may have white pustular papules. In such cases, try not to squeeze them. For some people with poor skin, acne scars or pits may form in the later stages, making treatment more troublesome. After the onset of acne, it is crucial to seek proper treatment at a dermatology department of a formal hospital. Oral and topical anti-inflammatory medications along with agents that clear internal heat should be used. Local treatment may involve red and blue light therapy. If there are indeed many pustules, a comedone extractor can be used to clean them appropriately. After recovery, it is important to avoid spicy and irritating foods, avoid staying up late, exercise regularly, and enhance immunity. (Specific medications should be taken under the guidance of a physician.)

The difference between acne and folliculitis

Acne and folliculitis, although both are skin diseases, have significant differences. Firstly, acne is caused by bacteria such as Propionibacterium acnes, while folliculitis is mainly caused by Staphylococcus aureus infection. Secondly, their treatments differ. Finally, the symptoms of acne and folliculitis are also different. Generally, folliculitis does not occur frequently, whereas acne does. Folliculitis initially presents as red papules that progress to pustules. Acne, on the other hand, displays various forms including papules, pustules, as well as blackheads and whiteheads.

Can hypertrophic acne scars be treated?

Acne, during its onset and treatment period, due to non-standard treatments or severe cases, coupled with some patients liking to pick or squeeze them, might lead to hypertrophic scarring later. Once hypertrophic scars form, they are not easy to treat, especially if they are very prominent, they generally cannot be completely cured. If the symptoms are mild, fractional laser treatment can be used, but the ultimate repair effectiveness is uncertain. If the prominence is especially noticeable, one can go to a dermatology department in a regular hospital for localized drug blockade treatment, but this only improves the symptoms and cannot eradicate the condition completely. Therefore, it is essential to follow standard treatment protocols during the onset of acne to prevent the formation of hypertrophic scars.

Can acne be covered with makeup?

Acne is related to vigorous sebaceous gland secretion, consumption of spicy and stimulating food, or frequent staying up late. It is a condition where, during the secretion process of the sebaceous glands, the follicle openings become blocked, leading to an accumulation of secretion locally. This is compounded by an infection of Propionibacterium acnes on the skin surface. During the treatment of acne, try to avoid makeup, especially oily makeup products that can clog pores, as these may exacerbate the condition or cause it to recur. Once this condition occurs, it is advisable to seek standard treatment at a dermatology department in a reputable hospital. Treatment can include oral and topical medications, combined with red and blue light therapy. Avoid picking or scratching the acne, as this can lead to scarring or hyperpigmentation later on.
