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 people with acne drink milk?

Patients with acne can drink milk. Milk contains high protein, calcium, iron, and zinc, which have certain therapeutic effects on acne. Drinking milk does not exacerbate or cause a recurrence of acne. Acne is related to vigorous secretion of sebaceous glands or local skin infection by Propionibacterium acnes. Once the disease occurs, it must be treated according to standards. Avoid spicy and irritating foods, do not stay up late, and you can take oral and topical anti-inflammatory drugs. Combining red and blue light treatments can hasten recovery. Try not to use cosmetics indiscriminately, especially those that are greasy and likely to clog pores. During treatment, try not to scratch or pop pimples, as this can lead to pigmentation or scarring. (Specific medication should be conducted under the guidance of a physician.)

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.

Is acne the same as pimples?

Acne is a medical term, commonly known as pimples or acne. These two are the same disease, caused by the infection of Propionibacterium acnes, and are related to one's own active sebaceous glands, eating spicy and stimulating food, or frequently staying up late. Once diagnosed with this condition, it is important to receive systematic and formal treatment to prevent recurrence. Treatment can include oral and topical medications from a dermatology department in a formal hospital, and combining this with red and blue light therapy may yield better results. Avoid scratching or popping the acne, as this can lead to scarring or pits. After recovery, it is crucial to maintain a proper diet and lifestyle over the long term, avoiding staying up late and consuming spicy and stimulating foods to prevent the condition from recurring.

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.)

Can acne scars be removed?

If acne is not treated properly or promptly, it may worsen and develop into cystic acne. Additionally, if individuals frequently scratch, squeeze, or pick at the acne during treatment, infections can form and ultimately result in residual scarring. Once scars have formed, they are not easily fully repairable. If the scar proliferation is not too severe and is relatively flat, fractional laser treatment can be temporarily used for repair. If the scar proliferation is more pronounced and protrudes significantly, it is necessary to seek treatment in a proper hospital with medications and injections for closure therapy. However, these methods can only temporarily soften or shrink the scars, and cannot completely remove them. Therefore, the most fundamental approach is still to manage the treatment effectively to prevent residual scarring. Upon detection, it is crucial to follow standardized treatment protocols and avoid scratching or bursting the acne.
