Rose acne is mostly a chronic skin inflammation that occurs on the face, with three stages including erythema, papulopustular, and rhinophyma periods. Allergic dermatitis, however, can occur as an acute inflammatory response of the skin on various parts of the body. Firstly, distinguishing between rose acne and allergic dermatitis depends on the location of the onset. Secondly, they are differentiated based on clinical manifestations. Thirdly, they are differentiated based on the condition of the disease. Rose acne is a chronic, recurrent, non-healing inflammatory skin condition, whereas allergic dermatitis is mostly transient and is a skin manifestation caused by allergic reactions. However, if allergic dermatitis occurs on the face, distinguishing it from rose acne can be challenging, and it is advisable to see a specialist in a formal hospital for an accurate diagnosis.

Does acne spread through contagion?

Acne is caused by the infection of Propionibacterium acnes. This condition is related to factors such as excessive sebum secretion of the skin, frequent consumption of spicy, greasy, and sweet foods, as well as regular late nights, anxiety, and stress. The disease is not contagious; it does not spread through contact with others, nor through sharing towels or bath scrubs. Once diagnosed, it is crucial to seek proper treatment to prevent the condition from worsening and potentially leading to scars or pits on the face. Treatment can be sought at a reputable hospital's dermatology department, where oral medication combined with topical treatments, and supplemented by phototherapy with red and blue light, can be effective. After recovery, it is important to regulate one's diet and lifestyle, avoid spicy and irritating foods, minimize staying up late, engage in exercise, bathe more frequently, and sweat more.

How to treat acne scar bumps?

Acne scars and keloids are often caused by improper treatment of acne or by scratching, squeezing, and breaking the skin during the treatment process, leading to infection and the subsequent formation of these scars and keloids. Once formed, it is impossible to completely remove them. If the keloid scars are not particularly prominent, you can visit a dermatology department at a standard hospital to repair them with fractional laser treatment. If the keloid scars are very noticeable and proliferative, you can also visit a dermatology department at a standard hospital for drug injection treatment, but it is not possible to completely remove them, only to temporarily relieve the symptoms. If the scars are relatively small, cosmetic surgery to excise them can be an option. Therefore, during the treatment of acne, it is crucial to follow standard practices and timely treatment, and to avoid scratching or squeezing the skin to prevent the formation of keloid scars.

What foods should not be eaten with acne?

Acne is a disease caused by an overactive sebaceous gland on the skin's surface and a concurrent infection with acne propionibacteria. The most common symptoms usually appear on the face as red or whitehead pimples. During treatment, it is essential to avoid spicy and irritating foods, such as chili peppers, lamb, seafood, alcohol, fried and greasy foods, or sweets, and try not to consume them. After recovery, it is also necessary to maintain a long-term regulated diet and lifestyle habits. Avoid staying up late, anxiety, and stress. Treatment should be carried out in the dermatology department of a formal hospital. Try not to pick or squeeze with your hands to prevent residual acne scars or pits. After recovery, appropriate exercise should be done to strengthen the immune system.

What department should you go to for acne treatment at the hospital?

Acne, also commonly known as acne vulgaris, falls under the scope of dermatology for treatment at formal medical institutions. This condition is associated with excessive secretion of sebum, consumption of spicy and stimulating foods, or frequent late nights. The skin surface infection is caused by Propionibacterium acnes. Once acne occurs, it is essential to seek formal and active treatment to prevent long-term issues such as facial scarring, acne pits, or hyperpigmentation. Effective treatments available in dermatology departments of formal hospitals include oral medications, topical medications, and adjunct therapy with red and blue light, which can hasten recovery. After healing, it is crucial to continue avoiding spicy and stimulating foods, refrain from staying up late, avoid misuse of cosmetics, frequently wash the face with warm water, and prevent recurrence of the condition.
