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.

The main causes of acne formation

Acne is primarily caused by excessive secretion from one's own sebaceous glands. There are various reasons for this excessive secretion, such as genetic constitution and dietary preferences for spicy, fried, or sweet foods. Frequent staying up late, anxiety, tension, or mood disturbances can also lead to this condition. Some women may experience acne related to menstrual disorders or hormonal imbalances. Once acne is noticed, it is best to seek proper medical treatment and avoid squeezing or picking with hands to prevent scarring or pockmarks. Besides medical treatment, it is essential to maintain a long-term diet avoidance, regulate eating habits, exercise regularly to boost immunity, sweat more, and possibly take medications that reduce sebaceous gland secretion.

Can acne be cured?

Acne is caused by an infection of Propionibacterium acnes, and it is somewhat related to the overactive secretion of sebaceous glands. It predominantly occurs during adolescence, but some individuals may continue to experience symptoms into their 30s or even beyond 40 years of age. It is also related to personal diet habits, such as consuming spicy and irritating foods, or frequently staying up late. In some cases, there is a familial genetic link. Once this condition develops, it is crucial to seek proper treatment at the dermatology department of a regular hospital. Treatment can include medication combined with red and blue light therapy. After treatment, it is possible to completely cure the condition; however, acne tends to recur, so it is important to avoid spicy and irritating foods and to minimize staying up late to prevent relapse.

How to treat acne scars?

Acne is a disease caused by Propionibacterium acnes infection, with symptoms often more severe on the face. During the treatment of acne, if not handled properly or if the symptoms are severe, scars, pits, or post-acne marks may form after healing. Once these occur, there are no very effective medications available for treatment. It is possible to visit a dermatology department at a reputable hospital and use fractional laser treatment, which has decent effects. However, it may not be resolved in one session and could require many visits, and the costs can be high. Therefore, during the treatment of acne, it is crucial to follow a standard treatment regimen, avoid squeezing or picking at acne to prevent secondary infection, maintain a light diet, avoid spicy and irritating foods, and refrain from staying up late.

What happens if rosacea is not treated?

Rosacea, if untreated, mainly affects the appearance. It was formerly called rhinophyma and typically occurs in the central part of the face, manifesting as persistent erythema and dilation of capillaries, constituting a chronic inflammatory skin disease. The occurrence mechanism of rosacea is quite complex. It is related to consuming overly greasy, overly sweet, spicy, and irritating foods, and is also associated with frequently staying up late, anxiety, and insomnia, which can lead to the development of rosacea. In treating rosacea, it is important to avoid excessive cleaning of the skin to prevent damage to the skin's barrier function. It is also important to enhance skin moisturization and physical sun protection, avoid excessive cold or heat exposure, and manage stress. Diet-wise, it is advisable to refrain from drinking alcohol and avoid spicy and irritating foods.

Can acne be completely cured?

Acne is related to the excessive secretion of one's own sebaceous glands, the consumption of spicy and stimulating food, or frequently staying up late. In principle, it is not easy to completely eradicate, especially for adolescent patients, due to their age-related increased sebaceous gland secretion, who are also prone to regularly staying up late, encountering stress, anxiety, or tension. Therefore, for most cases, the condition can only be temporarily controlled or alleviated, with no way of achieving complete eradication. However, for older individuals aged thirty or even over forty, thorough eradication can be achieved through appropriate treatment and by regulating their dietary and lifestyle habits. The key is still to receive formal medical treatment at legitimate medical institutions and to regulate one's diet and lifestyle habits; otherwise, it will be difficult to eradicate the condition in the long term.
