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.

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.

Will acne with pustules leave scars?

Pustular acne is considered a relatively severe type of acne. Without standardized and effective treatment, coupled with poor management such as scratching with hands and other adverse stimuli, it can lead to facial scars or acne pits. Therefore, it is necessary to enhance skin moisturization and sun protection, avoid spicy and irritating foods, and use medical skincare products such as acne clearing and scar diminishing creams, and acne repair serums. Oral medications such as Tanshinone IIA sulfonate capsules, Icariin tablets, and Vitamin A acid capsules, along with topical applications of Fusidic acid cream, Vitamin A acid cream, or Adapalene gel, are used. Additionally, physical treatments like fruit acid peeling and phototherapy with red and blue light are employed to provide anti-inflammatory effects and improve abnormal keratinization. (Note: Medication should be used under the guidance of a physician.)
