- Condition GuideFolliculitis that looks like acneIn folliculitis, red papules and pustules of similar size may appear simultaneously around the hair follicles, and itching can be prominent. In contrast, acne often involves a mix of skin changes of varying sizes and depths, such as comedones (blackheads and whiteheads). Since bacterial folliculitis and Malassezia folliculitis require different treatments, they are difficult to distinguish from a single photo.→
- Condition GuideBack acneBack acne is not caused by poor hygiene; rather, it fundamentally occurs when sebum and dead skin cells clog the pores, leading to inflammation within the hair follicles. The back has many sebaceous glands, and heat and sweat easily become trapped under sportswear, backpacks, or protective gear, which can increase friction. If itchy pimples of similar size suddenly spread, other diagnoses such as bacterial or Malassezia folliculitis may be possible, so a dermatology evaluation is necessary.→
- Medical Evaluation GuideHow do acne, folliculitis, rosacea, and perioral dermatitis differ?If comedones, such as blackheads or whiteheads, are mixed with various types of inflammation, it is closer to acne. If similar-sized pimples appear in each pore and are itchy, folliculitis is considered; if persistent redness and burning sensations in the center of the face are prominent, rosacea is considered; and if small rashes cluster around the perimeter of the lips, perioral dermatitis is considered. A diagnosis should not be confirmed by photos alone; the affected area, itchiness, products used, and response to treatment must be evaluated together.→
