Clinical Characteristics and Treatment of Acne with Sensitive Skin

Background. Acne is a prevalent skin disorder that primarily affects seborrheic areas. It occurs due to hair follicle obstruction and subsequent inflammation. Patients with acne often exhibit compromised skin barrier function and sensitivity, making treatment challenging. Objectives. This study aimed to investigate the occurrence of acne complicated by sensitive skin and explore the associated physiological changes. Methods. The lactic acid test and capsaicin test were employed to identify subjects with simple acne and those with acne and sensitive skin. Physiological characteristics were assessed in both groups. Two random groups were selected from the subjects with acne and sensitive skin. One group received treatment for acne alone, while the other group received combined treatment for acne and sensitive skin care. The efficacy and physiological function of the two groups were compared after treatment. Results. Among 170 acne patients, 99 were identified as having acne with sensitive skin. Patients with acne and sensitive skin exhibited significantly higher scores on the lactic acid test and capsaicin test compared to those with simple acne. They also showed increased transepidermal water loss (TEWL), decreased skin cuticle hydration (SCH), thinner epidermis, and thicker blood vessels. The group receiving combined treatment demonstrated a more significant reduction in the number of skin lesions and IGA scores compared to the group receiving treatment for acne alone. They also exhibited lower scores on the lactate and capsaicin tests, along with decreases in TEWL and increases in SCH. Conclusions. Acne with sensitive skin is highly prevalent and is associated with distinct physiological characteristics. Combined treatment targeting both acne and sensitive skin yields excellent clinical outcomes and improves skin's physiological function. These findings underscore the importance of considering sensitive skin in the clinical management of acne.
