Synopsis

Rating (out of 5): 3

Hydrocolloid dressings have a scientifically validated role in the management of acne, particularly for superficial lesions such as papules and pustules. Hydrocolloids are occlusive, self-adhesive wound dressings that create a moist environment, promote healing, and absorb exudate. In the context of acne, hydrocolloid patches are not medicated but work through physical mechanisms. They absorb pus and oil from superficial acne lesions, reduce inflammation, and provide a barrier that discourages picking and manipulation, thereby decreasing the risk of secondary infection and post-inflammatory hyperpigmentation.

Several small clinical studies and in vitro experiments support their use. For instance, randomized controlled trials and split-face studies have shown that hydrocolloid patches can accelerate healing of inflammatory acne lesions compared to untreated controls. A 2017 study in the Journal of Cosmetic Dermatology demonstrated that hydrocolloid patches significantly reduced erythema and lesion size over a 7-day period. Additionally, their occlusive nature minimizes exposure to external irritants and bacteria. However, evidence is less robust compared to treatments that deliver active pharmaceutical ingredients, and effectiveness is limited to superficial acne lesions. Overall, their use is supported by moderate-quality scientific evidence as a supportive, non-pharmacological intervention for certain types of acne.
