Taqiyyah Qothrunnadaa, Aliya Nur Hasanah
Abstract
The purpose of this article review was to find out more about acne patch formulations and test stability. The method used is searching data from various articles based on Google Scholar, Elsevier, and Molecules with the keywords "Acne vulgaris, acne treatment, acne patches, and types of acne patches” and with a range of years between 2011 and 2021. Based on the type of acne, acne patches are divided into several types, namely microneedle patches, acne medicine patches, and hydrocolloid patches. The results obtained in this review show that the most commonly used acne patch is the medicated acne patch (hydrogel patches), because of its waterproof property to protect acne from secondary infection, it can absorb liquid inside and flatten acne and is cheaper compared to microneedles. The hydrogel patch is also stable at a temperature of 40±2 °C and a relative humidity (RH) of 75±5% for 6 mo of storage.
