There is no obvious single public parent that owns leading acne patch brands; the market is largely driven by private players such as Hero Cosmetics and COSRX. Direct public plays are therefore limited, but you can gain exposure through public skincare leaders with strong acne portfolios such as L'Oreal (LRLCY) and Estee Lauder (EL). Unilever (UL) also offers broad consumer skincare lines that touch acne-related segments and could benefit from rising demand for hydrocolloid patches. Entrepreneurially, a D2C acne-care brand or licensing hydrocolloid patch technology to retailers could capture margin as the category scales.
