Actives: Actives are the ingredients a product is built around: acids, retinoids, vitamins and the like.
In the research
7 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- A Cohort Clinical Study on the Efficacy of Topical Salicylic Acid/Piroctone Olamine Dandruff Pre-Gel and Cleanser in Improving Symptoms of Moderate to Severe Seborrheic Dermatitis · Journal of cosmetic dermatology, 2025
- Facial Seborrheic Dermatitis in HIV-Seropositive Patients: Evaluation of the Efficacy and Safety of a Non-Steroidal Cream Containing Piroctone Olamine, Biosaccharide Gum-2 and Stea · Clinical, cosmetic and investigational dermatology, 2022
- Treatment of cradle cap in infants with a new cosmetic non-steroidal gel cream: Clinical, laboratory, and instrumental evaluation · Journal of cosmetic dermatology, 2021
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.
