Frequently asked questions
What does Thioglycerin do in skincare?
Thioglycerin is a cosmetic ingredient used in skincare formulas. The catalog calls its main role “depilatory.” In plain language, it is used in products made to remove hair. The catalog lists 3 other possible roles for this ingredient. These labels do not prove that it treats a skin condition.
Is Thioglycerin a fungal-acne (Malassezia) trigger?
Caprylic/capric triglyceride (MCT) is built from C8 and C10 fatty acids — both at or below the chain length Malassezia needs to grow at all, per the foundational 1968 study (fatty acids must be longer than C10). Glycerin and propanediol are a different case entirely: they're simple humectant polyols, not fatty acids or fatty-acid esters, so there's no lipid for Malassezia's lipases to act on in the first place. Generally well-tolerated on fungal-acne-prone skin.
