About this ingredient
Trimethylcyclopentenyl Methylisopentenol is a synthetic fragrance ingredient. Its INCI matches the chemical name. In a formula it builds or adjusts the product scent and carries no skincare role. As a perfume component it is functional, not an active. It does not hydrate, soothe or improve the skin – it works on smell alone. If you want a visible result, look at other entries on the ingredient list rather than this one. Topically its systemic absorption is minimal, so it can be used during pregnancy and breastfeeding with no known restriction. The irritation potential is low, while the contact allergy risk is medium. Most people tolerate it well, but those sensitised to fragrances may get redness or itching. If your skin reacts to perfume, pick fragrance-free formulas instead.
