• Cosmetics ! Caution

Reviewed 7 October 2026 by an AI reviewer working to Yasno’s written review rules

What is Limonene?

Limonene gives products a fresh citrus smell; it occurs naturally in orange and lemon peel. As it's exposed to air, it changes into substances that can cause a skin allergy — itching, redness or a rash. If you have sensitive skin or eczema, it's one to watch, especially in old, long-opened products.

What is Yasno’s verdict on Limonene?
