Science & Benefits
Cinnamyl Alcohol is a naturally occurring aromatic alcohol found in Cinnamon leaves and Balsam of Peru. It is legally classified as one of the 'EU 26' fragrance allergens because it is a potent sensitizer. When applied to the skin, it can induce a Type IV hypersensitivity reaction (allergic contact dermatitis). While it carries a zero comedogenic rating, the resulting inflammation causes follicular swelling and micro-papules that look identical to an acne breakout. For a bulletproof skincare routine, this ingredient is a major red flag for anyone with sensitive, reactive, or eczema-prone skin, as it provides no functional benefit while carrying a high inflammatory risk.
