LIMONENE

Description

Limonene is a versatile terpene compound found naturally in the essential oils of citrus fruits, particularly lemons and oranges. This colorless liquid hydrocarbon is widely used in skincare formulations due to its pleasant citrusy aroma and potential benefits for the skin. Limonene possesses antimicrobial and anti-inflammatory properties, making it valuable in products targeting acne-prone or irritated skin. It also acts as a penetration enhancer, potentially improving the absorption of other active ingredients in skincare formulas.

In cosmetic applications, limonene serves as a fragrance component and solvent. Its ability to dissolve oils makes it useful in cleansing products and as a degreasing agent. However, limonene can oxidize when exposed to air, potentially causing skin sensitization in some individuals. For this reason, it's often listed as a potential allergen on product labels.

Limonene's antioxidant properties may contribute to protecting the skin from free radical damage. Some studies suggest it may have skin-brightening effects and could help in reducing the appearance of hyperpigmentation. When formulating with limonene, care must be taken to ensure its stability and minimize the risk of oxidation to maintain product safety and efficacy.
