Cedrus Deodara Wood Oil, or Himalayan Cedarwood oil, offers a multi-functional approach to skin health.

Summary

Astringent Antimicrobial Anti-inflammatory Antioxidant Sebum Regulator Fragrance

Science

Mechanism of Action

This oil functions as an astringent by tightening skin tissues, which visually refines texture and reduces pore prominence. Its antimicrobial and antiseptic properties, attributed to sesquiterpenes like cedrol and cedrene, actively inhibit the growth of blemish-causing bacteria. Anti-inflammatory components such as α-cedrene and caryophyllene contribute to reducing skin redness and discomfort. Additionally, it offers antioxidant protection against free radicals, regulates sebum production to reduce oiliness, and exhibits fungicidal actions, supporting overall skin healing.

Sensitization risk Moderate

Generally recognized as safe (GRAS) by the U.S. EPA for topical use when adhering to label instructions; however, the European SCCS reports some evidence of contact allergy in humans. While irritation is rare when properly diluted, direct contact with concentrated forms can cause moderate inflammation and sensitization. Always dilute in a carrier oil and perform a patch test. Avoid application near eyes, inner nose, ears, or other sensitive areas. Not advised for pregnant or nursing women due to potential hormone interference, and ingestion is strongly discouraged as it can be damaging to internal organs.
