Patchouli oil is widely used in the fragrance industry for its rich, earthy, and musky aroma, making it a popular ingredient in perfumes, colognes, and scented products. It is also a key component in aromatherapy, where it is believed to promote relaxation, reduce stress, and improve mood. In skincare, patchouli oil is valued for its antiseptic and anti-inflammatory properties, often incorporated into creams, lotions, and soaps to help treat skin conditions like acne, eczema, and dermatitis. Additionally, it is used in hair care products to strengthen hair and address issues like dandruff and scalp irritation. Beyond personal care, patchouli oil is utilized as a natural insect repellent and in the production of incense and candles for its calming scent.
