Papaya Seed oil is a 100% natural carrier oil with a sweet, fresh, and fruity aroma. This nutrient-rich oil with natural exfoliating enzymes make this an exotic addition to cosmetic applications, personal care formulations, soaps, and hair care. Carrier oils are often used to dilute essential oils and absolutes before they are applied to skincare and aromatherapy products, but carrier oils are not suitable for diffusers.
