Fragrance, also known as perfume or parfum, is an ingredient intentionally added to skincare products to impart a pleasant scent. While its primary effect is to enhance the sensory experience, its risk level of 8 warrants careful consideration. Due to this high risk, individuals with sensitive skin or known allergies should be particularly vigilant. It is advisable to patch-test products containing fragrance before widespread use and to opt for fragrance-free alternatives if irritation or adverse reactions occur.
