What is the primary function of azulene oil?

The primary function of azulene oil is to soothe the skin. Azulene is a compound derived from chamomile and has anti-inflammatory properties, making it effective in calming irritated or sensitive skin. This soothing quality helps to reduce redness, swelling, and discomfort, providing relief to various skin conditions.

While other options like hydrate, exfoliate, and brighten refer to important skin care functions, azulene oil is primarily recognized for its soothing action, which can be beneficial after treatments that may cause irritation or inflammation.
