Lavender is one of those plants that seem to pop up everywhere in the natural skincare world, and with good reason: it has natural antiseptic and anti-inflammatory properties, but is super gentle and can be used by basically anyone. Another reason it’s everywhere: it smells great, and the flowers yield a good amount of oil when distilled, making it relatively inexpensive. Smelling lavender has been shown to reduce anxiety and promote restful sleep.
