Lavender Oil carries an overall Moderate grade across the 10 studies linked on this page; the strongest signal is for anxiety/stress.
A quality improvement project (N=30) found statistically significant reductions in anxiety (p<0.001) and stress (p<0.001) using a blended aromatherapy intervention that included lavender in oncology patients; a broader review also supports essential oils, including lavender, as adjuncts for stress and anxiety management. However, the clinical trial used a blend (lavender, orange, peppermint), making it impossible to attribute effects to lavender alone, and the study lacked a control group.

Read the study on PubMed →Only one review article mentions lavender essential oil among several oils with potential anti-inflammatory, antioxidant, and antimicrobial properties for acne treatment. No specific clinical trials or controlled studies were found testing lavender oil specifically for acne.

Read the study on PubMed →A 2023 scoping review found only limited evidence for lavender's wound healing properties, noting that few studies have evaluated this specific application. The review primarily identified efficacy for pain relief and anxiety reduction, but wound healing was mentioned as an understudied area.

Read the study on PubMed →One small RCT (40 participants) found that a combination of lavender with other essential oils improved skin hydration and barrier function over 90 days. However, lavender was tested only as part of a multi-oil blend, making it impossible to isolate its specific effects on dry skin.
