Detailed answer

Lavender oil has hydrating properties that can help replenish moisture in dehydrated skin. It acts as an emollient, which means it forms a protective layer on the skin to prevent water loss. This helps to lock in moisture and keep the skin hydrated. Additionally, lavender oil contains compounds that can soothe and calm the skin, reducing inflammation and redness often associated with dryness. Its ability to improve the skin's barrier function also aids in preventing further water loss and promoting overall hydration. However, it's important to note that lavender oil may cause sensitization or irritation in some individuals, so it's always recommended to perform a patch test before using it on the entire face.
