Dermatology
Some essential oils are recognized for their moisturizing, softening, nourishing, astringent, firming, and anti-acne properties. However, caution is advised, applying pure essential oil directly to the skin is not recommended. It is always better to dilute it in a vegetable oil.
Dosage recommendations vary depending on the essential oils, but generally, it is appropriate to mix 30 drops of essential oil into 50 ml of vegetable oil. The mixture can be applied to all parts of the body, avoiding mucous membranes and the eye area. In local application, this mixture can alleviate various skin problems (acne, redness, dryness...) as well as insect bites, blows, bruises...
Caution! Some essential oils are photosensitizing and it is advised not to expose oneself to the sun for at least 4 hours after application. Others can cause allergic reactions. Always perform a preliminary test in the crook of your elbow.
