To create your own instant sunburn soothing solution, dilute 20 drops of lavender essential oil in a 1/2 cup of water, apply liberally with a mister. Do NOT substitute "Fragrance Oil" for lavender essential oil.
Be aware that while you CAN purchase "cheaper" brands of essential oil, you are likely getting Lavandin, which is NOT REAL Lavender essential oil, but perfectly legal for them to call it 100% real essential oil.
Lavandin does NOT contain burn healing properties, also lavandin has 12% more camphor which makes it even less suitable for use on burns.
Be sure to use TRUE 100% Therapeutic-grade
