I have some laser burns on my face that I’m trying to get rid of (the “professional” used the wrong laser, and now I have reddish brown nickel sized burns on my face). I’ve researched and found that Geranium, Helichrysum, Lavender, Neroli, and a few others are good for scars, burns, etc and they all blend well together. My question is can I blend them all (since they each have a unique power, if you will) and how much do I use of each?

You need a cool-air diffuser. These diffusers usually require a small amount of distilled water to be added along with essential oils. Note: Cold air diffusers ranges vary, with most around 250 feet. So if you are trying to diffuse your bedroom and living room, most likely you will need two diffusers. This one is my favorite for the money and size/features.
