This is just my opinion, but it’s a decent method.
Start with a small bottle and fill it a few teaspoons shy of the top with a good carrier oil, like jojoba or almond. (about 40 ml or so)Pick out some essential oils that you think blend nicely (not too many though!), and add them, a drop at a time, to the carrier, capping and shaking regularly, until you get a scent you like.
Always err on the side of not enough, because you don’t know what it’s going to smell like until you wear it. You need to know if it causes a skin reaction, so always test!I wouldn’t suggest adding more than about 12 drops to the carrier oil, in case it gets too strong.
Once you get a scent you know you like, add the oil from a vitamin Ecapsule to help keep it. Let it sit for a few days, shaking it occasionally, to let the scents mingle.
Find a base oil. There are a lot of choices here. Many of the choices have other benefits, so you may want to compare.
Jojoba, for example, is an amazing conditioner for both skin and hair.
Arnica oil is great for massage – it reduces inflammation, helps aching joints, and helps heal bruises.
Another good choice is grapeseed oil, frequently used in moisturizers because of its antioxidant properties. It works on a cellular level to repair damaged and stressed tissues – including stretch marks – and restructures the skin by controlling the levels of moisture in the skin. It even keeps the nerve cells in the skin healthy.
If you are looking for a more economical base, vegetable oils such as canola oil, peanut oil, almond oil, and safflower oil, sesame oil, and soybean oil are all readily available in large quantities at the supermarket, and are great moisturizers as well.
Rice bran oil is also an economical choice, and it contains a lot of antioxidants that will make your skin glow.
Depending on how strong a fragrance you are adding, you can make a very cheap version by using olive oil, and you will still have incredibly smooth skin.
