Massage oil is incredibly easy. I like canola for that myself - cheap and nearly no odor, so it takes scents well. Jojoba is fantastic, as well, but expensive. If I have it, I usually combine it about 50/50 with canola. My signature blend is lavender, tangerine and ylang ylang. It’s relaxing without being soporific, and energizing without making you wired. It sounds like it would be overwhelmingly floral, but it’s really only vaguely floral. It’s mostly citrusy with a hint of bubble gum. I, too, do not like florals much. I’m more a sweet and savory kind of girl.
For a face cream, you could make a lotion with any or all of what you’ve listed, and chamomile, lavender, neroli, rose, rosemary, sandalwood - all depends on what you want it to do (and how much you want to spend!) Rosehip seed oil and carrotseed oil are also phenomenal in face creams (a serum is the oil/essential oils without the water of a lotion.)
Lip balm is simply oil, scent/flavor and beeswax. Grated beesewax or beeswax pellets are much easier to work with. If you have a block, then a microplane works pretty well to grate it. It will gunk the heck out of your microplane (or box grater) though. Best way to clean it is to soak it in hot water to melt it off the thing. You’ll need to heat the oil and stir in the beeswax until it melts. I like to use a chopstick to stir with - then I don’t lose a much product as if it’s all stuck over a spoon. I use a small metal spoon to catch just a few drops and then stick it in the freezer for a few minutes so I can check the stiffness. Too stiff, add some oil; too soft, add some beeswax.
For lip balm, I like peppermint and spearmint essential oils. (Doublemint lip balm!) I’ve also done cocoa (expensive and disappointing), tangerine (second favorite after doublemint), ginger (interesting) and lavender(ick, but a lot of my friends liked it.)
For a wonderful foot treatment, make an oil, balm or lotion, your choice, with peppermint and rosemary. Soooo nice on tired, sore muscles. Or fill a small wide mouth jar with Epsom Salts, and pour scented oil on it to fill. Instant foot scrub, way better than the scary purple stuff they use for a pedicure. (Do be careful, the bathtub will be very slippery as you rinse it off!)
I don’t like bath oils, because I don’t like the oil slick they leave on the top of the water. Instead, I mix my essential oils with some milk. That helps the scent disperse more evenly in the bathwater, and I don’t risk burning myself on the essential oils as I lift my body through the floating slick.
Remember, if you’re using essential oils, that they do NOT provide adequate preservation for long term shelf storage. Nor does Vitamin E - vitamin E is not antimicrobial (a preservative) although Vitamin E is an antioxidant, and will slow rancidity of your oils. But if you want to make something you can keep in a jar in your bathroom, you’ll need to add a synthetic preservative (except for the salt scrubs. There, the salt is your preservative.) Otherwise, make only what you’ll use in a few weeks’ time, and keep it in your refrigerator, or at least keep MOST of it in your fridge and only a small refillable container at room temperature.
Finally, label, label, label. You will think that you’ll remember how many drops of lavender and how many drops of peppermint you used, or whether you put in apricot kernel oil or almond oil. You won’t. If you want to be able to make it again write it down.
