What Are Hot Oils? Let’s Break It Down in Plain English
Okay, let’s start with the basics: what exactly are hot oils? I know when you first hear the term, you might picture a bottle of oil bubbling on the stove or something super heated—totally normal first thought! But nope, that’s not what we’re talking about here.
Hot oils, also called warming essential oils, are just plant-based oils that give you a tingling, warm, or even slightly spicy feeling when you put them on your skin. They don’t actually get hot to the touch like a boiling pan, but your skin will pick up that warming, almost spicy sensation, kind of like how your mouth feels after eating a handful of spicy chips. Wild, right?
Some of the most common examples of these warming oils include cinnamon, clove, lemongrass, oregano, and thyme. And wait, hold on—you might be thinking of peppermint right now, and yeah, peppermint gives a cooling tingle instead! A lot of people mix that up, so don’t feel bad if you’ve ever grabbed peppermint thinking it was a hot oil. I’ve definitely done that before, oops.
First Rule of Using Hot Oils: Always Do a Patch Test First
Let me be real with you here—before you slather any hot oil all over your body, you need to do a patch test. I cannot stress this enough. Everyone’s skin is different, and what works for your best friend might leave you with a nasty rash or way too intense of a burning feeling.
Here’s exactly how to do a patch test, step by step:
- Pick a small, easy-to-reach spot on your skin—your inner forearm is perfect, since it’s not super thick or sensitive but still shows reactions clearly
- Dab 1 or 2 drops of the undiluted oil (or the diluted mix you plan to use) right onto that spot
- Wait around 1 to 2 hours to see if anything happens. Most reactions pop up within 5 to 10 minutes, so you don’t have to stare at your arm the whole time, but keep an eye on it at least every few minutes!
If you start feeling a burning, itching, or notice redness, a rash, or swelling, wash the area off right away with mild soap and water. And don’t use that oil on your skin again—no matter how cool it looks!
Oh, and if you do have a bad reaction? Grab some carrier oil (we’ll talk about those in a second) and rub it onto the irritated spot right away. It helps soak up the essential oil and calm the burning feeling way faster than just water alone.
What’s the Difference Between Hot Oils and Regular Essential Oils?
Okay, quick terminology check here. A lot of people call these “hot essential oils,” but the official term is just “hot oils”—and that’s because it’s all about how they interact with your skin, not their actual temperature. They don’t heat up the oil itself, they just trigger that warm sensation on your skin’s surface.
Some folks might mistakenly call them “temperature hot oils,” but that’s not right at all! Like I said earlier, these oils don’t get warm to the touch before you put them on. The tingle is totally coming from how they react with your skin’s receptors.
Should You Dilute Hot Oils Before Using Them? Short Answer: Almost Always
Okay, let’s get into one of the biggest questions people have about hot oils: do you need to mix them with carrier oil? The short answer is yes—for beginners, anyway.
Undiluted hot oils are super strong. Like, I’m talking “I will make your skin feel like it’s on fire” strong. I’ve made that mistake before—once I tried dabbing a tiny bit of undiluted oregano oil on a pimple, and let’s just say I spent the next 20 minutes running to the sink to wash it off with cold water. Not fun.
But here’s the thing: once you’ve used these oils for a while and get a feel for how your skin reacts, you might start experimenting with undiluted uses. But even then, you should only do that on small, tough areas of skin—like the soles of your feet, for example. I’ve tried that with oregano oil before, and weirdly enough, I didn’t get that burning feeling at all! Your feet have thicker skin, so they can handle a lot more than your arms or face.
Diluting your hot oils doesn’t make them less effective, either. In fact, it usually makes them work better! Carrier oil helps the essential oil soak into your skin evenly, so you get the full benefits without irritating your body. Plus, it stretches your oil supply way further, which is great for your wallet too.
What Are Carrier Oils, and Which Ones Should You Use?
Carrier oils are just neutral, mild oils that you mix with essential oils to dilute them. They don’t have a strong scent on their own, so they won’t mess with the smell of your hot oil blend. Some of my go-to carrier oils include:
- Coconut oil (the fractionated kind is best, since it stays liquid instead of hardening up)
- Castor oil—super thick, perfect for really strong oils like oregano
- Jojoba oil—works for pretty much every skin type, no greasy leftover feel
- Sweet almond oil—gentle and smells a little nutty, which is nice
If you’re using a super strong hot oil like oregano, definitely grab a heavy carrier oil like castor oil. I tried diluting oregano with coconut oil once, and I still got that intense burning feeling on my wrist! But when I mixed it with castor oil, it was just the right amount of warm tingle, not overwhelming.
My Favorite Ways to Use Hot Oils (Without Burning Myself!)
Okay, now that we’ve covered all the safety stuff, let’s talk about how to actually use these oils without making a total mess of your skin. I’ve been using essential oils for a few years now, so I’ve definitely picked up a few tricks along the way.
My go-to daily use is lavender oil—wait, hold on, lavender isn’t a hot oil! I know, I know, but I wanted to mention it first because it’s my all-around favorite. I just dab a tiny bit behind my ears or on my wrists when I want a calm, relaxing scent. It’s perfect for winding down after a long day at work.
When it comes to actual hot oils, my favorite is oregano oil—even though it’s the strongest one out there. I usually mix 1 drop of oregano oil with 10 drops of castor oil, then rub it onto the soles of my feet when I’m feeling under the weather. A lot of people swear by oregano oil for supporting immune health, and it doesn’t give me that burning feeling on my feet like it does on other parts of my skin.
Another fun use is adding a few drops of cinnamon or clove oil to a carrier oil mix and rubbing it onto your temples when you have a headache. The warm tingle helps ease tension, and the scent is super cozy, like fall in a bottle. Just don’t get too close to your eyes, trust me—I’ve done that too, and it’s not pretty.
Common Mistakes People Make With Hot Oils (And How to Avoid Them)
Let’s be real, we’ve all made mistakes with essential oils before. Here are some of the most common slip-ups, and how to make sure you don’t do the same:
- Using undiluted oil on sensitive skin: Your face, neck, and inner elbows are super thin-skinned, so stick to diluted oils here, even if you’re a pro.
- Forgetting the patch test: I know it’s tempting to skip this step, but it’s not worth ending up with a painful rash. Take 5 extra minutes to do the test, you’ll thank yourself later.
- Using too much oil: A little goes a long way with hot oils! You only need 1 to 2 drops per blend, max. More doesn’t mean better, it just means more burning.
- Getting oil in your eyes or mouth: This is such a bad time. If you do get hot oil in your eyes, flush them out with warm water (not cold!) and call a doctor if it doesn’t get better after a few minutes.
Oh, and one more thing: never ingest hot oils unless you’re working with a certified aromatherapist! A lot of essential oils are toxic when swallowed, and hot oils like clove and cinnamon can burn your mouth and throat really bad. I’ve never tried eating any of my oils, and I don’t plan to, either.
Final Thoughts on Hot Oils: They’re Cool (Even Though They Feel Hot!)
At the end of the day, hot oils are such a fun and useful tool to have in your self-care routine. Whether you’re using them for a cozy scent, to ease muscle tension, or to support your immune health, they can make a big difference in your day—just as long as you use them safely!
Remember: start slow, do your patch test every single time, and always dilute your oils unless you’re 100% sure what you’re doing. And if you ever have a bad reaction, don’t panic—just grab some carrier oil and wash the area off right away.
I hope this guide helped you figure out exactly what hot oils are and how to use them without burning yourself! Let me know in the comments if you’ve tried any hot oils before, or if you have any favorite blends you love to use.
