Cinnamon water for skin is a simple infusion you can make at home by steeping cinnamon in hot water, then using it as a toner or rinse. The active compound in cinnamon, cinnamaldehyde, has both antibacterial and anti-inflammatory properties, which is why this DIY remedy has gained popularity for acne-prone and aging skin. Here’s how to make it, use it safely, and what the science actually supports.
Choosing the Right Cinnamon
This step matters more than most recipes let on. The two main types of cinnamon sold in stores, Ceylon and Cassia, have very different safety profiles. Cassia cinnamon (the most common variety in the U.S.) contains up to 1% coumarin, a compound linked to liver toxicity at high doses in animal studies. Ceylon cinnamon, sometimes labeled “true cinnamon,” contains roughly 0.004% coumarin, so low it’s often undetectable in lab testing.
For something you’re putting on your skin regularly, Ceylon is the safer choice. You can find it at specialty grocery stores, health food shops, or online. It’s typically lighter in color and has a thinner, more papery bark compared to the thick, hard rolls of Cassia. If you only have Cassia on hand, it still works, but keep the concentration mild and don’t use it daily.
How to Make Cinnamon Water
There are two approaches depending on whether you’re using sticks or powder. Both work, but sticks produce a cleaner liquid that’s easier to apply to skin.
Cinnamon Stick Method
Break one cinnamon stick (about 3 inches long) into a few pieces and add it to roughly one cup (250 ml) of water. Bring the water to a gentle simmer, not a rolling boil, and let it steep for 15 to 20 minutes. The water should turn a warm amber color. Remove from heat, let it cool completely, then strain out the stick pieces. This gives you a mild infusion suitable for skin use.
Ground Cinnamon Method
If you’re using powder, start with about a quarter teaspoon of ground cinnamon stirred into one cup of warm water. Let it sit for 10 to 15 minutes. The powder won’t fully dissolve; it settles as a visible residue at the bottom. You’ll need to strain this through a coffee filter or fine cheesecloth before applying it to your face, otherwise the gritty particles can irritate skin.
In either case, start with a weak concentration. Most DIY recipes online are vague (“a pinch” or “a small spoon”), and people typically describe some trial and error before landing on a strength that doesn’t cause redness or tingling. A weaker batch is always safer than a stronger one, especially the first time.
Patch Test Before Applying to Your Face
Cinnamon is a known skin sensitizer. The cinnamaldehyde that gives it therapeutic potential is also the compound most likely to trigger allergic contact dermatitis. Reactions typically show up as redness, itching, or a burning sensation, sometimes appearing on the hands, face, or neck. While full-blown cinnamon allergy is considered rare, even mild irritation on facial skin can be uncomfortable and long-lasting.
To patch test, dab a small amount of your cooled cinnamon water on the inside of your forearm or behind your ear. Leave it on for 24 hours without washing it off. If you see redness, swelling, itching, or feel any stinging, don’t use it on your face. If no reaction appears after a full day, you can move forward cautiously.
How to Apply It to Your Skin
The most common approach is to use cinnamon water as a toner after cleansing. Soak a cotton pad with the strained, room-temperature liquid and gently sweep it across your face, avoiding the eye area entirely. Let it air dry for a few minutes before applying moisturizer.
You can also pour the cinnamon water into a small spray bottle and mist it onto your face. This gives you a lighter, more even application and works well if you find cotton pads too harsh on sensitive areas. A third option is to use it as a final rinse: splash it onto your face after washing, then pat dry with a clean towel.
If you have oily or acne-prone skin, you can try using it once daily, ideally in the evening after cleansing. If your skin is sensitive or dry, limit use to two or three times per week and watch for any signs of irritation over the first week or two. Any persistent redness or dryness is a signal to reduce frequency or dilute the mixture further.
What Cinnamon Water Can Do for Skin
The two bacteria most responsible for acne, P. acnes and S. epidermidis, are both susceptible to cinnamon extract in lab settings. A study published in BMC Complementary and Alternative Medicine found that cinnamon bark extract produced inhibition zones of 17.2 mm against P. acnes and 16.8 mm against S. epidermidis, indicating meaningful antibacterial activity. Beyond killing bacteria directly, cinnamaldehyde also reduces the production of inflammatory signaling molecules in the body, which helps explain why cinnamon has traditionally been used for red, inflamed breakouts.
There’s also preliminary evidence for anti-aging benefits. Research published in the Journal of Agricultural and Food Chemistry found that cinnamon extract stimulated the production of type I collagen in human skin cells. Collagen is the structural protein that keeps skin firm, and its production naturally declines with age. The study identified cinnamaldehyde as the active component, showing it activated a growth-factor signaling pathway that boosted collagen production without damaging the cells.
One important caveat: these studies used concentrated cinnamon extracts, not the dilute water infusion you’d make in your kitchen. A homemade cinnamon water is far less potent than the extracts tested in labs. The benefits may still translate at a milder level, but expect subtle, gradual effects rather than dramatic changes.
Storage and Shelf Life
Homemade cinnamon water contains no preservatives, which means bacteria can start multiplying in it quickly. Water-based herbal preparations are generally recommended to be used within 24 hours at room temperature. If you refrigerate your cinnamon water (below 40°F), you can extend that to about 48 hours. Keeping it cold slows bacterial growth but doesn’t stop it entirely.
The practical solution is to make small batches. One cup at a time is plenty for a few days of use when refrigerated. Store it in a clean, sealed glass jar or bottle. If the liquid develops an off smell, looks cloudy, or has been sitting for more than two days in the fridge, discard it and make a fresh batch. You can also freeze cinnamon water in an ice cube tray and thaw one cube at a time for use, which keeps it fresh much longer.
Potential Risks and Who Should Avoid It
People with known fragrance allergies should be especially careful, since cinnamaldehyde is a common component in fragrance mixes used for allergy testing. If you’ve ever reacted to perfumes, scented lotions, or cosmetics containing cinnamon, skip this remedy entirely.
Avoid applying cinnamon water to broken skin, open acne lesions, or freshly exfoliated skin. These areas are more permeable and more likely to react. If you’re pregnant, dealing with eczema or rosacea, or using prescription acne treatments like retinoids, the added irritation from cinnamon water is generally not worth the risk. Stick with products formulated and tested for sensitive skin instead.
