Balm, cream, lotion, salve, ointment, rub, gel. The shelf uses seven words for what looks like the same thing, and most of them are marketing rather than chemistry. There is one real dividing line, and once you know it the labels get much easier to read: how much water is in the jar.
The only distinction that actually matters: water
Nearly every topical falls into one of two families.
- Water-based (lotions, most creams, gels). An emulsion — water plus oil, held together by emulsifiers, and kept from spoiling by a preservative system. Lotions are the thinnest and most water-heavy; creams sit thicker; gels are water plus a thickener.
- Waterless (balms, salves, ointments). Oils and butters with a wax to set them. No water means no emulsifier and no preservative system, because there is nothing for microbes to grow in.
Everything people notice about how a product feels traces back to that one difference.
What water does to the feel
Water evaporates. That is why a lotion feels light and disappears fast — a good share of what you rubbed in has literally left. A waterless balm cannot evaporate; it softens at skin temperature, spreads thin, and stays where you put it. Less is needed, and what you apply stays put longer.
The trade-off is honest in both directions. Lotion spreads over a big area quickly and feels like nothing. A balm takes a moment of warming between the fingers and asks you to use a smaller amount than you think.
How to read a potency number without being fooled
This is where most of the confusion on the shelf lives. Two products can both say "2,000 mg" on the front and mean completely different things.
- Total milligrams per container tells you nothing on its own. 2,000 mg in a 2 oz tube is four times the concentration of 2,000 mg in an 8 oz pump bottle.
- Milligrams per ounce is the number to compare. If a label only shows the total, divide it by the size yourself.
- Check the size unit. Fluid ounces measure volume, ounces measure weight, and millilitres are volume. A 100 ml jar is about 3.4 fl oz.
For reference: Melrose Relieve is a 100 ml jar labeled 2,000 mg CBD (cannabidiol) per oz, broad spectrum, 0% THC. Do the same arithmetic to whatever you are comparing it against, and a lot of "high potency" claims get smaller.
Read the carrier list, not just the hemp line
The CBD is a small fraction of what you are putting on your skin. The rest of the jar is the product.
- In a waterless balm, expect oils, a butter or wax, and possibly menthol or camphor. Ours is beeswax, arrowroot powder, menthol crystals and botanical oils, with no synthetic fragrance.
- In a water-based cream or lotion, the first ingredient is water (often listed as aqua), followed by emulsifiers and a preservative such as phenoxyethanol. None of that is sinister — it is what keeps an emulsion safe on a bathroom shelf — but it is worth knowing it is there if you are checking for a sensitivity.
- Arrowroot powder or a similar starch is what takes the shine off an oil-based product, which is why a well-built balm can feel dry to the touch rather than greasy.
What menthol is doing
Menthol produces a distinct cooling sensation on the skin — that is the sensation people associate with a "rub". It is also the reason these products are noticeable in a small room, and the reason you keep them well away from your eyes. If you dislike that cool feeling, look for a balm without it; if it is the part you like, look at where menthol sits in the ingredient list.
Jar, tube or pump
Packaging is not just aesthetics. Waterless balms are usually jarred because they are too firm to pump. A jar means fingers in the product, so clean hands matter. Glass protects better than plastic — our jars are Miron violet glass, which blocks most visible light — while tubes and pumps keep air out and are easier to carry.
A fair way to compare two products
- Work out mg per oz for both, not total milligrams.
- Ask for a batch-specific third-party COA (certificate of analysis) that matches the lot code on the jar. Ours are published on our lab results page.
- Check whether the label and the website state potency the same way. Disagreement is a quality signal.
- Read the first three ingredients. That tells you which family you are in.
- Test on yourself, one area, for a week. Feel is personal and no spec sheet predicts it.
Where our balm sits
Melrose Relieve is deliberately in the waterless family: a 100 ml Miron glass jar, made in small batches, labeled 2,000 mg CBD per oz, broad spectrum, 0% THC, third-party tested, no water and no synthetic fragrance. It was built for a working massage clinic, which is why it is designed to stay put and spread thin rather than vanish on contact. You can read the full ingredient list and the lab reports before you buy: Melrose Relieve.
Frequently asked questions
Is a CBD balm stronger than a CBD cream?
Not automatically. Concentration is milligrams per ounce, and either format can be made at any concentration. What a waterless balm does differ on is feel: nothing evaporates, so it stays on the skin longer.
What does "waterless" mean?
No water in the formula. That means no emulsifiers and no preservative system, because a water-free product has no water for microbes to grow in.
Balm, salve or ointment — what is the difference?
In practice, very little. All three describe waterless oil-and-wax products. Ointment often implies a softer, greasier texture; salve is the older word; balm is the most common on modern labels.
Does a CBD balm feel greasy?
It depends on the formula. A starch such as arrowroot powder absorbs surface oil, which is why some balms feel dry to the touch shortly after application while others stay slick. Apply less than you think you need and give it a minute.
How do I know how much CBD is really in it?
The certificate of analysis, matched to the batch on the jar. A number on the front of a box is a claim; a COA from an independent lab is evidence.
