A lubricant, a vulvar balm and a soothing care product do not do the same job, yet they are often put in the same category. Worse still, the most reassuring words on packaging — “natural”, “organic”, the name of a fruit — tell you almost nothing about what the product actually contains.
Here are a few pointers to help you read a label, and the three key things that matter: osmolality, glycerine, and the difference between a scent or flavour and an ingredient.
Osmolality: the number that almost never appears
Osmolality measures the concentration of dissolved particles in a liquid. In a lubricant, it determines something very concrete: will the product support the mucous membranes, or draw water out of them?
Vaginal fluids are around 370 mOsm/kg. A much more concentrated lubricant draws water out: it dries the area it is supposed to moisturise. A lubricant within this range simply does its job.
Very few manufacturers publish this information. When it appears in a product description, it is a sign of a serious approach. The Au Naturel water-based lubricant states 380 mOsm/kg, which is right within the physiological range.
Glycerine: a sugar, with everything that implies
Glycerine is a humectant widely used in lubricants. It retains water, provides glide and costs little. Chemically, it is also a sugar.
For many people, this causes no problem. For those prone to imbalances in vaginal flora or recurring yeast infections, it is something to watch. The same reasoning applies to added sweeteners in flavoured lubricants, such as sucralose.
If this concerns you, look for an explicit “glycerine-free” statement. The LELO moisturising lubricant and Au Naturel lubricant both carry it.
The “natural” and “organic” trap
Here is the most common mistake, and it makes perfect sense from the customer's point of view.
Natural and organic do not mean glycerine-free. These terms refer to the origin of the ingredients, not their absence. A lubricant can be certified organic and be based mainly on vegetable glycerine — this is the case with Toko natural organic lubricant, whose main ingredient is glycerine. The product is excellent, but it does not answer the question many people have in mind when choosing it.
The same logic applies to Mister Size, whose organic and premium versions share the same stated performance: what separates them is the origin of the ingredients, not the formula.
A scent is not an ingredient list
The third pointer concerns safety.
In many ranges, the product name describes the scent, not the ingredients. An oil described as “almond” may contain no almonds at all: it is a fragrance added to the same vegetable base used throughout the range. Conversely, that base may contain sesame, soya or sweet almond without the name giving any indication.
For someone with an allergy, the implication is clear: read the ingredient list, never the product name. This is true of every manufacturer, and it is why our product descriptions detail allergens even when the supplier does not.
Lubricant, moisturiser, balm: three different products
| Product | When to use it | What it does |
|---|---|---|
| Lubricant | During sex | Provides glide in the moment |
| Intimate moisturiser | Daily, outside sexual activity | Maintains the comfort of mucous membranes over time |
| Vulvar balm | Daily, on the surface | Nourishes the thinner, more reactive external skin |
Some products combine the first two uses — this is LELO's approach with its moisturiser. The third, however, never replaces the others: a vulvar balm is a skincare product, not a lubricant for sex. And like any oil-based product, it weakens latex condoms.
There are also aftercare products, such as intimate massage drops, whose benefits are best judged through regular use rather than a single evening.
Habits that help prevent problems
- External use. Unless explicitly stated otherwise, these products should not be applied internally.
- 24-hour patch test. Apply a small amount to the inside of your wrist before first use, even with a formula described as hypoallergenic. No cosmetic can guarantee that a reaction will not occur.
- Oil-based products and latex. Oils and balms weaken latex and polyisoprene. With a condom, stick to water or silicone.
- Silicone and accessories. A silicone lubricant can irreversibly damage a silicone accessory. Check the material.
- Period after opening. The small open-jar symbol indicates how many months the product remains usable once opened.
When it is no longer a cosmetic matter
Persistent dryness, recurring pain, repeated yeast infections, bleeding or irritation that does not go away call for medical advice, not a change of product.
Intimate care products are cosmetics. They support comfort; they do not treat anything. A doctor or midwife can identify in a consultation what no label can tell you.
SoPigalle tip: before buying, ask yourself just one question — when will I use it? During sex, daily, or afterwards? The answer eliminates two-thirds of the category, and labels become much easier to read.
FAQ: intimate care
What is a lubricant's osmolality?
It is its concentration of dissolved particles. If it is too high, it draws water out of the mucous membranes. Vaginal fluids are around 370 mOsm/kg.
Is glycerine a problem?
Not for everyone. It is a sugar, which may matter if you are prone to imbalances in vaginal flora or yeast infections.
Is an organic lubricant necessarily glycerine-free?
No. The organic label refers to the origin of the ingredients, not their absence. Some organic lubricants are based mainly on vegetable glycerine.
Does an “almond” oil contain almonds?
Not necessarily: it is often a fragrance. If you have an allergy, read the ingredient list rather than the product name.
Can a vulvar balm be used as a lubricant?
No. It is an external skincare product and is incompatible with latex condoms.
When should you seek advice?
Persistent dryness, pain, repeated yeast infections, bleeding or lasting irritation: these signs call for a healthcare professional.
