How to Choose a Lubricant: Water, Silicone, Oil, and Hybrid Compared

Lube makes sex, masturbation, and toy use more comfortable, and it can reduce friction-related irritation. But the lube aisle is confusing, and not every product suits every body, toy, or condom. This guide compares the four main types, explains which ones work with toys and condoms, and covers what the World Health Organization and recent clinical reviews say about sensitive skin, including two numbers most labels never show: osmolality and pH.

Who benefits from lube

Almost anyone can use lube, but a 2025 review in Canadian Family Physician highlights people who get the most benefit: those using condoms, and those who experience dryness, irritation, pain during sex, or sexual dysfunction (Vanderschee and Kostov, 2025). The review notes that vaginal dryness affects up to 15% of premenopausal and 90% of postmenopausal women, and that about two-thirds of women experience painful intercourse at some point. Lube is a normal, practical tool, not a sign that something is wrong.

The four types at a glance

Type	Feel and staying power	Cleanup	Toys	Latex condoms
Water-based	Light; can dry out, so you may need to reapply	Rinses off with water	Compatible with all common toy materials	Safe
Silicone-based	Very slippery; lasts long; does not wash away in water	Needs soap; can stain fabric; slippery on floors	Can degrade silicone toys	Safe
Oil-based	Thick, long-lasting	Hard to clean off	Can damage some materials, including elastomer sleeves	Not safe: weakens latex
Hybrid (water + silicone)	Between the two; creamier	Usually rinses off more easily than pure silicone	Check the maker's guidance, since it contains silicone	Generally safe; check the label

The toy and condom columns follow the Canadian Family Physician review, which states that water-based lubricants "are compatible with all materials found in items commonly used in the genital area," that oil-based lubricants can damage latex items such as condoms, and that silicone-based lubricants "can degrade silicone-containing devices, including sex toys" (Vanderschee and Kostov, 2025).

Simplified from the article's table, which follows Vanderschee & Kostov (2025) and WHO guidance. The toy maker's and condom box's instructions come first.

Water-based lube

Water-based lube is the default choice for most people. It works with every toy material and every condom type, and it washes off easily. The main downside is that it can dry out during longer sessions; adding a little more lube, or a few drops of water, usually fixes that.

Toy makers generally specify it. TENGA's AIR-TECH manual says to "use only water-based lotions," and iroha's FAQ says to use "ONLY water-based lubricants" with its vibrators, warning that silicone- and oil-based products may discolor or deform them. Lubes sold for Japanese masturbation sleeves ("hole lotions") are also water-based gels, usually made thicker so they stay inside the sleeve.

Silicone-based and hybrid lube

Silicone lube lasts much longer than water-based lube and keeps working in the shower. It is safe with latex condoms. The main caution is toys: because it can degrade silicone, many manufacturers say not to use it with silicone products. If you want to try it with a toy anyway, test a small hidden spot first and follow the toy maker's instructions over general advice. Silicone lube needs soap to wash off and can make floors and bathtubs slippery.

Hybrids mix a water base with some silicone, aiming for longer glide with easier cleanup. The Canadian Family Physician review lists "silicone-water hybrid formulations" among options that can be suitable. Because hybrids contain silicone, follow the toy maker's guidance before using one with a silicone toy.

Oil-based lube, and lube with condoms

Oils include products such as coconut oil, massage oil, baby oil, and petroleum jelly. They should never be used with latex condoms: the WHO Family Planning Handbook warns that lubricants made with oil can damage latex, and lists oils, petroleum jelly, lotions, and cold creams among products to avoid. The Canadian Family Physician review adds that petroleum jelly has been linked in several clinical studies to a higher risk of bacterial vaginosis, and recent data suggest baby oil may raise the risk of vaginal yeast infections. Oils are also hard to clean off toys.

Latex condoms: water-based or silicone-based lube only.
Non-latex condoms (polyurethane, polyisoprene, and others): compatibility varies by material. Read the condom box.

Does extra lube help condoms work? The WHO advisory note reviewed this. For anal sex, one study found condom breakage was 3% with the water-based lube supplied with the condoms versus 21.4% with no added lube. For vaginal sex, the evidence was mixed.

Breakage rates from one study reviewed in the WHO/UNFPA/FHI360 advisory note (2012), as described in the article.

Sensitive skin: osmolality and pH

Osmolality is a measure of how concentrated a liquid is. If a lube is much more concentrated than your body's own fluids, it can draw water out of the cells lining the vagina or rectum, which may irritate or damage them. Laboratory research has found that some over-the-counter lubricants with very high osmolality caused damage to tissue samples, while lubricants closer to the body's own concentration did not. The two silicone-based lubricants in the same study also showed no tissue damage (Dezzutti et al., 2012). These were lab tests on cells and tissue samples, not studies of people, but they explain why health agencies pay attention to this number.

The WHO, UNFPA, and FHI360 published an advisory note on lubricants in 2012. It recommends:

Osmolality: below 1,200 mOsm/kg. The Canadian Family Physician review suggests a stricter target of under 380 mOsm/kg where possible, with 1,200 as the upper limit when options are limited.
pH for vaginal use: about 4.5 (the review gives 4.0 to 4.5), to match the natural acidity of the vagina.
pH for anal use: about 5.5 to 7.0.

Most labels do not list osmolality. The review offers a practical shortcut: avoiding glycols such as glycerin and propylene glycol helps keep osmolality closer to the body's own level. Some brands do state "isotonic," "iso-osmolar," or a specific pH on their packaging or website.

Ranges from the WHO/UNFPA/FHI360 advisory note (2012) and Vanderschee & Kostov, Canadian Family Physician (2025), as given in the article. Most labels do not list osmolality.

Ingredients to skip if you get irritated easily

For people with frequent irritation or urogenital infections, the Canadian Family Physician review suggests avoiding lubes that contain:

Glycols: glycerin (glycerol), propylene glycol, PEG-8
Parabens: methylparaben, propylparaben, butylparaben
Chlorhexidine
Spermicides such as nonoxynol-9
Colors, dyes, fragrance, and flavors (especially sugar-based)
Warming, stimulating, or numbing ("desensitizing") ingredients

Many popular lubes, including some toy-brand lubes, contain glycerin or parabens. That does not make them unsafe for everyone. It means that if a lube stings or you get recurring irritation, switching to a simpler formula is a reasonable next step. Before using a new lube on genitals, you can test a little on the inside of your forearm.

Trying to conceive? Most lubricants reduce sperm movement. If you want a lube while trying to conceive, the review recommends fertility-friendly products with a pH of 7.2 to 8.5, osmolality of 270 to 360 mOsm/kg, and no glycerin.

Storage, shelf life, and when to stop using a lube

Store lube at room temperature, out of direct sunlight and away from heat and humidity. TENGA notes that long exposure to sunlight can turn its lotion yellow or make it thinner. Use opened bottles fairly quickly, avoid touching the nozzle to skin, and throw out lube that has changed color, smell, or texture or has separated.

If a lube causes burning, itching, redness, or swelling, wash it off with water and stop using it. If symptoms continue for more than a day or two, or you notice unusual discharge, sores, or pain, see a doctor, gynecologist, or sexual health clinic. Ongoing pain during sex has many possible causes and is treatable. This guide is general information and does not replace medical advice.

Quick picks by situation

With toys of any material: water-based.
With latex condoms: water-based or silicone-based.
In the shower or for long sessions without toys: silicone-based.
Sensitive skin or frequent infections: a simple water-based or silicone-based lube without glycols, parabens, fragrance, or warming agents.
Trying to conceive: a fertility-friendly lube as described above.
