Lube Guide: Water, Silicone, Oil? The Right Choice For You

Nobody ever gave you a lesson on lubes. You find yourself at 10 PM in a Coop Vitality aisle, scanning ingredient lists you don't understand. That's what we're here for.

To put it simply: a water-based lube is the Swiss Army knife, compatible with everything. Silicone-based is the marathon runner, super long-lasting and perfect for the shower. Oil, however, is just for massages, because it destroys latex condoms. That's the basic info.

Why lube isn't just an "extra"

Let's get one thing straight right away. Using lube doesn't mean something's "wrong". It's not a sign of a lack of desire. It's just a smart tool. Your body's natural lubrication isn't an on/off switch. It varies with your cycle, your stress levels, if you're taking certain medications, or just your mood of the day. That's normal. That's life.

A good lube is your ally for more comfort and less friction. It makes everything smoother, prolongs pleasure, and reduces the risk of micro-tears or irritation. It's also a protective measure. A condom is much less likely to break when things are nice and slippery. That's a fact. Even the advisors at PROFA, the sexual health centre, systematically recommend it. It's a basic for well-being, not a niche accessory.

The three teams: Water, Silicone, Oil

Your choice of lube depends on what you're planning to do. Each base has its strengths and rules to follow. Think of it like choosing the right tyres for the right season. You wouldn't use summer tyres to go to Verbier in January.

Team Water: the Swiss Army knife

This is the most common, most versatile. The all-rounder. A water-based lube is compatible with absolutely everything: latex condoms, polyisoprene condoms, and all imaginable accessories, whatever their material. It doesn't stain sheets and cleans up super easily with a bit of water. It's the safe default option.

Its only minor flaw? It can dry out a bit quickly during long sessions. Don't panic. Just add another drop or reactivate it with a little saliva. It's the ideal choice if you're just starting out or if you don't want to overthink it. It's also the only type of lube compatible with all types of protection, a topic we cover in detail in our condom guide.

Team Silicone: the marathon runner

Silicone is the superior division of glide. The sensation is ultra-silky, almost velvety, and it lasts. Really long. A single application can be enough for an entire session, which is pretty handy. Since it doesn't contain water, it's perfect for an adventure in the shower or bath. Water doesn't dilute it.

The trap to know: silicone doesn't like silicone. NEVER use it with a silicone intimate accessory. The lube will attack the object's surface, making it porous and sticky – in short, unusable. You don't want to ruin something that cost you 80 CHF. For everything else (glass, metal, ABS plastic), it's open season.

Team Oil: the massage specialist

Oils (coconut, sweet almond, or dedicated formulas) smell lovely and are great for the skin. For a massage, they're top-notch. They nourish, they glide, it's a super vibe. But be careful, this is a specialist with serious contraindications.

Oil and latex are mortal enemies. An oil can create micro-perforations in a latex condom in less than 60 seconds. This has been lab-tested and confirmed by the OFSP. So, if you're using latex or polyisoprene condoms, oil is a no-go. Period. It's also not recommended for vaginal penetration, as it can disrupt pH balance. Keep it for relaxing moments and caresses, an art we explore in our guide on the subject.

The ingredient list, your best friend

The other day, a customer from Geneva wrote to us: "I thought I was sensitive to lubes, but it turns out the one I was using was full of glycerine. I switched to a clean formula and no more issues." It's often as simple as that. The devil is in the details. Here are the ingredients to watch out for:

• Glycerine/Glycerol: This is a sugar. It can give a pleasant texture, but it can also feed the yeasts responsible for thrush. If you're prone to that, choose a formula without it.
• Parabens: Controversial preservatives. Most good brands have eliminated them, but still check. Better safe than sorry.
• Nonoxynol-9: This is a spermicide. We now know it irritates mucous membranes and can increase the risk of STI transmission. Avoid it.
• Fragrances and flavourings: Nice for oral use, but sugars and aromatic compounds can unbalance intimate flora. Use them for what they're intended for.

Let's bust a myth: "If it stings, it's working"

No. Just no. A lube should never sting, burn, or create a sensation of discomfort. Never. If it does, it's a sign of a reaction to an ingredient (often propylene glycol or a fragrance). Your body is telling you to stop. Listen to it. Products tested and approved in Switzerland, like the ones we select, follow established standards to minimise these risks. A good lube makes you forget it's there. It's just there to make things more pleasant. Full stop.

Your scenario, your match

No need to become a chemistry PhD at CHUV to understand a label. Here's a simple summary:

• For a session with a latex condom: Water-based, always. Or silicone. Never oil.
• For a marathon under the covers: Silicone-based. It goes the distance.
• For a shower adventure: Silicone-based. It's the only one that resists water.
• For a solo moment with silicone accessories: Water-based. It's the only 100% safe option for your accessories.
• For a sensual massage: A dedicated massage oil. If things escalate, clean thoroughly and switch to a compatible lube.

The simplest thing is to go for brands that have already done the sorting for you. If you want to see the formulas we've approved, without weird ingredients and discreetly delivered to your home by Swiss Post (with 8.1% VAT already included, of course), take a look at our selection of lubes. We've chosen the best so you don't have to.

Frequently Asked Questions

Does lube expire?

Yes, absolutely. Like any cosmetic product. The expiry date is indicated on the bottle, often with an open jar symbol (e.g., 12M for 12 months). An expired product can lose effectiveness, change texture, and potentially cause irritation. Respect the date to stay safe.

Can I use Coop coconut oil?

For an external massage, why not. But it's a very bad idea with latex condoms, which it will weaken. For intimate use, it can also disrupt your natural pH and encourage imbalances. It's better to stick to products specifically formulated and tested for this use.

Are "warming" lubes safe?

They are generally safe, but they're not for everyone. The warming sensation comes from ingredients like capsaicin (a chilli derivative) that stimulate nerve endings. Always test a small amount on your skin (the inside of your wrist) before applying it to more sensitive areas. If you have sensitive skin, avoid it.

How much lube should I use?

There's no strict rule; it depends on you, your partner, and the situation. Start with a pea-sized amount (the size of a 1 CHF coin) and adjust as needed. The goal is comfortable glide without being excessive. The important thing is not to hesitate to reapply if friction sensations return.
