Choosing the right lubricant and vaginal moisturiser for you

Lubricants and vaginal moisturisers often get spoken about together, but they do very different jobs, and picking the wrong one with the wrong ingredients can do more harm than good to a delicate area of the body.

Here's what each is actually for, why you might need one (or both), and how to choose carefully.

Lubricants: reducing friction and tissue damage during penetration

A lubricant's job is simple: reduce friction. It's used at the point of activity, not as an ongoing treatment. That might mean during:

• Sexual intercourse or sexual activities
• Solo or partnered use with a vibrator
• Usage of therapeutic tools such as vaginal dilators

Friction without enough natural lubrication can cause micro-tears in delicate vaginal tissue and even put you off activities that should feel good or be therapeutic (like consistent dilator use). A good lubricant removes that barrier.

Lubrication is especially important as a woman progresses through peri-menopause and menopause, when the intimate tissues can feel more dry.  Although we would argue lubrication can be used at any stage in life for optimised pleasure.

Vaginal moisturisers: restoring moisture

A vaginal moisturiser is designed to be used regularly (often every few days) to add moisture back into the tissues themselves.

This is most relevant in cases of:

• Vaginal dryness
• Menopause and perimenopause, when declining oestrogen thins and dries vaginal tissue (genitourinary syndrome of menopause, or GSM)
• Women simply wanting more comfort day-to-day

Just like other areas of our body require added moisture, particularly our faces, our delicate vaginal and vulval tissues also hugely benefit from a moisturising regime, and for some it can really be the difference between daily discomfort versus daily comfort.

Why the wrong product can cause harm

The vagina is lined with mucous membranes, not regular skin. Unlike the outer skin, mucous membranes don't have the same protective outer layer (the stratum corneum), which means they can be irritated, damaged, and can absorb synthetic chemicals far more easily than skin elsewhere on the body.

A poorly formulated lubricant or moisturiser can:

• Disrupt your natural vaginal pH, tipping the environment away from the acidic range that keeps protective bacteria (lactobacilli) thriving
• Irritate or damage the delicate mucosal tissue directly
• Feed opportunistic organisms like Candida (thrush)
• Introduce ingredients linked to broader health concerns with repeated use

Ingredients worth avoiding

These ingredients turn up in mainstream lubricants and moisturisers and are worth being cautious of:

• Glycerin (glycerine/glycerol): an irritant to mucous membranes. At low concentrations it can feed Candida species, contributing to thrush; at higher concentrations it can damage the mucosal tissue directly.
• Parabens e.g. Methylparaben: synthetic preservatives that mimic oestrogen, with some research raising concerns about a link to breast cancer.
• Propylene glycol: a penetration enhancer that can "pull" other chemicals into the skin, which is the opposite of what you want in a sensitive area.
• L-Arginine: used to increase blood flow to the tissues, can trigger outbreaks in people who carry genital herpes.
• Petroleum by-products (mineral oil, petrolatum/petroleum jelly, paraffin oil/wax): these coat the skin and prevent it from functioning normally, and can carry impurities of concern.
• Silicone oils e.g. Dimethicone: the subject of ongoing debate around long-term safety, similar to concerns raised about silicone breast implants.
• Grapefruit seed extract: marketed as a "natural" preservative, but testing has repeatedly found its antimicrobial effect actually comes from hidden synthetic chemicals, not the grapefruit extract itself.
• Parfums and fragrances: these are often chemically engineered, so can cause irritation and a disruption to the pH in this delicate environment.

Why pH balance matters so much

A healthy vagina sits at a mildly acidic pH, between 3.7 and 4.5. This acidity is maintained by lactobacilli, the "good" bacteria that produce acid and keep opportunistic bacteria and yeast in check.

Many mainstream lubricants and moisturisers are formulated at a neutral or alkaline pH, closer to that of semen or general skincare products, rather than the vagina itself. Regularly using a product that doesn't match your natural pH can nudge the environment away from that protective acidic range, potentially increasing the risk of imbalances like bacterial vaginosis (BV) or thrush over time.

This is why choosing a pH-balanced lubricant or moisturiser isn't just a nice-to-have; it's a protective choice for your vaginal microbiome and comfort levels.

What we recommend

For a lubricant, YES Water-based lubricant is a great choice, pH-balanced, certified organic, and formulated without glycerin, parabens, propylene glycol or the other ingredients listed above. It's perfectly safe to use with condoms too.

For ongoing moisture and comfort, YES Vaginal Moisturiser is designed to be used regularly, again pH-balanced and free from the irritants to watch out for.

For external, vulval use such as chafing, sensitivity, soreness and general vulval discomfort, Olive & Bee Intimate Cream is wonderful stuff. It's formulated with just two ingredients, antibacterial, anti-fungal and antioxidant rich olive oil*, and beeswax, which makes it exceptionally well tolerated, even for very sensitive skin, whilst being moisturising. *Olive oil also has a low comedogenic rating, hence it is less likely to block pores than other oils such as coconut oil.

A quick checklist for choosing lubricants and moisturisers carefully

• Check it's pH-balanced for vaginal use, not just "gentle" or "natural" as a general skincare claim
• Look for glycerin-free and paraben-free on the label
• Avoid propylene glycol, petroleum by-products, and silicone oils where possible
• Be wary of "natural" preservatives like grapefruit seed extract that may not be what they claim
• Choose the right type for the job: a lubricant for reducing friction for sexual activity and therapeutic pelvic tools, a moisturiser for dryness. Many women will need both. 

If you're prone to thrush or BV, ingredient choice matters even more, since certain ingredients can directly feed these imbalances.
