Understanding osmolality
When browsing product descriptions for vaginal moisturisers, you may have come across the term osmolality. But what does it actually mean, and why is it important for your vaginal health? Osmolality refers to the concentration of dissolved particles (osmoles) in a solution. In the context of vaginal moisturisers, it measures how concentrated the ingredients are in relation to the body's own tissues.
This matters because vaginal tissues are particularly delicate - especially when dry, atrophic, or inflamed. If a moisturiser’s osmolality is too high (hyper-osmotic), it can draw water out of the cells, causing irritation or even tissue damage. If it’s too low (hypo-osmotic), it can flood cells with water, also leading to discomfort. The ideal vaginal moisturiser should be iso-osmotic - meaning it closely matches the natural osmolality of vaginal tissues.
YES VM vaginal moisturiser
YES VM vaginal moisturiser is formulated to be iso-osmotic. This ensures it rehydrates dry tissues without disrupting the natural fluid balance of the cells. Unlike strongly hyper- or hypo-osmotic products, YES VM vaginal moisturiser works in harmony with the body’s tissues, delivering moisture where it's needed without causing harm.
In addition to being iso-osmotic, YES VM vaginal moisturiser is also pH-balanced to match the normal vaginal environment, which typically ranges from pH 3.7-4.5. Maintaining this slightly acidic pH is crucial for supporting a healthy vaginal microbiome and protecting against infections.
Unlike lubricants, which are typically used for short-term relief during intimacy, vaginal moisturisers are designed to remain in contact with vaginal tissues for longer periods - often 1 to 3 days. Because of this prolonged contact, it is essential that they are formulated to be gentle, non-irritating, and physiologically compatible.
They typically have a lower osmolality to release moisture more rapidly. YES VM vaginal moisturiser is iso-osmotic, supporting sustained hydration. YES WB water-based is slightly hypo-osmotic, enabling fast rehydration and lubrication.
- Use YES VM vaginal moisturiser for long-term comfort and tissue repair
- Use YES WB water-based lubricant when you need fast, effective lubrication for intercourse or vaginal devices
-
Use YES OB oil-based lubricant for soothing the vulva externally
When would you use a vaginal moisturiser?
Vaginal dryness is a common symptom, especially during perimenopause and menopause, affecting up to 80% of women due to declining oestrogen levels. It can lead to discomfort, irritation, and dypareunia (painful sex).
Other conditions that may cause or worsen vaginal dryness include vestibulodynia, vulvodynia, Lichen Sclerosus and certain cancer treatments. Postpartum and breastfeeding hormonal shifts may aslo impact vaginal dryness.
For many, regular use of a non-hormonal, iso-osmotic, pH-balanced vaginal moisturiser can provide significant relief and support overall vaginal health.
How does YES VM vaginal moisturiser work?
YES VM vaginal moisturiser is designed to hydrate the vaginal walls using natural hydrocolloids (plant-based gums) that are bio-adhesive. These ingredients gently adhere to dry mucosal tissues and gradually release water where needed. Over time and with regular use, YES VM vaginal moisturiser can help restore moisture, soothe irritation, and rebalance the vaginal pH, creating a more comfortable and protective environment.
What is the difference between a lubricant and a vaginal moisturiser?
Vaginal moisturisers, such as like YES VM vaginal moisturiser are designed for long-term hydration. They slowly release water over 1-3 days and are ideal for addressing ongoing dryness and tissue fragility.
Lubricants, such as YES WB water-based and YES OB oil-based lubricants provide immediate moisture and are intended for short-term use during intimacy, dilation therapy or vaginal insertion.
