Yes Vaginal moisturiser applicators

How to use your YES vaginal moisturiser pre-filled applicators

Your YES vaginal moisturiser applicators come with detailed instructions for use. To summarise:

• The pre-filled applicators deliver the right amount of YES vaginal moisturiser to where it is needed— discreetly and hygienically.
• For best results apply regularly. Initially this may mean daily. But this may decrease to every second or third day within a week or so.
• The frequency of re-application depends on the severity of your dryness. The natural and pure ingredients in YES vaginal moisturiser means you can apply as much as you need to feel comfortable, with no dosage concerns. YES vaginal moisturiser is completely hormone free.

Osmolality – as defined by The YES YES Company Ltd

Osmolalityis the measure of dissolved particles per unit of water in a solution or plasma (also called the concentration). The osmolality of a lubricant is important because the epithelial (outer) layer of skin is constantly trying to maintain an equilibrium of osmolality (remember osmosis from school biology lessons?) between the skin cells and the lubricant on the outside wall of that cell.

• Osmosis is the process where water moves back and forth across cell membranes in response to the concentration of chemicals in the liquid (here we mean lubricant) on the outside of the cell. Osmosis tries to balance the concentration on both sides.
• When a lubricant has a higher osmolality than human cells or bodily fluids (like blood) it is called hyper-osmotic. When tissues are in contact with a hyper-osmotic lubricant they try to dilute the lubricant by releasing water. This can cause the cell to die as it becomes super concentrated and no longer able to function. The net result is the layer of cells break down and the body’s barrier to infection is compromised
• So hyper-osmotic lubricants can irritate the skin, cause the barrier layer of skin to be damaged and dehydrated and leave a mucous membrane (anal or vaginal) more susceptible to bacterial infections or STI contraction
• When a lubricant has a lower osmolality than human cells or bodily fluids (like blood) it is called hypo-osmotic. When tissues are in contact with a hypo-osmotic lubricant they try to pull water from the lubricant into the cell. This means that a slightly hypo-osmotic lubricant would rehydrate dry tissues, but an extremely hypo-osmotic lubricant could cause these cells to burst.

Therefore:

• a perfect anal lubricant’s osmolality would be iso-osmotic, meaning it would have identical osmotic pressure, or its concentration would be identical, to the tissues to which it is applied.
• a perfect vaginal lubricant’s osmolality would be hypo to iso-osmotic, meaning it would have similar osmotic pressure, or its concentration would be similar, to the tissues to which it is applied.
• a perfect vaginal moisturiser’s osmolality would be iso-osmotic, meaning it would have identical osmotic pressure, to vaginal tissues as it can be present in the vagina for extended periods, like 1-2 days, and will release water as needed.
• a perfect sperm friendly lubricant’s osmolality would be iso-osmotic with semen, which is slightly higher than typical human tissues.

An iso-osmotic lubricant, to most human tissues, would have an osmolality of 270-310 mOsm/kg as this encompasses the osmolality of human plasma.

YES vaginal moisturiser contains the preservative phenoxyethanol.
