how to shop for a lubricant
i love that you asked about how to discern the best products amidst a sea of great marketing and package design. i have learned that established brands, and prominent positioning in the drug store aisle does not always equal great ingredients.
generally, i advise women — with any purchase — to always turn the package around and read the list of ingredients. however, when it comes to lubricants, this is not such an easy task.
that’s because, even though in 2012, the world health organization (who)
issued an advisory highlighting concerns about ph levels and the osmolality of certain lubricants. osmolality measures the concentration of dissolved particles per unit of water — basically, how hard your vagina has to work to maintain equilibrium with the lubricant. unfortunately, ph and osmolality levels are not included in lubricant package design. it takes a well-informed consumer to know which product is less likely to disrupt the natural ph level of their vagina.
the who recommends a lubricant with a ph of, or close to, 4.5 and osmolality of less than 1200 mosm/kg, which are the same as the vaginal tissue naturally. this is important because if a lubricant has a higher osmolality than the cells of the body, the vaginal tissue releases its own moisture in an attempt to reach homeostasis with the lubricant. so instead of lubricating the vaginal tissue, it actually dries it out. this can put women at greater risk of infection, and present a challenge for those already dealing with dryness.
