Many women believe that glycerin increases their risk for yeast infections. However, there is limited data to support this fact. The most important factors that can alter the vaginal environment are two things called osmolality and pH.
So here’s the bottom line: If the osmolality and pH of your lubricant are acceptable and in-balance, the insignificant amount of glycerin in the product is inconsequential.
SYLK is an FDA Cleared product and each batch is reliably and consistently tested to ensure that it is in the acceptable ranges for osmolality and pH according to the World Health Organization.
