Vaginal moisturizers are applied directly to the vagina several times per week as a regular practice, regardless of whether or not you plan to have vaginal intercourse/ penetration. They’re designed to trap moisture, hydrate the vaginal tissues, and to lower pH levels in the vagina. (Vaginal pH is a measure of how acidic the inside of the vagina is. A lower pH level means it is more acidic and better able to control bacterial growth.) One of the best we’ve found is Luvena, which is free of parabens and glycerin and is available over-the-counter in many chain drugstores.(Parabens can act like a weak estrogen in the body, while glycerin can increase the risk of yeast infections.) Vitamin E oil is another vaginal moisturizer that is widely recommended: You can puncture the capsule and apply the oil to the inside of the vagina.
