Vaginal dryness, encompassed in the modern term genitourinary syndrome of menopause (GSM) affects up to 40% of menopausal women and up to 60% of postmenopausal breast cancer survivors.1,2 Premenopausal women also can have vulvovaginal dryness while breastfeeding (lactational amenorrhea) and while taking low-dose contraceptives.3 Vaginal moisturizers and lubricants are the first-line treatment options for vaginal dryness, dyspareunia, and GSM.4,5 In fact, approximately two-thirds of women have reported using a vaginal lubricant in their lifetime.6 Despite such ubiquitous use, many health care providers and patients have questions about the difference between vaginal moisturizers and lubricants and how to best choose a product.

Vaginal moisturizers

Vaginal moisturizers are designed to rehydrate the vaginal epithelium. Much like facial or skin moisturizers, they are intended to be applied regularly, every 2 to 3 days, but may be applied more often depending on the severity of symptoms. Vaginal moisturizers work by increasing the fluid content of the vaginal tissue and by lowering the vaginal pH to mimic that of natural vaginal secretions. Vaginal moisturizers are typically water based and use polymers to hydrate tissues.7 They change cell morphology but do not change vaginal maturation, indicating that they bring water to the tissue but do not shift the balance between superficial and basal cells and do not increase vaginal epithelial thickness as seen with vaginal estrogen.8 Vaginal moisturizers also have been found to be a safe alternative to vaginal estrogen therapy and may improve markers of vaginal health, including vaginal moisture, vaginal fluid volume, vaginal elasticity, and premenopausal pH.9 Commercially available vaginal moisturizers have been shown to be as effective as vaginal estrogens in reducing vaginal symptoms such as itching, irritation, and dyspareunia, but some caution should be taken when interpreting these results as neither vaginal moisturizer nor vaginal estrogen tablet were more effective than placebo in a recent randomized controlled trial.10,11 Small studies on hyaluronic acid have shown efficacy for the treatment of vaginal dryness.12,13 Hyaluronic acid is commercially available as a vaginal suppository ovule and as a liquid. It may also be obtained from a reliable compounding pharmacy. Vaginal suppository ovules may be a preferable formulation for women who find the liquids messy or cumbersome to apply.

Lubricants

Lubricants differ from vaginal moisturizers because they are specifically designed to be used during intercourse to provide short-term relief from vaginal dryness. They may be water-, silicone-, mineral oil-, or plant oil-based. The use of water- and silicone-based lubricants is associated with high satisfaction for intercourse as well as masturbation.14 These products may be particularly beneficial to women whose chief complaint is dyspareunia. In fact, women with dyspareunia report more lubricant use than women without dyspareunia, and the most common reason for lubricant use among these women was to reduce or alleviate pain.15 Overall, women both with and without dyspareunia have a positive perception regarding lubricant use and prefer sexual intercourse that feels more “wet,” and women in their forties have the most positive perception about lubricant use at the time of intercourse compared with other age groups.16 Furthermore, the World Health Organization (WHO) recommends that condom-compatible lubricants be used with condoms for menopausal and postmenopausal women.17 Both water-based and silicone-based lubricants may be used with latex condoms, while oil-based lubricants should be avoided as they can degrade the latex condom. While vaginal moisturizers and lubricants technically differ based on use, patients may use one product for both purposes, and some products are marketed as both a moisturizer and lubricant.
