Is vaginal estrogen the best treatment for vaginal dryness?

MENOPAUSE & SEXUAL HEALTH

Vaginal Estrogen Is First-Line, and It's Safe

What's really behind vaginal dryness after menopause, and how estrogen, moisturizers, laser and red light all fit together.

Dryness, burning, pain with sex, needing to pee all the time, UTIs that keep coming back, itching or irritation or other vaginitis symptoms? If any of that started around menopause, it has a name: genitourinary syndrome of menopause, or GSM. It affects roughly half or more of postmenopausal women, and unlike hot flashes, it doesn't fade with time. It gets worse the longer it goes untreated.

The cause is simple. The vagina, vulva, urethra and bladder are full of estrogen receptors. When estrogen drops, the vaginal lining thins, the tissue loses collagen and elasticity, and blood flow falls off. Since most natural lubrication is fluid that seeps through the vaginal wall from the vessels underneath, less blood flow means less moisture, both day to day and during sex.

Vaginal Estrogen Is First-Line Therapy

Because GSM is caused by missing estrogen, putting a small amount of estrogen back where it's needed treats the actual problem. It thickens the lining, restores blood flow and natural lubrication, and brings vaginal pH back to where it should be. The Menopause Society, ACOG and the American Urological Association all recommend it as first-line treatment, and it has decades of randomized trials behind it.

It also comes in several forms that work about equally well: a cream, a small vaginal tablet, a softgel insert, or a soft ring you replace every 3 months. Most women notice a difference within 2 to 4 weeks, with full benefit around 12 weeks. At these low doses very little estrogen reaches the bloodstream, and you don't need a progesterone to protect the uterus.

What about breast cancer?

Most of the fear around estrogen traces back to the Women's Health Initiative. But in that study, women who took estrogen alone, without a synthetic progestin, actually had fewer breast cancers than women on placebo, and that has held up over the more than 20 years of follow-up. Estrogen is not what drove the breast cancer headlines.

Furthermore, vaginal estrogen is a tiny fraction of that dose. Large studies following thousands of breast cancer survivors have not found more cancer recurrence or more breast cancer deaths in women who used it. In November 2025, the FDA announced it was removing the scary boxed warning from these products.

So yes, many women with a history of breast cancer can use vaginal estrogen. The one group we're more careful with is women currently taking an aromatase inhibitor, and for anyone with a cancer history, we make the plan together with your oncologist.

Vaginal DHEA, With or Without a Prescription

DHEA is a hormone precursor your body makes less of with age. Used as a nightly vaginal insert, the vaginal cells can convert it into testosterone and estrogen right where it's needed, without meaningfully raising hormone levels in the blood. The prescription version (prasterone) improved dryness and painful sex in placebo-controlled trials, and the bonus is the local testosterone, which supports the tissue too.

Over-the-counter vaginal DHEA suppositories are also available and can be a good option if cost or access is a barrier. Just know that OTC products aren't regulated the same way, so dose and quality vary from brand to brand. Ask us which ones we trust.

Moisturize Your Vagina Like You Moisturize Your Face

You wouldn't wait until your face was cracked and sore to put on moisturizer. Dr. Kelly Casperson, a board-certified urologist, makes this point all the time, and she's right: vaginal and vulvar tissue deserves the same daily care as the rest of your skin. A vaginal moisturizer used regularly, whether or not you're having sex, keeps tissue hydrated and comfortable. Hyaluronic acid is one of the best ingredients to look for.

Lubricant is a separate job. It's for sex, applied right before or during, to cut friction and the tiny tears that make sex painful. Silicone-based lube lasts longer than water-based (just not with silicone toys, which it can break down). Skip the warming, tingling and flavored products, which tend to irritate thinned tissue. Neither moisturizer nor lube replaces estrogen when atrophy is the cause, but both make a real difference alongside it.

Where Testosterone Comes In

Vaginal and vulvar tissue has testosterone receptors too, and testosterone matters for arousal, libido and tissue health. Right now there is no FDA-approved testosterone product for women in the U.S., even though several other countries have one. That may finally be changing. At the FDA's 2025 expert panel on menopause, doctors including Dr. Casperson pushed hard on this gap, and this September the FDA held a public workshop specifically on testosterone for menopausal women and signaled it's open to approving products designed for us.

In the meantime, a compounded testosterone applied vaginally is something we can talk through with you, based on your symptoms and labs.

What About Vaginal Laser?

CO2 and erbium lasers (and radiofrequency devices) deliver controlled heat to the vaginal wall to trigger a healing response and new collagen, a lot like laser resurfacing for skin. The research is limited. The best-designed trials comparing real laser to a sham treatment have been mixed, no device is FDA-approved for GSM, and a series usually runs $1,000 to $3,000 or more out of pocket, with yearly touch-ups.

Still, there are real women reporting real results, and I don't dismiss that. What I do wonder is how many of them went to laser because they believed they couldn't use vaginal estrogen, from a cancer history, an old warning label or something a provider told them years ago. If that's you, please ask your practitioner again. Laser isn't a bad option to try, but it's expensive and not well supported by evidence, and it shouldn't be the fallback for women who could safely be using estrogen.

Red Light Therapy at Home

Red and near-infrared light therapy (you'll also see it called photobiomodulation) works differently from laser. Instead of heat and controlled injury, the light is absorbed by the mitochondria in your cells, the tiny engines that make energy. In skin and wound-healing research, that boost has been shown to increase blood flow, support collagen production and calm inflammation, which are exactly the things that fade in vaginal tissue after menopause.

The research specific to vaginal use is early, with larger controlled trials only now getting underway. But it's gentle, low risk, and home devices cost a fraction of a laser series. It can also be used right alongside vaginal estrogen, so it doesn't have to be one or the other.

Estrogen Does More Than Fix Dryness

Estrogen keeps vaginal cells stocked with glycogen, a sugar that feeds lactobacilli, the good bacteria that keep the vagina acidic. When estrogen drops, glycogen drops, lactobacilli die off and vaginal pH rises. That less acidic environment is exactly where the bacteria behind UTIs and bacterial vaginosis (BV) move in. It's why so many women start getting UTIs or BV for the first time in their 50s, or suddenly can't shake them.

An active UTI or BV infection still needs to be treated directly, usually with antibiotics. But since low estrogen is often what set the stage in the first place, restoring it helps keep them from coming back. Vaginal estrogen is actually recommended in the urology guidelines to prevent recurrent UTIs in postmenopausal women.

Yeast infections are the exception. Yeast likes an estrogen-rich environment, so they're actually less common after menopause, and occasionally one shows up after starting vaginal estrogen. And a lot of what feels like "yeast" after menopause (itching, burning, irritation) turns out to be GSM itself. If you keep treating yourself for yeast and it keeps coming back, come see us before you buy another box.

If you've been told you can't use estrogen, or you've just been living with this because nobody asked, we'd love to talk through what makes sense for your body and your history.
