When women in my practice have vaginal dryness or atrophy, I typically start by recommending a vaginal moisturizer. The key is to be faithful, using the moisturizer at least two times each week. Yes is the most popular vaginal moisturizer at MiddlesexMD; the fact that it's available in pre-filled applicators is definitely a plus for women who don't like the mess of other options!
I should also mention that a new oral medication for vaginal dryness or pain was approved by the FDA this summer. Non-hormonal, it's called Osphena and is available by prescription. Because it's oral, there's no mess! But you do need to make the consistent commitment, again, to regular use.
