I think the Prevaleaf products are likely a good option for you. The Oasis Natural Daily Vaginal Moisturizer is paraben- and fragrance-free, as well as pH-balanced for the vaginal environment. Regular use is key to healthy tissues, which typically means less irritation.
Because you mention burning sensations after application, you might also like Soothe Natural Vaginal Soothing Cream. Like the moisturizer, it’s made with natural ingredients; it’s formulated for rapid absorption.
Your complaint of burning suggests the possibility of vulvodynia, a condition that results in burning pain with intercourse; anything that comes in contact with the area (near the opening of the vagina) can be experienced as burning or irritating. A careful pelvic exam can help determine if you have “simple” vaginal (or “urogenital”) atrophy or vulvodynia. If the former, the Prevaleaf products should be helpful and well-tolerated; other options might be explored if it’s the latter.
