I am hesitant to try HYALO GYN Vaginal Hydrating Gel due to there is sodium hydroxide in it. Sodium hydroxide is lye, correct? That would really irritate vulva tissues.

HYALO GYN has been tested during the Clinical trial stage prior to the product being cleared by the US FDA. Clinical trials included studies to check for irritation. The sodium hydroxide is used to adjust the pH of the product during the manufacturing process.
