Lactic acid in lubricant: Why it is so important for vaginal health

When it comes to intimate health, the right ingredients play a crucial role. One of the most important active ingredients is lactic acid —but why? In this article, we explain how lactic acid supports the vaginal flora, can prevent infections , and why it shouldn't be missing from your lubricant.

What is lactic acid and why does your vagina need it?

The healthy vaginal flora is a small ecosystem of good bacteria, primarily lactobacilli . These bacteria produce lactic acid, which maintains the vaginal pH in the slightly acidic range (approximately 3.8–4.5). A stable pH is important because it inhibits the growth of harmful bacteria and fungi, thus reducing the risk of infection.

However, stress, hormonal changes (e.g., during menstruation, hormonal contraception, pregnancy, or menopause), and the use of irritating products can disrupt this balance. A lubricant containing lactic acid can help maintain the vagina's natural protective barrier .

The benefits of lactic acid in lubricant

Supports healthy vaginal flora

Lactic acid helps maintain the balance of the vaginal flora and thus protects against bacterial imbalances.

Protects against infections

A stable pH level can reduce the risk of bacterial vaginosis, yeast infections and other unpleasant conditions.

Gentle care for sensitive skin

Lactic acid not only balances the pH but also moisturizes – perfect for a lubricant that nourishes rather than irritates.
