Not all lubricants are created equal, and reading the fine print on the bottle can tell you why. It holds one of the most important clues to how a product will actually feel and behave inside your body.
The key word to know: osmolality.
Iso-osmotic means a product's concentration matches your body's natural fluids, so your vaginal lining isn't disrupted. That match supports healthy pH, lasting moisture, and a balanced environment. (Psst: all Good Clean Love products are proven to be iso-osmotic.)
Hyperosmolar means the opposite. A hyperosmolar product pulls moisture out of your vaginal lining, which can cause irritation and create an environment where harmful bacteria thrive. In a recent clinical study, women using a hyperosmolar lubricant saw increased BV risk over time, while women using an iso-osmotic lubricant didn't.
Consider this your microbiome cheat sheet: what to look for on a product label, and why it matters for what's supportive versus what works against you.
