Nobody wants to talk about preservatives — but somebody has to. Here’s the truth: if your skincare product contains water, it needs a preservative. Full stop. Without one, you’re essentially leaving a warm, wet environment open for bacteria, mold, and yeast to move in and set up shop. Germall Plus (DMDM Hydantoin and Iodopropynyl Butylcarbamate) is one of the reliable, broad-spectrum options that keeps water-based formulas safe from the moment you open the lid to the very last drop.
It’s not glamorous. It doesn’t have an origin story involving ancient Egyptians or a mountain in Morocco. But it does something genuinely important — it keeps the products you love from becoming something that could hurt your skin. Effective against bacteria, yeast, and mold, it’s been a trusted tool in professional formulation for decades and is the quiet reason your lotion still smells right six months later.
Best Uses: Lotions, creams, and body butters containing water; facial serums and toners; any leave-on or rinse-off product where water is present.
