Your skin is home to a community of microorganisms often called the skin microbiome. Keeping that environment balanced is part of what helps skin feel calm and comfortable. That is the idea behind probiotic-inspired skincare.
What is lactobacillus ferment?
Lactobacillus ferment is made by fermenting ingredients with lactobacillus, the same family of bacteria used to make yogurt. The finished ingredient does not contain live bacteria. Instead, it carries the beneficial byproducts of fermentation, which is why you will sometimes see these ingredients described as postbiotics.
How it can help your skin
- Supports a balanced, comfortable feel
- Helps skin hold on to hydration
- Pairs well with soothing ingredients for sensitive-feeling skin
Research on ferments in skincare is still growing, so think of them as a gentle, supportive ingredient rather than a quick fix.
Why it works well in a toner
A toner is the first leave-on step in your routine, so it touches clean skin directly. Pairing lactobacillus ferment with alpha-glucan oligosaccharide, centella asiatica, panthenol and hyaluronic acid creates a mild, hydrating layer that prepares skin for serum and cream.
Who it suits
Mild ferment-based toners suit most skin types, including skin that feels easily irritated. As with any new product, patch test on a small area first.
How to use: after cleansing, press a few drops into your skin or sweep with a cotton pad, morning and night. Follow with serum while skin is still slightly damp.
