Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Lactobacillus is the INCI name for the live, whole lactic bacteria culture itself and is classified as a skin conditioning agent.
It is the same genus of probiotic that you can find in yogurt or fermented foods and it shows up at low levels naturally on human skin.
This ingredient is more of a microbiome agent rather than an active; it helps rebalance the skin's microbial community.
The bacteria and their metabolites produce lactic acid and other antimicrobial compounds that crowd out the "bad bacteria". Research on Lactobacillus strains shows activity against pathogens and acne-causing bacteria.
One strain, Lactobacillus plantarum, has also been shown to boost collagen synthesis and lower melanin synthesis in lab and clinical observation.
The most eye-catching data comes from acne research, a topical cream with live lactobacilli was well-tolerated and improved skin hydration by 37.3% after 14 days of use and 45.6% after 28 days.
Sources for this ingredient are usually fermented substrates like dairy, soy, or rice.
In general, this is a low-irritation and well-tolerated ingredient that plays nice with most of your routine.
One thing to keep in mind is that live bacteria are hard to keep alive inside of a skincare product. They struggle to survive on the shelf and don't get along with the preservatives that stop products from spoiling.
That's why you'll see ferment and postbiotic forms instead, like Lactobacillus Ferment or Lactobacillus Ferment Lysate.
There isn't a fixed percentage for this ingredient since it is dosed by strain and viable count.
On the fungal acne front: Lactobacillus is a bacterium (not a fungus). The whole culture contains no fatty acids, esters, or oils that Malassezia can feed on so it is considered fungal acne safe.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
