Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Cocos Nucifera Fruit Extract comes from the meat of the coconut fruit. It is an emollient and skin conditioner with antioxidant properties.
Coconut fruit is naturally rich in amino acids, sugars, and nutrients including Vitamin C and small amounts of vitamin B. Malic acid can also be found in coconut fruit extract.
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.

As it ferments, it collects lactic acid, peptides, enzymes, and other bioactive metabolites to provide:
A 2023 review noted that probiotic fermentation ingredients like this one can enhance antioxidant capacity, reduce UV-induced oxidative damage, and support barrier function.
One clinical study from the same year showed a Lactobacillus ferment lysate significantly reduced transepidermal water loss and improved skin hydration.
Another review highlighted that topical Lactobacillus-based preparations can improve ceramide levels in the stratum corneum, support barrier integrity, and even help reduce S. aureus colonization in atopic dermatitis.
Why is this so cool?
Basically, your skin's outer layer works as a brick wall; skin cells are bricks and ceramides are the mortar holding it together. Moisture escapes, irritants get in, and your skin gets dry and reactive when ceramide levels drop. On top of that, "bad" skin bacteria S. aureus loves to move in when your barrier is weak to make inflammation and irritation worse.
So Lactobacillus ferment is basically patching the wall and evicting the troublemaker when it boosts ceramide production and help keep S. aureus in check.
On top of all this, it also acts as a mild antimicrobial preservative booster.
Just so you know, most studies focus on specific strains or the lysate form rather than this generic "Lactobacillus Ferment", so results can vary.
Though it's a promising ingredient, it doesn't have decades of robust clinical data behind it just yet.
Lactobacillus Ferment is generally considered safe for fungal-acne prone skin. The key thing to understand is that it comes from bacteria, not yeast or fungus.
Yeast-derived ferments (like galactomyces) have been shown to activate a protein that's linked to Malassezia-related skin issues whereas lactobacillus doesn't have that problem.
Its byproducts also don't contain the types of fatty acids (C11-24 chain lengths) that Malassezia feeds on.

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!
