Ingredients higher up in an ingredient list are typically present in a larger amount. Bacillus Ferment is created by fermenting Bacillus bacteria with yeast extract and carbohydrates. It acts as a humectant and, depending on the strain, can also provide gentle enzymatic exfoliation. Depending on the strain and formulation, it may also act as a peptide, probiotic, or prebiotic. Certain strains of Bacillus Ferment help support the skin’s microbiome, soothe inflammation, and promote barrier repair and hydration. It’s typically used at 0.5-5% concentration, either for mild exfoliation or to improve overall skin health and texture. Some studies show that Bacillus species can inhibit certain plant fungi (such as Fusarium verticillioides and Fusarium oxysporum) used in agricultural biocontrol. However, these are filamentous molds, not the yeast (Malassezia furfur) responsible for fungal acne. At this time, there are no studies showing that Bacillus Ferment inhibits Malassezia or that it has been tested on human skin or in cosmetic formulations. Because of this lack of cosmetic and dermatological research, we list Bacillus Ferment as not safe for fungal acne as a precaution. However, it may not trigger breakouts for everyone. Cetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product. Its main roles are: Though it has "alcohol" in the name, it is not related to denatured alcohol or ethyl alcohol. The FDA allows products labeled "alcohol-free" to have fatty alcohols. This ingredient may not be fungal acne safe. It is a primary fatty alcohol with a chain length above 12 carbons. A study from 2019 show Malassezia can feed on fatty alcohols in this range, so it may trigger fungal acne in those prone to it. Coco-Caprylate is a lightweight emollient made by combining coconut-derived fatty alcohols (caprylic and capric acid). Its primary role in formulas is as a skin-softening emollient with excellent spreadability (it's considered a plant-based alternative to silicone oils like dimethicone). This ingredient is considered safe for use and concentrations range from 0.5-62%. Caprylic and capric fall outside the C11-24 range that Malassezia feeds on, and a 2020 study found caprylic acid disrupted Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%. Ferulic Acid is a plant based antioxidant that can be naturally found in the cell walls of grains like rice, oats, and corn. It has antioxidant and antimicrobial properties, and has the ability to boost the performance of other antioxidants as well. A well-known study found that adding Ferulic Acid to a solution of Vitamins C and E doubled the photoprotection of skin. This is why you'll often see it paired with Vitamin C or Vitamin E serums rather than sold on its own. A 2025 review of 18 human studies found that using Ferulic Acid (0.5-1%) daily for o
