Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration.
Lactobacillus Ferment is a postbiotic ingredient produced by the fermentation of Lactobacillus bacteria, used in skincare for its soothing, barrier-supporting, and antioxidant properties. It may help balance the skin microbiome and reduce visible signs of irritation.
Saccharomyces Ferment is a yeast-derived fermentation filtrate used in skincare for its content of amino acids, vitamins, minerals, and peptides that support hydration, barrier function, and a brightening or soothing effect. It is valued as a multifunctional bioactive often featured in 'ferment' or essence-type formulations.
Bacillus Coagulans Ferment is a postbiotic ingredient produced by fermentation with the lactic-acid-forming bacterium Bacillus coagulans, used in skincare to support the skin microbiome and provide soothing, conditioning, and antioxidant benefits. It contains metabolites such as peptides, organic acids, and exopolysaccharides rather than live bacteria in most cosmetic applications.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Mild transient stinging or tingling | Common | Brief sensation on application, particularly at higher concentrations or on compromised skin. |
| Mild erythema (redness) | Uncommon | Usually temporary and resolves shortly after use. |
| Dryness or flaking | Uncommon | Related to its exfoliating action, more likely with frequent use. |
| Increased sun sensitivity | Uncommon | PHAs are generally less photosensitizing than AHAs, but sunscreen is still advised. |
| Allergic contact dermatitis | Rare | Hypersensitivity reactions are infrequently reported. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Mild transient skin irritation or stinging | Rare | Typically minor and self-limiting, more likely on compromised skin |
| Skin irritation | Uncommon | More likely with high concentrations or improperly buffered formulas. |
| Chemical burns | Rare | Associated with concentrated solutions, not properly formulated finished products. |
| Eye irritation | Uncommon | Can occur on accidental contact with products containing it. |
| Dryness or stinging | Rare | Possible on sensitive or compromised skin. |

| Ingredient | What it does |
|---|---|
| Water Solvent/vehicle | Water is the most common base ingredient in cosmetic formulations, serving as a solvent that dissolves other ingredients and forms the bulk of emulsions and aqueous solutions. It is generally considered safe and non-irritating. |
| Gluconolactone Key active Polyhydroxy acid (PHA) exfoliant/humectant | Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Butylene Glycol Humectant / solvent | Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| Xylitol Humectant / moisturizer | Xylitol is a sugar alcohol used in topical formulations as a humectant that helps attract and retain moisture in the skin, and it may support the skin's microbiome and barrier function. It is generally well tolerated and considered safe for topical use. |
| Sodium Hydroxide pH adjuster | Sodium hydroxide (lye) is a strong alkaline compound used in small amounts to adjust and stabilize the pH of cosmetic formulations. At regulated low concentrations in finished products it is considered safe, though it is corrosive in concentrated form. |
| Lactobacillus Ferment Key active Probiotic-derived skin conditioning/soothing agent | Lactobacillus Ferment is a postbiotic ingredient produced by the fermentation of Lactobacillus bacteria, used in skincare for its soothing, barrier-supporting, and antioxidant properties. It may help balance the skin microbiome and reduce visible signs of irritation. |
| Saccharomyces Ferment Key active Skin-conditioning / fermentation-derived bioactive | Saccharomyces Ferment is a yeast-derived fermentation filtrate used in skincare for its content of amino acids, vitamins, minerals, and peptides that support hydration, barrier function, and a brightening or soothing effect. It is valued as a multifunctional bioactive often featured in 'ferment' or essence-type formulations. |
| Bacillus Coagulans Ferment Key active Probiotic-derived ferment / skin-conditioning agent | Bacillus Coagulans Ferment is a postbiotic ingredient produced by fermentation with the lactic-acid-forming bacterium Bacillus coagulans, used in skincare to support the skin microbiome and provide soothing, conditioning, and antioxidant benefits. It contains metabolites such as peptides, organic acids, and exopolysaccharides rather than live bacteria in most cosmetic applications. |
| Inulin Prebiotic / skin-conditioning agent | Inulin is a plant-derived fructan polysaccharide used in skincare as a prebiotic to support the skin's microbiome and as a mild humectant and texture-enhancing ingredient. It is generally considered well tolerated and is most often found in microbiome-targeted or moisturizing formulations. |
| Phenoxyethanol Preservative | Phenoxyethanol is a widely used broad-spectrum preservative that protects cosmetic and skincare formulations from bacterial and fungal contamination. It is typically used at concentrations up to 1% and serves as a formulation/base ingredient rather than an active treatment. |
| Sodium Benzoate Preservative | Sodium benzoate is a salt of benzoic acid used as a preservative in cosmetic and skincare formulations to inhibit the growth of bacteria, yeast, and fungi, particularly in acidic products. It is most effective at a pH below 5. |
| Potassium Sorbate Preservative | Potassium sorbate is the potassium salt of sorbic acid, used as a mild preservative to inhibit mold, yeast, and some bacterial growth in cosmetic formulations. It is most effective at acidic pH and is often combined with other preservatives for broad-spectrum protection. |
