Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
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. |
| Contact irritation or mild redness | Uncommon | Generally mild and transient in sensitive individuals. |
| Allergic contact dermatitis | Rare | Possible in people with milk protein sensitivity or allergy. |
| Acneiform breakouts | Rare | Anecdotally reported; dairy-derived proteins occasionally implicated. |
| Skin dryness | Common | Strips natural oils, leading to dehydration with frequent or prolonged use. |
| Irritation and stinging | Common | Especially on broken, sensitive, or compromised skin. |
| Contact dermatitis | Uncommon | Can present as irritant or, less often, allergic dermatitis. |
| Disruption of skin barrier | Uncommon | Repeated exposure may impair the lipid barrier function. |
| Allergic contact sensitization | Rare | True allergy to isopropyl alcohol is uncommon but documented. |
| Systemic toxicity from absorption | Very rare | Reported mainly with large-surface or occluded exposure, not typical topical cosmetic use. |
| Mild stinging or tingling on application | Common | Transient, often more noticeable at higher concentrations or on compromised skin. |
| Skin dryness or flaking | Common | Result of accelerated exfoliation, especially when overused. |
| Erythema (redness) | Common | Usually temporary; more pronounced with higher strengths. |
| Increased photosensitivity | Common | AHAs heighten UV sensitivity; daily sunscreen is advised. |
| Irritant contact dermatitis | Uncommon | Burning, itching, or persistent redness, often from overuse or high concentration. |
| Post-inflammatory hyperpigmentation | Uncommon | More likely in darker skin tones following irritation. |
| Chemical burn or blistering | Rare | Associated with high-concentration peels or prolonged contact. |

| 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. |
| Whey Protein Skin-conditioning / moisturizing agent | Whey protein is a milk-derived protein complex used in skincare for its moisturizing and skin-conditioning properties, and is sometimes promoted for antioxidant and barrier-supporting effects. Evidence for significant topical actives is limited, and it functions largely as a conditioning additive. |
| Isopropyl Alcohol Solvent/antimicrobial | Isopropyl alcohol is a clear, volatile solvent used in skincare and cosmetic formulations as a solvent, antiseptic, and to aid rapid drying. It dissolves oils and other ingredients and is commonly found in toners, astringents, and disinfecting products. |
| Lactic Acid Key active Chemical exfoliant (AHA) | Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations. |
| Aloe Barbadensis Leaf Extract Soothing/moisturizing agent | Aloe Barbadensis Leaf Extract is derived from the aloe vera plant and is used in skincare for its hydrating, soothing, and mild anti-inflammatory properties. It is commonly included as a supportive base ingredient rather than a primary treatment active. |
| Propanediol Humectant/solvent | Propanediol is a plant-derived glycol used in skincare as a humectant, solvent, and penetration enhancer that improves moisturization and the spreadability of formulations. It also helps solubilize other ingredients and can boost the efficacy of certain actives. |
| 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. |
| Niacinamide Key active Cell-communicating / barrier-repair active | Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%. |
| Sodium Lactate Humectant / NMF component | Sodium lactate is the sodium salt of lactic acid and a key component of skin's natural moisturizing factor (NMF), used to hydrate the skin and buffer formulation pH. It also has mild exfoliating and humectant properties that help maintain skin moisture and barrier function. |
| Sodium Gluconate Chelating agent / skin-conditioning | Sodium gluconate is the sodium salt of gluconic acid used in skincare primarily as a chelating agent to bind metal ions and stabilize formulations, with secondary humectant and skin-conditioning properties. It is generally considered a base/formulation ingredient rather than an active treatment. |
