Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types.
Piper Nigrum (Black Pepper) Seed Extract is derived from black peppercorns and contains piperine and volatile oils; it is used in skincare for its warming, circulation-stimulating and antioxidant properties, and is sometimes included for purported absorption-enhancing or invigorating effects.
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 |
|---|---|---|
| Mild transient irritation or stinging | Rare | Occasional on sensitive or compromised skin |
| Allergic contact dermatitis | Very rare | Sugar-derived humectants are generally low-sensitizing |
| Contact allergy or sensitization | Very rare | Sugar alcohol-based humectants have a low reported sensitization potential. |
| Transient skin tightness or dryness | Uncommon | May occur in low-humidity environments where the ingredient can draw moisture from deeper skin layers if not sealed with an occlusive. |
| Mild irritation, redness, or stinging | Uncommon | Often related to other formulation components or compromised skin barrier rather than hyaluronic acid itself. |
| Hypersensitivity reactions with injectable forms | Rare | Pertains to dermal filler use rather than topical application; includes swelling or nodule formation. |
| Skin irritation / warming sensation | Common | Piperine and aromatic compounds can cause transient tingling, warmth, or stinging, especially at higher concentrations. |
| Erythema (redness) | Uncommon | May occur on sensitive or compromised skin due to its rubefacient action. |
| Photosensitivity | Very rare | Limited reports; some Piper-derived constituents may theoretically increase sun sensitivity. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Mild transient flushing or redness | Uncommon | More likely at higher concentrations or in sensitive skin; usually subsides quickly. |
| Tingling, stinging, or burning sensation | Uncommon | Often associated with higher percentages or compromised barrier. |
| Contact irritation or itching | Rare | Generally dose-dependent and resolves with discontinuation. |

| Ingredient | What it does |
|---|---|
| Xylitylglucoside Humectant / moisturizer | Xylitylglucoside is a sugar-derived humectant, typically used in combination with anhydroxylitol and xylitol, that helps attract and retain water in the skin and supports the skin barrier. It is valued for its skin-hydrating and moisturizing properties in cosmetic formulations. |
| Anhydroxylitol And Xylitol Humectant / moisturizing agent | Anhydroxylitol and Xylitol is a sugar-derived blend used as a humectant that helps bind water in the skin and support the skin's natural moisturizing factor and barrier function. It is typically combined with xylitylglucoside in hydration-focused formulations. |
| Hyaluronic Acid Key active Humectant / hydrating agent | Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types. |
| Piper Nigrum (Black Pepper) Seed Extract Key active Skin-conditioning / stimulating extract | Piper Nigrum (Black Pepper) Seed Extract is derived from black peppercorns and contains piperine and volatile oils; it is used in skincare for its warming, circulation-stimulating and antioxidant properties, and is sometimes included for purported absorption-enhancing or invigorating effects. |
| 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. |
| 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%. |
| Xanthan Gum Thickener/stabilizer | Xanthan gum is a polysaccharide produced by bacterial fermentation, used in skincare as a thickening, gelling, and emulsion-stabilizing agent. It improves product texture and suspension of ingredients without contributing active treatment effects. |
| 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. |
| Ethylhexylglycerin Preservative booster / skin-conditioning agent | Ethylhexylglycerin is a multifunctional glyceryl ether used in cosmetics primarily as a preservative-enhancing agent and emollient, often paired with phenoxyethanol to broaden antimicrobial efficacy. It also acts as a deodorizing agent and humectant in skincare formulations. |
| 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. |
