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%.
Saccharum Officinarum (Sugar Cane) Extract is derived from sugar cane and is used in skincare as a humectant and as a source of glycolic acid and other alpha hydroxy acids that provide mild exfoliating and skin-conditioning effects. It is commonly marketed as a natural AHA ingredient, though the actual acid concentration in extracts is often low and variable.
Vaccinium Myrtillus (Bilberry) Fruit Extract is a botanical extract rich in anthocyanins and other polyphenols, used in skincare for its antioxidant and skin-conditioning properties. It may help protect skin from oxidative stress and support a more even, soothed complexion.
Acer Saccharinum (Sugar Maple) Extract is a plant-derived ingredient containing natural alpha-hydroxy acids (notably malic acid) and is used in cosmetics for mild chemical exfoliation and skin conditioning. It is often marketed as a botanical AHA source to support smoother skin texture.
Citrus Limon (Lemon) Fruit Extract is derived from lemon fruit and contains citric acid, vitamin C, and flavonoids; it is used in skincare for its mild astringent, antioxidant, and brightening properties. It can act as a natural exfoliant and fragrance component.
Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation or stinging | Common | More likely at higher concentrations or on compromised/sensitive skin |
| Allergic contact dermatitis | Uncommon | Recognized contact allergen; confirmed via patch testing |
| Irritant contact dermatitis | Uncommon | Non-allergic irritation, often dose-dependent |
| Worsening of pre-existing eczema or barrier-impaired skin | Rare | Penetration-enhancing effect may increase reactivity |
| Systemic toxicity from topical use | Very rare | Reported mainly with extensive application on broken skin, especially in infants or burn patients |
| 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. |
| Mild transient skin irritation | Rare | Occasional stinging or redness, more likely on compromised or sensitive skin. |
| Eye irritation | Uncommon | Can cause stinging or irritation if products contact the eyes. |
| 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. |

| Ingredient | What it does |
|---|---|
| Propylene Glycol Humectant / solvent | Propylene glycol is a small glycol molecule widely used in skincare as a humectant, solvent, and penetration enhancer that helps attract water and dissolve other ingredients. It is considered a base/formulation ingredient rather than a therapeutic active. |
| 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%. |
| Carbomer Thickener / gelling agent | Carbomer is a synthetic high-molecular-weight polymer of acrylic acid used to thicken, stabilize, and control the viscosity of gels, creams, and lotions. It functions as a formulation aid rather than a therapeutic active. |
| 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. |
| Saccharum Officinarum (Sugar Cane) Extract Key active Humectant / natural exfoliant (AHA source) | Saccharum Officinarum (Sugar Cane) Extract is derived from sugar cane and is used in skincare as a humectant and as a source of glycolic acid and other alpha hydroxy acids that provide mild exfoliating and skin-conditioning effects. It is commonly marketed as a natural AHA ingredient, though the actual acid concentration in extracts is often low and variable. |
| Vaccinium Myrtillus (Bilberry) Fruit Extract Key active Antioxidant | Vaccinium Myrtillus (Bilberry) Fruit Extract is a botanical extract rich in anthocyanins and other polyphenols, used in skincare for its antioxidant and skin-conditioning properties. It may help protect skin from oxidative stress and support a more even, soothed complexion. |
| Citrus Aurantium Dulcis (Orange) Fruit Extract Antioxidant / skin conditioning | Citrus Aurantium Dulcis (Orange) Fruit Extract is derived from sweet orange fruit and is used in skincare for its vitamin C content, antioxidant flavonoids, and skin-conditioning and natural fragrance properties. It is typically included as a supportive botanical ingredient rather than a primary clinical active. |
| Acer Saccharinum (Sugar Maple) Extract Key active Skin conditioning / exfoliant | Acer Saccharinum (Sugar Maple) Extract is a plant-derived ingredient containing natural alpha-hydroxy acids (notably malic acid) and is used in cosmetics for mild chemical exfoliation and skin conditioning. It is often marketed as a botanical AHA source to support smoother skin texture. |
| Citrus Limon (Lemon) Fruit Extract Key active Astringent/brightening botanical extract | Citrus Limon (Lemon) Fruit Extract is derived from lemon fruit and contains citric acid, vitamin C, and flavonoids; it is used in skincare for its mild astringent, antioxidant, and brightening properties.

| Salicylic Acid Key active Beta-hydroxy acid (BHA) exfoliant / keratolytic | Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin. |
| 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. |
| Peg-40 Hydrogenated Castor Oil Solubilizer/emulsifier | PEG-40 Hydrogenated Castor Oil is a nonionic surfactant derived from hydrogenated castor oil reacted with ethylene oxide, widely used to dissolve fragrances and oils into water-based formulations and to stabilize emulsions.
