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 |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| 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. |
| Allergic contact dermatitis | Uncommon | A notable cause of allergic contact dermatitis, often attributed to impurities (amidoamine, 3-dimethylaminopropylamine) rather than the molecule itself; named Allergen of the Year in 2004. |
| Skin or eye irritation | Uncommon | Mild stinging or irritation, more likely in concentrated or rinse-off products and around the eyes. |
| Cross-reactivity with related surfactants | Rare | Patch-test reactions may overlap with chemically related amphoteric or amine-containing surfactants. |
| Mild skin or eye irritation | Uncommon | More likely at higher concentrations or with prolonged contact; generally well tolerated. |
| Dryness or disruption of skin barrier | Uncommon | Possible with frequent use, though milder than stronger sulfate surfactants. |
| Dryness or stinging | Rare | More likely on already compromised or very sensitive skin. |
| Skin irritation | Rare | Mild transient irritation possible, generally related to overall formulation rather than the polymer itself. |
| Eye irritation | Rare | Possible stinging if product accidentally enters the eyes. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
| Ingredient | What it does |
|---|---|
| Aqua Solvent / vehicle | Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery. |
| 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. |
| Cocamidopropyl Betaine Surfactant / foaming cleanser | Cocamidopropyl Betaine is an amphoteric surfactant derived from coconut oil and dimethylaminopropylamine, used in cleansers, shampoos, and body washes to provide gentle foaming, viscosity, and to reduce the harshness of stronger anionic surfactants. It is widely regarded as mild but is a recognized contact allergen. |
| Disodium Laureth Sulfosuccinate Mild surfactant/cleansing agent | Disodium Laureth Sulfosuccinate is a gentle anionic surfactant derived from sulfosuccinic acid, used in cleansers and shampoos to produce foam and remove dirt and oil. It is valued for being milder and less irritating than harsher sulfates like sodium lauryl sulfate. |
| Sodium Cocoamphoacetate Mild amphoteric surfactant/cleansing agent | Sodium cocoamphoacetate is a coconut-derived amphoteric surfactant used in cleansers, shampoos, and body washes to provide gentle cleansing, foaming, and to reduce the irritation potential of harsher anionic surfactants. It is valued for its mildness and is commonly found in baby and sensitive-skin formulations. |
| Acrylates/C10-30 Alkyl Acrylate Crosspolymer Rheology modifier / emulsion stabilizer | Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic crosslinked acrylic polymer used to thicken, gel, and stabilize emulsions in skincare and cosmetic formulations. It helps suspend ingredients and provides a smooth, consistent texture without acting as a treatment active. |
| Sodium Chloride Thickener / viscosity adjuster | Sodium chloride (table salt) is commonly used in cosmetics as a thickening and viscosity-control agent, particularly in surfactant-based cleansers, and also acts as a mild abrasive in scrubs. It is generally well tolerated and considered a formulation ingredient rather than a treatment active. |
| 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. |
| Citric Acid pH adjuster / AHA exfoliant | Citric acid is an alpha-hydroxy acid derived from citrus fruits, used primarily to adjust and buffer formulation pH and as a chelating agent, and at higher concentrations as a mild chemical exfoliant. It can promote surface cell turnover and is sometimes included in antioxidant or brightening products. |
| Parfum Fragrance | Parfum (fragrance) is a blend of aromatic compounds added to cosmetic products to impart a pleasant scent or mask the base odor of other ingredients. It serves a sensory/formulation purpose rather than providing any skin benefit. |
| Panthenol Humectant / skin-conditioning agent | Panthenol (provitamin B5) is converted to pantothenic acid in the skin, where it acts as a humectant and helps support skin barrier function and hydration. It is also used for its soothing and mild anti-inflammatory properties in topical formulations. |
| 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%. |
| Linalool Fragrance/masking agent | Linalool is a naturally occurring terpene alcohol found in lavender, coriander, and many other plants, used in skincare primarily as a fragrance component. It readily oxidizes upon exposure to air, forming sensitizing hydroperoxides. |
| Hydroxycitronellal Fragrance ingredient | Hydroxycitronellal is a synthetic aromatic aldehyde used as a fragrance ingredient in cosmetics and personal care products, valued for its sweet, floral, lily-of-the-valley scent. It serves no skin-treatment purpose and functions purely to add fragrance. |
| Citronellol Fragrance ingredient | Citronellol is a naturally occurring monoterpene alcohol used as a fragrance and flavoring agent, providing a rose-like, citrusy scent in cosmetics and personal care products. It is found in essential oils such as rose, geranium, and citronella. |
| Geraniol Fragrance/aroma compound | Geraniol is a naturally occurring terpene alcohol used in cosmetics primarily as a fragrance ingredient and for its pleasant rose-like scent. It also has mild antioxidant and antimicrobial properties but is included mainly for olfactory rather than therapeutic purposes. |
| Amyl Cinnamal Fragrance ingredient | Amyl Cinnamal (amyl cinnamaldehyde) is a synthetic aromatic compound used as a fragrance and flavoring agent in cosmetics and personal care products to impart a floral, jasmine-like scent. It is one of the 26 fragrance allergens required to be declared on EU cosmetic labels. |
