Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products.
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.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Allergic contact dermatitis | Rare | Documented in patch-test studies but considered a relatively weak sensitizer. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| 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. |
| Mild transient skin irritation or stinging | Uncommon | More likely at higher concentrations or on compromised skin barriers. |
| Contact dermatitis / allergic sensitization | Rare | Occasional case reports; patch testing can confirm. |
| Eye irritation on accidental contact | Uncommon | Relevant mainly in leave-on or rinse-off products near the eye area. |
| Mild transient irritation or stinging | Rare | Generally well tolerated; occasional mild reactions, often on compromised or sensitive skin. |
| Mild irritation or stinging | Rare | Transient irritation may occur, more often on compromised or sensitive skin. |
| Contact urticaria | Very rare | Isolated reports of immediate hives following topical exposure. |
| Redness or dryness in low-humidity environments | Uncommon | Can draw moisture from skin if ambient humidity is very low and not sealed with an occlusive. |
| Hypersensitivity reactions with injectable forms | Very rare | Relevant mainly to dermal filler use, not topical cosmetic application. |

| Ingredient | What it does |
|---|---|
| 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. |
| 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. |
| 2-Hexanediol Humectant/preservative-booster | 1,2-Hexanediol (commonly written 2-hexanediol) is a multifunctional diol used in skincare primarily as a humectant, solvent, and preservative-enhancing agent that improves the antimicrobial efficacy of formulations. It is generally well tolerated and considered a base/formulation ingredient rather than a treatment active. |
| Allantoin Key active Soothing/skin-conditioning agent | Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products. |
| 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. |
| Sodium Hyaluronate Humectant / hydrator | Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan that attracts and binds water to the skin to improve hydration and surface plumpness. Its lower molecular weight allows better penetration than native hyaluronic acid. |
| Pentylene Glycol Humectant / solvent / preservative-booster | Pentylene glycol is a glycol used in cosmetics as a humectant and solvent that also enhances the antimicrobial efficacy of formulations, helping reduce reliance on traditional preservatives. It improves skin hydration and aids the delivery and stability of other ingredients. |
| Sodium Hyaluronate Crosspolymer Humectant / hydrating agent | Sodium Hyaluronate Crosspolymer is a chemically cross-linked form of sodium hyaluronate that forms a hydrated network, providing enhanced moisture retention and longer-lasting surface hydration compared to standard hyaluronic acid. It is widely used in moisturizers, serums, and masks to plump and smooth the skin surface. |
| Hydrolyzed Hyaluronic Acid Humectant / moisturizer | Hydrolyzed hyaluronic acid is a low-molecular-weight form of hyaluronic acid broken into smaller fragments, allowing better penetration into the skin to bind water and improve hydration. It is widely used in moisturizers and serums to enhance skin moisture content and surface smoothness. |
| 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. |
| 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. |
| Hydrolyzed Sodium Hyaluronate Humectant / hydrating agent | Hydrolyzed sodium hyaluronate is an enzymatically or chemically fragmented, low-molecular-weight form of sodium hyaluronate used in skincare to attract and bind water. Its smaller size allows better penetration into the upper layers of the skin compared to high-molecular-weight hyaluronic acid, supporting surface hydration and a smoother appearance. |
