Urea is a naturally occurring component of the skin's natural moisturizing factor that hydrates by attracting and retaining water; at higher concentrations it also softens and exfoliates thickened or scaly skin. It is widely used to treat dry skin conditions such as xerosis, ichthyosis, and hyperkeratosis.
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.
Linoleic acid is an essential omega-6 polyunsaturated fatty acid and a key component of skin ceramides that helps maintain the epidermal barrier and reduce transepidermal water loss. It is also studied for normalizing sebum composition and reducing comedone formation in acne-prone skin.
Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity.
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 contact irritation | Rare | Occasional redness or stinging, usually in sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Isolated case reports; considered a low-sensitizing ingredient. |
| Comedogenicity / clogged pores | Rare | Generally low comedogenic potential, but acne-prone individuals may occasionally react. |
| Skin irritation or redness | Rare | Mild localized irritation can occur in sensitive individuals. |
| Comedogenicity (pore clogging) | Rare | Generally considered low risk, but may contribute to clogged pores in some acne-prone users. |
| Mild skin irritation | Uncommon | Transient stinging or redness, more likely on compromised or sensitive skin. |
| Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |
| Skin irritation | Uncommon | Mild redness or itching, generally low irritancy potential. |
| 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. |
