Ingredient review
Hydroxyethoxyethyl Urea
INCI: Hydroxyethoxyethyl Urea
A modern humectant that hydrates without stickiness, ideal for lightweight formulas and sensitive skin.
In plain English
Hydroxyethoxyethyl urea is a lab-made ingredient that acts like a moisture magnet. It pulls water into the outer layer of your skin and helps keep it there, but unlike glycerin or hyaluronic acid, it leaves a silky, non-tacky finish. Think of it as a hydrator that disappears into your skin without any sticky residue.

Quick decision guide
Easy yes for most routines
Hydroxyethoxyethyl Urea is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydroxyethoxyethyl Urea.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic urea derivative designed as a humectant. It is a clear, viscous liquid that is highly water-soluble and stable in formulations.
How it works
It binds water molecules from the environment and deeper skin layers, increasing the water content in the stratum corneum (the skin's outermost barrier). Its smaller molecular size allows it to penetrate slightly deeper than some traditional humectants, providing sustained hydration.
Pros
Non-sticky hydration
Unlike glycerin or hyaluronic acid, this ingredient leaves a silky, almost powdery finish, making it ideal for daytime use under makeup or sunscreen.
Gentle on sensitive skin
It has a very low irritation potential and is often well-tolerated even by those with reactive or compromised skin barriers.
Cons and cautions
Less proven than classics
Compared to glycerin or hyaluronic acid, there are fewer long-term studies on its efficacy and skin benefits, so it's best used as a supporting humectant.
Needs companions in dry climates
In very low humidity, humectants can draw moisture from deeper skin layers. Pairing with an occlusive like squalane or shea butter is recommended.
Best for
- Anyone seeking lightweight, non-sticky hydration
- People with oily or acne-prone skin who avoid heavy creams
Use caution if
- Those with severely dehydrated skin may need a more potent humectant paired with occlusives
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. It has a low irritation and comedogenic rating, making it suitable for most skin types. No significant safety concerns have been raised in cosmetic use.
Research notes
Moderate evidence supports its humectant properties and skin feel benefits. Most data come from formulation studies and cosmetic ingredient reviews rather than large-scale clinical trials. It is generally regarded as safe and effective for its intended use.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of cosmetic ingredients generally).
- Common uses
- Serums, Moisturizers, Eye creams, Sheet masks
- Environmental note
- Synthetic origin; no specific environmental concerns reported, but as a synthetic compound, its biodegradability is not as well-documented as some natural humectants.
Good to know
- It is often used as a glycerin alternative in 'non-sticky' formulas.
- It can enhance the feel of other humectants, reducing tackiness.
