Ingredient review
Ethyl Carbazido Hyaluronate
INCI: Ethyl Carbazido Hyaluronate
A next-gen hyaluronic acid derivative that binds to skin for longer-lasting hydration, but research is still emerging.
In plain English
Ethyl Carbazido Hyaluronate is a modified version of hyaluronic acid, a substance your skin naturally makes to stay plump and hydrated. The 'ethyl carbazido' part is a chemical tweak that helps it stick to your skin longer, so the moisture stays put instead of evaporating. Think of it as hyaluronic acid with better grip.

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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic derivative of hyaluronic acid, modified with an ethyl carbazido group to improve its binding affinity to skin proteins, enhancing its water-holding capacity and longevity on the skin.
How it works
It works by forming a thin, flexible film on the skin's surface that attracts and holds water molecules. The ethyl carbazido group allows it to bind more tightly to the skin's natural proteins, reducing wash-off and prolonging hydration effects compared to standard hyaluronic acid.
Pros
Enhanced skin binding
The ethyl carbazido modification helps the ingredient adhere to skin proteins longer, meaning hydration lasts through washing and daily activities.
Gentle on skin
With low irritation and comedogenic risk, it's suitable for most skin types, including sensitive and acne-prone skin.
Cons and cautions
Limited research
As a newer ingredient, there are fewer peer-reviewed studies on its long-term efficacy and safety compared to traditional hyaluronic acid.
Higher cost
The modification process makes it more expensive to produce, which can increase the price of products containing it.
Best for
- People with dry or dehydrated skin looking for advanced hydration
- Those who want a plumping effect without invasive treatments
- Sensitive skin types seeking a gentle humectant
Use caution if
- Individuals with known allergies to hyaluronic acid derivatives (rare)
