Ingredient review
Chitosan Lauramide Succinamide
INCI: Chitosan Lauramide Succinamide
A gentle film-forming ingredient derived from chitosan that helps lock in moisture and improve product feel on skin.
In plain English
Chitosan Lauramide Succinamide is a modified version of chitosan, which comes from the shells of shrimp and other crustaceans. In skincare, it forms a thin, flexible film on your skin that helps hold moisture in and makes products feel smooth and silky. Think of it like a lightweight, breathable shield that keeps your skin hydrated without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
Chitosan Lauramide Succinamide 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 Chitosan Lauramide Succinamide.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic polymer created by chemically modifying chitosan (a natural polysaccharide from crustacean shells) with lauramide and succinamide groups. This modification makes it more water-soluble and easier to use in cosmetic formulas.
How it works
When applied to the skin, it dries down to form a clear, flexible film that physically reduces water loss from the skin's surface. This film also helps other ingredients stay in place longer and gives a smooth, velvety feel to the skin.
Pros
Gentle moisture barrier
Forms a lightweight film that helps keep hydration locked in without clogging pores or feeling heavy, making it suitable for most skin types.
Improves product texture
Gives a smooth, velvety feel to creams and serums, enhancing the overall user experience and making application more pleasant.
Cons and cautions
Shellfish origin may concern some
Because it's derived from crustacean shells, people with severe shellfish allergies may want to patch test or choose alternatives, though the allergenic protein is usually removed.
Limited independent research
Most studies focus on chitosan itself; data on this specific modified version is still emerging, so long-term benefits are less established.
Best for
- People with dry or dehydrated skin looking for extra moisture retention
- Anyone who enjoys a smooth, silky finish from their skincare products
Use caution if
- Individuals with a known severe shellfish allergy who prefer to avoid any crustacean-derived ingredients
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. The modification process reduces potential irritation compared to unmodified chitosan. Patch testing is recommended for those with shellfish allergies.
Research notes
Research on chitosan derivatives supports their film-forming and moisturizing properties, but specific studies on Chitosan Lauramide Succinamide are limited. Most evidence is extrapolated from broader chitosan research.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup primers
- Environmental note
- Chitosan is sourced from shellfish waste, making it a byproduct of the seafood industry, which can be considered more sustainable than some synthetic polymers.
Good to know
- This ingredient is often used in 'biodegradable' or 'eco-friendly' formulas because chitosan itself is derived from renewable sources.
- It is not the same as unmodified chitosan, which is less water-soluble and can feel tacky on skin.
