Ingredient review
Maltodextrin
INCI: MALTODEXTRIN
Maltodextrin is a gentle, sugar-derived ingredient that helps products feel smooth and slightly hydrating without clogging pores.
In plain English
Maltodextrin is a white powder made from starch (usually corn, potato, or rice). In skincare, it acts like a mild sponge that can hold a little water, helping your skin feel soft and smooth. It also helps other ingredients spread evenly and gives products a silky, non-greasy feel. Think of it as a helper that makes your lotion or serum feel nicer on your skin.

Quick decision guide
Useful, but context matters
Maltodextrin 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 Maltodextrin.
- 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
Maltodextrin is a polysaccharide (a chain of sugar molecules) produced by breaking down starch through partial hydrolysis. It is commonly derived from corn, rice, or potato starch and appears as a fine white powder. In cosmetics, it functions as a binder, absorbent, and mild humectant.
How it works
Maltodextrin works by attracting and holding a small amount of water to the skin's surface, providing light hydration. It also forms a thin, flexible film that helps other ingredients stay on the skin longer and gives a smooth, velvety finish. In powder formulations, it absorbs excess oil and helps create a silky texture.
Pros
Lightweight hydration
Maltodextrin provides a subtle moisture boost without feeling heavy or sticky, making it ideal for daytime use or under makeup.
Improves product feel
It gives serums and moisturizers a smooth, silky texture that glides on easily and absorbs quickly, enhancing the overall user experience.
Cons and cautions
Limited hydration power
Compared to glycerin or hyaluronic acid, maltodextrin holds less water, so it may not be enough for very dry skin on its own.
Potential drying in low humidity
In very dry air, the film formed by maltodextrin can sometimes feel tight or slightly drying if not paired with other moisturizing ingredients.
Best for
- People with normal to combination skin looking for a lightweight hydrator
- Those who prefer gentle, low-irritation ingredients in their routine
Use caution if
- Individuals with very dry or dehydrated skin may need a more potent humectant like glycerin or hyaluronic acid
Usage tips
Safety summary
Maltodextrin is considered very safe for topical use. It has a low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin. No significant safety concerns have been reported in cosmetic concentrations.
Research notes
Research on maltodextrin in skincare is limited but consistent with its role as a mild humectant and texture modifier. Studies on similar polysaccharides support its safety and mild hydrating properties. It is widely used in food and cosmetics with a strong safety record.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. It is generally recognized as safe (GRAS) for topical application.
- Common uses
- Serums, Moisturizers, Masks, Powder formulations
- Environmental note
- Maltodextrin is biodegradable and typically derived from renewable plant sources. However, if sourced from corn, it may involve genetically modified crops unless labeled organic or non-GMO.
Good to know
- Maltodextrin is often used in powder-to-foam cleansers and dry shampoos for its absorbent properties.
- It is considered safe for all skin types and is rarely associated with allergic reactions.
