Ingredient review
Psicose
INCI: PSICOSE
Psicose is a gentle, natural humectant that helps hydrate skin and may offer antioxidant benefits, though research in cosmetics is still limited.
In plain English
Psicose is a type of sugar found naturally in small amounts in foods like figs and raisins. In skincare, it acts like a sponge to attract and hold water in the outer layer of your skin, keeping it hydrated and plump. It also has antioxidant properties, meaning it can help protect your skin from damage caused by things like pollution and UV rays. Because it's a sugar, it's very gentle and unlikely to cause irritation, making it a good option for sensitive skin.

Quick decision guide
Useful, but context matters
Psicose 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 Psicose.
- 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
Psicose, also known as allulose or D-psicose, is a rare sugar (a monosaccharide) that occurs naturally in certain fruits and grains. It is chemically similar to fructose but is not metabolized by the body in the same way. In cosmetics, it is used as a humectant and antioxidant.
How it works
As a humectant, psicose draws moisture from the air into the skin's outer layer, helping to keep it hydrated and reducing water loss. Its antioxidant activity helps neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. This dual action makes it a useful ingredient in moisturizers and anti-aging products.
Pros
Gentle hydration
Psicose attracts moisture to the skin without causing irritation, making it suitable for sensitive skin types.
Antioxidant support
It helps neutralize free radicals, which can reduce oxidative stress and support a more youthful appearance over time.
Cons and cautions
Limited cosmetic research
Most studies on psicose focus on its use as a sweetener, not topical skincare, so evidence for its benefits is still emerging.
Less potent than alternatives
Compared to glycerin or hyaluronic acid, psicose may not provide as dramatic a hydration boost, especially in very dry climates.
Best for
- People with dry or dehydrated skin looking for gentle hydration
- Those with sensitive skin who want a low-irritation humectant
Use caution if
- Individuals with known allergies to rare sugars (very rare)
Usage tips
Safety summary
Psicose is considered safe for topical use in cosmetics. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin. However, long-term studies on its effects in skincare are lacking.
Research notes
Research on psicose in skincare is limited. Most studies focus on its role as a low-calorie sweetener. Preliminary in vitro studies suggest antioxidant and humectant properties, but more clinical trials are needed to confirm its efficacy in cosmetic formulations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Psicose is generally recognized as safe (GRAS) by the U.S. FDA as a food ingredient, but its use in cosmetics is not specifically regulated. It is considered safe for topical application at typical concentrations.
- Common uses
- Moisturizers, Serums, Anti-aging products
- Environmental note
- Psicose is typically produced through enzymatic conversion from plant sugars, which has a lower environmental impact than some synthetic humectants, but large-scale production may still involve energy-intensive processes.
Good to know
- Psicose is also known as allulose and is sometimes listed under that name on ingredient labels.
- It is often derived from plant sources like corn or wheat, so check for allergens if you have sensitivities.
