What it is
A natural extract obtained from the stems of the Cereus hildmannianus cactus, a plant native to South America. It is rich in polysaccharides (complex sugars) and flavonoids, which give it hydrating and antioxidant properties.
How it works
The polysaccharides in the extract form a thin, invisible film on the skin's surface, which helps reduce water loss (transepidermal water loss, or TEWL). The flavonoids act as antioxidants, neutralizing free radicals that can cause premature aging. This dual action helps keep skin plump, smooth, and protected.
Pros
Gentle Hydration
Provides moisture without clogging pores or causing irritation, making it suitable for sensitive and acne-prone skin types.
Antioxidant Support
Contains flavonoids that help neutralize free radicals, potentially reducing signs of aging from environmental stress.
Cons and cautions
Limited Research
There are fewer peer-reviewed studies on this extract compared to classic humectants, so its long-term benefits are less documented.
Variable Potency
The concentration and quality of active compounds can differ between products, leading to inconsistent results for the user.
Best for
- People with dehydrated or dry skin looking for a gentle humectant
- Those with sensitive or reactive skin who want a soothing, low-irritation ingredient
Use caution if
- Individuals with a known allergy to cactus or related plants (rare)
