What it is
Potato Pulp Water is the water-soluble fraction obtained from the pulp of potatoes (Solanum tuberosum). It is a byproduct of potato processing and is used in cosmetics for its hydrating and soothing properties.
How it works
When applied to the skin, Potato Pulp Water provides a light layer of hydration. The natural sugars and minerals in the water may help attract and hold moisture to the skin's surface, while the water itself can temporarily soothe irritation by cooling and refreshing the skin.
Pros
Lightweight hydration
Potato Pulp Water adds a thin layer of moisture without feeling heavy or sticky, making it ideal for oily or combination skin types.
Soothing potential
The water content can provide a cooling, calming effect on the skin, which may help reduce temporary redness or irritation.
Cons and cautions
Limited research
There are very few studies on Potato Pulp Water's specific benefits for skin, so its effectiveness is not well-established compared to other humectants.
Potential allergen
People with potato or nightshade allergies may experience a reaction, so patch testing is recommended.
Best for
- People with oily or combination skin looking for a light hydrating mist
