What it is
A biotech-derived ingredient created by fermenting pumpkin fruit with Lactobacillus bacteria. The fermentation produces enzymes and peptides that gently exfoliate and condition the skin.
How it works
The fermentation process generates natural enzymes (like proteases) that help dissolve the bonds between dead skin cells, encouraging gentle shedding. It also produces peptides and antioxidants that can soothe irritation and support the skin barrier.
Pros
Gentle exfoliation
Provides mild enzymatic exfoliation that is less likely to cause irritation compared to strong acids or physical scrubs.
Soothing properties
The fermentation process can produce compounds that help calm redness and inflammation, making it suitable for sensitive skin.
Cons and cautions
Limited research
Most evidence comes from traditional use and small studies; large-scale clinical trials are lacking.
Variable potency
The activity of the ferment can vary between batches, leading to inconsistent results in different products.
Best for
- People with sensitive or reactive skin seeking gentle exfoliation
- Those with dull or uneven skin texture
- Anyone wanting a natural alternative to chemical exfoliants
Use caution if
- Individuals with known pumpkin or Lactobacillus allergy
- Those with open wounds or active infections on the skin
