What it is
A cell culture extract derived from Camellia sinensis (green tea) leaf cells, produced via biotechnology to concentrate antioxidant polyphenols and other bioactive compounds.
How it works
It delivers antioxidants like catechins and flavonoids to the skin, which neutralize free radicals that cause premature aging. It also has anti-inflammatory properties that can reduce redness and soothe sensitive skin.
Pros
Consistent quality
Lab-grown cells ensure a stable, pure extract without seasonal variations or contaminants.
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Cons and cautions
Less studied than whole leaf
Most green tea research uses whole leaf extracts; cell extracts have fewer human studies.
Potentially lower potency
The biotech process may yield lower concentrations of active antioxidants compared to traditional extraction.
Best for
- Anyone looking for antioxidant protection
- People with sensitive or reactive skin
- Those wanting to combat signs of aging from pollution
Use caution if
- Individuals with a known allergy to green tea or Camellia plants
