What it is
A natural extract derived from a single-celled golden algae, rich in pigments and compounds that protect the algae from environmental stress.
How it works
It donates electrons to neutralize free radicals, reducing oxidative stress on skin cells. It may also calm inflammatory pathways, leading to less redness and irritation.
Pros
Gentle antioxidant
Provides free radical protection without common irritation, making it suitable for sensitive skin.
Soothing potential
Early research suggests it may help calm redness and inflammation, a plus for reactive skin types.
Cons and cautions
Limited evidence
Most benefits are based on lab studies or ingredient supplier data; large human trials are lacking.
Higher cost
Microalgae extracts are often more expensive to produce, which can increase product prices.
Best for
- People with sensitive or reactive skin
- Anyone looking for a gentle antioxidant boost
Use caution if
- Those with known algae allergies (rare)
