Desert Algae Extract
INCI: Scenedesmus deserticola extract
A gentle, hydrating algae extract that helps skin retain moisture and defends against environmental stress, though research is still emerging.
In plain English
This is an extract from a type of algae that lives in very dry, desert conditions. In skincare, it acts like a sponge to help your skin hold onto water, keeping it plump and hydrated. It also contains natural antioxidants that can help protect your skin from damage caused by pollution and UV exposure, though it is not a sunscreen.

What it is
A natural extract derived from Scenedesmus deserticola, a microalgae species adapted to survive extreme dryness and high UV radiation in desert environments.
How it works
It forms a protective film on the skin's surface that reduces water loss (transepidermal water loss, or TEWL), while its antioxidant compounds help neutralize free radicals that can cause premature aging.
Pros
Excellent hydration
Helps skin attract and retain moisture, making it feel softer and more supple throughout the day.
Gentle and soothing
Unlikely to cause irritation, making it suitable for sensitive or reactive skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are still needed to confirm long-term benefits.
Potentially less potent
Compared to classic humectants like glycerin or hyaluronic acid, its hydrating effect may be milder.
Best for
