What it is
An extract derived from Cladonia rangiferina, a fruticose lichen commonly known as reindeer moss. It contains bioactive compounds like usnic acid and polysaccharides that contribute to its soothing and antioxidant effects.
How it works
The extract's antioxidant compounds help neutralize free radicals, which are unstable molecules that can damage skin cells. Its polysaccharides may form a protective film on the skin, reducing moisture loss and calming irritation.
Pros

Reindeer moss extract is generally well-tolerated and unlikely to cause irritation, making it suitable for sensitive skin types.
Natural antioxidant
It helps protect skin from environmental stressors like pollution, which can contribute to premature aging.
Cons and cautions
Limited research
Most studies are lab-based or on animals; more human trials are needed to confirm its benefits for skin.
