Selaginella Lepidophylla Extract
What is Selaginella Lepidophylla Extract?
Selaginella lepidophylla extract comes from a hardy desert fern called the resurrection plant, native to arid environments like the Chihuahuan Desert. This botanical survives prolonged dryness by curling into a dormant state and rapidly rehydrates when water returns, due to its rich polysaccharides including trehalose that stabilize cells and bind water. In skincare formulations, the extract serves as a skin conditioning agent, primarily in the emollient category. It works by coating the skin surface to fill irregularities, promote smoothness, and improve texture feel. This action enhances slip for better application while aiding barrier function alongside occlusives to curb transepidermal water loss. Typically incorporated into creams, lotions, and serums, it draws from the plant's natural hydration resilience to contribute to supple skin appearance without greasiness.
