What it is
Oyster extract is a natural ingredient derived from the common oyster (Ostrea edulis). It is typically processed to concentrate its mineral and amino acid content, then added to skincare products as a conditioning and soothing agent.
How it works
In skincare, oyster extract provides minerals (like zinc and copper) that are essential for skin health. Zinc can help calm inflammation and support healing, while copper is involved in collagen production. The amino acids in the extract also act as humectants, drawing moisture into the skin and helping it feel softer and more supple.
