Serenoa Serrulata (Saw Palmetto) Fruit Extract is derived from the berries of the saw palmetto plant and contains fatty acids and phytosterols thought to inhibit 5-alpha-reductase, helping reduce sebum production. In topical skincare it is used in formulations targeting oily skin, acne, and hair/scalp products for its potential anti-androgenic and anti-inflammatory effects.
