The bromelain and vitamin C found in pineapple are both powerful substances that appear to have skin-related health benefits. Bromelain, specifically, has shown some promise in calming the effects of Pityriasis lichenoides chornica (PLC), a skin disease that is defined by scaly raised bumps on the surface of the skin. Bromelain is thought to help relieve symptoms due to its anti-inflammatory, immunomodulatory, and anti-viral properties. Vitamin C, due to its powerful antioxidant properties, has also been strongly linked to skin health. Some of the known benefits of vitamin C include improved collagen synthesis and thickness, less wrinkle depth, and improved wound healing. While using pineapple extracts or applying pineapple directly to the skin may or may not result in healthier skin (more studies are needed), consuming pineapple on a regular basis may provide an overall benefit to your skin's well-being due to its bromelain and vitamin C content.
