The potential of the marine-based nutricosmetic

The marine environment’ biodiversity is a treasure chest of bioactive molecules helpful to developing nutricosmetic products. Sponges, microalgae, macroalgae, tunicates, mollusks, bryozoans, and bacteria produce peptides, polysaccharides, terpenoids, fatty acids, pigments, polyphenols, and minerals that have antibacterial, antioxidant, and anti-inflammatory properties. Marine-derived biomolecules respond to the request of the market for natural and sustainable nutricosmetics. It is possible to obtain bioactive molecules to develop sustainable cosmetic products with lightening, rejuvenating, anti-aging, and hydrating effects on the skin by recycling marine waste. For example, microalgae are rich in antioxidants such as β-carotene and vitamins C and E. Macroalgae are an essential source of polyphenols, amino acids, terpenoids, and lipids, which can decrease blemishes, redness, firming skin, and sun damage, and increase hydration, and remineralizing. Marine collagen is structurally similar to human Type I collagen, has higher bioavailability, and is easily absorbed by the body. The present work discusses challenges and opportunities to advance sustainable blue cosmetics.
