Collagen is a crucial protein found in bones, muscles, skin, and tendons that provides strength and elasticity to tissues. It is obtained from sources such as marine organisms, cows, pigs, and chickens and is widely used in medicine and cosmetics. Hydrolyzed collagen peptides in the form of powder or liquid are typically used in food supplements. Marine collagen, produced from fish skin, is considered a high-quality source of collagen in food supplements. Research suggests that supplementation of hydrolyzed collagen improves skin hydration, elasticity, and collagen content. UV radiation, aging, and environmental toxins lead to the breakdown of collagen, causing wrinkles, dryness, and reduced elasticity. Excessive sun exposure should be avoided to boost collagen production. However, collagen supplementation has potential risks, including allergies and product quality. Oral supplements based on hydrolyzed collagen show promising results for the health and well-being of the skin, especially when sourced from marine collagen.
