Literature Review: The Role of Nutritional Adequacy in Preventing Skin Aging

Skin ageing is a natural process experienced by every human being, influenced by environmental, genetic, and lifestyle factors. Premature skin ageing, although natural, can negatively impact a person's self-confidence. This study aims to explore the relationship between nutrient intake—such as vitamin C, vitamin E, vitamin D, omega-3 fatty acids, and other antioxidants—and skin health, focusing on their effects on slowing the skin ageing process. The study employs a qualitative method with a descriptive approach, utilizing a systematic literature review of various academic sources. The findings indicate that nutrients such as vitamin C, vitamin E, vitamin D, omega-3 fatty acids, and antioxidants have the potential to protect the skin from premature ageing. These nutrients contribute to maintaining skin elasticity, preserving moisture, and reducing damage caused by free radicals. This study highlights the importance of optimal nutrient intake in maintaining skin health and delaying the skin ageing process. It provides practical recommendations for incorporating these nutrients into daily diets to promote healthier and younger-looking skin.
