Iron pays attention to hidden keys that help the skin produce collagen
Oct 22, 2025
One of the most important factors supporting skin health is 'collagen', a type of protein.
Collagen plays a key role in maintaining skin elasticity and moisture, but it naturally decreases with age. For this reason, many people visit collagen supplements or skincare products. In fact, certain nutrients must work together in order for collagen in the body to be stably synthesized.
In fact, it has long been known that iron affects collagen protein expression. However, iron has been mainly illuminated only in terms of anemia prevention and blood health, and its association with skin health has not received much attention. In recent years, as the importance of fundamental care in the skin and beauty fields has grown, this old fact is attracting attention again.
According to a paper published in the Journal of the Korean Society of Food and Nutrition Science "Comparison of the Effects of Treatment of Vitamin C, Silicon, Iron, Proline, and Lysine on the Proliferation of Skin Fibroblasts and the Expression of Collagen Ⅰ and Ⅲ" Iron is not just a nutrient involved in oxygen transport. Iron is essential for the enzymes necessary for collagen protein expression and cell expression to work properly. Lack of iron can lead to a lack of stable collagen structure in the skin, which can lead to poor elasticity or delayed wound recovery.
Experts stress that it is the balance of nutrition in daily life that is important to contribute to boosting health and the skin's fundamental regenerative capacity.
