No, fish skin is rich in nutrition, and the collagen in it will play a cosmetic role, but don't eat too much, because eating too much will make you fat. Collagen is a kind of polymer protein, which can keep skin firm and elastic. It exists in human skin, bones, teeth, tendons and other parts. On the skin side, it forms a reticular support with elastic fibers, providing solid and powerful support for the dermis. With the increase of age, the content of human collagen will gradually lose, and the skin will lose its elasticity, become thinner and aging. Therefore, skin aging is indeed inextricably linked with the loss of collagen.

The nutritional value and nourishing function of fish skin are similar to other skins, but the cholesterol content is the lowest. People who are afraid of eating other hyperlipidemia skins don't have to worry about eating fish skins. There are many ways to eat fish skin, and the most popular is cold fish skin. In addition, braised fish skin, hot and sour fish skin and garlic-flavored grilled fish skin are also good attempts.

When making fish skin, be careful not to blanch it for too long, so as not to affect its crisp taste. People with a bad stomach should not eat more fish skin, which is more difficult to absorb. If you add some vinegar, it can be improved.

While obtaining collagen through food supplement, we should also eat more foods with antioxidant function such as oranges, carrots, tomatoes and grapes to reduce the damage of free radicals to collagen in the body.

At the same time, animal skin contains more fat, so it is best to eat it with vegetables with lipid-lowering effect such as onion, cauliflower, celery and pumpkin.
