3. Kiwi

Kiwifruit is known as the king of vitamin C, which shows how much vitamin C it contains.

4. Carrots

Carrots are rich in vitamin C, which can inhibit melanin synthesis, prevent fat oxidation, and prevent lipofuscin deposition. Therefore, regular consumption of carrots can make **white and delicate.

5. Oranges

Oranges are very nutritious, and one orange can almost meet the amount of vitamin C that the human body needs every day. Tangerines contain more than 170 plant compounds and more than 60 flavonoids, most of which are natural antioxidants.

6. Grapefruit

Grapefruit contains a lot of vitamin C, which can reduce blood cholesterol, but grapefruit should not be eaten too much.

Recent studies in the United States have found that vitamin C can act as a catalyst to help produce a "genotoxin", and this toxin will cause DNA mutations (carcinogenesis, etc.) when it interacts with DNA, the genetic material deoxyribonucleic acid. Vitamin C can repel harmful free radicals in cells, which are highly active molecules, in addition to directly damaging DNA, they can also work indirectly by converting linoleic acid. Linoleic acid is the main polyunsaturated fatty acid found in sunflower seeds, grapes, safflower, edible oils and human plasma.

Free radicals first convert linoleic acid into another substance called lipid hydroperoxide, and then when a metal ion is present and acts as a catalyst, the lipid hydroperoxide is further degraded into a "genotoxin" that destroys DNA. In test-tube experiments, it was also found that vitamin C was able to substitute its effect in the absence of metal ions, while inducing the production of "genotoxins" from lipid hydroperoxides. Therefore, vitamin C not only protects DNA, but also has the ability to harm DNA.

Do not take it for a long time, otherwise there is a risk of symptoms of scurvy when you stop using it suddenly!

1. Vitamin C can effectively whiten and remove freckle. Vitamin C can inhibit the formation of melanin, can lighten or even remove the pigmentation on the **, and can also help resist the damage of ultraviolet rays to the skin and keep the skin fair.

2. Vitamin C can help the skin to resist oxidation, effectively fight free radicals that cause skin oxidation, delay aging, and prevent the premature appearance of wrinkles and pigmentation.

3Vitamin C can help strengthen the skin. Vitamin C can promote metabolism, improve immunity, strengthen skin cells and increase elasticity, and can also strengthen the resistance to ultraviolet damage from the sun.

4Vitamin C can help maintain the elasticity of the skin, mainly because vitamin C can help promote the synthesis of collagen in the skin, which can support the skin, maintain skin elasticity and reduce the appearance of wrinkles.

If collagen synthesis is blocked, in addition to wrinkles and injuries, blood vessels will also rupture and bleed due to the reduction of support from peripheral tissues, resulting in purple spots. This is a problem that arises due to the gradual decrease in vitamin C levels within aging**. \x0d\x0a2.

Antioxidant effect, protect ** from ultraviolet damage X0D X0A** will be subject to ultraviolet rays, smoking and other chemical and physical damage, the formation of free radicals, these free radicals will cause cell damage, collagen degeneration and aging wrinkle changes, and even cause cell immunosuppression, abnormal differentiation, and the formation of **cancer. Vitamin C is a powerful antioxidant that captures, neutralizes, and protects against UV damage. Therefore, vitamin C can also be called "intradermal sunscreen", although it cannot absorb or block ultraviolet rays, it can have the effect of protecting against ultraviolet damage in the dermis.

Vitamin C is a natural antioxidant that has great benefits on the skin and is an essential ingredient for beauty and skin care. What are the benefits of vitamin C for the skin? Let's take a look at what vitamin C does for the skin!

When vitamin C acts on the dermis, it can also play a role in resisting ultraviolet damage in the dermis and can avoid darkening.

2. Antioxidant.

Vitamin C is a very good antioxidant that can help eliminate free radicals that cause oxidation, slow down the rate of skin aging, and prevent the appearance of wrinkles and dark spots.

3. Strengthen the skin.

Vitamin C can also boost metabolism, improve immunity, strengthen skin cells and increase elasticity. At the same time, it also strengthens the skin's damage to the sun's ultraviolet rays, and when it acts on the skin, it can make the skin have a healthier and stronger skin.

4. Promote collagen synthesis.

The dermis of our skin is full of collagen, and collagen is also an important part of supporting the skin, but with the increase of age and external factors, it will affect the loss of collagen in the skin.
