To maintain the skin, in addition to rubbing skin care products every day, many people will also use "eating" to assist, hoping to keep their skin satisfied. Dermatologist Karen Burke mentions that many skincare products may contain vitamins that are known as antioxidants, but the problem is that rubbing them on the skin may have limited or short-term effects. Another dermatologist, Azad Sherazi, said in an interview with Business Insider that she supplements health food every day, which is not only good for the skin, but also has anti-aging properties, but what to eat to help the skin?
强化骨骼、紧致肌肤:维生素 D、E
Vitamin D
The main natural source of vitamin D is sun exposure, and a lack of vitamin D can lead to feelings of tiredness, low mood, or osteoporosis. However, long-term exposure to the sun can also cause sunburn and dry epidermis.
Xue Lazi mentioned that after a blood test, she found that her vitamin D level was low because of frequent sun protection, so she began to supplement vitamin D through health foods to reduce the need for sunlight, so as to reduce the possible damage caused by sunlight to the skin.
On top of that, as people age, their skin becomes less efficient at making vitamin D, and the kidneys are less able to convert vitamin D into its active form, so vitamin D supplementation has more benefits for people over the age of 70.
Vitamin E
Xue Lazi mentioned that people's bones support our skin like scaffolds, so the higher the bone density, the less likely the appearance is to wrinkle or sag. In addition to vitamin D, she also supplements with vitamin E to strengthen bones, which has been proven to prevent bone loss due to the decline in estrogen in women in their 40s~50s after menopause, a congenital factor that makes additional vitamin E supplementation even more important.
Burke mentioned that some studies have suggested that rubbing vitamin E on the skin can reduce sun irritation and improve skin texture.
Promotes the formation of collagen: vitamin C
Vitamin C, the most common antioxidant found in vegetables and citrus fruits, is widely recognized as an important nutrient in the prevention of accelerated aging, as well as collagen production in the skin, increasing skin firmness, and helping to lighten or reduce dark spots.
If you want to get rid of vitamins that can resist aging and indirectly make your skin healthier, you can also refer to eating multivitamin products. Vitamin A, for example, has the functions of improving skin, reducing fine lines, reducing collagen breakdown, even skin tone, and regulating facial oil.
Reduces skin moisture loss: Vitamin B3
Nicotinamide is a chemical form of nicotinic acid (vitamin B3) that can cause fatigue and dry skin if vitamin B3 is deficient. It's like a glue that binds skin cells together, strengthening the skin's natural barrier, and Xue says it's a popular ingredient in the skincare world. It also helps replenish the body's DNA-repair enzymes, which help reduce the damage caused by the sun's rays to the epidermis.
Supplementing with niacinamide or vitamin B3 can reduce moisture loss, reduce the appearance of pores, and reduce fine lines and pigmentation, making it an indispensable supplement for skin care.
Brightens skin tone: Resveratrol
Resveratrol is a plant compound found in foods such as grapes, blueberries, peanuts, and it may help prevent cardiovascular disease, neurological disease, and more.
It has the same antioxidant properties as niacinamide, and also helps to brighten the skin tone and increase skin elasticity, according to Xue Lazi. In addition, resveratrol also has a calming effect on the skin, which can reduce the symptoms of skin inflammation and redness, and can also improve dry or rough skin. When consuming health products, it is important to pay attention to whether the dosage is beyond the recommended daily consumption range, as excessive amounts may lead to unnecessary health risks, such as excessive calcium and vitamin D, which may increase the risk of kidney stones, and long-term intake of too much vitamin E may also lead to hemorrhagic stroke or diarrhea.
