Korzyści Mikrodermabrazji Twarzy z Witaminą C
Food Sources
All fruits and vegetables contain some amount of vitamin C.
Fruits with the highest content of vitamin C include:
- Cantaloupe
- Citrus fruits and juices, such as orange and grapefruit
- Kiwi fruit
- Mango
- Papaya
- Pineapple
- Strawberries, raspberries, blueberries, and cranberries
- Watermelon
Vegetables with the highest sources of vitamin C include:
- Broccoli, Brussels sprouts, and cauliflower
- Green and red peppers
- Spinach, cabbage, turnip greens, and other leafy greens
- Sweet and white potatoes
- Tomatoes and tomato juice
- Winter squash
Some cereals and other foods and beverages are fortified with vitamin C. Fortified means a vitamin or mineral has been added to the food. Check the product labels to see how much vitamin C is in the product.
The best food sources of vitamin C are uncooked or raw fruits and vegetables. Cooking vitamin C-rich foods or storing them for a long period of time can reduce the vitamin C content. Microwaving and steaming vitamin C-rich foods may reduce cooking losses. Exposure to light can also reduce vitamin C content. Choose orange juice that is sold in a carton instead of a clear bottle.
Should you take vitamin C supplements?
If you eat a healthy diet, you’re likely already getting enough vitamin C. “You can’t get too much vitamin C from food sources,” Peart says, “so if you eat plenty of vegetables and fruit every day, you will get the recommended amount and more.”
But if you fear you’re not getting enough vitamin C (like if you smoke or if you don’t eat many fruit and veggies), talk to your healthcare provider about whether supplements are safe for you. The usual supplement dosage is 500 mg per day, but they may recommend a different amount.
There are also times when you may want to take extra vitamin C, like if you’re not feeling well.
“If you feel like you’re coming down with a cold or the flu, or if you’re in a period of acute stress and feeling run-down, most people can take up to 1,000 mg vitamin C per day (or temporarily increase your current supplement to that amount),” Peart says. “This helps maintain healthy levels of vitamin C, which get depleted in times of physical stress.”
Indications
Vitamin C deficiency usually arises in the setting of decreased intake or increased requirements or losses. Persons at risk for inadequate intake of the vitamin include patients in the following groups:
Those with alcohol use disorder, anorexia, or cancerThose on restricted diets secondary to inflammatory bowel disease, gastrointestinal reflux, or Whipple disease
Taking medications such as aspirin, indomethacin, oral contraceptives, tetracyclines, and corticosteroids.
Those who have renal failure due to filtration of water-soluble vitamin C during dialysis Those with a complication of interleukin-2 treatment of metastatic renal cell carcinomaIndications
Vitamin C is indicated to prevent and treat scurvy. Scurvy develops 1 to 3 months after initiating a vitamin C deficient diet. Individuals may complain of lethargy, fatigue, malaise, emotional lability, arthralgias, weight loss, anorexia, and diarrhea. They also may experience easy bleeding, bruising, and poor wound healing. The cutaneous manifestations of scurvy include phrynoderma, corkscrew hairs, perifollicular hemorrhage and purpura, edema of the lower extremities, and splinter hemorrhages. Phrynoderma, or enlarged hyperkeratotic hair follicles, initially present on the posterolateral arms. This presentation subsequently generalizes to involve the buttocks, posterior thighs, calves, shins, and back. Corkscrew hairs represent fractured and coiled hairs due to impaired keratin cross-links by disulfide bonds. With time, significant vascular congestion occurs, particularly in the lower extremities, leading to perifollicular hemorrhage and edema. This purpura is occasionally palpable, mimicking a cutaneous vasculitis. Blood vessel wall fragility also results in splinter hemorrhages of the nail bed. Oral disease is prominent among those with pre-existing poor dentition. Individuals may develop hemorrhagic gingivitis, where the gingiva is initially red, swollen, and shiny and later becomes purple, necrotic, and prone to bleeding. Additionally, poorly formed soft teeth are prone to infection. Musculoskeletal disease frequently presents in children. Hemorrhage can be intramuscular, intra-articular, or subperiosteal, leading to pain and pseudoparalysis. Bowing of the long bones, depression of the sternum, and swelling of the costochondral junctions are present on physical examination. Radiographic findings include a transverse metaphyseal radiolucent band (scurvy line or Trummerfeld zone), widening at the zone of calcification (white line of Frankel), a ring of increased density around the epiphysis (Wimberger ring), and metaphyseal spurs with marginal fractures (Pelkan spurs). Reports exist of conjunctival, intraocular, intracerebral, and gastrointestinal bleeding.
More ways to get your fill of vitamin C
You don’t have to chow down on a stalk of kale or chug a glass of orange juice to get your vitamin C fix. Peart shares more easy tips for getting your daily dose of this vitamin in tasty, easy-to-prepare ways:
- Get strategic about breakfast. Sautéed spinach and other veggies are perfect additions to omelets. And Peart loves turning frozen wild blueberries into a simple topping for yogurt or protein pancakes. “Just heat them in a pot on the stove over low heat until they’re saucy,” she says.
- Be a smart snacker. Keep fresh fruit and veggies on hand for snacking, along with yogurt, hummus or salsa to dip them in. Peart also recommends freezing grapes for a refreshing summer snack. They don’t have quite as much vitamin C as other fruits, but they’re packed with so many nutrients that they’re always a healthy choice.
- Blend it up. Make smoothies with fresh or frozen fruit and half a cup of frozen greens (for example, spinach and kale). You’ll get two servings of fruit and one serving of vegetables — and you won’t even taste the veggies! (“If veggies are your jam, though, try a green smoothie made mainly of veggies blended with yogurt, milk, or water,” Peart suggests.)
- Choose vitamin C-rich sides. “Enjoy pinwheel slices of oranges or grapefruit as a side to grilled chicken for dinner with a Mediterranean vibe,” Peart says, “or make a mango chutney as a dinner side for a tropical twist.” You can also add berries or citrus fruits to summer salads and pomegranates, pears or persimmons to winter salads.
- Freeze fruit for later. Puree veggies and fruit and store in ice cube trays in the freezer, for use in muffins. Keep frozen berries on hand to add to muffins and cereals, and freeze one-inch segments of peeled banana to drop into smoothies.
“Orange” you glad you know all of these ways to load up on vitamin C? Your body will thank you for it — and your taste buds aren’t likely to complain either.
Jakie są korzyści z mikrodermabrazji?
Mikrodermabrazja jest korzystna dla osób o każdym odcieniu i typie skóry, od normalnej po mieszaną i ze skłonnością do trądziku. Zabieg jest najskuteczniejszy w przypadku łagodnego trądziku i zaskórników. Prawdopodobnie nie pomoże jednak w przypadku trądziku torbielowatego i może pogorszyć stan zapalny. Z czasem może również pomóc zlikwidować drobne uszkodzenia słoneczne.
Jeśli regularnie poddajesz się mikrodermabrazji, możesz spodziewać się zarówno krótkotrwałych, jak i długoterminowych efektów zabiegu.
– Mikrodermabrazja natychmiastowo poprawia strukturę skóry, wygładzając jej górną warstwę – mówi dr Palm. Dodaje, że zabieg ma również pozytywny wpływ na krążenie, dzięki czemu skóra może być rozjaśniona przez kilka godzin, a nawet kilka dni po zabiegu.
– Regularne zabiegi mikrodermabrazji mogą z czasem spowodować nawet minimalny wzrost poziomu kolagenu – mówi dr Palm. Takie zwiększenie objętości kolagenu w skórze może pomóc zminimalizować pojawianie się drobnych linii, zmarszczek i innych oznak starzenia.
Niektóre osoby dobrze reagują nawet na cotygodniową mikrodermabrazję, ale osoby o bardziej wrażliwej skórze lepiej zareagują na zabiegi z częstotliwością comiesięczną lub dwumiesięczną. Specjalista-dermatolog może pomóc określić, jaka częstotliwość będzie dla ciebie odpowiednia.
