Korzyści Mikrodermabrazji Twarzy z Witaminą C
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.
How much vitamin C you need each day
When it comes to vitamin C, a little bit goes a long way — which is to say, it’s not all that difficult to get your recommended daily amount. For example, one medium orange has about 80 milligrams of vitamin C, which accounts for much of your daily intake.
For adults ages 18 and over, here’s how the National Institutes of Health (NIH) breaks down its vitamin C recommendations:
- Men: 90 mg
- Women: 75 mg
- People who are pregnant: 85 mg
- People who are lactating: 120 mg
“Keep in mind that these recommendations are a minimum to prevent deficiency,” Peart says, “and some experts believe the recommendations should be higher.”
These recommendations also don’t take into account bodily differences like weight, height, sex assigned at birth, overall health, etc. Plus, if you smoke, you’ll need about 35 mg more per day because smoking is toxic to cells, causing your body to use up its vitamin C more quickly.
If you’re not sure how much vitamin C you should be getting, talk to a healthcare provider for personalized guidance.
Signs of a vitamin C deficiency
Most people who live in North America get enough vitamin C in their daily diet. But malnourishment, alcohol use disorder, smoking and eating disorders can all lead to low levels of vitamin C.
“Not getting enough vitamin C is fairly uncommon,” Peart states, “but in some cases, people can become deficient in it.” That can lead to scurvy, a more serious form of deficiency that, though rare in North America, is most commonly seen in people who live in extreme poverty and/or those who are under-housed.
Risks of too much vitamin C
But too much of a good thing is, well, too much. The upper limit of vitamin C supplements is 2,000 mg per day, at doses higher than that, you may experience side effects like:
- Bloating.
- Diarrhea.
- Headaches.
- Flushed skin.
- Cramps and/or an upset stomach.
Function
Vitamin C is needed for the growth and repair of tissues in all parts of your body. It is used to:
Vitamin C is one of many antioxidants. Antioxidants are nutrients that block some of the damage caused by free radicals.
- Free radicals are made when your body breaks down food or when you are exposed to tobacco smoke or radiation.
- The buildup of free radicals over time is largely responsible for the aging process.
- Free radicals may play a role in cancer, heart disease, and conditions like arthritis.
The body is not able to make vitamin C on its own. It does not store vitamin C. It is therefore important to include plenty of vitamin C-containing foods in your daily diet.
For many years, vitamin C has been a popular household remedy for the common cold.
- Research shows that for most people, vitamin C supplements or vitamin C-rich foods do not reduce the risk of getting the common cold.
- However, people who take vitamin C supplements regularly might have slightly shorter colds or somewhat milder symptoms.
- Taking a vitamin C supplement after a cold starts does not appear to be helpful.

Recommendations
Recommendations for vitamin C, as well as other nutrients, are provided in the Dietary Reference Intakes (DRIs) developed by the Food and Nutrition Board at the National Academies of Sciences, Engineering, and Medicine. DRI is a term for a set of reference intakes that are used to plan and assess the nutrient intakes of healthy people. These values, which vary by age and sex, include:
Recommended Dietary Allowance (RDA): The average daily level of intake that is enough to meet the nutrient needs of nearly all (97% to 98%) healthy people. An RDA is an intake level based on scientific research evidence.
Adequate Intake (AI): This level is established when there is not enough scientific research evidence to develop an RDA. It is set at a level that is thought to ensure enough nutrition.
Dietary reference intakes for vitamin C:
- 0 to 6 months: 40 milligrams/day (mg/day)
- 7 to 12 months: 50 mg/day
- 1 to 3 years: 15 mg/day
- 4 to 8 years: 25 mg/day
- 9 to 13 years: 45 mg/day
- Girls 14 to 18 years: 65 mg/day
- Pregnant teens: 80 mg/day
- Breastfeeding teens: 115 mg/day
- Boys 14 to 18 years: 75 mg/day
- Men age 19 and older: 90 mg/day
- Women age 19 year and older: 75 mg/day
- Pregnant women: 85 mg/day
- Breastfeeding women: 120 mg/day
The best way to get the daily requirement of essential vitamins, including vitamin C, is to eat a balanced diet that contains a variety of foods.
Smokers or those who are around secondhand smoke at any age should increase their daily amount of vitamin C by an additional 35 mg per day.
Women who are pregnant or breastfeeding and those who smoke need higher amounts of vitamin C. Ask your health care provider what amount is best for you.
