About Vitamin C, a nutrient everyone is familiar with, people have different views. Can Vitamin C really whiten the skin? Do all VC products have a whitening effect? Is VC a beauty drug or poison? The editor has summarized 8 major VC whitening myths, come and take a look!
Can Vitamin C really whiten the skin?
Everyone knows it can prevent scurvy and boost immunity. However, many people may not be familiar with the VC whitening effect, which is highly recommended by numerous beauty experts. In fact, Vitamin C has long been widely used in whitening skincare products, earning the reputation of a "classic natural whitening ingredient." Oral intake of Vitamin C starts from the melanocytes in the skin's basal layer, inhibiting tyrosinase activity, blocking melanin production, and improving skin's translucency from the inside out.
What is a safe daily dosage of VC?
If you are approaching it from the perspective of long-term skincare maintenance, it is recommended to take around 100 milligrams daily, which is both safe and effective and will not cause so-called side effects. Additionally, it is advisable to choose natural Vitamin C products. Here's a tip for everyone: only truly all-natural VC products can be named "Natural Vitamin C." There are many VC products on the market, some costing just a few or ten-plus yuan, but these are generally synthetic VC products, so be careful when choosing!
Is natural Vitamin C really better than synthetic Vitamin C?
Although there is no difference in the chemical composition between the two, natural VC is generally made from rare fruits such as acerola cherry and kiwi. It contains trace elements like Vitamin P that prevent VC from being oxidized and destroyed, helping the body absorb VC better. Synthetic VC has a low cost and generally comes in higher doses. If you consume more than 1000 milligrams of VC per day, it can easily lead to oxalic acid or uric acid stones. For example, some over-the-counter (OTC) medicinal VC products fall under the category of medicine and are generally used as an adjunct to treat diseases. Long-term use is not recommended.
How many times a day is it best to take VC?
It's best to take it twice a day. Because VC is a water-soluble vitamin, it is generally excreted through body fluids within 3-4 hours. Replenishing it every 3-4 hours can ensure the body's VC content, and the absorption effect will be better.
When is the best time to take VC?
The best time is after breakfast or lunch! Everyone knows the saying, "Fruits are gold in the morning and silver at noon." The same goes for VC. Especially for VC products extracted from natural fruits, it's best to take them with breakfast or lunch for the best effect.
If you want to whiten your skin by taking VC orally, how long will it take?
Whitening is like a war; the battle with melanin requires a continuous supply of "bullets," otherwise, the melanin that has just been repelled will quickly rally and its "combat effectiveness" will be even stronger. It will take at least 3-6 months of oral intake for the effect to become relatively obvious. This is because after being absorbed by the digestive system, it takes a process for the body to help cells renew gradually to improve skin tone from the root. Any exaggerated claims about its effects are not beneficial to your health.
Can I just eat more fresh fruits and vegetables rich in VC to whiten my skin?
It depends on individual constitution. Cherries, kiwis, cucumbers, strawberries, tomatoes, oranges, etc., are rich in Vitamin C. However, although Vitamin C is widely found in vegetables and fruits, it is one of the most unstable water-soluble antioxidants with a short shelf life and is highly susceptible to oxidation. For example, green leafy vegetables lose 5-18% of their VC content within 2 hours of being picked, and 38-66% after 10 hours. Moreover, most vegetables consumed by Chinese residents are cooked, and VC is lost severely during cooking, with a utilization rate of less than 50%. Therefore, the amount of VC obtained from vegetables and fruits often fails to reach the functional dosage required for an ideal beauty effect. If you want to whiten your skin, it is recommended to increase your VC intake.
Are the homemade VC whitening masks popular online really effective?
The popular online method of crushing Vitamin C, dissolving it in mineral water, and then using it with a compressed mask is effective in the short term. However, because VC has strong antioxidant properties, if not handled properly, it can easily cause a stinging sensation. Girls with sensitive skin should not try this.
