With the arrival of summer, many people are out of activities, but suntan is not a minority. All kinds of whitening methods take turns to play by the public pursuit of beauty. Experts from dermatology point out that some hot whitening methods may not be practical, such as lemon water whitening is unreliable, and drinking too much may produce some side effects. The key to whitening should be to do an excellent job of daily sun protection and repair work and daily intake of vegetables and fruit rich in vitamin C.
Lemons are good fruit, sweet and sour, delicious, and attractive taste buds; When it comes to lemons, the words are always “whitening and detoxifying”. Because of this, there are many opinions about lemons on the market. Some people say that drinking lemon water can whiten. Is this method reliable?
Can drinking lemonade whiten your skin?
First, let’s explain the nutrients of lemons. Lemon contains a large number of fruit acids. The most important is citric acid, the proportion of up to 5% so that most lemons will have an acid taste. Lemon water can whiten, mainly from the vitamin C contained in it, because vitamin C has good antioxidants. In addition, it can reduce the precipitation of melanin, so there is a particular whitening effect.
However, some experts point out that simply drinking lemonade to whiten your skin is not practical. The reason is that lemons don’t have much vitamin C, at 22 milligrams per 100 grams. In other words, you might have to eat six lemons a day to get some whitening effect.
Will lemonade turn black during the day?
It will turn black if eaten usually.
Lemon peel contains a coumarin material, which is more sensitive to light. Sunshine during the day is full after it enters the skin internally, absorbs ultraviolet rays, makes its chemical, and may produces melanin, making the skin appear darker. Still, usually, we drink lemon water, often only a few pieces, and to achieve a photosensitive reaction, You need 600 grams of lemon rind, so eating it during the day won’t make your skin dark.
Too many lemons can be rotten for you!
Moderate consumption of lemon water can freshen the taste, regulate appetite, and supplement trace vitamin C; excess will produce side effects. The daily requirement of vitamin C for the human body is 200mg. In clinical practice, some patients have skin yellowing due to excessive drinking of lemon water. Lemon contains an intracarotid. Drinking too much lemon water leads to intracarotid hyper-six, which is usually clinically manifested as yellow skin without obvious allergic symptoms.
In addition to yellowing skin, drinking large amounts of lemon water over a long period may also cause the skin to turn dark. The expert stated that lemon contains photosensitive material, which the human body quickly absorbs through oral use. When our skin exposes to the sunlight, these photosensitive materials and sunlight interact. Not only can it not play a whitening effect, but easy to make the skin darker and even cause the skin to become sensitive.
In addition, drinking too much lemonade has an impact on your teeth. Lemons contain too much acid. If you ignore gargle and clean your mouth in time, acid remains on your teeth, softening them and making them vulnerable to corrosion. Intake of too much acid will cause gastrointestinal discomfort, and severe cases can cause stomach ulcers. Excessive intake of Vitamin C may cause hyperuricosuria and hyperoxaluria. A long-term excessive intake may induce kidney stones or urethral stones.
