Tan, a doctor of dermatology at Fudan University, said in an interview with Science and Technology Daily that the effect of applying fruits and vegetables to the face can't meet people's expectations, because the nutrients contained in fruits and vegetables are not as magical as people think. For example, cucumber does contain vitamin E and vitamin C, but each cucumber 100g contains only 0.98mg of vitamin E and 9mg of vitamin C, both of which are far below the effective concentration and cannot be absorbed by the skin, so its whitening and skin rejuvenation effect is minimal. Moreover, vitamin C is a water-soluble vitamin, which is difficult to be absorbed by the skin. Zhao Juan, director of the Skin Beauty Center of East Tian Li Medical Beauty Clinic, also said that human skin can't absorb high molecular weight substances, while the nutrients in fruits and vegetables have large molecular weight, so most of them can't break through the stratum corneum. In order to achieve the real skin care effect, at least make a fuss about the dermis of the skin.

Self-made fruit and vegetable mask is not only difficult to guarantee the effect, but also may cause facial allergy, infection and inflammation. According to China Daily, the raw materials of homemade fruit and vegetable mask are easily infected by bacteria. In addition, many people don't know enough about the characteristics of fruits. For example, smearing citrus fruits on the face can cause photosensitivity problems of the skin. If you are exposed to the sun after applying your face, it is easy to make your skin black, causing inflammation and redness, which can lead to solar dermatitis. Melons and fruits include cucumbers, tomatoes, red grapes, figs and so on. Therefore, people with sensitive physique can't apply fresh juice to their faces at will. The best way to give full play to the beauty effect of fruits and vegetables is to eat. When eating fruits and vegetables, you can consult their nutrient composition tables to understand the nutritional functions of different fruits and vegetables, which can better improve your skin.

The Beijing Morning Post lists the following fruits and vegetables that may irritate the skin and have negative effects on the skin:

Lemon. Lemon has antibacterial, whitening and other functions, but it contains a photosensitive substance, which can cause phototoxic reaction. If smeared on the face and exposed to ultraviolet rays, it may induce irritating dermatitis, leading to peeling, blistering and even pigmentation.

Tomatoes tomatoes can be used to exfoliate, but too much lycopene will lead to the decomposition of collagen on the face.

Egg white. Egg white can tighten the skin and lift it, but the salmonella contained in it is dangerous to the skin, so try not to apply raw egg white to your face. (Kong Rui)
