1, causing skin sensitivity.
White vinegar is strongly acidic. If the dilution is not enough, or the dosage is too large and the frequency of use is too high, it is easy to cause skin sensitivity, redness and tingling. Therefore, when washing your face with white vinegar, you must pay attention to the right amount.
2, red blood.
After washing your face with white vinegar for a period of time, the T area may return to the state of water-oil balance, but it is easy to have red blood on your cheeks. This is because the cuticle thickness of your cheeks and T area is different, so it is suggested to reduce the cleaning strength of your cheeks.
3, aggravate uneven skin color
If you wash your face with white vinegar, you will pay too much attention to cleaning a certain part, which will easily lead to uneven skin color on your face. The key cleaning parts will be whiter than other skin, so pay attention to the overall cleaning and don't ignore the details.
4, causing spots on the skin.
If you wash your face with white vinegar during the day, and you don't do a good job of isolation and sun protection in the later period, it is easy to grow spots on your face after a long time, so white vinegar is easy to react with sunlight. It is recommended to wash your face with white vinegar at night and do follow-up skin care.
5. Destroy the stratum corneum of the skin
Washing your face with white vinegar for a long time, just like brush acid's principle, can change your skin, but it is easy to ruin your face with a little carelessness, so you must control the dosage of white vinegar and avoid washing your face with white vinegar every day.
Second, if it is dry skin, skin metabolism is slow, once a month is enough. If it is oily skin, the frequency of once or twice a week is more appropriate. Because the concentration of personal use is not fixed, the effect is difficult to generalize.
Vinegar contains acetic acid, amino acids, glycerin, sugar and aldehyde compounds, which has a slight irritation to the skin. Wash your face with warm water and add a little white vinegar, which can expand the blood vessels of your skin and make your skin plump. It is recommended that people with sensitive skin or thin stratum corneum should use it with caution.
Extended data:
1, some people will add a few drops of white vinegar or lemon juice when washing their faces, thinking that the fruit acid in lemon is a good natural exfoliating product and can soften the skin. I feel smoother after washing my face. However, this way of washing your face will bring more problems. Exfoliation needs to be determined according to your skin type. If it is dry skin, skin metabolism is slow, once a month is enough. If it is oily skin, the frequency of once or twice a week is more appropriate. Because the concentration of exfoliating ingredients in natural products is not fixed when people use them, it is difficult to generalize the effect.
