Disease analysis: vinegar is not only a good condiment, but also has a good cosmetic effect. This is because the main component of vinegar is acetic acid, which has a strong bactericidal effect and can protect skin and hair. Cleaning the skin with vinegar water can make the skin absorb some urgently needed nutrients, thus softening the skin and enhancing its vitality. Adding a tablespoon of vinegar to the washing water and washing it repeatedly with clear water also has a cosmetic effect. If you want to make fingernails and toenails shiny, you can add half a teaspoon of vinegar to warm water, soak it in it, and then trim it. At this time, not only the nail skin is easy to trim, but also the dirt in the nail seam is easy to remove. Suggestion: When many people take a bath, put some vinegar in the water, which will relax muscles, eliminate fatigue and make the skin smooth. It should be white vinegar. You can't wash your face until the vinegar is diluted. If you wash your face directly with vinegar, it will irritate your skin. After washing your face, add a few drops of white vinegar to a basin of clear water and rinse it repeatedly, then pat it dry, which has a good whitening effect.
