2. Comparison of the ingredients of three common edible vinegars

|---|---|---|---|
| brewing white vinegar | 4-6% | 2.4-3.4 | amino acids, minerals |
| rice vinegar | 3-5% | 2.8-3.8 | Starch decomposition products |
| Blended with white vinegar | 6-9% | 2.0-2.8 | None |
3. Optimal selection suggestions
1.Preferred brewing white vinegar: Acetic acid concentration is moderate (less than 5% is recommended), contains natural nutrients and is less irritating.
2.Avoid mixing vinegar: High-concentration acetic acid can easily damage the skin barrier. Of the 23 allergic cases exposed on social platforms in the past 10 days, 82% used blended white vinegar.
3.Sensitive skin alternative: Rice vinegar and purified water can be diluted at 1:10. Its mild properties have received 78% praise in Weibo beauty reviews.
4. Correct use method
| Skin type | Recommended ratio | Frequency of use | best time |
|---|---|---|---|
| oily skin | 1:8 (vinegar:water) | 3 times a week | Evening |
| Combination skin | 1:10 | 2 times a week | morning |
| dry skin | 1:15 | 1 time a week | after bathing |
5. Things to note
1.Must be used diluted: Direct use will cause cuticle damage. Xiaohongshu reported 11 burn cases in the past 7 days, all due to undiluted use.
2.Sun protection must be strengthened: Acetic acid will increase photosensitivity, so you need to use SPF50+ sunscreen after use.
3.Performance expectation management: According to a Zhihu dermatologist poll, only 39% of people are suitable for vinegar whitening, and the effective period is about 4-8 weeks.
Summary: Choose brewed white vinegar with less than 5%, scientifically formulated according to skin type, and combined with sun protection measures to safely achieve a mild whitening effect. If redness, swelling and stinging occur, stop using it immediately and seek medical advice.
