| Influencing factors | Specific performance |
|---|---|
| UV irradiation | Stimulate tyrosinase activity and accelerate melanin synthesis |
| Hormone changes | Pregnancy and endocrine disorders can easily cause chloasma |
| inflammatory response | Pigmentation is easy to remain after acne marks and sunburn |
| genetic factors | Some people are born with slower metabolism of melanin |

According to recent popular discussions on social platforms (such as Xiaohongshu, Weibo, and Zhihu), the following methods have attracted much attention:
| method | Principle | Popular index (★) |
|---|---|---|
| Vitamin C | Antioxidant, inhibits tyrosinase activity | ★★★★★ |
| Niacinamide (vitamin B3) | Block melanin transmission and brighten skin tone | ★★★★☆ |
| Glutathione | Take orally or inject, directly decompose melanin | ★★★☆☆ |

In addition, quick whitening products may contain prohibited ingredients such as mercury, so you need to choose regular brands.
