What should I do about yellowish or dark skin?

When the skin becomes yellowish or dark, it is important to first identify the cause, which may involve various factors such as diet, lifestyle habits, ultraviolet radiation, or underlying medical conditions. To address these factors, adjust your diet by consuming more fruits and vegetables rich in vitamins; pay attention to skincare, avoid prolonged exposure to UV rays, and use sunscreen when going outdoors; maintain healthy lifestyle habits by avoiding late nights and excessive fatigue; if the discoloration is caused by a medical condition, seek timely medical treatment.

In addition, consider using skin-whitening products or undergoing cosmetic treatments such as photorejuvenation to improve skin tone.
