In daily life, inadequate skin care can lead to yellowish discoloration of the skin, significantly compromising facial aesthetics. What causes skin yellowing, and how can it be improved?

Causes and Improvement Strategies for Skin Yellowing

Skin yellowing is commonly caused by prolonged exposure to ultraviolet (UV) radiation, resulting in excessive localized melanin deposition. Laser treatment is an effective option for achieving brighter, more even-toned skin. This procedure utilizes the photothermal effect of lasers to penetrate deeply into the skin, breaking down excess melanin while simultaneously stimulating collagen production—thereby promoting skin lightening and rejuvenation.

Skin yellowing may also stem from chronic selective eating habits, leading to systemic nutritional deficiencies and insufficient nutrient supply to the skin. In such cases, intravenous whitening injections may be beneficial. These injections contain active whitening agents that, upon administration into the epidermis, rapidly penetrate into the dermis and effectively inhibit melanin synthesis—promoting gradual skin lightening and tone improvement.

In daily life, incorporating vitamin C–rich foods into your diet can help brighten the skin and suppress melanin production. Avoid prolonged sun exposure, especially during peak UV hours, to prevent hyperpigmentation. When outdoors, use umbrellas or wide-brimmed hats for sun protection. Additionally, consuming ample fresh vegetables and fruits helps replenish essential nutrients required for healthy skin. We hope this information proves helpful!
