How to remove melanin from the face

Under normal circumstances, facial hyperpigmentation may be caused by factors such as ultraviolet (UV) exposure, lack of sleep, malnutrition, acne, or melanosis. Treatments such as picosecond laser therapy, photorejuvenation, chemical peels (e.g., fruit acid peeling), or medication may be used under the guidance of a physician. It is recommended to visit a reputable medical institution and undergo procedures under professional medical supervision to ensure both effectiveness and safety. Detailed analysis is as follows:

1. UV Exposure

Prolonged sun exposure may stimulate melanocytes in facial skin due to UV radiation, leading to excessive melanin production. Sunscreen should be applied when going outdoors, along with protective measures such as umbrellas, hats, and sunglasses to reduce UV damage. Under medical guidance, picosecond laser treatment can also be considered. This method uses ultra-short pulsed lasers at picosecond durations to target pigmented areas, breaking down melanin particles and promoting skin metabolism to improve skin texture. The typical reference cost for picosecond laser treatment is 3,000–8,000 RMB per session. Improvement is usually observed within 1–2 weeks, although side effects such as redness and pain may occur.

2. Sleep Deprivation

Chronic late-night habits or insufficient sleep may disrupt normal skin metabolism, resulting in melanin deposition on the face. A comfortable and quiet sleeping environment should be maintained, avoiding late nights to improve sleep quality. Photorejuvenation may also be performed following a doctor’s advice, using specific broad-spectrum colored light to act on the skin, decompose melanin, and enhance skin metabolism. The typical reference cost for photorejuvenation is 1,000–3,000 RMB per session, with noticeable improvement generally seen within 7–14 days. However, possible adverse reactions include dryness and redness.

3. Malnutrition

Long-term dieting or nutritional imbalance may lead to poor nourishment of facial skin, triggering melanin production. Dietary adjustments should be made to ensure balanced intake of proteins, vitamins, and minerals, providing essential nutrients for the skin. Under medical recommendation, fruit acid peels may also be used. These peels promote exfoliation of the stratum corneum and accelerate skin metabolism to reduce pigmentation. The typical reference cost for fruit acid peels is 500–2,000 RMB per session, with visible improvement usually occurring within 7–10 days. Possible side effects include dryness and flaking.

4. Acne

Acne is primarily caused by oily diets or bacterial infections. Inflammatory responses from acne lesions may lead to post-inflammatory hyperpigmentation, causing the aforementioned symptoms. It is often accompanied by skin lesions and pain. Treatment options under medical supervision may include topical clindamycin hydrochloride gel, oral isotretinoin soft capsules, or traditional Chinese medicine such as Jiedu Acne Pills.

5. Melanosis

Melanosis may be associated with genetic factors or frequent exposure to chemicals. It can cause overactivity of melanocytes, leading to excessive melanin production on the face. Symptoms may include rough or atrophic skin changes. Treatment under medical direction may involve oral vitamin C tablets, hydroquinone cream, or vitamin E lotion.

Maintaining healthy lifestyle habits is important. Pay attention to skin cleansing and moisturizing, avoid chronic sleep deprivation or skin irritants, to support skin recovery.
