How to remove spots on hands

Generally, the appearance of spots on the hands may be caused by genetic factors, ultraviolet (UV) exposure, aging, endocrine disorders, eczema, and other reasons. Treatments such as general care, medication, laser whitening, microneedling whitening, and laser spot removal can be used under the guidance of a doctor. Specific analyses are as follows:

1. Genetic Factors

If there is a family history of pigmentation, the likelihood of developing spots in offspring also increases. In daily life, concealing cosmetics can be used to cover the spots. Laser treatment for pigmentation can be performed under the guidance of a professional physician. This method uses the principle of selective photothermolysis, where specific wavelengths of laser light target the pigmented areas. The laser energy is absorbed by the pigment particles, generating heat that breaks the pigment into tiny fragments, which are then naturally excreted through skin metabolism, achieving the goal of removing spots. The reference cost ranges from 200 to 5,000 yuan per session. Improvement is typically seen within 2–5 weeks, although side effects such as redness and pain may occur.

2. Ultraviolet Radiation

When the skin on the hands is exposed to UV radiation for prolonged periods, it stimulates melanocytes to produce excess melanin, leading to hyperpigmentation and the formation of spots. Daily sun protection is essential. It is recommended to undergo laser whitening under the supervision of a qualified doctor. This treatment uses specific wavelengths of laser energy to directly target melanocytes, breaking them down so they can be eliminated through natural metabolic processes, thereby lightening pigmented spots. The reference cost ranges from 3,000 to 10,000 yuan per session. Results are generally visible within 7–15 days, though possible side effects include post-inflammatory pigmentation and temporary redness or swelling.

3. Aging

As people age, skin metabolism gradually slows and the skin’s self-repair capacity declines, leading to abnormal melanocyte metabolism and the development of pigmentation. Maintaining healthy lifestyle habits and ensuring adequate sleep are important. Microneedling whitening, performed under professional medical guidance, may also be considered. This technique uses fine needles to create micro-channels in the skin around the lips (or other affected areas), stimulating the production of new collagen and elastin fibers while promoting the metabolism and elimination of melanin, thus improving pigmentation. The reference cost is generally between 1,000 and 3,000 yuan per session. Improvement is usually noticeable within 7–14 days, though mild pain or discomfort may occur.

4. Endocrine Disorders

Endocrine imbalances may result from factors such as high stress levels, staying up late, and irregular作息 (daily routines). Hormonal imbalances can disrupt melanocyte metabolism, leading to skin pigmentation and spot formation. Symptoms may include menstrual irregularities, mood swings, and insomnia. Patients should follow medical advice and use medications such as Wuji Baifeng Pills, Xiaoyao Pills, or progesterone soft capsules as prescribed.

5. Eczema

Eczema is an inflammatory skin reaction caused by various internal and external factors, including genetics, immune system abnormalities, impaired skin barrier function, environmental triggers, and allergens. Eczema can irritate melanocytes, resulting in post-inflammatory hyperpigmentation and the formation of spots. Symptoms may include skin redness, itching, and oozing. Treatment should follow medical guidance and may include topical or oral medications such as miconazole clotrimazole lotion, azithromycin tablets, or mupirocin ointment.

It is recommended to visit a reputable medical facility and receive treatments under the supervision of qualified professionals to ensure safety and effectiveness. In daily life, avoid prolonged UV exposure, maintain regular sleep and dietary habits, avoid excessive fatigue and stress, and pay attention to skin hydration and cleansing. Comprehensive lifestyle adjustments can effectively prevent and reduce the occurrence of hand pigmentation.
