What methods are available to remove age spots on the hands?

Normally, "senile warts" refer to seborrheic keratosis. Hand seborrheic keratosis may be caused by air pollution, friction irritation, improper use of medications, actinic keratosis, or Bowen's disease. It can be treated under a doctor's guidance with chemical peeling, cryotherapy, laser therapy, or medication. It is recommended to visit a formal hospital and undergo related procedures under a doctor's guidance to ensure effectiveness and safety. Detailed analysis is as follows:

1. Air Pollution

Air pollutants may irritate and damage the skin on the hands, causing seborrheic keratosis. Wearing protective gloves can reduce contact between the hands and pollutants. Under a doctor's guidance, chemical peeling can also be used for treatment. This involves using chemical agents such as salicylic acid and fruit acid to loosen and exfoliate the stratum corneum, promoting epidermal cell renewal and restoring smooth, delicate skin. The general reference price for chemical peeling is 500-1500 yuan per session, with visible relief usually occurring within 7-14 days, although symptoms such as skin pain and allergies may occur.

2. Friction Irritation

Frequent friction or irritation of the skin on the hands may cause thickening of the stratum corneum, affecting normal skin physiological functions and leading to seborrheic keratosis. One should avoid prolonged use of rough tools or objects that cause friction on the skin and appropriately apply moisturizing products to maintain skin health. Under a doctor's recommendation, cryotherapy can be performed, using low temperatures to induce necrosis and shedding of the affected skin tissue, promoting skin cell regeneration and repair to improve skin quality. The general reference price for cryotherapy is 100-500 yuan per session, with visible improvement typically occurring within 10-20 days, although symptoms such as pigmentation and scarring may occur.

3. Improper Medication Use

Long-term use of medications such as adalimumab injection, cytarabine injection, or vincristine sulfate injection may affect the normal metabolism and proliferation of skin cells on the hands, inducing seborrheic keratosis. Patients are advised to follow medical instructions for proper medication use to reduce side effects. Laser therapy can also be followed under a doctor's advice, using the photothermal effect of lasers to vaporize, carbonize, or coagulate the affected skin tissue, thereby treating seborrheic keratosis. The general reference price for laser therapy is 3000-6000 yuan per session, with visible improvement generally occurring within 1-2 weeks, although adverse reactions such as skin pain and swelling may occur.

4. Actinic Keratosis

Long-term exposure to ultraviolet radiation may cause actinic keratosis, increasing melanocyte activity, leading to hand pigmentation and cellular proliferation, thus increasing the risk of seborrheic keratosis. It is usually accompanied by symptoms such as erythema and papules and can be treated under medical guidance with medications such as diclofenac sodium gel, hydroquinone cream, or tacalcitol ointment.

5. Bowen's Disease

Bowen's disease is generally associated with factors such as drug abuse and human papillomavirus infection. It may lead to abnormal proliferation and differentiation of skin cells, resulting in the aforementioned symptoms. It may be accompanied by symptoms such as skin scales and crusts, and treatment can be administered according to medical advice with medications such as fluorouracil cream, imiquimod cream, or tretinoin cream.

When going outdoors, it is recommended to apply sunscreen and wear gloves or use sun protection items to reduce UV exposure, which helps maintain skin health.
