Introduction
Laser pigmentation removal utilizes laser energy of specific wavelengths to precisely target pigment particles in the skin, breaking them down so they can be metabolized by the body, thereby eliminating spots. The general reference price for laser pigmentation removal is 2000–6000 yuan per session, and visible improvement can usually be seen after 1–3 months. With appropriate treatment and proper post-treatment care, hyperpigmentation recurrence generally does not occur.

Laser spot removal utilizes laser energy of specific wavelengths to precisely target pigment particles in the skin, causing them to break down and be metabolized by the body, thereby removing spots. The general reference price for laser spot removal ranges from 2000 to 6000 yuan per session, and visible improvement can usually be seen after 1 to 3 months. If the treatment is appropriately performed and proper post-treatment care is followed, hyperpigmentation (re-darkening) generally does not occur. However, if the treatment is improperly administered or post-treatment care is inadequate, hyperpigmentation may develop.

After laser spot removal, hyperpigmentation typically does not occur if treatment parameters are appropriate and post-operative care is properly managed. During laser treatment, the physician can precisely control the energy levels, keeping skin irritation within a manageable range. Patients should strictly avoid sun exposure after the procedure to prevent excessive ultraviolet radiation, as UV rays can activate melanocytes and increase pigment production. Additionally, following the correct use of post-treatment skincare products as instructed usually prevents hyperpigmentation, leading to gradually more even and fair skin tone.

However, if the energy settings used during laser treatment are too high, causing excessive damage to the skin, the skin's natural repair mechanisms can be affected. Melanocytes, when excessively stimulated, may secrete large amounts of melanin to protect against external damage, resulting in hyperpigmentation. Moreover, failure to protect the skin from sunlight after the procedure and prolonged sun exposure can also increase the likelihood of hyperpigmentation.

In daily life, the skin is relatively sensitive after laser spot removal, so it is important to avoid using cosmetics or skincare products that are strong or irritating, as they may interfere with the skin's healing process. Maintaining proper skin cleanliness and hygiene is also beneficial for recovery.
