Introduction
In general, spot removal is mainly performed using laser technology, which utilizes the thermal effects of lasers to remove spots. The usual reference price ranges from 3000 to 8000 yuan per session, and visible improvement can typically be seen within 7 to 30 days. After spot removal, sun protection is necessary for several reasons, including preventing pigmentation, promoting skin repair, preventing inflammation, protecting the skin from photoaging, and maintaining the spot removal results.

Generally, spot removal is primarily achieved through laser treatment, utilizing the thermal effect of the laser to eliminate pigmentation. The usual reference price for this procedure ranges from 3000 to 8000 yuan per session, and visible improvement can typically be observed within 7 to 30 days. After spot removal, sun protection is important for several reasons: preventing pigmentation, promoting skin repair, preventing inflammation, protecting the skin from photoaging, and maintaining the effectiveness of the treatment. Here is a detailed explanation:

1. Preventing Pigmentation

After spot removal, the skin is newly regenerated and delicate, making it more sensitive to ultraviolet (UV) radiation. Without proper sun protection, UV exposure may induce melanin deposition, compromising the effectiveness of the treatment.

2. Promoting Skin Repair

Following spot removal, the skin requires time to recover and regenerate. Sun protection helps reduce irritation and damage caused by UV rays, thereby promoting natural skin healing.

3. Preventing Inflammation

After spot removal, UV radiation may intensify inflammatory responses in the skin, potentially leading to post-inflammatory pigmentation. Therefore, sun protection helps reduce inflammation and prevents the occurrence of pigmentation following inflammation.

4. Protecting Against Photoaging

Prolonged exposure to UV radiation can lead to photoaging, such as skin laxity and increased wrinkles. Sun protection helps shield the skin from these harmful effects.

5. Maintaining Spot Removal Results

Spot removal treatments are usually performed to improve skin appearance and texture. Sun protection reduces UV-induced skin damage, thus prolonging the duration of the treatment's effects.

If you plan to undergo laser spot removal, it is recommended to visit a reputable hospital and perform the procedure under the guidance of a qualified physician to ensure safety. After the treatment, it is essential to strictly follow sun protection measures to minimize UV damage to the skin.

Is laser spot removal safe?
Laser pigmentation removal works by utilizing the photothermal effects of lasers with different wavelengths to target and break down pigment particles in the skin, thereby achieving the purpose of removing pigmentation. The safety of laser pigmentation removal depends on the standards and practices of the medical facility. If the facility is legitimate and follows proper protocols, the procedure is generally quite safe. However, if performed at an unregulated or unqualified clinic, it may pose safety risks.

Will stopping the use of a pigmentation-removing product after a few days cause any harm to the skin?
Under normal circumstances, discontinuing the use of skin-lightening products after a few days generally will not cause significant harm to the skin. However, the specific effects should be evaluated based on the product's ingredients and the individual's skin condition. The risk associated with short-term discontinuation of正规 (standard/legitimate) skin-lightening products is usually low. However, if symptoms such as redness, swelling, or a stinging sensation occur, it is recommended to stop using the product immediately and begin moisturizing and repairing the skin. Consistently following a scientifically-based treatment regimen is important for effective pigmentation removal, and frequently switching products should be avoided.

How effective is photonic spot removal?
Photorejuvenation for pigmentation removal utilizes intense pulsed light with a broad wavelength spectrum to penetrate the skin's surface. The light is selectively absorbed by pigment particles, causing them to break down from heat and subsequently be expelled from the body through natural metabolism. This treatment also stimulates the production of new collagen, improving overall skin texture. The general reference price for photorejuvenation pigmentation removal is 1,000 to 3,000 yuan per session. Photorejuvenation offers good results and is a commonly used and effective method for removing pigmentation.

What is capillary dilation?
Telangiectasia is usually not an independent disease, but rather a clinical manifestation or symptom that may be caused by various factors. It refers to the thinning or dilation of capillary walls beneath the skin or mucous membranes, making the blood vessels more visibly prominent, presenting as red thread-like marks or reticular erythema. Proper skin protection should be practiced daily, including applying gentle sunscreen, wearing a hat, or using an umbrella when outdoors.

Is capillary dilation hereditary?
In general, whether telangiectasia is hereditary depends on its specific type. Some types of telangiectasia are associated with genetic factors and may be passed on to offspring, while telangiectasia caused by acquired factors typically does not have a hereditary component. For individuals with a genetic predisposition, earlier preventive measures are recommended in daily skincare, such as applying sunscreen from an early age.
