In the field of skin beauty, pigmentation after laser treatment (commonly known as "anti-pigmentation") is a common problem. Asians have a higher melanocyte activity, and the probability of anti-pigmentation after surgery can reach 15%-30%. This article will conduct popular science from the aspects of causes, care, prevention and intervention methods, and focus on the application of intense pulsed light in pigmentation treatment.


ESSENCE AND CAUSES

The essence and causes of anti-pigmentation


When laser treatment destroys pigment or vascular tissue through thermal effect or blasting effect, the skin will activate defense mechanism to trigger inflammatory response, resulting in abnormal deposition of melanin and forming post-inflammatory pigmentation (PIH). Its depth is affected by the following factors:

Race and skin type: Yellow people have active melanin metabolism and are more prone to pigmentation.

Individual constitution: People with hormone fluctuations, sun exposure before treatment, abnormal liver and kidney function, etc. are at higher risk.

Postoperative care: Insufficient sun protection, use of photosensitive foods or irritating skin care products can aggravate pigmentation.


NURSING PRINCIPLES

Natural fading cycle and nursing principles of anti-pigmentation


Normal recovery process: Most people will shed scabs 6-7 days after surgery, and the skin will turn pink and gradually return to normal skin color.


Pigmentation fading time: Mild pigmentation usually fades in 3-6 months, and those with slower metabolism need 6-24 months.


Nursing key points:

·Strict sun protection: Use physical sunscreen (such as zinc oxide, titanium dioxide) or chemical sunscreen to block ultraviolet stimulation.

· Gentle moisturizing and repairing: Avoid makeup and irritating skin care products, and choose medical moisturizing and repairing products.

· Dietary adjustment: Reduce the intake of photosensitive foods (such as coriander, lemon, and mango), and vitamin C is recommended to be taken at night.

· Emotional management: Anxiety may promote melanin synthesis through the neuroendocrine system, so you need to keep a calm mind.


APPLICATION OF IPL

Application of Intense Pulsed Light (IPL) in Pigmentation Intervention


Intense pulsed light is a non-ablative phototherapy technology that produces selective photothermal effects on pigment particles by emitting a wide spectrum of strong light. It is one of the important means of clinical treatment of post-inflammatory pigmentation.


1. Mechanism of Action

Pigment decomposition:Light energy is absorbed by melanin particles and then broken into tiny particles, which are excreted from the body through skin metabolism or lymphatic circulation.

Inhibit melanin synthesis:Regulate tyrosinase activity and reduce melanin regeneration.

Repair skin barrier:Stimulate collagen regeneration, improve skin barrier function damaged after laser surgery, and reduce the risk of persistent inflammation.

2. Applicable scenarios

Superficial pigmentation:Applicable to pigmentation in the stable period 1 month after laser surgery (excluding active inflammation).

Comprehensive improvement of skin quality:While reducing pigmentation, it can improve skin dullness, fine wrinkles and other problems, achieving a youthful effect.

3. Operational characteristics and precautions

Mildness:Compared with Q-switched laser, the energy distribution of intense pulsed light is more uniform, causing less damage to the skin, and is suitable for sensitive skin or first-time treatment.

Treatment design:Usually 3-5 treatments are required, with an interval of 4-6 weeks. The specific number of treatments needs to be adjusted according to the severity of pigmentation.

Postoperative care:After treatment, it is necessary to strengthen moisturizing and sun protection, and avoid immediate exposure to the sun or the use of irritating skin care products.

Contraindications:Those in acute inflammatory period, with a history of photosensitivity, or those who have recently taken photosensitizing drugs should choose carefully.


OTHER METHODS

Other interventions


Topical medications:Depigmenting agents such as hydroquinone cream, azelaic acid, and retinoic acid ointments should be used under the guidance of a doctor to avoid irritation.

Fruit acid peeling:Promotes keratin metabolism through acidic substances. It is recommended to start with a low concentration (20%), once a month, and cooperate with home care to enhance the effect.

Low-energy laser:Such as Q-switched laser, it is suitable for deep pigmentation, but the energy parameters must be strictly controlled to avoid aggravating the damage.


KEY REMINDER

Key Reminder


Normal metabolic reaction and pathological pigmentation should be distinguished after laser surgery:

Physiological pigmentation:Short-term pigmentation within 1 week after surgery, often accompanied by dryness and desquamation, can disappear on its own.

Pathological pigmentation:If the pigmentation is not relieved after 1 month, you need to see a doctor as soon as possible to avoid the pigment entering the dermis and prolonging the treatment period.


In short, the darkening after laser surgery is not an "irreversible disaster". Through scientific care and professional intervention (such as intense pulsed light), most people can effectively shorten the recovery period. It is recommended to choose a regular medical institution and formulate a personalized plan after evaluation by a professional physician to avoid blind treatment and increase the burden on the skin.
