In the field of modern medical cosmetology, photorejuvenation, as a common non-invasive skin treatment technology, has received widespread attention. As people age, human skin gradually shows various aging symptoms from the age of 25, such as rough skin, enlarged pores, wrinkle formation, pigmentation, etc. These problems have prompted many beauty seekers to seek effective solutions, and photorejuvenation came into being.

TECHNICAL PRINCIPLES

Technical principles of photorejuvenation

Photorejuvenation, whose professional name is Intense Pulsed Light (IPL) technology, is different from the single wavelength characteristics of laser. Intense pulsed light selects a specific band between 500-1200nm, and achieves comprehensive improvement of various skin problems through precise adjustment of parameters such as energy, pulse, pulse width and delay time.

This technology is mainly based on photothermal and photochemical effects. Under photothermal effects, photons of specific wavelengths are selectively absorbed by pigment particles, hemoglobin, etc. in the skin, generating heat, thereby destroying pigment particles and closing abnormally dilated blood vessels; photochemical effects stimulate collagen fibers and elastic fibers in the skin, promoting their regeneration and reorganization, enhancing vascular tissue function, and improving skin microcirculation, thereby achieving the effects of shrinking pores, tightening skin, and brightening skin tone.

SUITABLE POPULATION

Applicable population

Including people with facial pigmentation problems such as freckles (hereditary or caused by sun exposure), sun spots, and chloasma. Intense pulsed light can use photothermal decomposition to accurately break up pigment particles, allowing them to be excreted from the body through metabolism, effectively fading spots and improving uneven skin tone.

Suitable for people with dilated facial capillaries. Intense pulsed light can close abnormally dilated blood vessels through photothermal effects, and use photochemical effects to enhance the function of vascular tissue, improve skin microcirculation, and relieve vascular skin problems.

For people who want to reduce hair, the specific band of intense pulsed light can act on the hair follicles, destroy the hair follicle structure, inhibit hair growth, and achieve the purpose of reducing hair.

Intense pulsed light has an inhibitory effect on Propionibacterium acnes and can reduce acne inflammation. In addition, it can also stimulate skin repair and has a certain improvement effect on acne scars left after acne healing.

Aging, ultraviolet radiation and other factors can cause wrinkles on the skin. IPL stimulates the regeneration and reorganization of collagen fibers and elastic fibers through photochemical action, increases collagen, fills wrinkles and grooves, improves skin firmness, reduces wrinkle depth, and improves skin condition.

TABOO POPULATION

Contraindications

Including but not limited to immune system diseases, liver and kidney dysfunction, severe cardiovascular diseases, etc. Such patients have weak physical functions, and IPL treatment may induce physical stress response, aggravate the condition, and even endanger life safety.

People who have experienced strong sun exposure within two weeks before IPL treatment are not suitable for immediate treatment. After exposure to the sun, the skin is in the stage of repairing photodamage. At this time, intense pulsed light is used, and the skin is more sensitive to light and heat, which can easily cause adverse reactions such as burns and blisters, affecting the treatment effect and skin health.

After intense pulsed light surgery, the skin's sensitivity to ultraviolet rays increases, and strict sun protection measures are required, such as using sunscreen and parasols. At the same time, attention should also be paid to skin moisturizing and repair. If the patient fails to follow these postoperative care requirements, it may lead to aggravated skin pigmentation, poor treatment effect, and even skin darkening.

SAFETY

Safety

Under standardized operation and professional medical environment, intense pulsed light is a relatively safe medical beauty technology. Professional doctors in regular medical institutions can reasonably adjust treatment parameters according to factors such as the patient's skin type and the severity of the problem, ensuring the treatment effect while minimizing risks. This technology is a non-invasive treatment with minimal trauma to the skin and fast recovery after surgery, which generally does not affect normal work and life.

However, if the treatment parameters are not set properly, such as too high a treatment frequency or too much energy, a series of adverse reactions may occur. Too high a treatment frequency may lead to aggravated skin photoaging; while too much energy may cause irreversible damage to the skin, such as skin burns, scar formation, or temporary pigmentation. Therefore, it is crucial to choose a medical institution with professional qualifications, experienced doctors, and medical equipment that meets the standards for treatment.

POSTOPERATIVE NURSING

Postoperative care points

After surgery, the skin's ability to defend against ultraviolet rays decreases, and pigmentation is prone to occur. Patients should avoid direct sunlight, and be sure to apply high-multiple sunscreen (SPF≥50) when going out, and use physical sun protection measures such as sun hats and parasols. Even indoors, be careful to avoid being near windows and other places where sunlight can shine for a long time.

2. Strengthen skin moisturizing and repair

After intense pulsed light treatment, the skin loses more water, and discomfort symptoms such as dryness and tightness may occur. Patients should use mild, non-irritating moisturizing skin care products, such as products containing hyaluronic acid, ceramide and other ingredients, to help the skin lock in moisture and promote the repair of skin barrier function. At the same time, the frequency of applying medical cold compress masks can be appropriately increased to relieve skin discomfort and promote skin recovery.

Avoid using highly irritating cosmetics and skin care products, as well as excessive cleaning and rubbing of the skin in the short term after surgery. Avoid eating spicy and irritating foods, quit smoking and drinking, so as not to affect the recovery process of the skin.

Intense pulsed light provides an effective means to solve a variety of skin problems, but when choosing treatment, patients should fully understand their own skin conditions and indications and contraindications for treatment, and carefully choose medical beauty institutions and doctors. Strictly follow the nursing requirements after surgery to ensure the treatment effect and skin safety and achieve the ideal skin beauty goals.
