[Definition
It is the phenomenon of skin aging caused by natural or unnatural factors. After birth, skin tissues become more and more developed and active, and when they reach a certain age, they start to degenerate, and this degeneration is often carried out slowly without people being aware of it. Skin growth period generally ends at about 25 years old, some people call this period “the bend of the skin”, since then growth and aging at the same time, the skin elastic fibers gradually thickened, 40-50 years old, the skin aging slowly and obviously, but the degree of aging varies from person to person.
Skin aging factors]
1, age factor: skin aging generally starts from about 30 years old, this is the only inevitable factor, the rest of the factors can be changed.
2, health factors: suffer from chronic wasting diseases.
3, mental factors: excessive use of the brain, too much thinking, mood boredom.
4, nutritional factors: nutritional disorders, lack of protein and vitamins.
5, lifestyle habits: staying up late, excessive fatigue and smoking. 6, environmental factors: long-term sun exposure, wind and rain, or seawater erosion.
7, endocrine disorders: women after menopause, estrogen secretion is reduced, thus affecting the fullness and elasticity of the skin.
8, improper skin maintenance.
9, improper medication: inappropriate drugs or cosmetics.
Skin aging performance]
1, skin tissue decline
The human epidermis is thickest at the age of 20, and gradually becomes thinner afterwards. Due to the aging cells attached to the epidermal stratum corneum, the skin surface becomes hard and loses its luster. The dermis is thickest at the age of 30, and then thins and atrophies. The subcutaneous fat decreases and the skin loses elasticity and tension due to changes in elasticity and collagen fibers, which further leads to skin laxity and wrinkles.
2.Low physiological function
The function of sebaceous glands and sweat glands declines, sweat and sebum are reduced, and the skin loses its luster and becomes dry.
Natural aging]
As the skin grows older, the skin aging that is not affected by external stimuli or less affected by external stimuli is called natural physiological aging. The skin is sagging, the appearance of small fine lines, dry skin, thinning, loss of elasticity, the appearance of damage is difficult to heal.
Photoaging]
The exposed parts of the skin are affected by environmental factors, such as sunlight, air temperature, air humidity and composition, which can also cause skin aging. The most important of these factors is sunlight, which is the main cause of unnatural skin aging.
It is manifested as sagging and hypertrophy of the skin with deep and thick wrinkles. Diamond-shaped skin with localized discoloration and dilated capillaries is seen on the neck. Sunlight causes skin aging and can also cause a variety of skin diseases. Photochemical damage is marked by degeneration of elastic tissue.
[The difference between photoaging and natural aging]
1.Change of skin thickness: photoaging damage is due to the accumulation of elastic substances and thickening, roughness and loss of elasticity. While natural aging causes skin thickness reduction and atrophy.
2.Change of elastin: There are a large number of thick and disorderly proliferated elastic fibers in the dermis of photoaging, and they become amorphous masses at the end; while natural aging has no such changes.
3, cellular changes: photoaging fibroblasts are hyperactive, and the number of inflammatory and mast cells in the dermis increases; while in natural aging, the vascular supply of the skin decreases, and the epidermal-dermal junction becomes flat.
4, changes in collagen: in photoaging skin, the number of mature collagen fibers decreases; while in natural skin aging mature collagen fibers become more stable.
【Treatment】
(I) Intense pulsed light treatment (photorejuvenation)
The function of photorejuvenation is to eliminate/lighten various skin pigmentation spots, enhance skin elasticity, eliminate fine wrinkles, improve facial capillary dilation, improve facial pore size and skin roughness, and also improve yellowing skin color, etc. The treatment principle of photorejuvenation is that the skin can be rejuvenated by pulsed light (intensivepulselight, IPL).
The treatment principle of photorejuvenation]
1. Biostimulation: The photochemical action of strong pulse light on the skin causes chemical changes in the molecular structure inside the collagen and elastic fibers of the dermis to restore the original elasticity. In addition, the photothermal effect it produces can enhance the function of blood vessels and improve circulation, thus achieving the therapeutic effect of eliminating wrinkles and reducing pores.
2, photothermolysis principle: because the pigment group content in the lesion tissue is much more than the normal skin tissue, the warming produced after the absorption of light is also higher than the skin. The difference in temperature between them makes the lesion blood vessels close and the pigment break down without damaging the normal tissue.
The people to whom photorejuvenation is suitable]
1.Spotty pigment spots on the face, whether sunlight or freckles, usually these spots give you a feeling of “dirty face”, although you often use powder to cover up, but always can not cover up.
2.Facial sagging, fine wrinkles and aging skin changes begin to appear.
3.Want to change the skin texture, hope the skin elasticity is better, the skin is smoother, improve the skin dull.
4.Rough skin, enlarged pores, acne marks, and dilated facial capillaries.
Photorejuvenation is not suitable for the following people
1.Patients who are photosensitive and those who have recently applied photosensitive drugs.
2.Pregnant women.
3.Systematic use of retinoic acid (at least 2 months after cessation of use before treatment). Such patients may have potential temporary weakening of skin repair function.
4, Melasma patients should be treated with caution, in most cases photorejuvenation does not solve the problem of melasma treatment, on the contrary, it sometimes makes the situation worse.
5.People with darker skin tone and prone to pigmentation should not use the method.
6.Patients who have unrealistic expectations of the treatment effect: Photorejuvenation is just an ordinary medical item, do not render and deify it, it has no ability to change the nature of the skin, do not have unrealistic expectations.
【Treatment process】.
1.Put on the goggles and keep your eyes closed throughout.
2, the physician will first apply a special cold gel to the treatment area, during the treatment, the photorejuvenation instrument’s treatment head guide crystal will be placed lightly on the skin to be treated and start releasing strong pulse light. At this time, you will feel slight pain.
3.After the treatment, you can wash the light guide gel with water.
4.Photorejuvenation usually needs to be done five times, once every three weeks, generally two to three times to see obvious results.
14 days care after photorejuvenation]
1, the first 1-3 days to reduce pain waiting for scab
After treatment, there will be redness, swelling, pain and tissue fluid exudation, about 24-72 hours after surgery, you can use topical antibiotic cream and cold compress.
2.Day 4-6 to relieve dry itch and reduce tightness
The way to relieve the dry itch is to make the wound moist, and you should choose something water-based. For example, moisturizing products. On the 6th day, the wounds are scabbed and you can wash your face.
3.Day 7-14 initial cleaning and efficient moisturizing
After the 7th day, the most important maintenance is cleaning and deep moisturizing. During this period, you can choose to deep cleanse by doing a cream moisturizing mask.
(II) Fractional laser treatment
Fractional laser technology is a new medical aesthetic technology and another milestone technology in the field of skin and plastic surgery. Fractional treatment has the advantages of fast and significant results of invasive treatment, but also has the advantages of non-invasive treatment with few side effects and short recovery time. It is a minimally invasive treatment between invasive and non-invasive.
Fractional laser treatment principle
Fractional laser is a minimally invasive treatment that uses a scanning motor to drive an oscillating mirror to instantly apply ultra-pulsed CO2 laser, which is 5 times finer (1/20th of a hair) than the energy of ordinary pulsed laser, to the skin tissue in different shapes in a uniform manner. These ultra-fine beams penetrate directly into the dermis, instantly vaporizing the tissue at the wrinkles or scars and sending a strong signal for collagen synthesis, which in turn initiates a series of skin reactions such as tissue repair and collagen rearrangement. The collagen then reproduces and regenerates, making the skin firm and radiant, smoothing wrinkles and scarring, and restoring elasticity.
Features of Fractional Laser]
Fractional treatment will only cover part of the skin tissue and the small holes will not overlap each other, so part of the normal skin is preserved and recovery is accelerated. Patients can return to normal life after 4-5 days. The treatment itself is safer and can treat any area. It is a minimally invasive treatment between invasive and non-invasive treatments. It has the dual effect of immediate cavitation and skin tightening and long-term stimulation of collagen production. The effect of traditional peeling treatment is fully achieved. Significantly shortens the recovery time after treatment. Precise adjustment of scan pattern size, density, shape, scan mode, diameter of micropores, penetration depth to meet the needs of various conditions.
Precautions and contraindications before treatment
1, scarred body.
2.Patients with severe diabetes, hypertension.
3.Patients with mental illness, or those who have high expectations of treatment.
4, active vitiligo and psoriasis, systemic lupus erythematosus.
5, during pregnancy or lactation.
6, those who are photosensitive.
7, those who have undergone chemical peels, abrasions and other skin resurfacing procedures.
8, those who have recently used retinoid drugs.
9. Patients who are unwilling to undergo post-operative sun protection and accept the risks of abrasion, etc.
Precautions for treatment]
Treatment site cleanliness: clean; 75% alcohol disinfection.
Safety precautions.
(1) Fully moisten 2 cm thick skim cotton with distilled water, then fully shield the guest’s eyes. (Do not directly irradiate the patient’s eyes, otherwise it will cause blindness)
(2) Operators must wear protective glasses and must not look directly at the laser with the naked eye. The treatment is painful and may be done without surface anesthesia if the pain is mild. Immediately after the treatment, the affected area will turn white or gray, or may turn red or blister lightly, and will turn into a scab after 2-3 days. After treatment (about 2 hours), if the treated area is hot and sore or swollen, apply ice packs or the specified repair cream. Avoid other cosmetics or masks. During the recovery period (after 2-3 days of treatment), repair cream must be applied consistently. If black dots appear on the treatment area, do not pick them and let them disappear naturally; pay attention to sun protection, do not apply irritating or therapeutic cosmetics, and minimize the consumption of food or drinks with high pigment content. Use special cleanser or regenerating cream for washing face or makeup. Sunscreen should be used for sun protection after scabbing. Use topical antibiotic ointment until the scabs fall off and avoid contact with water to prevent infection. Avoid sweating, sauna and strenuous exercise, which can be done after the scab has completely fallen off.
Unique advantages of fractional laser]
1.Full wavelength power
Compared with traditional laser, fractional laser is more powerful and can directly reach the deep dermis of human facial skin to stimulate the repair of damaged dermal tissues, so that the dermis can produce more collagen and rearrange it for skin rejuvenation effect.
2.Magic treatment without harm
The fractional laser can create micro-pores with a diameter of 120-1200 microns on the skin, with a hole spacing of 500 microns. These micro-pores can be closed within a day after treatment and are difficult to see with the naked eye.
3.Personalized treatment plan can be customized
The diameter and depth of the micropores can be adjusted during the treatment.
4.Obtained national safety certification
The most suitable laser for full-face treatment.
5.The skin can recover 3-6 days after treatment
The epidermis will heal completely within 8 hours after treatment, and you can wash your face and take a shower. 3-6 days or so, the scabs fall off and the skin returns to its normal appearance. And the internal collagen regeneration can be up to 6 months or even 6 years.
