What Are Podiatry Lasers?

Laser beauty is a new beauty method that has emerged in recent years. This method can eliminate facial wrinkles and make the skin tender and smooth with a proper amount of laser irradiation. Such as the treatment of acne, moles, age spots and so on. Laser beauty is popular because it is painless and safe.

The main principle of laser beauty products is the use of beneficial to the human body, strong penetration ability, high absorption rate of human tissues

a. Biological stimulating effect: The photochemical action produced by strong pulse light on the skin causes chemical changes in the molecular structure of collagen fibers and elastic fibers in the dermal layer to restore the original elasticity. According to experts

1. Lasers can be divided into:

solid-state laser; gas laser; liquid laser; semiconductor laser.

The advent of cosmetic lasers has provided new technical treatments for the field of plastic surgery, and also solved many problems that previous treatments could not solve. However, most cosmetic laser devices have entered China's medical industry in recent years because of their precise technology and high prices.

Lasers work by interacting with tissue. Lasers are divided according to what energy the tissue converts the lasers into;

Photothermal effect: Tissue converts laser light energy into thermal energy. Different tissues have different absorption coefficients, so lasers with specific wavelengths can be absorbed by certain tissues. This is the root cause of high laser selection, such as laser fine cutting, hemostasis. Remove facial wrinkles, etc .;

Light burst effect: Pulsed laser can generate high-impact shock waves, which can burst and crush tissues, such as laser damage to pigment particles;

Photochemical effect: The tissue converts laser light into chemical energy and produces chemical decomposition. Such as ArF excimer laser to correct corneal deformation;

Photodynamic effect: It is mainly used to treat tumors.

2. Laser beauty can be divided into:

(1) Laser to remove various pigments of facial skin, such as melanin (mole and tattoo), red pigment (hemangioma);

(2) Laser to remove skin defects such as moles, warts, pimples, neoplasms, benign tumors;

(3) Laser to remove excess body hair permanently;

(4) laser to remove facial wrinkles;

(5) Use laser knife instead of scalpel to carry out fine, minimally invasive and bloodless plastic surgery.

Photoaging skin is a manifestation of skin photodamage, which is mainly the result of cumulative effects of long-term exposure to ultraviolet radiation, manifested as light to deep skin wrinkles,

As we all know, it is still in an irregular and immature stage of development. The industry management lacks strength. The industry competition is in a disordered state. The operation of various beauty salons has not yet formed scale. All kinds of problems are intricate and interdependent, and it is even difficult to sort out the clues for a while. It should be said that this is the confusion faced by the entire industry. The combination of many factors makes it difficult for the entire industry to reach a certain level of credibility in society. Therefore, it is imperative to promote and implement the concept of scientific chain operation in the beauty industry, provide high-quality products and services, establish good working procedures, and form a good reputation and brand operation mode. Chain operation will be the mainstream of the future development of the beauty industry. As a modern business investment operation mode, chain operation will definitely become the main business direction of the beauty industry in the future. This Peugeot chain management concept will lead the entire industry into a new era of healthy and vigorous development.

1. What is compound IPL to remove acne

Composite IPL is a brand new green treatment method. Using unique photothermal treatment technology, photothermal energy efficiently kills

The principle of laser removing moles is to place the huge energy of the laser in an instant.

Laser hair removal principle:

The principle of laser hair removal is the principle of selective thermodynamics. (That is, the selected wavelength only affects melanin but not normal skin tissue, and the selected pulse width only affects melanin in hair follicles but not melanin in basal layer of skin.) There are abundant melanin in hair follicles and hair shaft Melanin is distributed between the cells of the hair bulb matrix and can also be transferred to the structure of the hair shaft (such as the medulla, cortex, and hairy skin). Lasers in laser hair removal can target melanin precisely and selectively for hair removal treatment. After the melanin absorbs the energy of the laser, the temperature rises sharply, which leads to the destruction of the surrounding hair follicle tissue and removes the hair.

Laser hair removal is multi-wavelength, which can selectively remove hair of different parts and different depths. The laser in laser hair removal often has only one medium wavelength, which has limited effective penetration and can only be treated for a certain type of skin. The effect on another type of skin is limited, and all hair removal lasers are four-level lasers, which are very dangerous to human eyes and soft tissues.

Ready to work

1. Do not use hair removal cream, hair removal cream and other cosmetics before laser hair removal. Wash yourself before removing hair.

2. First determine the location and range of hair removal. Because hair removal is permanent, only a certain range of hair removal can have a cosmetic effect.

3. There is a certain warm feeling when the laser light passes through the skin. This is a normal phenomenon. Physicians who are particularly sensitive will selectively use a little surface anesthetic, and the beauty seeker can complete the hair removal in a pleasant way.

4. After laser hair removal, the doctor will cold apply the hair removal area for 10 to 15 minutes. The hair removal area should be protected from the sun.

Lasers include helium-neon lasers, argon-ion lasers,

1) Technical principle

After laser irradiation, it will produce photothermal effect, photochemical effect, pressure effect, electromagnetic field effect and biological stimulus effect on the skin tissue, so that the damaged dead tissue in the skin scar is quickly pyrolyzed, gasified, or broken into tiny fragments, which will be broken into the body. Phagocytic cells are excreted after phagocytosis, thereby achieving the purpose of calming scars.

2) Adaptation and contraindications

Adapt to the crowd: patients with mild scars.

Contraindications

a. People with scar constitution;

b. Impaired coagulation mechanism, low immune function, chronic wasting disease, systemic or local infections;

c. People with photosensitivity;

d. People with various mental and psychological disorders and endocrine disorders should be used with caution;

e. Lupus erythematosus and vitiligo are used with caution in those who use hormones, salicin, and photosensitive drugs within 1 month.

3) Technical methods

Before treatment, clean the face, mark the scope of scar repair, do local infiltration anesthesia, turn on the power to preheat the laser, test the appropriate parameters before testing 1-2 spots in the lesion to observe the reaction. After no adverse reactions, treat the acne scar. The area was treated with laser, and after the treatment, it was wrapped with sterile gauze.

4) risks and complications

Pigmentation: The mechanism of pigmentation is not completely clear. Most people think that this phenomenon belongs to secondary pigmentation following inflammation, which is related to factors such as excessive sunlight exposure and deep skin tone after treatment.

Superficial scars: may be caused by excessive treatment dose or repeated irradiation in the treatment area, excessive cooling head temperature, insufficient skin cooling, and improper self-care after surgery. When scars are found, they should be treated in time.

Infection: After treatment, erythema exudate may occur if the wound surface is broken due to scratching or water pollution. Once infection occurs, seek medical treatment as soon as possible to promote the healing of the wound as soon as possible, but superficial scars may remain after healing.

Itching: Rarely, it may mean wound healing, but also be alert to the possibility of infection.

5) Treatment course and recovery time

The speed of laser treatment for scars depends on the area of the skin to be treated. Generally speaking, the duration of each treatment is not longer than 20 minutes, but it may be necessary to treat twice a week for a total of more than 8 times. After treatment, the skin color will become closer and closer to normal skin color, and some will be darker than normal skin color. After several months of recovery, it will be similar to the original skin color.

6) Precautions

Keep the wound clean and dry after surgery to avoid contamination of the wound with water or cosmetics. Avoid strenuous exercise,

In case the wound is pulled apart.

The wound is naturally exfoliated. Do not forcibly remove the epidermis to prevent hypertrophy of scars.

Avoid sun exposure after the peeling of the scalp skin. Photosensitivity drugs and foods are prohibited, and sunscreen can be applied to prevent pigmentation.

Pay attention to prevention and treatment of complications such as infection, scar, pigmentation and purpura.
