Skin aging usually begins at the age of 25, becomes more pronounced at the age of 30, and worsens year by year thereafter. The aging process of skin is influenced by many factors inside and outside the body, such as genetics, nutrition, drugs, mental, light, environment and many chronic diseases, showing significant individual differences. Traditional wrinkle rejuvenation techniques have the disadvantage of not being able to balance efficacy and operation, so it is difficult to carry out widely.
In the early 1980s, with the introduction of the theory of selective photothermal action, medical laser technology has developed considerably. Especially in the 1990s, with the application of light peak energy control and repetitive short pulse technology, it can effectively remove the diseased tissue without damaging the normal skin, realizing the “no trace of disease”. In the past 10 years, different kinds of intense light and laser medical devices have been widely used in skin beauty treatment. It can be said that wrinkle rejuvenation has ushered in a new era.
Photorejuvenation – a new weapon for comprehensive skin quality enhancement
Photorejuvenation technology is a revolutionary technology for wrinkle reduction and skin rejuvenation. It has been introduced less than 10 years ago, but is rapidly becoming popular worldwide. It can effectively and conveniently remove various skin imperfections while improving skin elasticity, color and delicacy and rejuvenating the skin. The most important feature is that there is no obvious damage and it does not affect normal work and life.
1.Efficacy
●Removal or lightening of various freckles, pigmentation spots and age spots.
●Remove facial redness (capillary dilation).
●Improve fine wrinkles and make the skin delicate and smooth.
●Shrink enlarged pores.
●Thicken the dermal collagen layer and enhance skin elasticity.
●Eliminate or diminish acne marks.
●Reduces facial sebum and reduces acne and rosacea.
●Improves skin radiance.
●Promote the healing of surgical wounds and trauma scars.
2.Explanation
Photorejuvenation is the “twin” of hair removal technology. 10 years ago, a doctor named Bitter in San Francisco, USA first discovered that during laser hair removal, the skin in the area of hair removal became smooth and smooth. The skin in the hair removal area became smooth, and he conducted a lot of research on this. The results found that this is due to the skin tissue by the laser undergoes subtle changes and appear young, and found that the laser is not the most ideal light source, a certain wavelength of intense light is the most effective and safest light source. He then invented the technique of using intense pulsed light (IPL) to treat photoaging of the skin. Usually after about five exposures, the skin’s elasticity is enhanced, pigmentation fades, fine lines are reduced, and pores are minimized. When this treatment became available, it was immediately popular with Hollywood celebrities who flew to Dr. Bitter’s clinic in San Francisco to receive this amazing treatment. They also gave the treatment a very interesting name: Photo rejuvenation, meaning “skin rejuvenation light”, which was later translated as “photorejuvenation”.
The principle is that photo rejuvenation is a cosmetic treatment using intense pulsed light on the skin, which uses focused and filtered high-energy light in certain wavelengths to act on certain target tissues in the skin to achieve cosmetic treatment. It has two main functions, one is photothermolysis, that is, the shorter wavelength of light energy can be absorbed by the pigment and hemoglobin in the skin, lysing the pigment particles in the skin, coagulation of dilated capillaries, thus eliminating various skin pigment spots and eliminating facial redness; the second is biostimulation, that is, the longer wavelength of light can penetrate the deeper skin tissue to produce photothermal and photochemical effects The second is the biostimulation effect, that is, the longer wavelength light can penetrate the deeper tissues of the skin to produce photothermal and photochemical effects, so that the collagen fibers and elastic fibers of the skin can be rearranged and regenerated to restore skin elasticity, eliminate fine lines, improve pore size and skin roughness, and make the face glow. Because the energy density used in the treatment is very low, there are basically no side effects, so the treatment is very safe, and normal life and work can be carried out immediately after the operation.
3.Applicable groups
(1) Normal skin health care: fine lines and skin loosening, pore size that appear with age.
(2) Vascular lesions: capillary dilation, rosacea (erythema phase), skin heterochromia and erythema after laser grinding or other skin resurfacing procedures.
(3) Pigmented lesions: freckles, freckle-like nevi, coffee spots, chloasma, pigmented spots and seborrheic keratosis (age spots) with inconspicuous proliferation and flat appearance.
(4) Others: shallow depressed scar due to acne, chicken pox, etc.
4.Relative contraindications
(1) People who have recently received sun exposure and those who will receive sun exposure.
(2) People with photosensitive skin and those who are using photosensitive drugs.
(3) Those who have recently taken oral retinoic acid.
(4) Pregnant women.
(5) People with diabetes.
(6) People with keloid.
(7) Patients with suspected skin cancer.
(8) Patients with unrealistic expectations.
5.Course of treatment and postoperative status
(1) Treatment interval and frequency: Each treatment usually takes only about 20 minutes. Treatment is performed every 3 weeks, and the average number of treatments required to achieve the desired outcome is 3-6.
(2) Postoperative condition and care: After the procedure, there may be a slight burning sensation and slight redness, the burning sensation may last 0.5-2 hours and the redness may last 4-12 hours; for pigmented lesions, there may be temporary pigmentation of the pigmented area, which usually heals in 3-10 days after decabbing. The treatment does not affect work, so there is no need to take time off work.
After surgery, the treated area should be cooled with a cold pack for at least 15-30 minutes until the heat sensitivity subsides. Hot water cleaning should be avoided for a few days after surgery, and cold water should be used to gently clean the skin. Vitamin C synthetic cream and sunscreen should be applied in the morning, and moisturizer should be applied after cleaning the skin at night.
6. Factors affecting the efficacy
The efficacy of the treatment is related to 3 factors: the treatment physician, the treatment equipment and the customer’s response to the photon treatment.
An experienced treatment physician is a prerequisite for successful treatment. In the treatment process, the physician’s grasp of the indications and treatment experience is very important. Some people mistakenly believe that as long as they have the equipment they can achieve good results, in fact, the same equipment used by different physicians often has different results. It is best to choose a regular hospital, because these hospitals have strong technical strength, advanced equipment and technology, experienced treatment, and more importantly, a solid medical foundation, high medical reputation, and a clear diagnosis of the disease, so that the “right treatment” can be achieved.
Reliable equipment is the key. The efficacy and safety of different equipment varies greatly. The price of high-end international brand photorejuvenation equipment is more than a million RMB per unit, while many imitation products cost only tens of thousands of RMB, or even thousands of dollars.
The final issue to emphasize is the responsiveness of patients to photon therapy. You may see some patients with very good results that you envy, while others have very slow results, which is very normal and is due to individual differences. In general, skin color and skin responsiveness to photons are important factors in the effectiveness of treatment. An experienced practitioner can minimize this difference.
