Detailed Photorejuvenation

in the past few decades, wrinkles rejuvenation surgery has undergone dramatic changes. Initially by grinding and chemical stripping technique, and then to laser resurfacing rhytidectomy . Despite the good effect, but the inflammatory reaction after surgery, redness of the longer, the main drawback is that the majority of yellow after 2-6 months there will be a significant pigmentation (significantly different with white, white is little pigmentation). Thus the above methods are difficult to promote the use of a large number.

1999 年 Bitter applications of a non-coherent intense pulse light (intense pulsed-light, referred to as IPL) treatment of photoaging found that the performance of photoaging, such as wrinkles, rough skin, irregular pigmentation, enlarged pores and telangiectasia , significant improvement. Then some other scholars, such as Go1dbery, also made a similar report, from opening a Photorejuvenation - the prelude to the treatment.

IPL (or simply light rejuvenation) technology is defined as the use of continuous intense pulsed light (1PL) technology In the low energy density means a non-ablative skin rejuvenation treatment. In short the use of a strong light source light to improve skin aging. The real IPL not only wrinkles, but improvements in skin texture, irregular pigmentation and telangiectasia, including all of the light aging. Application of IPL for skin rejuvenation therapy is a new non-exfoliative methods used in the treatment of very low energy density, and thus almost no side effects, patients do not even have to stop working, can immediately resume normal activities after surgery.

1. Photodamage classification

(1) A group of skin damage:

① If various pigmented freckles , senile plaques , etc.;

② vascular lesions such as telangiectasia, rosacea and so on.

(2) B group of skin damage:

including dermal and epidermal tissue structural changes, involving changes in the structure of collagen, such as wrinkles, large pores, and significant changes in elastic fibers and so on.

A single patient may exist in either group or B group - also has two types of lesions or disease. Suffering from severe skin aging and (or) light aging patients may have two lesions.

2. Photorejuvenation principle:

IPL is by filtering and multi-spectra, emission spectrum can range from 550-1200nm. A variety of wavelengths, limited by the low cut-off filter wavelength output.

(1) photothermolysis principle: the output of the IPL in the shorter wavelengths of light can be in the skin pigment and blood in the absorption of oxyhemoglobin preference, without undermine the premise of normal skin, the blood vessel coagulation, pigment, or pigment cell destruction group, decomposition, so as to achieve treatment of telangiectasia, pigmented spots of the results. A group which can be used for the treatment of light injuries.

(2) bio-stimulation: the output of the IPL in the longer wavelengths of light to penetrate deeper into the skin tissue and photochemical effects of light and heat generated effects, so that the collagen fibers and elastic fibers re-arrange and regeneration, restore flexibility, so as to eliminate or reduce wrinkles, shrink pores treatment. B group which can be achieved on light injury rejuvenation treatment process.

3. Indications IPL

photon Rejuvenation cure including light damage, photoaging, including a variety of skin disorders.

Ⅰ class Photorejuvenation:

① vascular lesions: telangiectasia, rosacea (erythema period) poikiloderma, and laser resurfacing after surgery or other skin erythema;

② pigmented lesions: freckles , coffee spot , melasma , pigmentation spots and obvious appearance of the proliferation of flat seborrheic keratosis (senile warts).

Ⅱ class Photorejuvenation: structural changes involved in collagen diseases such as optical damage, photo aging and skin wrinkles caused by loose, elastic fiber degeneration, large pores, as a result of acne, caused by chickenpox or smallpox scars and other shallow depressions.

4. Photorejuvenation contraindications

① recently received sun exposure and sun exposure will have to accept people;

② photosensitivity photosensitivity of skin and are used by drug groups;

; ③ A recent acid by oral administration of different dimensions;

④ pregnant women;

⑤ diabetes;

⑥ has a history of keloids;

⑦ patients with suspected skin cancer;

⑧ there are unrealistic expectations of patients.
