While treatment with BOTOX injection therapy can also be combined to eliminate dynamic wrinkles can also be used in conjunction with a number of skin care products, will enable more satisfactory effect of laser non-ablative wrinkles than rejuvenation, the use of intense pulsed light to light tender skin, the epidermis and dermis were greatly improved, rather than the ablative laser wrinkles rejuvenation, although a certain effect on wrinkles However, the pigment spots and telangiectasia and so is invalid.
1. Clinical efficacy
49 patients with different degrees of photoaging patients treated an average of 4.94 times per person, a total of 242 people treated the whole face. Points with a 1-9 scoring criteria to evaluate the treatment of skin before and after treatment of fine wrinkles, skin texture, skin laxity, irregular color Shen, pore size, telangiectasia, facial erythema and so improve the situation. The higher the score the more serious lesions of children were divided into mild :1-3 ,4-6 ,7-9 divided into moderately severe.
postoperative results showed:
① The light of all the appearance of aging skin there is a clear improvement. Wrinkle score decreased from 5.00 before treatment (moderate) improved to 2.83 points after treatment (mild to moderate). Improvement of 45.5% in patients more than 50%, 64% of patients more than 25%.
② skin texture that has some degree of improvement in 97.7% patients, of which 72% of patients more than 50% improvement.
③ pores to improve the situation is similar, with 97% of patients the appearance of pores have a certain degree of improvement, of which 67% of patients more than 50% improvement.
④ skin laxity score of 5.53 points from baseline (moderate) improved to 2.00 points after treatment (mild). All the patients skin laxity at least some degree of improvement.
⑤ telangiectasia show a high degree of improvement in results. Improvement of 70% of patients more than 50%, 38% of patients over a 75% improvement. The results show that patients of this technology can be achieved quite satisfactory. The overall appearance of all patients have been improved to some extent, of which 69% of patients had improved considerably. Overall satisfaction is quite high, 88% patient satisfaction, 61% of patients are very satisfied, 27% of patients very satisfied. 96% of patients willing to recommend this treatment to others.
30 patients treated in the subsequent study found that intense pulsed light to improve the degree of wrinkles ablative therapy although not as obvious. However, 25 patients in the eye, mouth and forehead week the Ministry of wrinkles or improved to a certain extent, of which nine patients had substantial improvement.
treatment of 238 patients, patients in the series after treatment, vascular lesions and pigmented lesions consequent improvement in a number of freckles , irregular pigmentation, appearance of the flat seborrheic keratosis, telangiectasia, rosacea, such as pores in the treatment of symptoms increased significantly reduce or even disappear, and the skin becomes shiny and elastic.
① The most obvious effect is freckles , after 1-3 treatments, 90% of patients achieved a significant effect (skin lesions subsided 60%), the cure rate after 5 (skin lesions subsided 90%) up to 85%, and 5 spots after a few more obvious with the use of laser treatment;
; ② look flat, no significant proliferation of the efficacy of seborrheic keratosis is close to freckles, irregular pigmentation efficacy somewhat less;
③ telangiectasia with 560nm and 570nm, 590 nm wavelength of the different treatment is also an ideal alternative, after 5 treatments, 85% of patients achieved a significant effect (skin lesions subsided more than 60%), 5 times the cure rate (skin lesions subsided more than 90%) In more than 50% of the lesions persist longer wavelengths of light can be used with a variable pulse frequency therapy or Nd: YAG treatment.
④ fine wrinkles, loose skin, coarse, large pores and so a certain degree of improvement. But for the thick skin wrinkles do not show a significant effect, with the application of 1 064nm laser treatment of low-energy density, the effect increased.
⑤ of melasma is hard to evaluate the efficacy of the current. Side effects; most patients than half an hour to several hours without significant side effects outside flushing, freckles and other pigmented lesions appeared a few days after treatment to deepen the color of the case slightly, about 1 week after that will go away freckles, etc. or reduced. 238 cases, only 4 (1.7%) of blisters scab (mainly occurred in telangiectasia patients), 7 patients (2.9%) had transient hyperpigmentation, and 2 cases (o.8%) occurred transient hypopigmentation.
2. Histological changes
line on the skin of patients after biopsy, the histological changes show: not only in the dermal papilla, and in the reticular dermis can be found in full-thickness The new collagen production; He also found that the superficial dermal inflammatory infiltrate and dermal papilla regression macrophages appeared in the phenomenon of black cells. The use of intense pulsed light and yellow light pulsed dye laser treatment of aging skin treatment article also reported on the histological changes of the skin, they found in the skin after collagen Ⅰ, Ⅲ collagen, elastin, and transparent quality acid, procollagen increased.
