Laser Treatments

Diode Laser Details: A Diode laser is a semiconductor device that produces coherent radiation (in which the waves are all at the same frequency and phase) with a wavelength of 808nm it has a deep penetration and is attracted to the pigment in the hair and skin. It can be used on skin types 1-6 for hair reduction. Based on the selective photo thermolysis theory, laser energy is preferentially absorbed by melanin in hair, damaging the hair follicle which loses its ability to regenerate in varying degrees based on the hair growth stage. ​ Lasers remove hair though a process called Selective Photo Thermolysis in which energy in the form of wavelengths is delivered into the hair shaft and follicle. The light is attracted to and absorbed by the melanin and this heat up the tissue causing thermal damage to the follicle resulting in hairs weakening or not growing back.   At the same time, the unique sapphire contact cooling technology in the handpiece cools down the epidermis to prevent a burning sensation. Therefore, SDL-B Diode Laser Therapy System can be a less painful treatment and have permanent hair removal after 8-10 sessions.   The number of treatments can vary from person to person but usually 4-6 treatments will give you a reduction of up to 80-90% and then maintenance treatments 2~3 times a year. If there is a hormonal imbalance you may be required for more maintenance treatments. Depending on the area being treated it can be anywhere from 4-6 weeks in between treatments. The hair growth cycle on the face is usually four weeks while the legs is normally six weeks but this can vary from person to person.   Diode laser targets the pigment in the hair so the hair must be medium brown to black the darker the better, for best results. Behind the Diode laser technology you can also treat blonde, red grey or white hair. Due to the less amount of pigment within blonde, red grey or white hair, the results will be less impressive as the black hair.   This device adopts a continuous pulse output mode. Once appropriate parameters are set, treatment can begin by sweeping over the area to be treated. During the treatment process, the laser with 808nm wavelength penetrates epidermis and reaches the skin corneum layer and be absorbed by the melanin down to the hair follicle and surrounding tissues which is then turned from energy into heat. If hair is at the desired hair growth stage the follicle is damaged and ceases to grow. An Effective and quick slide treatment based on consecutive pulse output makes laser hair removal more safe, convenient and quicker.   Laser Selective Photothermic effect plays a decisive role in hair removal. As the fundamental theory for Diode Laser’s hair removal function, Laser Selective Photothermy makes the target tissues (melanin in follicle and hemoglobin in hair papilla nutrient vessels) shows perfect absorbency to specific wavelength. Treatment time for each pulse should be equal to or less than target issues’ thermal relaxation time. Thus photothermy effects will be limited in target issues, and prevent thermal energy’s damage to surrounding tissues. At the meantime, hair follicles will be effectively damaged and hair regeneration will be prevented. There is also no possibility for the formation of scars. This kind of effect is featured with degeneration of hair follicles, depigmentation of regenerated hair. While the hair follicles in the growing period have full pigmentation, it is easy for them to absorb laser beams in a certain wavelength so as to achieve the therapeutic objective. In consequence, Diode Laser Therapy System is safe and permanent for hair removal. With a wavelength of 808nm, Diode Laser Therapy System penetrates into the skin with a depth of 2.5mm. Its influences cover hair follicles in different positions with different depths. Scattered in hair follicles stromal cells, melanin will be transferred to hair shaft during the process of hair growth.   Melanin is rich in hair follicle epithelium, hair papilla, and hair cortex. Melanin selectively absorbs laser energy and the produced energy immediately forms local high temperature, which damages hair follicles and hair shaft, hinders and terminates hair growth. Laser energy tends to be easily absorbed by melanin in hair follicle and hemoglobin in dermal papilla nutrient vessels, and then producing photothermal effects. When the temperature in hair follicles rises to some certain degree, thermal expansion happened in hair follicle fractures melanin cells and be pushed out of hair pores by steams. At the same time, dermal papilla nutrient vessels are damaged because of hemoglobin solidification. Under above dual functions, effective hair removal will be achieved.   Therefore, Diode 808 is effective in the treatment of leg veins, other benign vascular lesions, hair removal, and permanent hair reduction. Laser has been around for a long time now and the technology is making treatments safer than ever. This Diode device is preprogrammed for specific skin types and different parts of the body as long as no contra-indications and pre and post care recommendations are followed, the risk of any side effects is minimal.     CO2 Laser Details Skin Rejuvenation Laser ​ CO2 Laser is Class 4 laser uses the theory of selective photothermy and decomposition integrating merits of both invasive and non-invasive treatment. CO2 fractional laser device has fast and clear curative effects, minor side effects and short recovery time. The treatment with CO2 laser refers to acting on skin with micro-holes; three areas including thermal desquamation, thermal coagulation and thermal effects are formed. A series of biochemical reactions will occur to skin and stimulate skin in self-healing. Skin firming, tendering and colored spot removal effect can be achieved. Since the fractional laser treatment only covers part of skin tissues and new macro-holes will not be overlapped. Thus, part of normal skin will be reserved, which quickens recover. ​ The CO2 Laser (10600nm) is indicated for use in surgical applications requiring the ablation, vaporization, excision, incision, and coagulation of soft tissue in dermatology and plastic surgery, general surgery. Dermatology, Plastic Surgery and General Surgery procedures Laser skin resurfacing Treatment of furrows and wrinkles Removal of skin tags, actinic keratosis, acne scars, keloids, tattoos, telangiectasia, squamous and basal cell carcinoma, warts and uneven pigmentation. It is also used in the treatment of cysts, abscesses, hemorrhoids and other soft tissue applications. Also in Blepharoplasty Site preparation for hair transplants. The fractional scanner is for treatment of wrinkles and skin resurfacing   Tattoos Removal ​ Q-Switched Nd:YAG Laser Therapy Systems is based on laser selective photothermy and blasting mechanism of Q-switched laser. Energy form particular wavelength with accurate dose will act on certain targeted color radicals: ink, carbon particles from derma and epidermis, exogenous pigment particles and endogenous melanophore from derma and epidermis. When suddenly being heated, Pigment particles immediately blast into smaller pieces, which will be swallowed by macrophage phagocytosis and enters into lymph circulation system and finally be discharged out of body. It is used for Tattoo Removal, Treatment of Vascular Lesions, Treatment of Pigmented Lesions, Incision, Excision, Ablation, and Vaporization of Soft Tissue for General Dermatology. ​ The 1064nm wavelength is used for Tattoo Removal of Dark ink: blue and black, Treatment of Pigmented Lesions such as Nevus of Ota ​ The 532nm wavelength is used for Tattoo Removal of Light ink: red, sky blue and green, Treatment of Vascular Lesions such as Port wine birthmarks, Telangiectasias, Spider angioma, Cherry angioma, and Spider Nevi. ​ The 532nm wavelength is used for Treatment of Pigmented Lesions such as Cafe-au-lait birthmarks, Solar lentiginos, Senile lentiginos, Becker's nevi, Freckles and Nevus spilus   Treatment effect differs from person to person. It is related to some factors including patient's age, body condition, skin problems, operation parameters etc. For those who do not have a significant improvement after one treatment, it can be considered to adjust the operation parameters, increase the times/passes of treatment appropriately, or prolong the treatment cycle.   Treatment cycle usually takes 30 minutes ​ To Q-Switched Nd: Yag Laser, different indications have different course and interval of treatment. For Nevus of Ota, each course of treatment consists of 2 - 8 sessions, repeated every 2 months. For Chloasma, each course of treatment consists of 4 - 10 sessions, one month apart. ​ Attention should be paid that intensive treatment will greatly increase the probability of the color fade and hypopigmentation Therefore, interval between treatments should not be less than 2 months, to give skin enough time to repair and rebuild.   ​ IPL IPL is Intense Pulsed Light Therapy Device treats skin with sunburn damage, freckle, age pigment, tiny wrinkle, angiotelectasis as well as in removal of unnecessary hair. The mechanism of treatment is based on light’s selective absorption effects.   The spectrum of Intense Pulsed Light Therapy Device is continuous which contains wide wavelength ranges. It selective light filtering scope is 690/560/420-1200nm. Ascertainable effects on skin include heat, machine, electromagnetism, photochemistry and physical stimulation. The working principle of IPL lies in treating benign lesion of skin pigmentation, vascular disease and hirsutism with IPL’s photothermal effects. Treating results are realized through different target skin cells’ (including melanin, hemoglobin, collagen, and water) absorbing ability for photothermy. The combination of short pulse width, low energy density and cooling system guarantee effective treating results without injuring normal tissues. Based on principle of selective photothermy, i.e. intense pulsed light with wavelength of 690/560/420 ~ 1200nm, which will be penetrated into derma, the abnormal pigment granules and block mass absorb light and pigments will be resolved. Some resolved debris will be peeled and remains will be eliminated out of body by phagocyte. After 5-14 days, hyperpigmentation will be lighter and become normal. Treatment principle of Intense Pulsed Light Therapy Device: Multi-wavelengths and colorful wide spectrums produced by Intense Pulsed Light penetrate into epidermis and reaches dermis. Acting on abnormal pigment cells and target vascular tissue, IPL dissolves abnormal pigments, closes abnormal vessels, and stimulates regeneration of collagen. Then, elastic fibers will be rearranged and effects of pigments removal and skin rejuvenation will be achieved. This treatment is targeted, symptoms pointed and energy sufficient. ​​ HR is used for hirsutism treatment and excessive hair removal; SR is used for exogenous and endogenous pigments removal such as blue, black and brown pigment lesions. VR is mainly used for abnormal skin vascular diseases treatment
