Laser treatments for treating skin conditions are continually evolving, and newer types of treatments that use light sources to treat skin disorders are also emerging. Among them is is Laser Photo Rejuvenation which uses state of the art energy devices and equipment to treat problems ranging from acne and acne scars, to rosacea, skin lesions, birth mark, tattoo and hair removal.
Laser Photo Rejuvenation in Dubai is gaining increasing popularity due to its quick results and small recovery time. The new techniques are not as invasive as the traditional lasers, hence making them a safe and effective option for prospective patients.
Photo rejuvenation involves the use of an energy-delivery device to improve skin texture, wrinkles, scars, fine lines, hyperpigmentation (discolouration as a result of sun spots, age spots and freckles). Photorejuvenation falls into three main categories:
Mechanical methods consist of lasers, thermal include thermage and chemical include chemical peels.
These are energy-delivery devices with very specific applications. There are a lot of different lasers each of which has unique characteristics such as wavelength, power and length of pulse duration, tailored to a particular kind of skin problem. Each kind of laser uses a specific wavelength of energy applied to a specific area of the skin for a select type and severity of the condition. Thus more than one laser might be required to achieve optimal results especially with multiple areas of concern.
Various effective types of treatments are available for acne. Lasers including CoolTouch and Smoothbeam have been used effectively for acne management. They are often used in addition to topical as well as oral medications already prescribed by the patients physician.
Few non-invasive treatment options are there for treating acne scars, and often the improvements are minimal. Previously acne scarring was treated through chemical peels and dermabrasion with varying results. However acne scars can be most effectively treated with laser photo rejuvenation.
The traditional CO2 lasers or second generation of erbium/YAG lasers were effective but produced side effects. The recent third generation erbium and YAG-CO2 combination laser has been effective for acne scars but without the side effects of the older laser types. Recently introduced for this treatment is the highly effective Fraxel Laser, named as such because it was designed to treat a fraction of the skin’s surface at a time, in thousands of tiny yet deep treatment areas but leaving surrounding skin untouched
The use of Intense Pulsed Light (IPL) energy device is also practiced by some for the treatment of rosacea, while others use the pulsed dye laser both with positive results but different side effects such as possible bruising with the pulsed dye layer.
Lentigos are dark areas of skin discolouration and resemble age spots or sun spots. Some forms of lentigo may also be considered as premalignant. Lentigines have been treated with various methods such as with the frequency doubled Nd:YAG (KTP) laser, Q-switched Nd:YAG Laser, Q-switched ruby, intense pulse light or alexandrite laser.
These are lace-like webs of tiny dilated red, blue, purple or red capillaries arterioles or venules that are visible just under the skin surface. The pulsed dye laser and intense pulse light have proven to be useful for matted telangeictasia or other small blood vessels. Localized tenalgiectasia and isolated vessels are usually treated with a frequency doubled Q-switched Nd:YAG (KPT) laser. Larger areas of the condition can be treated with pulsed dye laser or longer pulse V-beam dye laser.
These have a core group of blood or lymphatic vessels with dilated surface vessels or blebs like tiny blood blisters. Cherry angiomas and spider angiomas are treated with the pulsed dye laser or KPT.
These flashlamp-pumped dye laser or pulsed dye laser has been known to treat vascular lesions with small diameter blood vessels close to the skin surface such as vascular birthmarks.
Port wine stains are vascular birthmarks that do not leave without treatment. They respond well to longer-pule duration dye lasers (V beam etc.) as well as flashlap-pumped dye laser
Injection sclerotherapy which is injecting a solution into the vein to force it to close and turn into scar tissue that fades from view has been the choice of procedure for treating spider veins that are large enough to get a tiny needle into. Currently pulse dye and KTP lasers and intense pulsed light (IPL) therapy can successfully minimize the appearance of many unseemly blood vessels and needles and with fewer side effects or risk of getting scars.
Most professional tattoos or ones that are self-applied regardless of their colour can be removed successfully through Q-switched ruby, alexandrite or Nd:YAG lasers. Blue and green colours respond better to the Q-switched alexandrite laser. All every case several treatments are required at no more than four week intervals to allow proper healing between the treatments. Some patients might experience hypopigmentation (skin colour lightening), mild scarring or unfinished tattoo ink removal.
Pulsed dye laser and or intense pulse light treatments can effectively improve the appearance of vascular birthmarks such as port wine stains. Multiple treatments are required for maximum lightening at intervals of two months.
Nd:Yag laser treatments are a good option for permanent hair reduction in darker skin types and other laser wavelengths and IPL treatments can also be used with positive results. For instance the 810 diode laser and alexandrite laser are great options for every skin type except dark skin. Multiple treatments are required for maximum long-term hair removal. Hair removal treatments in 2004 totaled to 900,000 sessions indicating the popularity of this cosmetic procedure and the reason why so many laser hair removal med spas have emerged.
IPL systems have proven to be very useful in treating sun damage, large pores and hyperpigmentation. The Fraxwel laser has also proven to be useful in improving the appearance of brown spots, large pores and age spots.
Skin Irregularities, Dark Skin Discolouration and Fine Lines:
CO2, erbium/YAG and combination CO2-erbium/YAG lasers have been effective in treating wrinkles, acne scars, skin irregularities and certain kinds of skin discolouration. The Fraxel Laser has also been successful in improvement of fine lines and acne scars.
IPL or pulsed dye lasers are used for aging skin and sun damage. However the level of lasting results and length varies from patient to patient.
A combination of ILP and frequeny-doubled Q-switched Nd:YAG (KTP) laser is effective in treating pigmented lesions. In some cases topical therapy can be part of te treatment plan. Removal of dark moles by laser treatment is not recommended.
Kligman’s formula which is an ointment containing hydroquinone, tretinoin and dexamethasone followed by frequency-doubled Q-switched Nd:YAG (KTP) laser or IPL has effectively managed melasma, a patchy or generalized dark or tan discolouration of skin. Another potential treatment for melasma is the Fraxel laser.
Post-traumatic hyperpigmentation can be treated well with the frequency-doubled Q-switched Nd:YAG(KTP_, ruby laser, ILP or alexandrite.
Skin aging includes one or more elements such as loss of volume, loss of elasticity, or droopiness of the tissues that causes wrinkling and surface discolouration. Besides ablative removal treatments such as dermabrasion, laser resurfacing and chemical peel, non-ablative are many with many approaches such as IPL, low-level laser, radio frequency devices and infrared light.
The treatment for sagging skin and wrinkles from these photo rejuvenation treatments are still subject to investigation as the technology is continuously evolving and the number of doctors with extensive expertise in this specific area is limited. At the same time certain energy-delivery devices may assist with a particular element. One of the state of the art radio frequency devices may lift a brow two or three millimeters and delay the required brow-lift surgery. However the longer-lasting and effective repair of sagging skin without a surgical operation is difficult to attain so far. The best and most efficient fine surface wrinkle treatment is performed with the erbium YAG and/or the CO2 combination laser, but this requires anesthesia and a week long time for healing.
It has been reported that IPL therapy does help in collagen and elastic fibre production. Collagen supports fibroblasts which act as bridges of support for the skin just underneath the surface of the skin. Collagen production reduces as we age so the stimulation of collagen production through lasers or light therapy can help in reducing the effects of aging on our skin.
Thermage is another type of energy based device. It has been approved by FDA for improving the appearance of sagging skin on the face, smoothing wrinkles and improving facial contours.
Keloid and hypertrophic scars (abnormally large scars) can respond to 585-nm pulsed dye laser (PDL) treatments. Raised scar edges will need an additional laser such as CO2 laser system or Er:YAG. Resurfacing lasers have been known to improve surgical scars. However the results for surgical scar reduction cannot be compared to results for other types of more superficial or smaller scars. As mentioned earlier Fraxel Laser can drastically improve acne scars.
Since laser photo rejuvenation is a fairly recent and new technology that continues to evolve the level of expertise in using tem varies from doctor to doctor as does the availability of different technology. Patients are advised to ask their surgeon how many times they have performed the procedure, how often the patients have had side effects and how many treatments are estimated for their particular case and how long it is expected to last.
The use of laser photo rejuvenation in Dubai requires extensive training and expertise. Surgeons are generally trained to use a specific laser by the equipment manufacturer. Certification may require attending a training course, but this does not provide the physician with hands on experience. The doctors training and experience to use the specific energy delivery device or laser should be reviewed by a group of experienced peers. To a great degree, the results depend on the technique and experience of the doctor. Certification is not a guarantee of a successful outcome but the type of certification can better identify the training and specific education a doctor has to properly use the equipment.
