Overview
An injury heals in the presence of tension, hypertrophy often ensues. This condition is characterized by deposits of excessive amounts of collagen, as previously explained, giving rise to a raised scar. Understanding the role of tension in the development of a scar is essential to designing a successful treatment strategy. If there is significant hypertrophy or contracture present in a scar, surgical intervention is necessary to relieve the tension or there is a high likelihood the scar will reform. After tension relief, hypertrophic and contracture scars are more elastic with new remodeling of collagen and are more amenable to treatment with laser. However, if a scar has had initial fractional laser therapy this often makes surgical intervention easier to perform because the fractional laser therapy helps to create thinner collagen bundles.
LASER THERAPY FOR BURN AND TRAUMATIC SCARS
Erythematous scars (reddened scars caused by a dilation of superficial blood vessels in the skin, or erythema), and hypertrophic scars (scars with excessive deposits of collagen that cause a raised-scar appearance) are seen frequently in the first year after injury. Vascularspecific lasers and light devices, especially the 595-nm pulsed dye laser (PDL), are already well established for such applications. PDL is often combined with fractional laser therapy—either in the same treatment session or in alternating sessions.
Hypertrophic burn and traumatic scars are best improved by ablative fractional lasers. Ablative lasers, when compared to other lasers, have a significantly greater potential depth of thermal injury. One such laser modified for the treatment of scars reaches 4.0 mm in depth. Furthermore, tissue ablation appears to induce a modest immediate photomechanical release of tension in some restrictive scars. An appropriate degree of surrounding thermal coagulation appears to facilitate the subsequent remodeling response. To determine the appropriate laser pulse energy settings (treatment depth), scar pliability and thickness is estimated by the physician through palpation, or physical exam by touch.
Pigment-related abnormalities of scars (hypopigmentation, or a lack of coloring; hyperpigmentation, or darkening; and depigmentation, a loss of pigment) can also be improved with fractional therapy. Flat or atrophic scars from burns and trauma also respond well to fractional laser therapy. Atrophic scars are dermal depressions that occur due to collagen destruction during an injury. The goal of laser treatment for atrophic scars is to stimulate collagen production within the atrophic areas. Neocollagenosis, or collagen production, is most stimulated by fractional laser therapy, making it the best choice for flat or thin scars.
Special Treatments
OPD means an Out Patient Department of a hospital. It is the section of the hospital where patients are provided medical consultations and other allied services.
It's a type of surgery that moves hair you already have to fill an area with thin or no hair. Doctors have been doing these transplants in the U.S. since the 1950s, but techniques have changed a lot in recent years.
Laser Hair Removal is the process of removing hairs by beaming the highly concentrated light into the hair follicles which destroys the hairs. Lasers are useful for removing unwanted hair from the face, leg, underarm and other areas.Now Laser Treatment in Ganganagar is Possible.
Hair loss often is a result of different causes like heredity, anaemia, nutritional deficiencies, stress and medical problems like thyroid disorder, diabetes mellitus and polycystic ovarian syndrome (in females).
Acne scars are permanent textural changes and indentations that occur on the skin as a result of severe acne. The term “scarring” is not used for the temporary red and brown marks left early after acne has occurred as these marks will almost always improve without treatment.
Skin lesion removal includes mole removal, skin tag removal, milia removal, cyst removal and wart removal – for practical or cosmetic reasons you may not be covered by the NHS. Methods and prices vary depending on the size, placement and depth of the lesion.
Tattoos are fashion signs of younger generation. Also as a part of tradition, people in country side invariably have their names or images on their forearms, chest or shoulders and even a permanent dot as a Tikka in their fore head.
Skin pigmentation marks are a build up of melanocytes (cells containing melanin) under the skin typically referred to as freckles and age spots on the hands, face and body areas. Different types of laser can be used depending on the type of pigmentation.
This technique is known as skin polishing procedure or microdermabrasion – if the word would be broken up, it would consist of three parts – micro, derma and abrasion. Derma refers to the skin and abrasion is a method by which the dead skin cells of the skin are rubbed away.
The most dreaded biological change for most people is ageing. Ageing is inevitable, but it can be delayed and managed using highly efficient Anti Ageing Treatment solutions from a trusted source. Apart from the natural pace of aging, there are several extrinsic and intrinsic factors that contribute in accelerating the process altogether.

FRACTIONAL LASER TREATMENT: WHAT TO EXPECT
Any part of the body may potentially be treated with fractional laser therapy. The majority of fractional laser treatments can be performed in the clinic setting using a commercially available topical cream anesthetic preparation, which is applied under occlusion, or covered, 1 hour prior to treatment. Some patients may benefit from systemic preoperative analgesics (pain medication) or anxiolytics (anxiety medication). Conscious sedation or even general anesthesia can be employed in instances of large surface area involvement or anticipated poor patient tolerance of the procedure while awake. This is a particularly important consideration in children, as multiple treatments are usually required and children do not tolerate repeated painful interventions well. Patients experience minimal to no postoperative pain and little post-procedure downtime, resuming most normal activities after 48 hours.
With previous discussion in mind, fractional laser treatment technique, parameters, and adjunctive treatments should be applied thoughtfully to minimize the degree of cumulative thermal injury to the tissue. Each treatment is customized at every session according to individual scar characteristics and interval changes.
LASERS FOR MATURE SCARS
Fractional lasers are not only effective on new scars. Mature scars, whether 1 or 60 years old, all respond well to laser therapy. For the past decade we have treated scars of all ages. A minimum treatment interval of 2 to 3 months between fractional laser treatments is recommended to give the compromised scar tissue time to heal. Even after just 1 treatment session, a patient may continue to have improvement for many months up to 1 year.
Problems associated with mature scars include burning, itching, pain, discomfort, disfigurement, contracture, and limits to form and function. Fractional laser treatments have been successful not only in the appearance of scars but improving range of motion, while fractional ablative lasers also can have dramatic improvement in pain, itching, and burning.
Traditionally reconstructive efforts have been delayed until 1 year after injury, at which point many patients have formed hypertrophic scars and have significant decrease in range of motion. In fact, burn and traumatic scars worsen during the proliferation of wound healing between 3 and 7 months after injury. Early anecdotal evidence suggests that using fractional ablative laser in the early phases may improve wound healing and decrease hypertrophic scar formation. The discrete ablative columns likely have various wound-healing advantages, including novel laser photomicrodebridement, biofilm disruption, and stimulation of deep dermal cells. Fractional lasers in photo-aged (sun- or UV-damaged) and scarred skin have been shown to stimulate growth factor secretion, increase collagen production, and improve the cosmesis of skin, while producing negligible local trauma. This provides a unique opportunity in this patient population to improve short-term and long-term healing and has implications for all wound healing in medicine.
For the past 5 years in our office we have been treating patients with lasers after burn and trauma injuries within 3 months of injury. We have found that with early intervention fewer treatments are needed and that laser appears to have a powerful scar preventative effect. I am currently at the end of a 2-year clinical trial prospectively studying early intervention of fractional ablative CO2 laser with 830-nm LED phototherapy for acute burn injuries. Early laser intervention, especially in children, seems to melt away the scars, and fewer treatment sessions are needed.
LASER-ASSISTED DELIVERY OF DRUGS AND CELLS TO ENHANCE TREATMENT
Laser-assisted delivery (LAD) is an evolving method using full-field ablative devices. Fractional ablative lasers first emerged in 2007 and provide a novel way to create a conduit, or “channel,” through multi-thick layers in the skin, including the stratum corneum, epidermal, and dermal layers, in a rapid, predictable, and controlled pattern. These channels serve as access points for drug delivery or cell delivery, such as stem cells or skin cellular transplant, and allow for more effective transport of actives deeper into the skin.
LAD with ablative fractional laser pretreatment has already been reported and evaluated in clinical studies for a variety of dermatologic conditions. LAD of such actives as triamcinolone acetonide, 5-fluorouracil, poly- L-lactic acid, bimatoprost, PRP, vitamin CEF, biofilm, epidermal skin transplant, and stem cells for scars has been studied.
