Lasers are medical devices that generate high-energy, concentrated beams of intense, “single-colored” light and heat that have been discovered to communicate selectively, in very helpful ways, with different tissues within the skin and body through continuing studies and comprehensive clinical experience.
The quantity and distribution of laser light energy are supplied more accurately. This can, therefore, have a benefit over the mechanical implementation of a scalpel or topical chemicals to successfully treat many aesthetic and medical circumstances.
Lasers are doing three skin stuff. Reduction of hair, rejuvenation of skin and treatment of skin lesions.
1. Laser hair removal
This is a cosmetic operation that utilizes a strong diode-like laser to remove unwanted hair. This light source heats up and destroys hair follicles in the skin that interferes with hair development. The face, shoulders, arms, underarms and bikini line are common places to be treated.
Women with hirsutism (excessive hair development) may find it useful. It is most efficient for females with pale skin and dark hair. Up to six sessions spaced four to six weeks apart, may be suggested. Laser hair removal findings may not be permanent.
They generally last from weeks to months, and to attain and retain the required impact, periodic sessions may be necessary. There is no assurance that all hair will be evident. Take time to find a reputable practitioner who is properly qualified and practices in a clean, safe and appropriate environment.
The day before your appointment, you will need to shave the skin region. During the procedure, you will wear specially designed goggles on the day to protect your eyes. There is no need for local anesthetics.
The doctor usually applies a cool gel or cooling air spray to the skin region. Then press on a handheld device on your skin and activate the laser. This may feel like an elastic band snapping on your skin. Each session can take from 15 minutes up to an hour.
The number of sessions needed depending on the region to be lasered and the system to be used.
The region may be red for up to 24 hours with an elevated rash. It may be helpful to hold an ice pack on the skin. After laser hair removal, your skin will become more susceptible to the sun. For at least one week after therapy, avoid sun exposure and tanning beds and use sunscreen.
2. Laser Skin Resurfacing
Laser resurfacing utilizes a specially designed thermal energy beam such as carbon dioxide laser that works deep into your skin’s layers. These heat laser beams exactly aim and vaporize damaged skin, unlike peels or abrasive skin exfoliation.
The body operates to generate fresh, tighter skin with lower pores and fewer wrinkles and blemishes by causing injury to the ancient skin. Resurfacing of the skin removes the epidermis and penetrates the papillary dermis, which reacts by generating fresh collagen. This enables the skin to be healed and regenerated.
Usually, this is performed to enhance skin wrinkles or acne scars or other imperfections. Time of treatment relies on the situation and size of the treatment region. It can take between 20-30 minutes for small regions such as an upper lip and chin.
3. Laser Removal of Birthmarks, tattoos, and Skin Lesions
Birthmarks of port-wine stain react extremely well to laser therapy. The laser reduces the abnormal blood vessels that cause these marks in size. This results in the region being handled being lightened.
Grows in the skin, facial “spider veins,” warts, and tattoos that react to laser surgery. Most circumstances require more than one therapy with laser, but some react to one therapy. A unique laser may also remove the tattoos.
Dr. Anup Dhir, senior cosmetic surgeon, Apollo Hospital says, “New technology has made the use of lasers secure. But going to a qualified cosmetic surgeon who has laser expertise for these processes is crucial.
Lasers can be dangerous if they are not correctly applied. The plastic surgeon often utilizes as little as possible laser intensity. A lot of treatments are required for low intensity. The low intensity, however, also maintains the good tissue as much as possible.
This generates a pleasing aesthetic outcome. Many of these laser surgeries are performed in hospitals or offices as ambulatory treatments”.
Your surgeon will clarify the laser of selection and what can be achieved after your surgeon has stated that a laser can be useful in the surgery. The laser has its constraints, as with all surgery. The findings are frequently very nice. The best judgment for the specific operation will be given to you by your surgeon.
Some surgeons may use local anesthetics before surgery to soothe the treated region. Surgery can sometimes be performed in the office of the surgeon; other times the surgery is performed in a clinic or hospital outpatient facilities. Your surgeon will decide which technique is suitable, dictated by the nature of the operation.
Because safety is a significant element of laser use, prior to surgery, your surgeon will define safety precautions. You are likely to experience some swelling and redness of the skin for several days after the surgery.
During the healing process, antibiotic ointments can be used. It is essential for the patient to follow all the post–the surgeon’s surgical instructions, especially when using sunblock and avoiding exposure to the sun.
For a month or two, particularly with vascular deformities, the complete effect of the laser may not be evident. Additional therapy sessions are not planned until the healing process is complete for specific therapy.
