How the New Phototherapy Skin Treatments Work

The word laser stands for Lightwave Amplification by Stimulated Emission of Radiation. A laser beam is a very strong (amplified) light beam (radiation) that is emitted (emission) from a tube which is designed to produce one specific color or wavelength of light. A complex electric method is used to stimulate (stimulated) the lighting into a strong amplified state. Medical and surgical lasers are designed to produce or create certain colors that are highly and specifically absorbed by different cells of the body. This technique is known as phototherapy or light treatment. When a laser beam strikes a tissue that is the appropriate color for that specific laser beam, the laser energy heats and destroys the tissue.

For instance, a laser beam that has a laser wavelength of 650nm (nm is the device that defines a particular color of light from the visible spectrum) is preferentially consumed by the color brown. In case this 650nm laser beam strikes a brown spot on your skin, the brown spot will be heated and vaporized.

Before lasers and phototherapy, nonspecific warmth, such as electrocautery or surgery with a scalpel was used to remove a brownish skin lesion such as a sunspot or age spot. The problem with this old technique was that the damage has been non-specific for the color brown and ruined all elements of this brown spot and the normal skin around the brown spot. The result was a much bigger skin harm than needed just to eliminate the brown place. A larger wound was created and a scar was the result. Visit Canyon Laser Skin Care here.

Considering that a light beam used in phototherapy can specifically eliminate only the brown place, the surrounding skin is not injured and a brown spot can be removed and the skin is left with no scar.

This specificity of the light beam for a particular colored target is called Target Specific Photothermolysis. Photo stands for mild. Thermo stands for warmth. Lysis stands for rupture, removal or vaporization of the goal. The light hits a specifically colored target, heats the goal (a brown place ) and vaporizes the target-brown place.

There are dozens and dozens of different wavelengths which can be tuned to vaporize quite specifically colored biologic targets on the human body. The color of hair, blood vessels, tattoos, veins, arteries, pigment in brownish spots and other colors can every be specifically targeted very best by one specific wavelength. The trick is to create the specific wavelength that’s needed for the application you would like. Some wavelengths used in cosmetic surgery are:

  • 532nm-Absorbed by red-purple-used to vaporize blood vessels and spider veins
  • 755nm-Absorbed by brown-black and utilized for hair removal and tattoo removal
  • 1064nm-Absorbed by purple-black and utilized for hair removal and closing of large veins
  • 10,000nm-CO2 absorbed by water in the skin cells ruptures the skin cell, used for incisions and also to vaporize skin growths
  • 1440nm and 1540nm-Erbium consumed by water and used to coagulate deep hydration in the skin to stimulate new collagen and plump skin wrinkles and acne scars
  • 2940nm-Erbium consumed by water purification cells used to resurface the skin and remove wrinkles
  • 924nm- The 924nm is absorbed by the color yellow and can be used to melt down fat through liposuction

What’s laser plastic surgery done?

All of the phototherapy techniques operate by generating heat. This heat can be used to regenerate tissue, coagulate tissue, meltdown tissue and incise or cut tissue. The most Frequent use of these four approaches are:

  • Vaporize Tissue-Removal of warts, skin cancers, sun damage, brown spots, wrinkles, and bumps on the skin and other skin growths known as lesions.
  • Coagulate Tissue-Coagulate means to fool a liquid into a solid; the traditional illustration is the coagulation of blood to form a blood clot. This technique may be used to coagulate blood in a vein or artery as well as the injury causes the boat to shut and thus remove the artery or vein. Heat may also be passed through the skin to coagulate or injure collagen deep in the epidermis. This process is utilized to stimulate the skin to produce new collagen which can plump wrinkles or enhance acne scars.
  • Melt Tissue-The 924nm wavelength used in liposuction involves using heat to melt and liquefy fat beneath the skin. Some fat is also coagulated within this process.
  • Incise or Cut Tissue-This kind of incision is most often used to do eyelid operation called blepharoplasty, an operation to eliminate eye hoods and bags under the eyes. Thicker skin is not routinely incised with this technique because heat buildup is higher in thick skin and can cause scarring. On the other hand, the eyelid skin is a perfect application for this technique. The advantage is that blood vessels are sealed throughout the incision hence there is less bleeding and less bruising after the operation.

What Is IPL-Intense Pulsed mild or Photo-facial another Phototherapy?

Intense pulsed light, also called IPL or Photo facial is also a kind of phototherapy or light treatment used in cosmetic surgery and dermatology. Intense pulsed light (IPL) utilizes a flash of bright visible light, like a very strong camera to heat tissues and vaporize or coagulate the tissue. The specific colors or wavelengths necessary to treat different colored tissues is released by placing a filter in the front of the light flash that only transmits the correct wavelength chosen for the program.

Depending on the filter used, ideal wavelengths of light for hair removal, elimination of blood vessels and brown spots and removal of dark circles under the eyes caused by broken blood vessels are all readily available.

IPL is not as strong and generally is not as painful when used on the skin-often no anesthetic is required. Additionally, skin burns or injury are less regular using Intense Pulsed Light.

Intense pulsed light or Photo-facial is a great process to treat large skin areas. Photo-facial treatments may be utilized to eliminate brown spots, small blood vessels and sunlight damage in the face, chest, and hands. Because the Intense Pulsed light therapy head is bigger, the results of remedies are more uniform with no white marks out of overtreatment with more concentrated devices.

Intensely pulsed light treatments may also be performed for hair removal. Again, larger regions are easily treated faster and uniformly. Intense pulsed light is particularly helpful for large areas such as the trunk, legs, and chest.
