Skin is the major and the most visible part of our body. Serving many purposes, starting from sense to protection, it endures all the environmental chaos, the use of harsh products and many other external and internal nuisances. Any problem, in any part of the body, will affect the skin for sure. Age is another aspect that affects the skin.

Laser skin resurfacing eliminates skin layer by layer with precision. The new skin cells that generate during healing give the skin a tighter, younger looking surface. The procedure can be done individually or with other cosmetic surgeries on the face.

 

Types of Lasers:

There are numerous types of lasers used in skin laser therapy. The wavelength peaks of the laser light, pulse intervals and how the target skin tissue absorbs this, determine the clinical applications of the laser types. The broad two categories are:

 

  1. Ablative Lasers:

In this technique, an intense wavelength of light is ejected into the skin, which removes the external layers of aged or sun damaged skin. Laser stimulates the underlying skin, resulting in collagen formation and an improvement in wrinkles. After laser resurfacing, an ointment and dressing is applied to the skin. Once the skin restores after the treatment, new skin forms that is smoother and tighter. Ablative Lasers are of two types:

 

  • Carbon Dioxide Laser (Co2):

It was first familiarized during the late ’60s and is still being used for skin rejuvenation. It is not suitable for darker skin tones. It is used in situations of skin cancer, birthmarks, other scarring warts, moles, skin tags, saggy skin (encourages collagen production for skin tightening) and sun damage.

 

  • Erbium Yttrium-Aluminium-Garnet:

It helps to get rid of surface-level and moderately deep lines and wrinkles on the face, hands, neck or chest with negligible burning of surrounding tissues. With lesser side effects, it heals quicker than CO2 Laser treatment.

 

  1. Non-Ablative Laser:

Contrasting to ablative technologies that heat and remove the top skin tissue, non-ablative (or non-wounding) laser work underneath the surface skin layer. It arouses collagen growth and tightens the underlying skin to improve the skin tone. It also eliminates fine lines and mild to moderate skin damage.

Non-Ablative Laser-based treatments are of the following sorts:

 

  • Pulsed Dye Laser:

It treats the skin by directing the blood vessels directly to shrink them, making the skin less red. It requires around 3 to 5 sessions of treatment. Results are permanent. The time taken for healing is just few hours, during which the pinkness and the redness subsides.

 

  • Nd: Yag Laser:

Neodymium-doped Yttrium Aluminium Garnet is a crystal that is implemented as a laser medium for solid-state lasers. These release a wavelength of high energy light, which when focused on a certain skin condition, generates heat and destroys the diseased cells.

 

  • Alexandrite Laser:

This laser emits wavelength of high energy light that is transformed to heat energy. This damages the precise target area. Alexandrite lasers cause very accurate tissue destruction of the lesion and leave tissue in the surrounding area undamaged.

 

With advancing technology, there are innovative types of lasers being introduced for various skin problems and skin types. And with so many diverse types of laser skin treatments available, it is tough to zero in on the one that will work for you. So, it is very important to consult a Laser and Skin Care Specialist to finalize the treatment plan, tailor-made for you!
