A laser is a beam of light that is concentrated with energy. This beam can selectively transmit its energy onto tissue in order to cure skin troubles of any kind, from eruptions to stretch marks. It can even be used in the treatment of eye defects such as nearsightedness, farsightedness or astigmatism. Lasers hold in themselves a material that creates and magnifies light. Two mirrors are used to reflect the light back and forth via this material. This gives rise to a beam that is packed and powerful, composed of one pure color or many different pure colors. These qualities, which distinguish a laser from a light bulb, make the former indispensable to medical applications.

The deployment of lasers in medicine is intricate, and plastic surgeons are trained to use lasers judiciously. They will be the best ones to decide if the use of laser is warranted in a particular case. Physicians use lasers to make cuts where necessary, eliminate tumors, close blood vessels and treat the skin for anything from acne to wrinkles, besides treating eye defects. The laser has the potential to change tissue without actually cutting into the skin. This makes major surgery unnecessary in the treatment of various conditions.

Laser surgery can do plenty in dermatology, ophthalmology and in the removal of tumors, for instance. The laser is similar to a scalpel, only composed of light, not steel. In dermatology, lasers help in the eradication of birthmarks, warts or other facial growths. Surgeons will use low intensity beams while working on facial tissue. This is done in order to preserve as much of the tissue as possible, which in turn, preserves natural beauty. Lasers are used in hair transplants, mainly to prepare the part where new hair will be placed.

After surgery, some inflammation is not uncommon. This can be treated with topical antibiotic creams. Avoiding exposure to direct sunlight also helps the process of recovery. The full impact of the operation may not be noticeable for over two months, especially where vascular defects are concerned. Any follow-up treatments will have to be scheduled after the initial healing process is complete.
