From their conception in the early 1900s to their first creations in the 1960s, lasers have been a topic of great interest in the fields of science and medicine. What was originally a mere concept by the late Albert Einstein is now breakthrough technology in cosmetic procedures and medical practices alike.

For those in either of the aforementioned fields, cosmetic lasers can be beneficial for the treatment, beautification, and prevention of impurities and serious conditions. Their usage covers vast ranges of procedures and treatments, specifically in these five areas.

Spa treatments and the healing of skin conditions

Several spas offer laser treatments at the forefront of their services. The reason behind this lies in the laser’s ability to remove wrinkles, tighten the skin, even reverse signs of aging and acne scars. There are a variety of laser options to consider when performing these treatments.

Websites such as cosmeticwarehouse.com sell used lasers at discounted prices, thus making them more affordable for business owners to purchase for their centers. Each laser is designed with specific capabilities and can be used for various procedures accordingly:

Fractional lasers: These particular lasers are used to treat signs of aging such as dark spots. Instead of an individualized laser, the light is dispersed into thousands of micro-sized beams to aim at the specific blemish being treated.

Pulsed-dye lasers: This laser is used to infuse heat into the skin and remove pigmentation impurities. Procedures with the pulsed-dye lasers include the treatment of rosacea and hyperpigmentation.

CO2 and erbium lasers: These two lasers are most commonly used for removing wrinkles, fine lines, acne scars, and other impurities lying deep in the skin. While CO2 lasers are ablative (meaning the epidermal layer is removed during treatment), erbium lasers can be either ablative or non-ablative depending upon the procedure.

Cancer treatment

CO2 lasers are often used for more than just reversing the signs of aging. In the field of medicine, this particular laser can be used in the treatment of certain cancers.

With the ability to cut surface layers of the skin without damaging underlying tissue, CO2 lasers can be used to remove skin cancer in most patients. The laser itself leaves behind little to no scarring.

Furthermore, laser treatments are outpatient procedures which means less hassle for the patient and a recovery time that is cut substantially in comparison to that of inpatient treatments and procedures. For some, laser treatments are done in one session, while others may need repeated treatments for the prevention of new issues.

Tattoo and hair removal

There are a variety of reasons why a person would choose to remove a particular tattoo. Whether that reason is the sudden change in beauty trends or the regret of a permanent name, cosmetic lasers can remove most if not all of the original design using rapid heat.

This heat is targeted at the ink particles originally injected into the skin by the tattoo artist. When the heat is injected into the skin, it breaks the ink into smaller pieces that can then be absorbed by the white blood cells to be removed through the liver. This process can take multiple (and often painful) sessions depending upon the complexity of design and placement.

Before setting an official appointment, professionals recommend scheduling a consultation to be evaluated for tattoo removal. In order to ensure that the skin is properly cared for, consider having the procedure done at a dermatologist over a tattoo parlor or spa center. Dermatologists have a specialized knowledge of the skin and its healing processes.

Similarly, cosmetic lasers can be used to remove unwanted hair. This process is done by absorbing the pigment in the hair and damaging the hair follicles that produce them. This damage can then delay the growth of new hairs or inhibit future growth altogether. These procedures vary based on location, color, and texture of hair, and should be done by a professional.

While hair is rarely removed permanently, the new hair growth is often lighter, less coarse, and finer. Follow-up treatments will be necessary but spaced in longer durations over time. Overall, choosing laser hair removal is preferred by many over traditional methods such as shaving, waxing, or the use of hair removal creams.
