Functions

Hair removal

Dermatology laser machines can remove hair through the process of photothermolysis, which targets hair follicles to inhibit and delay future hair growth. It is an effective and long-term solution for unsightly body and facial hair.
Tattoo removal

Lasers can remove tattoos by breaking up the pigment colour in the tattoo with a high-intensity light beam. The black tattoos are the easiest to remove because they absorb all laser wavelengths. Laser tattoo removal typically requires multiple treatments to see effective results.
Wrinkles, fine lines, and skin laxity removal

Laser is used to remove wrinkles and fine lines by resurfacing the skin. It also helps treat all types of scars, including surgical scars, acne scars, and scars from injury. The laser promotes new skin cells to grow, which helps tighten and rejuvenate the skin, giving it a youthful appearance.
Skin pigmentation

Laser machines can remove skin lesions like moles, freckles, age spots, birthmarks, and liver spots. It can also treat vascular lesions like hemangiomas, port wine stains, and telangiectasias.
Skin cancer treatment

Laser machines can treat precancerous lesions like actinic keratosis. Some doctors use lasers to remove or destroy cancerous tissue.

Q&A

Q1: What is the difference between Nd YAG and diode laser machines?

A1: Both Nd YAG and diode lasers are used in dermatology, but they differ in their technical parameters and applications. The Nd YAG laser emits light at a longer wavelength, penetrating deeper into the skin. This makes it more effective for treating deeper issues like scar tissue or wrinkles. On the other hand, diode lasers have shorter wavelengths, allowing them to target more superficial skin concerns like acne or vascular lesions. Diode lasers are often used in hair removal treatments as well.

Q2: How do CO2 and Erbium lasers compare in terms of recovery time?

A2: The CO2 laser typically requires a longer recovery period because it removes more layers of skin at once. This can result in more redness, swelling, and crusting that take time to heal. The Erbium laser is less invasive, treating only the top layer of skin with minimal damage. As a result, patients can recover faster and see results sooner.

Q3: What is the average lifespan of a laser machine used in dermatology?

A3: The average lifespan of a laser machine can range from 5 to 15 years, depending on the type, level of usage, treatment applications, and regular maintenance. For example, CO2 and Nd YAG machines tend to last longer because of their more durable construction.

Q4: Are there any laser machines that work better for dark skin tones?

A4: Certain lasers are safer and more effective on darker skin types. Diode lasers have longer wavelengths, which penetrate deeper without stimulating melanin in the surface layer. This lessens the risk of hyperpigmentation in untreated areas. Ruby lasers also avoid melanin stimulation while precisely targeting hair follicles for effective laser hair removal.
