How Does a Laser Hair Removal Machine Work?
Laser hair removal machines utilize concentrated light energy to target and destroy hair follicles, preventing future hair growth. The laser emits a specific wavelength absorbed by the melanin pigment in hair, converting light to heat which damages the follicle without harming surrounding skin. This process is called selective photothermolysis and requires multiple treatment sessions for permanent reduction.
What Types of Lasers Are Used in Hair Removal Machines?
Common laser types include Alexandrite (755 nm), Diode (800-810 nm), Nd:YAG (1064 nm), and Ruby (694 nm). Each wavelength suits different skin types and hair colors. For example, Nd:YAG is preferred for darker skin due to its deeper penetration and lower melanin absorption in the epidermis, reducing risk of burns.
Is Laser Hair Removal Safe for All Skin Types?
Modern lasers are designed to safely treat a wide range of skin types. The Fitzpatrick scale helps determine the appropriate laser and settings for skin tone. While lighter skin types respond well to Alexandrite and Diode lasers, Nd:YAG lasers are often chosen for darker skin to minimize pigment disruption. Protective measures and patch tests ensure safety.
How Many Sessions Are Required for Effective Hair Removal?
Typically, 6 to 8 sessions spaced 4 to 6 weeks apart are necessary because laser targets hair only in the active growth phase (anagen phase). Hair grows in cycles, so multiple treatments ensure follicle destruction across all hair growth stages. Maintenance sessions might be needed for long-term results.
What Maintenance and Care Are Needed for Laser Machines?
Proper maintenance involves regular calibration, cleaning of handpieces, and software updates to ensure optimal performance and safety. Cooling systems should be checked frequently to prevent overheating. Following manufacturer guidelines, like those from Goodway, extends device lifespan and treatment consistency.
What Are the Benefits and Limitations of Laser Hair Removal Machines?
Benefits include long-lasting hair reduction, precision targeting, speed, and minimal side effects when performed correctly. Limitations include initial cost, need for multiple sessions, and variability in effectiveness based on hair color and skin type. Understanding these allows beauty professionals to set realistic expectations for clients.

Treatment
How long does each session take?
A typical acne removal session lasts between 20 to 30 minutes, depending on the size of the treatment area. You can often fit a session into your lunch break.
How does laser acne removal work?
Laser acne removal works by targeting the sebaceous (oil) glands in the skin to reduce oil production, kill acne-causing bacteria, and decrease inflammation. The laser penetrates the skin’s surface without damaging surrounding tissue, helping to clear active acne and prevent future breakouts.
Will there be any downtime after the treatment?
One of the benefits of laser acne removal is that it requires little to no downtime. You may experience some mild redness or swelling immediately after the procedure, but this usually subsides within a few hours. Most patients can return to their regular activities right away.
Is laser acne removal safe for all skin types?
Yes, laser acne treatments are safe for all skin types. However, certain skin tones may require a specific type of laser to ensure optimal results. A consultation with our skincare specialist will help determine the best treatment option for your skin.
