How to Use Laser Machine for Hair Removal: A Step-by-Step Guide

Laser hair removal is a popular cosmetic procedure that uses concentrated light to target hair follicles, reducing hair growth permanently or semi-permanently. This guide provides professionals and users of beauty machines with factual and practical knowledge on operating laser hair removal devices safely and effectively.

What Types of Laser Machines Are Used for Hair Removal?

The most common types of laser technologies used for hair removal are Alexandrite (755 nm), Diode (800-810 nm), and Nd:YAG (1064 nm). Each wavelength targets melanin in hair follicles but is suited for different skin types and hair colors. Alexandrite is optimal for light to olive skin, Diode is versatile and suitable for most skin types, and Nd:YAG safely treats darker skin tones.

How to Prepare the Skin Before Laser Hair Removal?

Preparation is vital for effective and safe treatment. The skin should be shaved 24-48 hours before the procedure to ensure the laser targets follicles beneath the skin without burning surface hair. Avoid sun exposure or tanning for at least 2 weeks prior, and do not use chemical depilatories or waxing. Clean and dry skin free from lotions or makeup is necessary before treatment.

What Are the Recommended Settings for Laser Hair Removal Machines?

Settings vary according to skin type, hair color, treatment area, and device type. Energy fluence typically ranges from 10 to 40 J/cm². Pulse duration (milliseconds) and spot size must be adjusted for effective penetration while minimizing discomfort. Professional operators use Fitzpatrick skin typing and perform test spots to calibrate safely. Goodway machines provide adjustable and programmable control panels to customize treatment protocols.

How to Perform the Laser Hair Removal Procedure Safely?

Wear protective eyewear for both the operator and client. Keep the laser handpiece perpendicular to the skin and move systematically to cover the entire treatment area without overlap. Use cooling devices or gels if available to reduce discomfort and epidermal damage. Avoid treating over tattoos, moles, or active infections. Follow recommended session intervals, usually every 4 to 6 weeks, depending on hair growth cycles.

What Are the Post-Treatment Care Instructions?

After treatment, patients should avoid sun exposure for at least a week and use sunscreen (SPF 30 or higher). Mild redness and swelling are normal immediately post-treatment. Avoid hot baths, saunas, or harsh exfoliation for 24-48 hours. Regular sessions (typically 6-8) are required for optimal long-term results. Follow-up with a professional for assessment and management of any side effects.

By following these guidelines and leveraging Goodway's advanced laser hair removal equipment, beauty professionals can deliver safe, effective, and comfortable treatments, ensuring client satisfaction and optimal outcomes.
