How is the LEFIS hair removal device useful?

Stay In The Know

Expert advice. Very good deals. The absolute best (and worst) things we've tested lately.

Unwanted body hair has always been one of the most persistent beauty concerns for women and men alike. While shaving and waxing offer temporary relief, they come with irritation, regrowth, and endless upkeep. That’s why advanced technologies like 808 nm diode laser hair removal have become the global gold standard for safe, effective, and long-lasting results.

The Lefis hair removal device combines medical-grade precision with user comfort, delivering salon-quality performance in every session. Let’s explore how this professional system works, what makes it superior, and why it has become a trusted choice among beauty clinics and aestheticians worldwide.

Technology Behind the Lefis Hair Removal Device

808 nm Diode Laser — The Gold Standard

At the core of the Lefis hair removal device is 808 nm diode laser technology, based on the principle of selective photothermolysis. The laser emits a concentrated beam of light that specifically targets melanin pigment within hair follicles.

When the pigment absorbs the laser energy, it converts to heat, raising the follicle’s temperature to a level that disables future hair growth—without harming the surrounding skin.

This wavelength is clinically proven to provide the perfect balance between penetration depth and absorption, making it suitable for all skin tones and hair types.

Key Technical Advantages

Precision Targeting: Focuses only on the follicle pigment without damaging nearby tissue.
Speed and Coverage: Large spot sizes (up to 12 × 35 mm) treat more skin per pulse for faster sessions.
Stable Energy Delivery: Ensures uniform fluence (5–178 J/cm²) for consistent results.
Smart Cooling System: Uses water, air, and sapphire semiconductor cooling to protect the epidermis and reduce pain.
Multi-Wavelength Options: Some models combine 755 nm, 808 nm, and 1064 nm for total body versatility—from fine facial hair to coarse leg hair.

How Does the Lefis Hair Removal Device Work?

Step 1: Melanin Absorption

The laser beam passes safely through the skin to reach the root of the hair follicle, where melanin absorbs light energy.

Step 2: Heat Conversion

The absorbed light transforms into heat, raising the temperature inside the follicle to around 70°C.

Step 3: Follicle Disabling

This heat damages the bulb and bulge region—key structures responsible for hair regeneration—without affecting surrounding tissues.

Step 4: Natural Hair Shedding

Within 7–14 days, treated hair sheds naturally. Over multiple sessions, fewer and finer hairs grow back, leading to permanent reduction.

Because only hairs in the active anagen phase respond to laser treatment, a series of 6–8 sessions spaced 4–6 weeks apart is typically required for optimal results.

Main Features of the Lefis Hair Removal Device

Certifications	FDA, CE, ISO13485, ROHS certified

This powerful configuration allows safe and effective treatment across all body areas—face, arms, underarms, legs, bikini, and back—while maintaining maximum comfort.

Why Choose 808 nm Diode Technology?

Deep Penetration

The 808 nm wavelength reaches the mid-dermal layer (2–3 mm depth), effectively heating the entire follicle while leaving the epidermis untouched.

Safe for All Skin Types

With built-in cooling and pulse modulation, it’s safe for Fitzpatrick skin types I–VI, including darker tones.

Pain-Free Experience

The sapphire contact tip cools skin to 0–5°C during treatment, preventing burns and providing an almost painless experience.

Fast Treatment Speeds

Thanks to its large spot size and 10 Hz frequency, full leg treatment can take as little as 20–30 minutes—half the time of older laser systems.

Proven Efficacy

Clinical research shows up to 90% long-term hair reduction after a complete treatment course.

Comparison with Other Hair Removal Methods

Method	Duration	Pain Level	Effectiveness	Cost Efficiency
Shaving	1–3 days	Mild	Temporary	Low but recurring
Waxing	3–6 weeks	Moderate	Temporary	Moderate
IPL Devices	6–12 months	Mild	Semi-permanent	Moderate
808 nm Diode Laser (Lefis)	12–18 months+	Minimal	Permanent Reduction	High ROI

With precise wavelength control, higher power output, and consistent pulse energy, diode laser systems outperform IPL or waxing in both safety and longevity.
