Laser Q-Switched technology has the ability to deliver deep impact to the skin, targeting the epidermis and dermis (the outermost layer and the layer between the epidermis and subcutaneous tissues of the skin).
Laser Q-Switched has 2 wavelengths: 562 nm and 1,064 nm. The 562 nm wavelength is suitable to target the epidermis while the 1,064 nm wavelength can target up to the dermis of the skin.
For hyper-pigmentation treatment, our doctors will use the 562 nm wavelength. The 1,064 nm wavelength is usually utilized for tattoo removal, birthmark removal...
When Laser Q-Switched is used for treating hyper-pigmentations, the laser beam will seek out the discoloration in the skin to gently shatter the unwanted pigment.
At ROHTO AOHAL CLINIC, the treatment interval for Laser Q-Switched is 4 - 5 weeks. This is the best interval to ensure safety and effectiveness of the treatment.
Other than treating hyper-pigmentations and evening out skin tone; Laser Q-Switched can also help resurfacing the skin, encouraging collagen & elastin production and smoothing out fine lines. Therefore, the skin will become smoother and more youthful-looking.
LASER HELIOS PRO – THE ADVANCED LASER TECHNOLOGY ELEVATES TREATING PIGMENTS TO NEW HEIGHTS
On November 11, 2024, ROHTO AOHAL CLINIC successfully organized the signing ceremony and technology transfer of Laser Helios Pro (Laser Helios III), a top-tier premium laser from South Korea, known as the 'king of melasma' and freckles removal.



Laser Helios Pro features Fractional Q-Switched Nd:YAG Laser technology, providing stable output energy for extended periods (over 30 minutes), with 40 times higher energy efficiency and a temperature reduction of 40%.
With two wavelengths of 1064 and 532, Laser Helios Pro offers 5 different laser treatment modes along with 4 different treatment heads of varying sizes that target different depths and skin pigmentation conditions while ensuring greater safety compared to other devices:
- 1G - Black Toning (Zoom tip 1064/532nm, spot size 1-7mm): Targets pigmentation between the epidermis and dermis.
- 2G - Blue-Toning (Standard tip, spot size 8mm): Addresses deeper pigmentation between epidermis and dermis than the 1G mode.
- 3G - Red Toning (Fractional 1064nm): Particularly effective for treating dermal pigmentation using the Fractional mode (patented and exclusively protected by Laser Optek). It minimizes pain and reduces risks during laser treatment.
- 4G - Green Toning (Fractional 532nm): Helps treat pigments located in the epidermis using Fractional mode, resulting in fewer side effects.

The Helios Pro Laser system with exclusive Dual Pulse (RTP) technology delivers exceptional results for:
- Tích hợp công nghệ Laser hiện đại và đỉnh cao nhất, cấu hình chùm tia đầu ra đồng nhất giúp giảm đáng kể tỷ lệ tăng sắc tố và giảm sắc tố.
- Có thể điều trị ở độ sâu thâm nhập sâu hơn của da.
- Hiệu quả lâm sàng cao hơn với ít thời gian nghỉ dưỡng và tác dụng phụ hơn.
- Skin rejuvenation
Key clinical advantages include:
- Integration of cutting-edge laser technology with uniform beam distribution, substantially reducing hyperpigmentation and hypopigmentation risks
- Enhanced penetration depth capabilities for more comprehensive treatment
- Superior clinical outcomes with reduced recovery time and minimal side effects
