Dual Yellow Laser is a skin-rejuvenation treatment that uses two wavelengths of laser light:
Yellow light (Copper Bromide 578 nm)
Green light (511 nm)
This technology is designed to improve and restore various skin concerns, such as uneven skin tone, redness, post-acne marks, and fine lines. It is a gentle procedure that typically does not require numbing cream and rarely causes scabbing afterward.

Ideal for individuals who want to:
Reduce red and dark acne marks
Improve uneven skin tone
Treat mild melasma and superficial pigmentation
Revitalize dull or tired-looking skin
Reduce overall skin dullness

How Dual Yellow Laser Works
Dual Yellow Laser emits two wavelengths, each targeting different skin concerns:
Yellow light (578 nm)
Helps reduce visible redness caused by skin inflammation (Post-Inflammatory Erythema). It may also support collagen production and enhance microcirculation beneath the skin.
Green light (511 nm)
Helps balance melanin distribution on the skin’s surface, making it suitable for treating pigmentation issues and uneven skin tone.
Key Benefits of Dual Yellow Laser

Brightens the skin for a more radiant appearance
Reduces mild pigmentation, melasma, and freckles
Promotes smoother, more refined skin texture
