⭐ Yellow Laser (577 nm / 585 nm / 595 nm) 💛✨
🟡 What Is the Yellow Laser?
It’s a laser that emits yellow light at wavelengths like 577 nm, 585 nm, or 595 nm, strongly absorbed by oxyhemoglobin in blood vessels and melanin.
➡️ Meaning: SUPER effective for vascular problems, redness, rosacea, scars, and pigmentation. ❤️💛
🎯 How It Works (Mechanism) 🔬✨
👉 1. Selective Photothermolysis
🔥 Targets blood vessels (oxyhemoglobin) → heats them → makes them shrink or close.
🩸 Perfect for vascular lesions.
👉 2. Collagen Stimulation
💥 Heat triggers fibroblasts → produces new collagen → smoother, tighter skin.
👉 3. Melanin Reduction
💛 Light absorption reduces brown pigment gently (especially 577 nm).
