1470 nm Laser: The Representative Wavelength of Non-Ablative Water-Targeted Heating
What Is the 1470 nm Laser?
1470 nm sits at a secondary peak of water’s near-infrared absorption curve — a “water-targeted” wavelength: far less ablative than 2940/10600 nm and not melanin-driven like 1064 nm. It deposits energy in the superficial-to-mid dermis while the epidermis stays intact, triggering collagen remodeling through coagulative injury — classic non-ablative logic.
Fractional “Glass Skin” Treatments
Delivered fractionally (often marketed as “glass skin” or glow treatments), 1470 nm creates hundreds-of-microns-wide micro-heating zones with only brief erythema and essentially no downtime, suiting fast-paced patients. Cumulative improvement in texture, fine lines and pore appearance appears over a course of sessions.
Other Applications
- Endovenous laser ablation (EVLA) — 1470 nm is widely used in vascular surgery, reflecting its combined water/hemoglobin absorption.
- A component of facial rejuvenation maintenance, combined with IPL and RF platforms.
Parameters and Non-Ablative Realities
- Gentle per session; standard courses are 4-6 sessions at 3-4 week intervals.
- No real crusting phase; normal social activity the same day (sun protection still required).
- Better tolerance in darker skin than short-wavelength IPL.
LEIJEX’s 1470 nm non-ablative fractional platform is built on this wavelength.
FAQ
1470 nm vs photorejuvenation — how to choose?
For refined texture with no downtime, choose 1470 fractional; for pigment and vascular targets, IPL comes first. The two are often alternated within one treatment plan.
How many non-ablative sessions until results?
Most people notice texture changes after 2-3 sessions in a 4-6 session course; collagen remodeling continues to show for months after completion.
