Tattoo pigments are located in two layers: a thin layer close to the epidermis and a deeper layer towards the dermis. If only one side is treated, the remaining layer will still be visible.
This article summarizes the sequence in which the PicoWay Laser, Pico-Frectat, used at Yonsei Star Dermatology Sinchon, treats these two layers for tattoo removal.
A Method That Treats Both Shallow and Deep Layers
Tattoo removal can be performed using the PicoWay Laser. This method aims to remove both shallow and deep layers simultaneously.
The configuration is simple: a DOE fractional beam is irradiated first, followed by a second irradiation of zoom energy. The equipment configuration can be found in the R-Zero Pico-Frectat Tattoo Removal guide.

Micro-Holes Created in the Epidermis by the First Irradiation
The first step is PicoWay Resolve fractional beam irradiation. The fractional beam is irradiated onto the tattoo area to create micro-holes in the epidermis, first destroying the pigment in the upper layer.

Securing Space for Gas Bubbles to Escape in Advance
When pigments collide, gas bubbles are generated. The micro-holes created by the first irradiation become the space for these bubbles to escape.
Because a path for the bubbles to escape is opened first, it is reported that the risk of scarring and damage to surrounding skin is lower.
Methods for managing scars and blisters together are summarized in the Pinhole for Burn & Surgical Scar treatment guide.

Criteria for Choosing Wavelength in the Second Irradiation
PicoWay is equipped with multiple wavelengths, allowing the selection of a wavelength according to the tattoo color before irradiation.
- 532nm
- 730nm
- 785nm
- 1064nm
High-intensity energy breaks down pigment particles more finely, further removing pigment from the deeper, lower layer.

Two Stages Summarized in a Table
| Stage | Irradiation Method | Layer Treated | Role |
|---|---|---|---|
| 1st | PicoWay Resolve Fractional Beam | Epidermis and upper layer | Micro-hole formation and upper pigment removal |
| 2nd | Zoom energy with color-matched wavelength | Deeper lower layer | Further breakdown of pigment particles |
Since the two stages are performed consecutively, both shallow and deep layers can be treated in a single session. Individual differences in response and recovery may occur.

To Check if This Method is Right for Your Tattoo
The application method varies depending on the color, depth, and area. The overall treatment flow can be found in the Tattoo Removal Treatment Guide, and methods using other devices can be found in Nd:YAG Tattoo Removal.
