What Is PiQo4?

PiQo4 is a breakthrough laser system that combines four wavelengths and both nano and picosecond pulse durations to target pigment in the skin with remarkable speed and accuracy. This dual-pulse capability allows it to shatter pigment particles of all sizes and depths—making it effective for both natural discoloration and the most stubborn tattoo inks. Unlike traditional lasers that may require multiple treatments with limited outcomes, PiQo4’s high energy and large spot size reduce the number of sessions needed, minimize downtime, and deliver more consistent, even-toned results.

What Can PiQo4 Treat?

PiQo4 is an exceptional choice for treating:

Sunspots and age spots
Melasma and hyperpigmentation
Freckles and café-au-lait birthmarks
Lentigines and pigmented lesions
Vascular lesions and redness
Tattoo removal (including stubborn blue, green, and black inks)
Uneven skin tone or texture

Your PiQo4 Treatment Experience

Before Your Session

No extensive preparation is required. However, our team will evaluate your skin concerns and discuss the number of sessions likely needed for optimal results.

During Treatment

Most patients describe PiQo4 treatments as comfortable, with a warming or snapping sensation in the treatment area. In most cases, no numbing is necessary, but a topical anesthetic can be applied upon request.

Sessions typically take 20–30 minutes, depending on the size and complexity of the area being treated.

After Treatment

Mild redness, swelling, or a sunburn-like warmth may appear but usually subsides within a few hours. There is no required downtime, so you may resume your daily routine the same day.

We recommend avoiding direct sun exposure and using sunscreen to protect the treated area as your skin heals.

Am I a Candidate for PiQo4 in San Mateo?

You may be a great candidate if you are:

In good overall health
Seeking treatment for discoloration, melasma, or tattoo removal
Looking to improve skin texture and tone
Not currently pregnant or breastfeeding
Not on medications that cause photosensitivity
Not prone to keloids or severe scarring

A personal consultation at Cheng Plastic Surgery will help us determine if PiQo4 is the safest and most effective treatment for your unique skin goals.

When Will I See Results?

Results typically develop gradually as the body clears broken-down pigment through its lymphatic system. Most patients see visible improvements after just 1–2 sessions, with continued enhancement over time.

For pigmentation:

3–5 sessions may be recommended depending on the depth and type of discoloration.

For tattoos:

4–8 sessions are typical, depending on ink color, size, and location.
