Laser Treatment of Pigmented Lesion

Pigmented Lesion (Melasma, Solar or Senile Lentigo, Actinic Keratosis and Stains)

Pigmented lesions are remarkably common and the overwhelming majority are benign. It is widely recognized in the medical community that Q-Switched lasers are the ideal tools for effectively removing benign pigmented lesions. Multi-wavelength, Q-Switched laser systems with frequency-doubled KTP are uniquely able to produce very short pulses of intense light that are selectively absorbed by treatment-specific pigments in a lesion.

Four Wavelengths for the Widest Range of Lesions

Our StarWalker laser system is the perfect tool for treating a wide range of pigmented lesions, enabling treatments for everything from nevi (moles) and vascular lesions to ephelides, sunspots and melasma. Superficial lesions can be treated most effectively with the 532 nm wavelength, while the 1064 nm wavelength can be used to target deeper lesions.

Procedure Time:

10 – 20 Min



Recovery Time

4 to 24 hours

Down Time

1 – 3 Days

Final Results

3 weeks



Sessions Recommended:

1 or 2 Session, until Pigmented Lesion is gone.

Safe, Effective and Minimally Invasive Treatments

The StarWalker is especially effective for difficult-to-treat conditions due to the selectivity of Q-switched light, enabling it to break apart pigments only and not cells. This means that pigment destruction can take place without ablating the skin – a unique feature that also allows other treatment possibilities, such as the safe and effective removal of complex, multi-colored tattoos.

In addition to Q-Switched lasers, Er:YAG lasers can also be used for the ablation of keratoses, moles, and other pigmented lesions, enabling the removal of the epidermis and superficial dermis in a controlled and relatively bloodless manner. Clinical studies have shown that Er:YAG lasers are very effective for the treatment of keratoses, with the clinical and histological improvement of up to 93% after just one treatment.

Treatments for the removal of pigmented lesions can be best performed with the following Fotona laser systems:

  • Fotona’s StarWalker system is a high-performance Q-switched laser on the market. With four wavelengths in one system, the StarWalker provides all the tools you’ll need for effective removal of most types of pigmented and vascular lesions as well as complex, multi-colored tattoos.
  • The SP Line of multi-application laser systems from Fotona (SP Dynamis & SP Spectro) provides a single, uniquely capable aesthetic solution that combines the power of the industry’s highest performance Er:YAG, Nd:YAG and QCW* Nd:YAG lasers, ideal for treating keratoses, moles, and other pigmented lesions plus a wide range of additional treatments in aesthetics, dermatology, and surgery.

Superior Performance

The StarWalker’s state-of-the-art, high-energy, single-pulse technology is vastly more efficient at removing pigments than multiple-pulse lasers that generate equivalently high energies. The StarWalker’s high-energy Q-switched technology allows larger spot sizes to remain effective by avoiding the scattering effect of laser light in skin tissue.

High-energy, single pulses are not affected by the optical shielding phenomenon arising from pigment destruction, which means that more and deeper lying pigments can be targeted and removed, thus maximizing laser treatment efficacy and efficiency in a single session. The use of larger spot sizes also requires less fluence to be effective.
