Pigmented Lesion Laser

Pigmented lesions are areas of the skin that contain a higher concentration of melanin, resulting in darker coloration than the surrounding tissue. These lesions may be present at birth or develop over time due to sun exposure, aging, hormonal changes, or skin trauma. Common types of benign pigmented lesions include:

• Lentigines: Also known as liver spots or sunspots, these are flat, brown spots caused by cumulative sun exposure.
• Freckles: Small, light brown spots commonly found on the face, arms, and shoulders.
• Post-inflammatory hyperpigmentation: Dark patches that remain after acne, burns, or other skin injuries.
• Melasma: Although challenging to treat, some types of melasma may respond to laser treatment in conjunction with topical therapies.
• Café-au-lait spots: Light brown birthmarks that may fade with multiple laser treatments.
• Seborrheic keratoses: While typically removed via other methods, certain lasers can help reduce their pigment when necessary.

Pigmented lesion lasers use focused wavelengths of light that are absorbed by melanin. When the laser energy is absorbed, it causes the pigment to break into smaller particles. These fragments are then naturally eliminated by the body’s lymphatic system over the following days and weeks. Because the laser specifically targets pigment, it leaves the surrounding skin mostly unaffected, making this a safe and effective option for treating hyperpigmentation.

There are several types of lasers used for pigmented lesion treatment, including:

• Q-switched lasers (such as Nd:YAG or ruby lasers), which deliver high-intensity pulses in short bursts and are ideal for targeting deeper or more stubborn pigmentation
• Picosecond lasers, which use ultra-short pulses to break pigment into even finer particles, offering faster results and reduced risk of side effects
• Intense pulsed light (IPL), which is technically not a laser but uses broad-spectrum light to target superficial pigment, often used for lighter sun damage or diffuse redness
• The choice of laser depends on the type of lesion, skin tone, and the depth and color of the pigment

Laser treatment for pigmented lesions is typically performed in Dr. Neely’s office and does not require anesthesia. Before treatment, the skin is thoroughly cleansed, and protective eyewear is provided. During the procedure, the laser handpiece glides across the treatment area, delivering precise pulses of light. Most patients experience only a subtle, quick tingling, similar to a gentle snap against the skin, making the procedure very tolerable.

A typical session lasts anywhere from 15 to 45 minutes depending on the size and number of lesions. In many cases, more than one session is needed to achieve optimal results. The number of treatments varies based on the type of lesion, depth of pigmentation, and patient skin type.

Board-certified dermatologist Dr. Neely Khan will review your medical history and listen to your concerns and goals. She will evaluate the skin’s elasticity, degree of sun damage, muscle tone, and fat distribution to determine the most appropriate treatment or combination of treatments.
