Indications

What LaseMD Ultra™ Treats

A versatile fractional thulium laser cleared for a broad range of skin concerns — from surface texture and tone to deeper pigmentation and laxity.

Pigmentation & Sun Damage

Fades sunspots, age spots, and uneven pigmentation caused by UV exposure and aging with targeted thulium energy.

Skin Texture & Tone

Smooths rough, uneven skin surface by resurfacing the epidermis and stimulating healthy collagen production below.

Fine Lines & Wrinkles

Reduces superficial lines around the eyes, mouth, and forehead by triggering the skin’s natural regenerative response.

Acne Scarring

Improves the appearance of shallow acne scars by promoting dermal remodeling and smoothing the skin’s surface.

Drug Delivery Enhancement

Creates micro-channels that allow topical serums to penetrate 10–20× deeper, amplifying active ingredient absorption.

Overall Skin Rejuvenation

A full-face reset that brightens dullness, tightens pores, and restores a youthful, luminous baseline.

The Process

How LaseMD Ultra™ Works

A fractional thulium laser creates thousands of controlled micro-columns in the skin, triggering the body’s own repair cascade while leaving surrounding tissue intact for rapid recovery.

Micro-Column Delivery

The 1927nm thulium laser creates microscopic treatment zones across the target area, precisely controlled for depth and density.

Cellular Renewal

Controlled thermal energy triggers the skin’s healing response — shedding damaged cells and producing fresh, healthy tissue from within.

Serum Amplification

Micro-channels created during treatment allow specialized ampoules (CosmelanMD, RetinolMD, VitC) to penetrate 10–20× deeper.

The PH Med Difference

Physician-Performed. Every Time.

At PH Med, every LaseMD Ultra treatment is performed directly by Dr. Pauline Bui — not delegated to a technician. This ensures precise energy delivery, customized depth settings for your skin type, and outcomes that match the standard of care you’d expect from a physician-led practice.

Our image-guided approach means your treatment parameters are calibrated to your skin’s specific needs — not a one-size-fits-all protocol.

FAQ

Common Questions

How many sessions do I need?

Most patients see visible improvement after 1–2 sessions, but a series of 3–6 treatments spaced 2–4 weeks apart is recommended for optimal results depending on your skin concern.

Does it hurt?

Most patients describe it as a warm, tingling sensation. A topical numbing cream is applied before treatment to maximize comfort. LaseMD Ultra is one of the most tolerable laser treatments available.

What’s the downtime?

Little to no downtime. You may experience mild redness for 1–3 days and light micro-peeling on days 2–4. Most patients return to normal activities the same day.

Can LaseMD Ultra be combined with other treatments?

Yes. LaseMD Ultra pairs well with XERF for a comprehensive rejuvenation protocol — addressing both surface texture and deeper structural concerns in a single visit plan.

Is it safe for all skin types?

Yes. The 1927nm thulium wavelength is safe for all Fitzpatrick skin types (I–VI), including darker skin tones that may not be candidates for other laser treatments.
