PH Regenerative Systems

The Science of Stacking Treatments

Some results can’t be achieved with a single treatment. PH Regenerative Systems are curated combinations — sequenced by Dr. Bui to work synergistically, so each treatment amplifies the next.

The Logic of Synergy

Treatment A + Treatment B = More

When treatments are sequenced correctly, each one enhances what came before it.

The Science

Why Stacking Works

The skin responds to treatment at multiple levels simultaneously — surface, mid-dermis, and deep tissue. Most single treatments address one level well. A well-designed system addresses all three in the right sequence.

Three Layers

The Regenerative Framework

Each layer builds on the last for compounding results.

Surface Renewal

Treatments like LaseMD Ultra™ and microneedling work at the epidermal and upper dermal level — improving texture, tone, pigment, and triggering initial collagen signals.

Deep Regeneration

XERF™ radiofrequency and energy-based treatments reach the deeper dermis and subcutaneous tissue — remodeling collagen structure, tightening, and building a regenerative foundation.

Infusion & Amplification

Post-treatment windows — like the channels opened by microneedling or LaseMD Ultra™ — allow serums, growth factors, and ampoules to penetrate deeply and amplify the cellular response.

Featured Combinations

Curated pairings designed by Dr. Bui for specific outcomes.

The PH Thermal Sweep

XERF™ + LaseMD Ultra™

The signature PH Med pairing. XERF™ delivers deep structural radiofrequency tightening while LaseMD Ultra™ refines the surface — texture, pigment, and glow. Deep foundation meets surface perfection.

The Glow Protocol

Microneedling + Growth Factor Serum

Microneedling creates controlled micro-channels in the skin that dramatically increase serum absorption. Applied immediately post-needling, growth factors enter the dermis directly — amplifying collagen stimulation and accelerating healing.

The Regenerative Lift

LaseMD Ultra™ + Ampoule Infusion

LaseMD Ultra™’s fractional channels are open for a brief window post-treatment. Dr. Bui selects a physician-grade ampoule — Vitamin C, Hyaluronic Acid, Tranexamic Acid, or Growth Factor — based on your specific goals.

Image-Guided Refresh

Ultrasound Assessment + Injectable Correction

For patients with prior filler or complex anatomy, Dr. Bui uses real-time ultrasound to map existing product before placing anything new. This ensures new filler is placed in the right tissue plane with full visibility.

FAQ

Common Questions

Can any two treatments be combined?

Not all combinations are appropriate — timing, treatment type, and skin condition all affect whether two treatments can safely be done together or need to be spaced apart. Dr. Bui will assess what’s right for your skin during consultation.

Do combined treatments cost more?

Bookable system packages are typically offered at a value compared to booking each treatment individually. Custom protocols are priced based on what’s included — Dr. Bui reviews pricing in detail during consultation.

I’ve only had one treatment at PH Med. Can I do a system?

Yes. Many patients start with a system on their first visit. Dr. Bui will make sure the combination is appropriate for your skin’s current state and your goals before proceeding.

What is The PH Thermal Sweep?

The PH Thermal Sweep is PH Med’s signature combination: XERF™ radiofrequency for structural tightening paired with LaseMD Ultra™ fractional laser for surface refinement. It addresses both the foundation and the finish of the skin in a single extended session.
