Most med spas offer individual treatments. But facial aging doesn't happen in one layer — it happens everywhere at once. Here's why going one at a time leaves you stuck.
Even medical-grade serums and retinoids can only penetrate the outermost skin layers. They improve surface texture and tone, but cannot address structural laxity, deep collagen loss, or volume depletion beneath the skin.
Surface-level onlyA single energy-based device tightens one layer effectively. But it can't simultaneously resurface texture, repair at the cellular level, and restore lost volume. You get improvement in one dimension while the others continue aging.
One layer addressedDermal filler adds volume, but it doesn't tighten lax skin, improve texture, or stimulate your body's own collagen production. Over-reliance on filler without addressing skin quality leads to an unnatural, overfilled appearance.
Masks, doesn't fixTreatment stacking isn't random combination — it's a physician-designed protocol where four complementary technologies are sequenced to target every layer of facial aging simultaneously.
XERF tightens deep structure. Microneedling + Rejuran resurfaces and repairs at the cellular level. PRP/PRF regenerates volume biologically. Together, they create a compounding effect no single treatment can match.
Each treatment addresses a different layer and biological mechanism. Together, they amplify each other.
Multifrequency monopolar RF reaches from the superficial dermis to the SMAS layer. Contracts existing collagen and stimulates deep neocollagenesis. The structural foundation of the protocol.
Controlled micro-injuries trigger surface collagen induction while Rejuran's polynucleotides accelerate cellular repair at the DNA level. Refines texture, pores, and tone from the outside in.
Your own concentrated growth factors stimulate fibroblast activity and biological volume restoration. Rebuilds what aging has eroded — naturally, without synthetic filler. Results last 12+ months.
This is why stacking produces results that no single treatment can match — every layer of aging is addressed simultaneously.
| Treatment | Primary Target | Mechanism | Timeline |
|---|---|---|---|
| XERF | Deep dermis + fibroseptal network | Thermal contraction + deep collagen remodeling | Immediate contraction; peak at 3–6 months |
| Microneedling | Superficial dermis | Collagen induction + skin thickening + product delivery | Visible in 2–4 weeks; optimal at 3 months |
| Rejuran | Cellular level | Polynucleotide DNA repair + elasticity + anti-inflammation | Progressive over 4–8 weeks per session |
| PRP/PRF | Subdermal tissue | Growth factor release + biological volume restoration | Gradual over 2–3 months; lasts 12+ months |
These results are from a PH Med patient who completed the full Thermal Stack protocol. The transformation spans the jawline, skin surface, and under-eye area.
Look at the jawline and submental area. Before: visible jowling and laxity — the jawline blends into the neck. After two XERF sessions: the jawline is sharper, the tissue beneath the chin has lifted, and there's a clean angle between jaw and neck.
This close-up shows the skin texture change. Before: enlarged pores, rough texture, visible sun damage, uneven tone. After: dramatically smoother skin, refined pores, more uniform texture, and a healthier overall tone.
Focus on the under-eye area and overall skin quality. Before: hollowing, texture irregularities, tired appearance. After: fuller under-eyes, softened hollow trough, and dramatically improved tone and hydration across the mid-face.
XERF's deep RF energy contracts the fibroseptal network to tighten jowling, redefine the jawline, and restore the clean contour between jaw and neck.
Microneedling with Rejuran resurfaces the skin from the outside in — shrinking pores, smoothing rough texture, and evening out tone across the cheeks and mid-face.
PRP/PRF growth factors regenerate volume in the tear trough, reduce dark circles, and thicken the delicate periorbital skin — all without synthetic filler.
The compounding effect of all four treatments improves hydration, elasticity, collagen density, and biological age of the skin across the entire face.
This isn't about doing more. It's about doing the right things in the right order so each treatment amplifies the others.
XERF targets the deep structural layer. Microneedling targets the surface. Rejuran targets the cellular level. PRP/PRF targets subdermal tissue. No layer is left behind — and that's why the results look complete, not partial.
XERF's deep tightening creates a firmer foundation for surface treatments. Microneedling creates channels that let Rejuran penetrate 300% deeper. PRP growth factors supercharge the collagen remodeling that XERF and microneedling initiated. The math isn't additive — it's multiplicative.
Because each treatment works through your body's own biology — stimulating collagen, activating repair pathways, releasing growth factors — results develop gradually and look natural. You look refreshed and sharp, not like you had a procedure.
The full protocol is delivered across multiple visits spaced 4–6 weeks apart. Each session takes 60–90 minutes. Most patients experience mild redness for 24–48 hours and return to normal activities the same day.
Because treatment stacking triggers actual biological remodeling — not temporary volume or surface-level improvement — results continue developing for months after the protocol is complete. XERF remodeling peaks at 3–6 months. PRP/PRF regeneration lasts 12+ months.
Your Thermal Stack protocol begins with a one-on-one consultation with Dr. Bui, where she evaluates your facial anatomy, skin quality, and specific concerns. Because Dr. Bui is a board-certified physician — not a technician or nurse injector working unsupervised — she can customize the stacking protocol to prioritize your most important areas and determine the optimal treatment sequence for your unique anatomy.
Every injectable treatment at PH Med is performed with ultrasound-guided precision, using real-time imaging to visualize the anatomy beneath the skin before, during, and after treatment. This isn't standard practice at most med spas — but it's standard at PH Med.
PH Med was among the first practices in Houston to adopt XERF technology, giving Dr. Bui extensive experience with the device's full range of applicators.
