Non-Surgical Lifting: Combining PDO Threads, Microneedling, and Skin Tightening for a Youthful Profile

The Rejuvn8 Aesthetics Med Spa Approach to Skin Laxity in Rochester

Welcome to Rejuvn8 Aesthetics Med Spa in Rochester, NY.


As the facial structure ages, we experience laxity, which is characterized by the descent of tissue and the noticeable loosening of the skin's supportive scaffolding. At Rejuvn8, we utilize: PDO Threads, Microneedling, and Radiofrequency (RF) Skin Tightening. Each modality provides a distinct mechanism of support and dermal remodeling, allowing for fully customized, integrated treatment plans.



PDO Threads: Immediate Lift and Structural Scaffolding

Polydioxanone (PDO) Threads: The Science of Mechanical Lift and Collagenesis


Target: Moderate to Severe Skin Sagging and Specific Contouring

PDO Threads are dissolvable sutures made from a synthetic, biocompatible material (Polydioxanone). They offer a unique dual-action mechanism by providing both immediate physical support and long-term biological regeneration.


  • Mechanical Lift (Cog Threads): Specialized Cog Threads feature tiny barbs or cogs that anchor into the subcutaneous tissue layer. When the thread is inserted and then gently tensioned, it creates an immediate physical pull and lift, effectively repositioning sagging jowls, tightening the neck, and defining the jawline.
  • Collagen Stimulation (Mono/Smooth Threads): Mono Threads (smooth, barbless threads) are often placed in a mesh-like pattern. Their mere presence in the dermis triggers a controlled micro-injury and subsequent inflammatory response. As the body’s healing process is activated, fibroblasts are stimulated to produce a supportive lattice of new Collagen and Elastin fibers around the dissolving thread.
  • Degradation and Longevity: The PDO material itself is safely and completely absorbed by the body over approximately six to eight months, leaving behind the newly formed, autologous Collagen matrix, which sustains the lifting and tightening effects for 1 to 2 years.

Microneedling: Dermal Reorganization and Texture Refinement

Percutaneous Collagen Induction Therapy (Microneedling)


Target: Texture, Fine Lines, Scarring, and Overall Skin Quality

Microneedling, or Percutaneous Collagen Induction (PCI) Therapy, utilizes specialized devices to create thousands of controlled micro-injuries in the skin, which is the most reliable way to initiate a massive, organized healing response.


  • Mechanism of Action: The Wound Healing Cascade
  1. Fine, sterile needles penetrate the Epidermis and enter the upper layers of the Dermis to a precise, controlled depth.
  2. This process triggers a biological wound-healing cascade, releasing multiple Growth Factors (like TGF-beta).
  3. These Growth Factors stimulate the migration and proliferation of Fibroblasts, leading to a significant increase in the production of new Collagen Type III (which eventually matures into stronger Collagen Type I) and Elastin.
  • Resulting Remodeling: The treatment causes dermal remodeling and reorganization of existing scar tissue, making it a foundation treatment for improving skin texture, reducing the appearance of acne scars, and minimizing fine wrinkles.


Radiofrequency Skin Tightening: Deep Thermal Remodeling

RF Skin Tightening: Harnessing Thermal Energy for Dermal Contraction


Target: Mild to Moderate Skin Laxity and Firmness

Radiofrequency (RF) Skin Tightening utilizes focused electromagnetic energy to create a controlled thermal effect deep within the skin's support layers without damaging the surface.


  • Mechanism of Action: Controlled Thermal Damage
  1. RF energy waves safely bypass the Epidermis and penetrate into the Dermis layer.
  2. The energy is converted into heat, raising the temperature of the underlying tissue to between 43 degrees Celsius and 47 degrees Celsius
  3. This specific thermal range causes two critical actions: Immediate Collagen Contraction (the existing fibers tighten, resulting in a subtle instant firming) and Neocollagenesis (the heat signals fibroblasts to initiate a deep, long-term wound-healing response to produce significant new Collagen and Elastin).
  • Synergistic Combination (RF Microneedling): Some advanced systems combine both Microneedling and RF energy. The needles create micro-channels, and the RF energy is delivered through the needle tips directly into the targeted deep dermal layer. This dual action maximizes the thermal effect precisely where Collagen formation is most critical, offering superior results for deep laxity and scar remodeling.
