Aesthetic Product Technical Guide
Technical Reference for Aesthetic Practitioners
Keen Fillers provides structured technical information to help qualified aesthetic practitioners review product characteristics and match formulations with their intended applications.
This guide presents key specification categories including hyaluronic acid concentration, rheological characteristics, target tissue layers, active compounds, and storage considerations.
Professional-use information: This guide is provided for informational and product-reference purposes. Product use, treatment planning, injection technique, patient selection, and clinical protocols should be determined by appropriately qualified healthcare professionals in accordance with applicable regulations and the manufacturer's instructions.
1. Dermal Fillers — Hyaluronic Acid Rheology Matrix
Dermal fillers can differ significantly in their viscoelastic behavior, HA concentration, structural characteristics, and extrusion mechanics. Understanding these parameters can help qualified practitioners evaluate a product's intended tissue layer and application.
Product Category
HA Concentration
Rheology / G′
Target Layer
Common Indications
Fine Lines / Superficial
12–20 mg/mL
Low G′ — flexible, low resistance
Superficial dermis
Perioral lines, crow's feet, tear troughs
Deep Dermis / Mid-Face
20–24 mg/mL
Moderate G′ — balanced lift/cohesion
Mid-to-deep dermis
Nasolabial folds, marionette lines, lip augmentation
Sub-Q / Volumizing
24–26 mg/mL
High G′ — strong structural lift
Subcutaneous / periosteum
Cheek volume, jawline contouring, chin augmentation
The guide classifies fillers according to HA concentration, G′ characteristics, and intended anatomical layer.
Understanding G′
G′ (storage modulus) is a rheological indicator used to describe the elastic component of a gel's behavior.
Within this guide, the categories progress from:
Low G′ → Flexible / low resistance
Moderate G′ → Balanced lift / cohesion
High G′ → Strong structural lift
These classifications should be considered alongside the manufacturer's product-specific technical documentation.
2. Skin Boosters & Mesotherapy Formulations
Unlike volumizing dermal fillers, skin boosters and mesotherapy formulations are presented in this guide according to their active compounds, delivery characteristics, and primary intended actions.
Active Compound
Molecular / Delivery Characteristics
Primary Action
Protocol Listed in Guide
Non-Crosslinked HA
High molecular weight, unlinked HA
Deep dermal water binding, radiant glow
3 sessions spaced 4 weeks apart
PDRN / Salmon DNA
Polynucleotide matrices
Cellular repair, scar revision, collagen synthesis
3–4 sessions every 2–3 weeks
Exosomes & Peptides
Lyophilized extracellular vesicles
Intense cellular signaling, anti-inflammatory
Topical post-microneedling / RF
The source guide describes skin boosters as focusing on hydration, fibroblastic stimulation, and skin-quality refinement rather than conventional volumization.
Important: Protocols shown above are reproduced from the technical reference guide. Practitioners should verify the specific manufacturer's instructions, regulatory status, formulation, and applicable clinical requirements before use.
3. Cold Chain Compliance & Storage Reference
Proper storage and transportation are important considerations for maintaining product integrity.
Storage: 2°C–8°C
The guide specifies continuous cold storage and insulated thermal transportation configurations for liquid or freeze-dried botulinum toxin products.
Crosslinked HA Fillers
Storage: 2°C–25°C
The guide recommends keeping crosslinked HA fillers away from direct sunlight and preventing deep freezing in order to protect the stated gel crosslinking characteristics.
Biostimulators — PLLA / PCL
Storage: Room-temperature storage optimization
The guide states that reconstitution should follow the applicable sterile saline distribution model and the relevant product instructions.
4. Using Technical Specifications When Selecting a Product
For qualified practitioners reviewing products, the following specifications provide a structured way to compare formulations:
HA Concentration
Indicates the concentration of hyaluronic acid in the formulation.
G′ / Rheology
Provides an indication of the gel's elastic behavior and structural characteristics.
Target Layer
Identifies the anatomical tissue layer associated with the product category in this guide.
Intended Application
Provides examples of the common applications associated with each product category.
Active Compounds
For skin boosters and mesotherapy products, the active formulation provides additional information about the product's stated purpose.
Storage Requirements
Storage conditions should be checked before ordering, receiving, transporting, and storing products.
