Purpose
Why this formulation exists
Plexus Lumbalis DUO is documented as a cutaneous topical composition for the lumbar application field. This summary is maintained by the documentation team and updated with each revision of the record.
Why this record exists
Covers a continuous surface path from the lumbar paraspinal strip to the anterior thigh field.
Neurocutaneous region it was designed for
Thoracolumbar neurocutaneous zone · Lumbosacral neurocutaneous zone
Anatomical interface it addresses
Thoracolumbar junction and lumbar plexus projection field, extending toward the anterior thigh.
Clinical philosophy
Formed within the psoas major from L1–L4, the lumbar plexus projects onto the lower abdominal wall, inguinal line and anterior and medial thigh.
- Cutaneous topical composition; the application field is defined by the treating professional.
- Application is documented per session so routines remain comparable over time.

Composition
Formulation architecture
The composition is documented as a map rather than a list. Every constituent is recorded with the function it carries, the reason it is present in this field, how it relates to the rest of the composition and the cutaneous topical formulation category it belongs to.
- 01Aqua base
Aqua
Carrier system
- Functional role
- Carrier phase
- Formulation purpose
- Sets the water phase that determines spreadability across a defined surface field.
- Interaction within the composition
- Holds the humectant fraction in solution and carries the emulsified lipid phase evenly over the zone.
- 02Glycerin
Glycerin
Humectant
- Functional role
- Moisture binding
- Formulation purpose
- Keeps the applied layer supple so the same field can be worked repeatedly without dryness on the skin surface.
- Interaction within the composition
- Balances the emollient fraction: the humectant governs the water phase, the emollient the lipid phase.
- 03Shea butter
Butyrospermum parkii butter
Emollient
- Functional role
- Skin-feel and occlusive body
- Formulation purpose
- Gives the texture enough body to stay on the applied zone rather than running along the hairline.
- Interaction within the composition
- Carries the lipid-soluble antioxidant fraction and slows the evaporation of the water phase.
- 04Panthenol
Panthenol
Conditioning agent
- Functional role
- Surface conditioning
- Formulation purpose
- Documented as a conditioning constituent of the cutaneous topical base; contributes to a smooth, non-tacky finish.
- Interaction within the composition
- Water-soluble; works alongside glycerin in the same phase without altering the emulsion.
- 05Tocopherol
Tocopherol
Antioxidant stabiliser
- Functional role
- Formulation stability
- Formulation purpose
- Protects the lipid fraction over the shelf life of the record so successive batches stay comparable.
- Interaction within the composition
- Dissolved in the shea fraction; stabilises the constituents it is dispersed in rather than acting on the skin.
Reading the map
Constituents are grouped by formulation category: a carrier system that governs spread, a water phase that governs feel, a lipid phase that governs stay-time, and stabilising constituents that keep successive batches comparable. Interactions describe the composition only; no physiological effect is asserted.
Cutaneous topical formulation rationale
The formulation is built for reproducible application on the documented zones: a texture that spreads thinly, a controlled sensory profile and a composition suitable for repeated professional use.
Representative composition overview. The full INCI listing is published in the composition index.
Philosophy
Formulation philosophy
Formulation philosophy: composition is selected for a defined surface field and a reproducible application sequence. The record documents composition and application only; no physiological or therapeutic mechanism is claimed.
Formed within the psoas major from L1–L4, the lumbar plexus projects onto the lower abdominal wall, inguinal line and anterior and medial thigh.

FAQ
Frequently asked questions
Is this a medicinal product?
No. SIRIAM formulations are cutaneous topical compositions. They are described by application region and composition, not directed at a therapeutic indication but rather at regulation of the nervous system. EMG validation will need to support this further in the future.
Who determines the application region?
The region is identified by a healthcare professional using anatomical landmarks and surface maps. Our documentation supports that conversation.
Can the formulation be combined with other routines?
Combination and sequencing are decided together with the treating professional. We document composition, application and response.
