The Evidence for Longevity Dynamics
Aging follows a sequence.
So we can address it in the right order.
Why skin aging occurs through six pathways.
Removing senescent cells. Promoting single ingredients. Waving bold slogans. The major brands are planting their flags one after another. But every one of them addresses only a single aspect of aging.
Targeting one cause does not stop the cascade. Skin aging advances through six interconnected pathways—and each one feeds the next.
Understanding these six pathways is where real skin longevity begins.
The Aging Cascade
Six pathways.
This is the sequence in which skin ages.
Available
ROS (Reactive Oxygen Species)
The origin of the cascade. When this goes unchecked, everything begins.
Reactive oxygen species (ROS), generated by UV exposure, stress, and environmental pollution, oxidize cells and DNA. This is the trigger that initiates the entire skin aging cascade. Controlling ROS means cutting the chain of aging at its root.
In Development
Chronic Inflammation
A slow fire ignited by ROS. The skin deteriorates before you notice.
When ROS accumulates, chronic low-grade inflammation takes hold inside the skin. Inflammation is also the breeding ground for senescent cells. Controlling the inflammation that produces senescent cells is a more fundamental approach than removing them after the fact.
In Development
MMP & Fibroblasts
Inflammation activates the enzymes that dismantle the skin's scaffolding.
Chronic inflammation activates MMPs (matrix metalloproteinases)—enzymes that break down collagen and elastin, dismantling the structural scaffolding of the skin. Simultaneously, fibroblasts, the cells responsible for producing collagen, begin to lose their function.
Available
Barrier Function & Collagen
The accumulated destruction by MMPs surfaces as wrinkles and sagging.
As collagen is lost, skin loses firmness and elasticity. Barrier function breaks down alongside it, reducing resistance to external stressors. When the barrier is compromised, even the most expensive ingredients applied topically have limited reach.
In Development
AGEs (Advanced Glycation Endproducts)
The skin stiffens with accumulation. Once formed, AGEs do not reverse.
AGEs, formed when sugars bind to proteins, crosslink and harden collagen fibers. Dullness, loss of elasticity, and an aged appearance are in large part caused by AGE accumulation. Prevention and suppression are the only strategies.
In Development
Senescent-Cell Accumulation
Here the chain closes into a loop. The accumulated burden pushes the upstream back up.
Oxidative stress (R), inflammation (I), and ageing itself increase the cells that remain in the tissue after they have stopped dividing. These cells release inflammatory substances and scatter enzymes that break down collagen, and the increased burden drives reactive oxygen species further up. The chain closes into a loop here. CHROSNOF treats this accumulating quantity as an independent axis and calculates it together with its effects on the other five axes.
The FABIRS Six-Axis Framework
Six axes. One structure. Managed together.
We refer to this structure as the FABIRS Framework—Fibroblast, Anti-Glycation, Barrier, Inflammation, Antioxidation, Senescent Cell Clearance.
S (Senescent Cell Clearance) is an independent axis and, at the same time, a hub with branches both upstream and downstream. Topical care covers the local level and inner care the systemic circulation, bridging the I and F axes.
We quantify how far each axis has degraded, then design formulations that address each pathway specifically. This is the structural foundation of every REGINA LOCUS LVXL product.
Skin Cross-Section & FABIRS Pathways
- F— Fibroblast
- A— Anti-Glycation
- B— Barrier
- I— Inflammation
- R— Antioxidation
- S— Senescent Cell Clearance
S Axis ／ Senescent Cell Clearance
S is a hub that branches into the other axes.
S｜Senescent Cell Clearance — Suppressing senescent cells and SASP. Topical care covers the local level and inner care the systemic circulation, bridging the I and F axes.
As we age, cells that have stopped dividing but remain in the tissue — senescent cells — gradually accumulate. These cells release inflammatory substances and scatter enzymes that break down collagen, which is known to affect the healthy tissue around them. CHROSNOF treats this accumulating quantity as an independent axis and calculates it together with its effects on the other five axes.
Stock layer and rate layer
CHROSNOF separates its state variables into two layers by their nature: quantities that accumulate over time (stock) and quantities that describe how fast something is flowing right now (rate). AGEs and senescent cells (S) belong to the stock layer — once they build up, they do not readily return. Reactive oxygen species (R) and inflammation (I) belong to the rate layer, rising and falling quickly as conditions change.
S is a hub
S has branches both upstream and downstream. Oxidative stress (R), inflammation (I), and ageing itself increase S, and the increased S in turn drives R further up. That this exchange forms a closed loop is a central point of the CHROSNOF v14 design. The intuition that lowering the senescent-cell burden eases several downstream axes at once is expressed, within the model, as a structure in which S enters multiple terms in common.
Why we placed it as an independent axis
Because the substances senescent cells release are inflammatory cytokines, they appear to overlap with inflammation (I) at the level of observation. To avoid counting the same thing twice, CHROSNOF draws a clear line between the layers: S is the burden on the cell side, I is the concentration on the secretion side.
Patent pending (JP 2025-285457)
The effect of topical application on senescent cells in human skin is an area where verification is still in progress. CHROSNOF treats S as an axis within its calculations and makes no numerical claim regarding amounts removed or states reached.
Formulation Design Based on FABIRS
The line-up, and the order of use.

Cleansing
Mousse Purifiante Lumière
Not a cleanser that only removes. It calms oxidation and inflammation while it washes and leaves the barrier intact, setting the condition in which everything applied after it can work.

Essence Sérénité Profonde
A formulation dedicated to controlling chronic inflammation — an upstream intervention into the pathway that breeds senescent cells.

Concentrate
Concentré Revitalizon Avancé
10% fullerene. Controls ROS—the origin of the aging cascade—at the upstream level. Cuts off the source of senescent cell formation before it begins.

Crème Régénération Temporelle
A compound formulation that activates fibroblasts while holding glycation and senescent cells down. It closes the routine on the state the earlier steps have set.

Tisane Lumière Intérieure
An inner cup covering the systemic circulation that topical care cannot reach. Designed as the counterpart to care applied from the outside.
How We Differ from Senolytics
Upstream control, not downstream cleanup.
Senolytics—the removal of senescent cells—has attracted significant attention. Senescent cells trigger chronic inflammation (SASP) and damage surrounding cells. The approach itself has scientific merit.
But we ask: why do senescent cells form? The answer is chronic inflammation and ROS. What REGINA LOCUS LVXL chose was to address the very cause that gives rise to senescent cells. Rather than extinguishing the fire, we create conditions where fires are less likely to start. This is what we call skin longevity.
