INFLAMMATION & HEALING
Inflammation is a controlled biological response that initiates tissue repair and regeneration.
In its acute form, it activates immune pathways, removes damaged tissue, and triggers regenerative processes.
However, when inflammation becomes chronic or dysregulated, it leads to continuous tissue degradation, extracellular matrix breakdown, and impaired cellular function.
This imbalance reduces the skin’s ability to regenerate and respond effectively to treatment.
Successful regenerative strategies therefore depend on supporting controlled inflammation while preventing persistent low-grade inflammatory activity.

CELLULAR COMMUNICATION
Cellular communication is the regulatory system that coordinates how cells respond to internal and external signals.
This communication occurs through signalling molecules such as growth factors, cytokines, and extracellular vesicles, including exosomes.
These signals control key processes such as inflammation, tissue repair, and regeneration. The timing, intensity, and balance of these signals determine how effectively cells respond to therapeutic interventions.
Disruptions in cellular communication — due to ageing, inflammation, or environmental stress — lead to uncoordinated responses and reduced regenerative efficiency.
As a result, even when structural components and functional cells are present, impaired signalling can limit meaningful regeneration.

EXTRACELLULAR MATRIX (ECM)
The extracellular matrix (ECM) is a dynamic structural and biochemical network that regulates cellular behaviour and tissue function.
It is composed primarily of collagen fibres (types I and III), elastin, and glycosaminoglycans such as hyaluronic acid, which together provide mechanical stability, hydration, and structural organization.
Beyond its structural role, the ECM functions as a signalling interface, influencing fibroblast activity, cell migration, differentiation, and tissue repair.
The integrity and organization of the ECM determine how effectively cells can respond to regenerative stimuli. A well-structured matrix supports coordinated repair, while a degraded ECM reduces cellular responsiveness and disrupts signalling pathways.

Fibroblasts
Fibroblasts are the primary functional cells of the dermis, responsible for synthesizing collagen (primarily types I and III), elastin, and key extracellular matrix components.
They regulate tissue structure, mechanical strength, and elasticity, and play a central role in wound healing and long-term tissue remodelling.
Fibroblast activity is influenced by signals from the extracellular matrix, growth factors, and inflammatory mediators. Their ability to respond to these signals determines the skin’s regenerative capacity.
With ageing or chronic inflammation, fibroblast function declines, leading to reduced collagen production and impaired tissue repair.
Effective regenerative strategies therefore depend not only on fibroblast stimulation, but on restoring the surrounding biological environment that enables proper cellular function.

Inflammation & Healing
Inflammation is a controlled biological response required for tissue repair and regeneration.
Balanced inflammation supports healing, while chronic inflammation leads to tissue degradation and impaired regenerative capacity.

Cellular Communication
Cellular communication refers to the signaling processes that coordinate cell behavior through growth factors, cytokines, and extracellular vesicles.
These signals determine how cells respond to stress, injury, and therapeutic interventions.

Extracellular Matrix (ECM)
The extracellular matrix (ECM) is a dynamic structural network that provides mechanical support and regulates cellular behavior.
It influences hydration, elasticity, and how cells respond to mechanical and biochemical signals.
