Ageing is not written in our genes.
Less than 3% of ageing is genetic. The rest is shaped by epigenetic factors - stress, environment, lifestyle, nutrition. CEL™ was created to address these epigenetic shifts, supporting the skin’s ability to function, regenerate, and endure.
Targeting the root mechanisms of ageing
CEL™ is designed to act on 10 key cellular markers of ageing. These include:
- Telomere protection – safeguarding the DNA “caps” essential for longevity.
- Stem cell preservation – maintaining the skin’s regenerative potential.
- Mitochondrial vitality – enhancing cellular energy and repair mechanisms.
- Autophagy stimulation – promoting healthy renewal and recycling of damaged cells.
- Barrier integrity – reinforcing tight junctions and defence mechanisms.
- Microbiome balance – supporting skin’s natural ecosystem.
Unique. Proprietary. Patent-pending.
CEL™ is Skin Diligent's proprietary bioactive complex designed to slowing down ageing.
Rooted in advanced epigenetic research, CEL™ goes beyond targeting visible signs of ageing on the surface. It works at the cellular level to extend skin healthspan and support long-term resilience.
A blend of botanical biotech extracts, peptides and exosomes train the skin to deliver targeted longevity signals to preserve its youthful capital and extend its vitality.
- In clinical testing, CEL™ increases skin firmness by 70% & reduces wrinkle depth by 25% compared to placebo.
- In vitro and in cellulo evaluations, CEL™ inhibits 100% of collagenase and boosts pro-collagen levels by 43%. In other words, CEL™ helps protect the native collagen and support production of new collagen.
'Zombie cells' vs CEL™
Senescent cells or "zombie cells" are renegade cells at the end of their life cycle. Their presence produces inflammatory factors that damage other cells and speeds up ageing.
Instead of targeting zombie cells, Skin Diligent's CEL™ actively supports the cells during their life cycle to stay healthy and pushes the senescence as far away as possible. Our approach is to optimise the health of skin cells while they are active, and not wait for the cells to reach inflammatory senescence.
“True progress in skincare is formulating products from the cellular point of view. Any ambiguity can be answered scientifically if we ask what the product or ingredient does to the skin cells.”
