Skin that
performs
at the source.
skintervene formulates at the cellular level. Our debut serum harnesses Methylene Blue — a compound with over 140 years of scientific history — to support the mitochondrial function that drives skin renewal, resilience, and repair.
We intervene beneath it —
at the cellular machinery
that drives everything else."
Why mitochondria
change everything.
As skin ages, mitochondrial function deteriorates. The organelles that power cellular energy production — ATP synthesis, repair cycles, resilience responses — become less efficient. Visible ageing is in part the consequence of this invisible cellular slowdown.
Methylene Blue is a redox-active compound capable of cycling between oxidised and reduced states, functioning as a mitochondrial electron carrier. This allows it to support cellular energy production in a way conventional antioxidants cannot — intervening at the source.
We formulate at therapeutic concentrations — not token inclusions. Every active in our formula is dosed to the threshold where clinical evidence begins. Methylene Blue, Niacinamide, Ectoin, Tremella — each chosen for what it does, not how it reads on a label.
Cellular
Renewal
Serum
An antioxidant-rich gel-serum engineered at the cellular level. Powered by Methylene Blue to support mitochondrial function, skin renewal, and barrier resilience — formulated for skin that performs, not just survives.
Nine actives.
One precise purpose.
Redox-active mitochondrial electron carrier. Supports cellular energy production and antioxidant defence at the source.
Vitamin B3 — minimises pores, regulates sebum, strengthens barrier. One of the most evidence-backed actives in skincare.
The beauty mushroom — forms a moisture-binding film with hyaluronic acid-like hydration properties.
Natural extremolyte that forms a hydration shell around cells, protecting against UV, pollution, and environmental stressors.
Supports hyaluronic acid synthesis, suppresses excess melanin, promotes cell turnover for refined texture and tone.
Proven collagen-stimulating properties. Soothes inflammation and supports barrier function.
Rich in EGCG polyphenols — protects against UV-induced oxidative damage and supports skin clarity.
Penetrates the epidermis to stimulate collagen synthesis and accelerate wound healing.
Lipid-identical emollient and pro-vitamin B5. Locks in moisture and restores barrier softness without pore occlusion.
What skin
actually does.
"I've tried countless serums but nothing has worked like this. My skin texture has completely transformed in 6 weeks. The Methylene Blue really does something different."
"As someone who researches longevity science, I was sceptical. Three months in and the evidence is on my face. Pores are tighter, tone is noticeably more even. This is the real thing."
"Sensitive skin here — I was nervous about Methylene Blue but it's been completely calm. The Ectoin does its job. Genuinely the best serum I've used. Better than Aesop, better than SkinCeuticals."
Answered with
precision.
Methylene Blue is a synthetic phenothiazine compound first synthesised in 1876. In skincare it functions as a redox-active antioxidant and mitochondrial electron carrier — supporting the cellular energy processes that decline with skin ageing. Unlike conventional antioxidants, it can cycle between oxidised and reduced states, making it uniquely effective.
No. At the concentration used in our formula, Methylene Blue is effectively colourless once incorporated into the gel base. It will not stain skin, fabrics, or bedding.
Yes. The formula is designed for all skin types. Ectoin, Centella Asiatica, and Allantoin provide soothing and barrier-supportive benefits. Completely fragrance-free with no known sensitisers.
Hydration benefits within 24–48 hours. Structural improvements — texture, barrier resilience, tone evenness — at 4–6 weeks. Methylene Blue's mitochondrial effects are cumulative and best assessed over 90 days.
Manufactured in London SW19. Dermatologist-reviewed, patch-tested, produced in full compliance with UK Cosmetics Regulations. Full batch traceability on every unit.
