Skin that
performs
at the source.
skintervene formulates at the cellular level. Our debut serum pairs Methylene Blue, a compound with over 140 years of scientific history, with eight supporting actives for skin that looks renewed, resilient and well-hydrated.
We intervene beneath it —
at the cellular machinery
that drives everything else."
Why mitochondria
change everything.
As skin ages, mitochondrial function declines. The organelles that power cellular energy become less efficient, and visible ageing is in part the consequence of this invisible slowdown.
Methylene Blue is redox-active: it cycles between oxidised and reduced states and can act as an alternative electron carrier. That is a different mechanism from conventional antioxidants, which is why it has drawn attention in skin research. Read the guide →
Meaningful inclusions, not token ones. Methylene Blue, Niacinamide, Ectoin, Tremella — each chosen for what it does, not how it reads on a label, with the reasoning published in our ingredient glossary.

Nine actives.
One precise purpose.
Redox-active antioxidant that can act as a mitochondrial electron carrier, a different mechanism from conventional antioxidants.
Vitamin B3. Helps minimise the look of pores, balance oil and support the skin barrier. One of the best-evidenced actives in skincare.

Hydrating, soothing polysaccharide that leaves skin feeling comfortable and supple.

Answered with
precision.
Methylene Blue is a synthetic compound first made in 1876. In skincare it acts as a redox-active antioxidant that can cycle between oxidised and reduced states, a different mechanism from conventional antioxidants. Full guide →
No. At the concentration used, Methylene Blue is effectively colourless in the gel base and does not stain skin, fabrics or bedding.
It is fragrance-free and designed for all skin types, with Ectoin and Centella for comfort. As with any new active, patch test first. If you take prescription medication, read our safety guide.
Skin feels more hydrated from the first use. Give texture and tone 4–6 weeks of consistent daily use, and judge the full effect at around 12 weeks.
