# Skintervene > Skintervene is a UK skincare brand making advanced mitochondrial skincare. Its single product is the Cellular Renewal Serum with Methylene Blue (40 ml, £44.99), formulated and manufactured in London under UK cosmetic regulations. Skintervene formulates around cellular energy metabolism rather than surface effects alone. The hero ingredient is methylene blue at cosmetic concentration, supported by eight further actives: niacinamide, ectoin, tremella fuciformis extract, N-acetyl glucosamine, centella asiatica, green tea extract, beta-glucan, and squalane with panthenol. The formula is fragrance-free, vegan and cruelty-free. Skintervene states its evidence position openly: topical methylene blue is mechanistically well characterised but clinically young, supported by laboratory and reconstructed-skin model data rather than large controlled human trials. Skintervene makes cosmetic claims only and does not make medicinal claims. ## Product - [Cellular Renewal Serum with Methylene Blue, 40 ml](https://www.skintervene.com/products/skintervene-cellular-renewal-serum-with-methylene-blue-40-ml): The brand's only product.
