£3 PAIN-FREE TATTOO REMOVAL

Got a tattoo that you now regret? There may soon be a gentler, cheaper alternative to laser removal. PhD student Alec Falkenham in the US has worked out how to harness a property of your body’s own immune system. He’s developed a cream that delivers drugs to white blood cells called ‘macrophages’ (Greek for ‘big eaters’), causing them to release the ink they took up in order to protect your skin during the tattooing process.
