It is news that will bring a smile to the face of women who regularly subject themselves to Botox injections in a bid to banish crow's feet.
Scientists say the days of suffering needles for younger-looking skin could soon be gone after they developed a rub-on gel containing the powerful toxin.
A US study will test whether a one-off application can keep wrinkles at bay for a similar time to Botox injections, which usually last four to six months.
The toxin consists of relatively large molecules that do not easily cross the skin barrier and struggle to reach the muscles around the eyes. It means scientists have tried and failed for years to come up with an effective cream or gel formula.
Now Californian firm Revance Therapeutics claims to have come up with a formula that allows enough of the wrinkle-zapping poison to seep through the skin.
