Botox is used cosmetically to banish wrinkles

Muslims in Malaysia are going to have to learn to live with their wrinkles, after the country's top Islamic body ruled against Botox injections.

The council decided that the serum contained prohibited substances, including those derived from pigs.

At the last meeting of the National Fatwa Council, Malaysia's top Muslim clerics decided to ban black metal music - a kind of heavy metal.

They also ruled that it was alright for Muslims to eat cheese.

But they could not make up their minds about Botox.

Now they have come down against it, amidst fears that it contains pig products.

Amongst Muslim Malays, eating pork or coming into contact with pigs is a greater taboo than drinking or adultery.

The ruling is expected to find its way into Malaysia's Islamic laws.
