Madonna has been keeping her skin looking youthful by trying out a new clay face mask from her skincare line.

The 55-year-old superstar, who recently launched Japanese brand MDNA, has posted a series of close-up selfies on her Instagram page showing off the results of her home pampering session using the new products.

She posted one snap of herself with a grey mud mask smothered on her face, along with the caption: ''Trying out the new Clay Mask from MDNA skin care line! Lets see if it works! #livingforlove, (sic)''.

The 'Hung Up' hitmaker also posted a product shot of the mask and later showed her followers the amazing results.

She shared a photograph of herself with glowing skin and no make-up, wearing a grey patterned paisley hat, along with the caption: ''Lovely and glowing! Yaaaasssssss it werks! #unapologeticbitch. (sic)''

The blonde star had already kicked off the product's launch with a dreamy black and white video and spoke passionately about the skincare brand.

In the video, she said: ''I've spent hours on it. Months on it. Years on it,'' and mused, ''Your amber silken skin smells of your mind.''
