I've had this Montagne Jeunesse mud face mask since November and still have plenty of product left in the tube. I paid around £6 for it in Boots which is a fantastic bargain considering the sachets are usually around £1.50-£1.99. I use this weekly as a special treat for my face and to also get all the dirt and nasties out my pores.
It says on the tube upto 10 uses but i've used this now around 18 times and it still has plenty of product left which is a plus!
This was the only one they sold in the Boots store I went in and it says its for ultra deep pore cleansing and the description on the back reads 'invigorating real dead sea minerals, seaweed and lavender help relax, calm and soothe. Impurities are drawn out and blocked pores are opened leaving skin ultra deep pore clean'
You are instructed to leave this on around 10-15 minutes then rinse it off with warm water and you're left with amazing, soft, freshly cleansed skin.
I think everyone should treat their skin at least once a week... I normally have a special 'pamper night' where I have a nice hot bubble bath (philosophy bubble bath mmm!), face mask, hair treatment, tint eyebrows, exfoliate whole body and face, moisturise whole body and face, nails etc.
