I popped into Superdrug a while ago wanting to pick up the Montagne Jeunesse face masks, so I could use them before Eid. Unfortunately I didn't manage to find them (not sure if Superdrug have stopped selling them, or my local store was out of stock). In the end I bought 4 face masks from Superdrug's own range, as they were on offer 4 for 3. They are priced at 99p, which is the same as the Montagne Jeunesse ones and they have a large variety available, so you're likely to find one that suits your skin type.
So far, I've only tried the Tropical Cocktail Peel-Off mask (I would have tried the self-heating one if it wasn't so hot outside already!). This face mask smells mostly of coconut, although there is a fruitiness that I think comes from the mango. The instructions state to apply to a clean, dry face and leave on for 10-20 minutes, or until dry. It's quite sticky, so try to avoid making a mess when applying! Also, make sure to apply the mask in a even layer (I ended up with some dry areas ready to be peeled and other areas still sticky!). After removing the mask and washing off any bits that I had missed, my face felt refreshed, and ready to be moisturised. =)
Have you tried any of the Superdrug face masks? What did you think of them?
