Most people have heard of glycerin, as it's got so many different uses, but did you know that it's also really good for your skin? Glycerin is what's known as an 'humectant', which means that it attracts water, making it an ideal ingredient in moisturiser. It's also an emollient, says Dr. Alexandrides, a Harley Street surgeon. He says 'This means that it is able to form a protective layer over where it is applied and thus retains the moisture that has been drawn into the skin, resulting in softer, smoother skin. This prevention of moisture loss will also strengthen the skin's barrier function, keeping toxins and bacteria from getting into the skin, meaning that the chances of inflammatory problems such as Eczema and Psoriasis are reduced.'

We've written before about how the beauty industry is often influenced by trends, just like the fashion industry, and trends of new wonder-ingredients pop up on an almost weekly basis. With brands like Elemis, Decleor and Dermalogica, however, it takes a lot more than 'trends' to influence what they put in their products, so when something like argan oil does make an appearance, you know it's really effective.

Having a daily skin routine is important, but sometimes we need an extra little boost to get our skin back to its best. Rather than going for expensive (and potentially painful!) non-invasive procedures, there are things you can use which can improve your skin dramatically in just five minutes - masks! We've trawled through our products to single out the best masks, and we thought we'd share our favourites with you.
