This is a product from the body shops relatively new line of 'sweet lemon' based products. When applied lightly it leaves a beautiful sheen that melts onto your lips super quickly. It smells like lemon cheesecake which can only be a plus! Sometimes it does leave a weird lemonish sort of taste in your mouth but it goes pretty quickly.
It does cost around £4 (which is sort of steep for a lip balm) but I brought mine in a £5 set with a lemon body wash and exfoliating thing which I recomend getting because it works out cheaper.
Haha you can see the huge dent I've made in it already :) such a good lip product.
