Rimmel Lip Tint 300 Perpetual Plum

I'm a big sucker for advertisement and packaging. I get told frequently by friends and family that I impulse buy products due to whether they have a 'cool' advertisement campaign or whether I love the packaging. Now I'm not saying that the Rimmel 1000 Kisses Lip Tint had the best advertising or packaging but after watching copious amounts of Made In Chelsea on E4 whereby at every ad break that I remember they showcase the product. 

That's how I went about buying the product, Rimmel 1000 Kisses Lip Tint costs £6.99 from Boots. Before making the jump for the purchase I went into Boots at Bluewater before I had work and swatched different shades of this product on the back of my hand then after my 6 hour shift they were still there and that impressed me. I picked the colour 300 Perpetual Plum, which is a pink shade with slight purple undertones. 

For the first couple occasions of wearing it I loved it and didn't realise for a while that at the opposite end of the stick there was a lip balm. The product was quite drying on the lips and the balm takes away that effect which makes it look better. However, with the lip balm it makes the stain not last as long as it does without. 

The problem with this product is that I really want to love it and because the colour is great and it smells like plums too, which is a double bonus for me. There are other doubts like it is quite drying for my already dry lips and you need to make sure the pen lid is firmly on. I have had this product for about a month now and I have only used it on several occasions and have realised that the pigmentation of the stain has faded which is a bit of a bummer. Although it is only £6.99 so for the price the product you get is definitely worth that money and is good if you are in a situation where you can't touch up your lipstick. 

Has anyone got any tips on how I could get my pen working like new again?
