I've seen this lipstick around for years. I remember being much, much younger and I would always swatch this lipstick when in a Boots or Superdrug. So it was really about time I picked it up.
So the idea behind this is that it applies clear to your lips and change colour depending on the natural alkali levels of your lips. It's an easy one to throw on like a lip balm but then it leaves a pink coloured stain on your lips all day long. I also really like the colour it turns on my lips, I think it is a really pretty pink which really suits my complexion. It's definitely worth a try and it's such a fun product, not sure how I'd feel about getting it out in public though and whacking it on!
