Out of the six shades available the two that most appealed to me were 02 Beauty Secret -
and 06 Make A Statement -
Beauty Secret is an everyday wearable pink whereas for me personally Make A Statement comes out much darker on my lips so would be one I would personally wear on probably a night out or if I was going for dinner.
You can see the comparisons on the swatches below -
On the lips these don't come out terribly sticky and are fairly comfortable to wear however the only problem for me is I have to keep topping up as it's not very long lasting and tends to noticeably fade especially with Make A Statement as it's darker. To combat that problem I tend to wear a lip liner underneath so it's not as visible when it is fading but for the price I can't really complain!
Essence is available from Wilkinson and Superdrug - where I bought mine :-).
