As you may know Liz Earle have introduced a range of cosmetics
all of which come in a fairly large shade selection that caters to all skin tones.
On the website each shade has a description that states what skin tones each shade would ideally suit
of course you can ignore the advice and pick whatever shade you desire.

"Soft and lightweight, our sheer gloss glides on smoothly and enhances lips with a luminous shine. 
Enriched with our own blend of avocado and shea butter to leave lips feeling soft.
Available in twelve shades."

I'm not a huge lip gloss fan at all, I favour lip sticks but as far as glosses go
this is fairly comfortable to wear, moisturising and not overly sticky.
It has a slight typical make-up scent but nothing offensive nor do you taste it when it is worn.
I was sent the shade Cherry which is listed as a suit all shade and I agree 
as the pigmentation is fairly subdued it works with your natural lip shade
but makes the lips a little rosier with a slight pinky red tinge.
If you like your glosses to be really pigmented this is not the one for you 
but for a subtle hint of a tint or to layer over another lip product!
In terms of wear I found this to wear for just a little over an hour.

Product Summary
Round Up - A Cherry red lip gloss that gives the lips a natural flush of colour.
Best For - Those that enjoy a natural effect lip gloss.
Pigmentation - (4/10) It is a sheer product so high pigmentation should not be expected.
Availability -  Liz Earle web store - link, £13.50/5ml
