A few months ago Sigma released these Lip Switches in a total of 5 different colours. After seeing some pictures on Instagram of these I decided to purchase a couple of them. Firstly I picked up Transcend which has a purplish blue finish and Pink Lotus which has a warm pinkish finish.
They are basically a holographic gloss can be worn alone but ideally designed to be worn over a lipstick and they create a unique shade. I quite like the packaging of these a clear tube with a matte white lid, the applicator is a brush styled applicator so application is not a problem.
As you can see above on the left is the Sigma Lip Switches on there own, in the middle is a matte lipstick shade so you can see what it is like before the Lip Switches were applied over and then on the right you can see how one lipstick shade can be changed into a unique shade. Each Lip Switch has a different colour holographic finish which means theres a shade for everyone.
Once these wear down they still seam to leave the holographic finish down rather than the gloss effect and the holographic effect both wearing out. These don't feel sticky on the lips at all but I'm not so much a gloss person so I just gently pat a tissue over.
