I don’t think they shimmer at all! Unfortunately for me they just don’t work, the two lighter shades literally do nothing on my lips..and they feel drying

The rose tan is the only one that shows...something. I envy people with lighter lip colors and perhaps with lips that are in good condition. They definitely have no sparkles though, nothing at all like the lip shine (which I was also not a fan of but it’s a personal color match thing in that case).
I really wish they offer samples. Like others have said makeup is super personal...I do think Rose Tan is the safest choice out of these three for sure, I’d start with that one! Hope it works for you.
