Polishes used:
Blackheart Beauty Shimmer Satin Matte [previously swatched], 2 coats
Sinful Colors Kylie Trend Matters Konstellation [previously swatched], 2 coats
Geesh, the title of this is a flippin’ mouthful, isn’t it? In a Facebook group I’m in, there was a suggestion to compare this Blackheart Beauty to an older Sinful Colors. Let’s see how they compare in the bottle!
So obviously, they look really close, maybe the BHB a little darker?
The BHB is on my index and ring fingers, the SC on my middle and pinky fingers. Now this is 2 coats of each without top coat. The BHB has more of a chalky matte finish while the SC is more of a satin matte finish.
The SC has a more sheer and thinner formula while the BHB has a thicker formula but dries way faster.
Just a few more photos to show differences. The BHB on the nail is slightly darker as well, and maybe leans a bit more purple than teal. Otherwise the differences really are imperceptible.
If you ever have any comparison suggestions for me, please feel free to shoot me an email or leave a comment! If I can, I’ll try to do a comparison post.

These are fairly similar and I like both. I haven’t purchased a Sinful Colors in ages.
