I've used them all and to me, they are all different. The newest one you love is the best formulation. Did you not order the TSV on auto delivery? That seems to be the only way to get the new version at this time. You can also check around online, I'm sure someone has it on ebay or elsewhere. Celebration Foundation SPF 50
The Your Skin But Better CC+ Airbrush Perfecting Powder SPF 50 is too powdery. Lots of flyaway powder if that makes sense. I also didn't think it melted into my skin as well as the new one. It also got chalky after a while.
The original was always too dark for me. I wear light in all versions. It always had a muddier look after a while for me and like the prior, just never melted into my skin. And yes, I tried various brushes, buffing, etc. If I use it with a super fluffy brush for a light touch up it works great, but NOT as my primary foundation.
All this said, I would hold out for the new Celebration Foundation SPF 50 if you like it. If you have an Ulta near you, they carry the last two I mentioned. Oh, and don't waste your time with the Celebration Illumination Powder unless you want to look like an alien.
I also HIGHLY recommend using a mix of the CC+ Cream and the CC+ Cream Illumination as liquid foundation topped with the Your Skin But Better CC+ Airbrush Perfecting Powder SPF 50. I put the Bye Bye Pores compact on after my cream sets first, then the CF SPF 50. Wears wonderfully!
