Kerastase Nutritive 8H Night Serum

I spent way too long comparing options before pulling the trigger on this one. Zero regrets. It does exactly what it's supposed to do without any of the annoying quirks I dealt with on cheaper alternatives. Worth every penny.

Upgraded from the previous model and the improvements are noticeable right away. Smoother, quieter, better build. If you're on the fence about whether the newer version is worth it — yes, it is.

Was going back and forth between this and a competitor that costs 30% more. Went with this based on reviews and I'm so glad I did. The performance difference is negligible but my wallet is much happier.

Pros: looks great, ships fast, does the main job well. Cons: a few accessories feel cheap, and the setup process could be smoother. Net result: I'm keeping it and I'd probably buy it again, but I'd also understand someone returning it.
