✅ Cult classic patented formula which has stablized ascorbic acid.
✅ Instantly brightens skin, it is kind of magic. Also I think it lightened some stubborn acne marks (pih).
✅ Small sample bottle lasts a long time. I apply 4 drops everyday in the morning and it has lasted me over a month.
✅ Caused zero sensitivity.
✅ Lightweight texture sinks in without oily residue, played well with other products.
❌ Soooo expensive, but I guess you get what you pay for since it is worth the hype. To be fair though, I have not tried affordable alternatives like the Timeless Vitamin C. I have tried other vitamin C products but they did not yield as fast results, or caused sensitivity.
❌ Due to the ferulic acid, smells briny like a hot dog. At first I hated it but now I've gotten used to it and don't mind since the results make up for it.
