not sealed?
Been using the ampoule every other night for 2 months now. bottle comes without a sticker seal and the bottle isn't full to the brim, see photo (not an issue, just left me a little perplexed ^^')
bought it on a whim because of lim bora studio purple's review without reading about the whitening part (that's my bad). Don't like whitening products, that's why I don't use it every night but i figured using it every other night would help even out my complexion -- which it did!
I use 5 drops to cover my face, neck and décolleté.
I make sure to apply sunscreen diligently the next day (even more so than per usual).
Definitely lasts a long time. (see photo for content left after 2 months use)
