I also got this recently - a good three sachets that I could use up to an entire week.
I like serums for a start - as their texture is light and if they are good they will not clog my pores.
I had been using the previous Lanncome Absolue Serum - in the white box and white heavy glass pump bottle (that was called Anti Taches - an Anti spot serum, still available & visible on the Lancome website) but is now d/c.
It was nice but did not do a lot against my brown melasma.
This new Absolue is meant to replace that old one - I was told by the SA when I was looking for a repurchase of that Absolue AntiTaches.
Well, with the new one, so far so good.
I cannot report on spot diminishing (as 3 samples are way too few to have some result!) but the serum is very nice: promptly absorbed, leaves your skin fresh and glowing. It really sinks in, and you can then apply other treatments.
I applied this serum alone at night as it's still very hot here and I do not want to overload my skin with many products in this hot weather...
This serum did a perfect job alone, skin was perfect the morning after - no oliies, no pimples, no dry skin, a nice glow.
I will consider purchasing a full bottle - the price tag is quite high though!
