I give this product 4/5 thumbs up. I really like it.
The first time I used the Advanced Night Repair in a small sample, I was quite impressed. That convinced me to invest in a set of Estée Lauder products that contained this serum to get a chance to try it a bit longer among other products before committing to a full size.
Packaging is O.K. What I am not a big fan of is the way to dispense it. There is no dispenser and if you are not careful you might waste some precious product. Maybe the full size comes with a pump, but this smaller size that comes with their sets did not have it. It is rather compact and light for traveling.
The product is one of those products where you see something happening on your skin. Do not expect anything dramatic, those products do not exist or the effect is just momentarily. This is a product that has a positive on your skin and almost from day one. I really enjoy it and it seems it is a good investment if you want to look as young as possible. Your skin looks more alive, well nourished. It is expensive, as many high end brand serums are. If you are interested in trying it, ask for a small sample. If you think you might like it, you can always invest in one of their kits that come with it before investing in a full size product, just as I did.
Would I buy this again (and in full size)? Yes.
