I really REALLY like this product. I've been using it for YEARS. I also use the eye cream in this line, advanced night repair eye & for people with dark circles, puffs AND more dryness around the eyes than most eye cream/gel type products can handle, this eye product is for you! But I digress....
Advanced Night Repair serum has been in the Estée Lauder line as long as I can remember. My grandmother used it religiously & she passed at age 91 w/ glorious, even toned, smooth skin. I use ANR at night only but you can use it during the day. The serum is lightweight, doesn't feel heavy & smooths evenly onto the skin. It has a pleasant scent that comes from the ingredients in the serum, not added fragrance. It's kind of a light citrus-y, botanical smell, not at all overpowering.
As stated I use this first, after washing, toning, exfoliating, following with any other skin care, then moisturizer. I have acne prone skin & I'm approaching my 40's so anything to help protect my skin I'm all for! The main thing in this is antioxidant repair, protection from free radicals, etc., etc.. I gave it 5 lippes for how great the product is, my skin even after years of cystic breakouts, smoking & not drinking enough water or getting enough sleep my skin is smooth & even toned, firm around the jawline & circumference of the face. I know this product can't claim ALL the credit but for the 1 st line of defense, free radical & antioxidant damage, you can't beat it. I have it 5 lippes for price, because its not cheap, a 1.0 oz will cost you around 45-50, a 1.7 oz 60-70 range & the 3.4 is knocking at 100 if memory serves. The good news is it really last a long time. I use about 1/4 of a full dropper on my face/neck nightly, about 5 drops. That's all you need!
I gave it 4 lippes for packaging quality only b/c I'm not a huge fan of droppers in any skin care & if never fails that towards the end of the bottle you need to angle it & position the dropper "just so" to get the remaining product out. Other than that the package is fine, doesn't leak, pretty durable & the amber color of the bottle helps keep light out so your product stays fresher longer.
I read one reviewer state that she didn't care for the serum, that it might work better for only mature skins. In truth it's good for all skins, hers too. The antioxidant protection this product gives will help protect a younger persons skin from free radical damage they CAN'T see now, so I'd disagree that it's just for oldies ;) any one can use it & benefit.
People who liked & used Super Line Preventer from the now, defunct Prescriptives, (why Estée Lauder, WHY???) will like Advanced Night Repair, as its virtually the same product packaged differently. Right down to the scent. All I'm all I think this product is a win, I have gone through more than 1 bottle & will repurchase again. As far as I am concerned its the (one & only) shining star in Estée Lauders skin care line.
