I would like to buy this product for a very long time. I heard so many good things about it. So finally I ordered. The packaging and the bottle are very impressive 5*****. The ampoule format is very useful because I could decide how many would I like to use. For me there is no scent at all. I have klairs serum before and that one is more liquidish, this one is thick but not sticky at all. It has brownish color, it absorb very quickly, but it leave a very smooth skin after use. I know that it is firstly good for anti-aging and not for acne problem, and I am at the end of twenties, but I think it's a highly recommend product for everyone. So dont hesitate to order it!;)
