Personally, I like the recyclable box for packaging of this serum. I also like the dropper because I think it's hygienic. However, one thing I could not like is the smell. As you know, I have a very sensitive nose and when I am using a certain product, I have to consider if it has a scent or fragrance because it might irritate my nose. On the other hand, I like the gradual change it gives on my skin.
