Incredibly hydrating but unbearable scent.
Size: 1.3 Ounce (Pack of 1)
I love all Avène skin barrier creams, recovery lotions and i just purchased this "Hydrance" cream. Texture is nice, it's unbelievably hydrating but the scent is overwhelming. It caused me a headache. So I decided to return it. Then I thought I'll give it another try and Oh my.... For the love of God, remove that awful scent. The reason I love Avène product is because theyre unscented, except this one I guess :/

Perfect Statue
Color: Venus - Large Antique, Color: Venus - Large Antique
This Venus De Milo statue is gorgeous. It is very sturdy but not too heavy…….. it appears heavier than it is which I adore since it is a statue. It has an “aged” coloring around the facial features and intricate details which makes it more authentic looking. I love Greek mythology and this piece is a perfect addition to my living room decor. Definitely worth the price.

Just perfect for that small nook on your bookshelf.
Color: Venus - Large Antique
A beautiful bust small enough to display in a small nook area of a shelf. It isn’t a masterpiece, but it is definitely worth the value for the money.
