Changed formula?
Dear Osea, did you change the formula of the Hyaluronic Sea Serum? I've used this product for 2 years now and have loved it until the last bottle I purchased.

This is expensive but when I am put it on my face, I am saying: this is so worth the money, this is worth every penny, this smells so good, my face deserves this.” This is THE BEST facial oil I have tried and decided to use. One of Oseas best products in my opinion!
Try a sample if you can!

CONS: Its got an awful smell. I suggest sampling it first if thats something you arent into. It often pills if you use additional products with it. Like others have said, the applicator is a terrible design. The bottle is way too small for the price. PROS: the bad smell disappears when it dries. I have incredibly sensitive skin and this is one of very few serums that doesnt cause irritation. It feels very moisturizing without being oily. Not sure how to explain it, but the product feels incredibly clean on the skin. If the applicator was more functional and if there were more cost effective sizes, Id give it 5 stars.
