I am using it for a few weeks (close to a month) now and so far I am loving it. Right from the first use I noticed instant hydration from this product. It helped alot with my dry patches from tretinoin and winter combined.
It was instant releaf and hydration to heal my cracked and flakey skin. Since using it I did not have flakiness from tret (which i did have before). Im using it twice a day because my skin needs hydration and it seems like this is doing wonders for me regarding hydation.
This serum is so lightweight and watery and absorbs very easily into my skin. Im placing it after toner/essences as a first serum (if layering serums).
Since im using it twice a day (1 pump in the morning and 2 pumps in the evening - for entire face and neck) it looks like i will finish the bottle quickly (i believe it will last aprox.2 months, 2.5 m tops), but I believe it is worth the money and will repurchase it.
