Great hydration with no sticky feeling.
I love this serum. Caudalie S.O.S Hydrating Hyaluronic Acid Serum feels very light on the skin but gives amazing hydration. It absorbs quickly, doesn’t feel sticky, and leaves my skin soft and plump. Perfect for daily use, even for sensitive skin. I’ve noticed my skin looks fresher and more hydrated since I started using it.

disappointed
I was looking forward to using this product but I have felt disappointed, the texture is too liquid and my skin does not feel hydrated at all. In fact it leaves a residue and if you touch your skin after use the serum flakes away. I am a big fan of caudalie and love the ethics behind the brand but this item is a let down.

Best everyday serum around!
I have been using this product for a couple of year now and love how it makes my skin feel so hydrated especially in winter.

The only thing that works for my dry skin
This serum is my HG, the only thing that keeps the skin around my nose from flaking.

Caudalie's best product
Seriously. I've tried everything and love all of their products, but if I run out of this, I start losing my mind. If I could take one skincare product to a deserted island, this is it. Used it for 15 years now. Please don't change it.

Beauty in a bottle!
This product has never broken out my problem skin, only hydrates where needed and doesn’t over hydrate my t-zone. I think of this serum as my beauty in a bottle! I have used it for an entire year now; through all 4 seasons and it has never disappointed me. My absolute favorite product. I am now 54, before this product, I would still get the occasional blemish with both very dry & very oily skin issues. A year later & it has calmed down both issues! I love Caudalie! I use it daily and will never go without. Thank you for creating my beauty in a bottle. ❤️
