I love this product! It gives instant hydration and a dewing glow. I prefer using this product at night so I don't mix it with any other products like makeup

Cetaphil Optimal hydration serum is a game-changer for my dry skin. My face looks so much smoother, moisturized and healthier. Its lightweight texture absorbs quickly and doesn't feel greasy. I will definitely buy again.

I have very sensitive skin and every mosturizer I use leaves my face feeling hot. This one is amazing though. I have been using it for 3 weeks now and it has given my skin such a soft smooth look. My moisture barier has really been strengthened and I have never felt so refreshed, and so smooth after a moisturizer. I'd suggest this to anyone looking for some facial hydration & smoothness.

I used to love this product, but cetaphil has now added fragrance to the serum. Horrible for my sensitive skin. I am unsure why they made this change - the product was perfect before!!

The optimal hydration illumination lotion serum is phenomenal! I use this daily just before applying my makeup every morning. It is a nice added glow and base for my skin. It is smoother on my skin and fast and easy to apply

I have been using this new product for 3 weeks and i am very satisfied with the results I have seen thus far. I am 62 years old with very sensitive skin and have uneven pigmentation on my face. I also have oily skin with occasional acne breakouts. I use this Serum after using the Cetaphil cleanser and I am thrilled that I haven't had any skin reactions to it. Well done Cetaphil for introducing this great product! I will definitely continue to use it going forward. I am also going to try the new eye Serum as well.

This serum is really good and safe on sensitive skin but I can't get past the smell. It reminds me of the pink hand soap in public washrooms

j'ai eu la chance d'avoir un échantillon de ce produit et dès la première utilisation, je fus charmée! un produit léger, sans odeur qui convient parfaitement à ma peau. Moins cher que les produits que je me procurais au rayon des cosmétiques. Je le recommande à tous!

I have bern using Cetaphil products for over one year now. I have extremely sensitive skin and Cetaphil meets all my needs for complete skincare. The Optimal Hydration cream is a new product and I absolutely love it. It feels silky and my skin glows after application. I use the whole range of Cetaphil products including soap, day and night creams, cleanser and facial wipes. Thank goodness for Cetaphil

I absolutely love the Optimal Hydration Illuminating Serum! I am 56 years old. I use to struggle with dry skin. I use the serum daily after I have washed my face. This serum glides on easily. There is no scent. I like to follow with the Cetaphil Optimal Hydration Daily Glow Cream. When my skin is dry my wrinkles are more prominent when I wear foundation. I am extremely pleased with the softness of my skin and the reduction of fine lines.
