I enjoyed using this serum. Has slightly viscous texture and no scent. It is a bit tacky but one you apply a moisturizer ( which you will), tha tackiness is gone. Has many added ingredients not only to hydrate the skin but also Ceramide and Amino Acids to keep the water inside. It is the first time I have seen 3% HA in skincare product and definitely can see the lovely plumpness promised by the brand
