The best there is would not use anything else a bit pricey but does the job 

So I had a small sample vial of this I got from an ad on Instagram. I’ve tried two other hyaluronic acid serums in the past, one cheapest (you know it) and another I guess mid range. I found both to be sticky and make my face feel dirty and also not particularly hydrating.  THIS is so good! It made my skin so hydrated and radiant even just with a few drops. Only knocking a star off as it is so extraordinarily expensive!!!!!

This is very expensive but for me completely worth it. Its is the most effective hyaluronic serum I’ve used, I keep trying others but consistently come back to this one.

I recently tried the SkinCeuticals H.A. Intensifier Serum, drawn to its promise of harnessing the power of hyaluronic acid to enhance skin's hydration and texture. After several weeks of consistent use, I've formed a solid opinion on its performance. Starting with the positives, the serum has a lightweight texture that is both pleasing and easy to apply. It absorbs quickly into the skin without leaving any sticky or greasy residue, making it suitable for use under makeup or in combination with other skincare products. I also appreciated the packaging - the dropper allows for precise application, ensuring no product is wasted. In terms of its effectiveness, I noticed a slight improvement in the overall texture of my skin. The serum seemed to help with skin smoothness and provided a subtle plumping effect, which is likely due to the hyaluronic acid and the inclusion of other beneficial ingredients like Proxylane™ and purple rice extract. This combination works well to support the skin's hyaluronic acid levels and improve firmness. However, the serum falls short in one key area - moisturization. Despite its promise to intensify hydration, I found that it did not provide the level of moisture I expected from a hyaluronic acid product. My skin still felt the need for an additional moisturizer, especially in dryer areas. For those with particularly dry skin, this serum alone might not be sufficient to address hydration needs fully. In summary, while the SkinCeuticals H.A. Intens

Great product. Really moisturising and doesn’t make makeup peel. Very happy I tried it.
