I can't go without my La Roche-Posay HYALU B5 Serum!
I just can't be without it. I first purchased my first bottle about 2 years ago. After I ran out I tried a less expensive hyaluronic bottle. No comparison, not even close. I returned right back to La Roche-Posay and am very pleased with the results, and quality.

Glad I added this to my routine
I added this to my daily skincare routine about 3 months ago. It has definitely improved the overall appearance of my skin. This is a before picture from November and the second one is the beginning of February.

A staple
This hyaluronic acid is a staple in my routine. I use it just about everyday. It helps keep my skin moisturized.
Drugstore that does better than prestige
I am a dry girly and this serum is 10/10 for maintaining a dewy glow. I use both mornkng and night. Paired with citaplast baum also from LRP, best winter skin combo ive ever tried!
I LOVE it
Have repurchased this product about 4 or 5 times now and i love it. I have very dry skin and this does the job
