This is such a TINY bottle but I do think it'll last a good amount of time just because you need so little(the bottle really is tiny for $$$). I LOVE Hyaluronic Acid because it gives my skin instant hydration. I like using this before I use my Foreo Bear because it helps the device glide along my face. I use this whenever I need more moisture to my face. Plus the bottle is so small I can keep it in my purse whenever my skin is feeling parched 😂.
