I am currently using InstaNatural products (https://instanatural.../types?q=Serums) and like them so far... I think.
They have a pretty big selection with all kinds of different ingredients but the 2 biggest ones seem to be the HA serum and then the Retinol based one.
I understand the basics of Retinol and HA but am still unsure which one is actually the better choice for daily appliance and why.
