The difference between various brands of acids?

[WellTidy]

I saw this super cheap boots own brand hyaluronic acid today. I use hyaluronic acid, half way through a Dr Sebagh 20ml bottle of it at the moment, which is considerably more expensive!

Does anyone know what the difference is between the two, or between the brands of acids, please? Wondering if I can save myself quite a bit!

Yeah I think with hyaluronic acid there probably isn't much difference? I am using the Hada Labo premium HA and its about £15 for 170ml! There is a bit of difference in texture eg some people don't like The Ordinary HA as they say it's too gloopy. But I don't think it's necessary to pay more.

Same with glycolic acid. I use the ordinary glycolic acid toner and it's just as good as the Pixi Glow.
