If you’re interested in Liquid Gold but you’re put off by the price point, The Ordinary does a Glycolic 7% which is a bit more lighter on the exfoliation but will still give very similar results! If that was working for you, you could then invest in the Liquid Gold
… or! If you generally prefer something more hydrating I ABSOLUTELY love the Liquid Gold Rose, it is less exfoliating than both The Ordinary’s equivalent and the Liquid Gold original, but it’s much more hydrating and is all-round more pleasant to use in my opinion. Though it’s still new, so it’s full price, and I can see why you may want to dip your toes in at a lower price point
I personally prefer Alpha-H’s cleansers to Skinstitut’s, though this is because I like my cleansers to be as gentle as possible - plus it makes it easier for me to work out how many actives I’ve got on my face if I skip using them in my cleansers, ha!
