[Miscellaneous] Are acids like AHA and BHA more effective in a higher concentration used less often (such as a weekly peel) or are they more effective used daily?

Beauty Tips For Body Care
I was looking at the Ordinary's Website catalogue last night and I saw both the AHA 30% + BHA 2% Peel for weekly usage as well as the Glycolic 7% Toner for daily usage, and it made me curious which usage and concentration makes acids more effective. Like which is better? Is one better for certain skin concerns over others?
