Can using a lotion with 88% alpha hydroxy on my face safe?

Probably not! It'll most likely cause excessive irritation, pealing, flaking, and redness or even worse, blistering, burning and skin discoloration. At such a high concentration, I doubt you'd be able to leave it on your skin for more than 5 minutes. My question is: why would you want to do that to yourself? Concentrations of 5 to 10% should suffice.
