I got a pyruvic acid peel about a week ago, immediately after the peel I started getting water boils all over face? (Photos)

When left on the skin to the point of blanching or frosting, pyruvic acid can cause immediate blistering as appears to have happened with you. These are still early days with regard to skin healing post-peel. A skin lightening regimen is generally helpful for persistent post-peel hyperpigmentation. Microneedling or a resurfacing laser may be useful for persistent textural changes. Proceed cautiously, and consult with an expert.
