​Jessner's peel is a medium-depth peel containing 14% salicylic acid, 14% lactic acid, and 14% resorcinol. Though considered effective and easy to use, there is little research on this method. We do know this peel becomes stronger as more layers are applied. The amount of resorcinol in this peel makes it more irritating than AHA or BHA peels, and it is generally not recommended for those with dark skin tones due to the risk of resorcinol causing post-inflammatory hyperpigmentation
