I am unable to get my hands on a Jessners peel in either reasonable time or at a reasonable price. However, I know that applying the Jessners peel before a TCA peel makes the TCA peel go deeper and provide better results. Is there another type of acid such as glycolic, lactic, ascorbic acid, etc. put on before a TCA peel that will give a similar effect to TCA plus Jessners?
If there isn't, wouldn't just adding more layers of TCA give me a similar good frosting compared with Jessners and TCA? Doesn't the level of frosting tell you how deep the peel has gone whether it's TCA alone or TCA combined with another acid?
