What is the proper end point for a Jessner Peel?

The proper endpoint for a Jessner Peel is identified as frosting, which is a whitish appearance on the skin's surface during the peeling process. This occurs due to the coagulation of proteins in the skin as a response to the acids in the peel. Frosting indicates that the peel has penetrated adequately into the epidermis, allowing for optimal exfoliation and skin rejuvenation.

Achieving this endpoint is crucial, as it signifies that the treatment is effective and that the peel is working on the intended skin layers. Adequate frosting ensures that the practitioner has performed the peel at the right depth, which contributes to the desired results, such as improved skin texture and tone.

While redness without blisters is a common side effect of chemical peels, it is not indicative of the peel's depth or effectiveness. Complete peeling of the skin and visible irritation might imply an excessive and potentially harmful response to the peel rather than a controlled and effective treatment. Thus, frosting is the key visual cue that indicates the Jessner Peel is working appropriately.
