How the approach is different
The best-known PRX protocol uses the interaction of trichloroacetic acid and hydrogen peroxide in a stabilized professional formulation. WiQo describes the treatment as needle-free biorevitalization with no visible peeling. The goal is a fresher, firmer and more even-looking complexion while preserving the skin’s surface comfort.
Unlike an injectable treatment, the solution is worked topically into the skin by a trained provider. Unlike a traditional resurfacing peel, the expected endpoint is not heavy frosting or sheets of exfoliation.
