RESULTS ◾ A total of 555 participants were included in the study, of which 210 (37.8%) had baseline BSA levels of 6 –12% (Figure 2) FIGURE 2.

CONLUSIONS ◾ In participants with moderate‑to‑severe psoriasis and a baseline BSA of 6 –12%, HP 0.01%/TAZ 0.045% lotion provided rapid and sustained treatment success, with nearly 45% of participants followed for 1 year not requiring retreatment for ≥1 month REFERENCES 1.
