| AE type | AEs this study (n = 301) HPDR 3 passes, 35% power |
AEs, Holcomb et al13 (n = 55) HPDR 1 pass, 20% power |
AEs, Weniger et al23 (n = 472) Erbium-YAG laser deep resurfacing |
|---|---|---|---|
| Acne/milia | 1 | 5+ | Unknown |
| Hyperpigmentation | 3 | 8 | Unknown |
| Hypertrophic scarring | 1 | 2 | 7a |
| Hypopigmentation | 0 | 0 | 6a |
| Prolonged erythema | 10 | 0 | 70a |
| Slow healing | 1 | 4 | Unknown |
AEs observed in this study compared with similar AEs in two recent facial skin resurfacing studies including HPDR (lower energy, single pass treatment; Holcomb et al) and dual mode erbium YAG laser skin resurfacing (Weniger et al23).
aNumber of patients determined based on percentage observed and total patients treated. AE, adverse event; HPDR, helium plasma dermal resurfacing.
