The Safety and Efficacy of 1064-nm Picosecond Laser 1064 With Microlens Array for Pore Tightening; a Pilot Study

The objective of this study is to evaluate the safety and efficacy of 1064-nm Picosecond laser 1064 With Microlens Array for Pore tightening.

The Safety and Efficacy of Picosecond laser 1064 Nanometers With Microlens Array for Pore tightening; a Pilot Study Primary outcome : pore size Secondary outcome : side effect, patient satisfaction, global evaluation the patient recieved laser treament once a month for 3 months and then follow up after last treatment at 1, 3 ,6 month

Enlarged facial pores is one of the skin signs in photoaging. There are 3 major clinical causes of enlarged facial pores: highs sebum excretion, decreased elasticity around pores and increased hair follicle volume. Possible causative factors of enlarged facial pores include many exogenous and endogenous factors include genetic predisposition, seborrhea and chronic ultraviolet light exposure. Picosecond laser are new device which has been used in skin rejuvenation. The main mechanism of action is laser induced optical breakdown (LIOB).
