Efficacy and Safety of Fractional 1064-nm Picosecond Laser for Facial Skin Tightening

Efficacy and Safety of Fractional 1064-nm Picosecond Laser for Facial Skin Tightening

The goal of this clinical trial is to learn the efficacy and safety of fractional 1064-nm picosecond laser for facial skin tightening. The main questions it aims to answer are:

• Efficacy of fractional 1064-nm picosecond laser for facial skin efficacy including the changes in wrinkle, nasolabial fold, skin laxity, and skin elasticity
• The changes in texture and pore volume using Antera
• The changes in bioengineering assessment: melanin index, erythema index, sebum level
• Adverse events Participants will be treated with 3 sessions of fractional 1064-nm picosecond laser (full face 4 passes, vector lines 4 passes), spaced 4 weeks apart. Follow-up visits 1, 3, and 6 months after the last treatments.

The efficacy and safety of fractional 1064-nm picosecond laser for facial skin tightening in participants aged 40 to 55 years, BMI < 25 kg/m2, and have mild to moderate facial laxity.

Inclusion Criteria:

• Aged 40-55 years
• BMI < 25 kg/m2
• Asian
• Mild to moderate facial skin laxity using quantitative grading scale (grade 1.5-2.5)

Exclusion Criteria:

• Pregnant or lactation
• Subjects who have been treated with any kind of energy-based device 6 months prior to the inclusion
• Subjects who have been injected with botulinum toxin, filler, or platelet-rich plasma on their faces 6 months prior to the inclusion
