THE SAFETY OF FRACTIONAL 1064NM Nd:YAG PICOSECOND LASER IN SKIN REJUVENATION
Main Article Content
Abstract
Introduction: Skin aging is a complex process with many changes in structure and function of the three layers of the skin. This leads to pigmentation disorders, loss of elasticity and smoothness, fine lines and wrinkles on the skin. Treatment modalities include sun protection, topical and oral anti-aging agents, chemical peel, laser and light therapy as well as minimally invasive procedures such as filler, botulinum toxin injection and threadlift. There has been a remarkable increase in the demand for effective and safe with no downtime therapies in skin rejuvenation. In Vietnam, although picosecond lasers are widely used, no studies have been conducted to evaluate the safety of this treatment modality. Materials and Methods: 44 patients were recruited in this longitudinal case series study. A fractional 1064 nm Picosecond laser was used for skin rejuvenation. Results: Typical side effect was transient erythema (68.18% of the patients). Post inflammatory hyperpigmentation was not noticed in all of the subjects. Mild pain was experienced by 61.36% of the patients. There was a statistically significant difference in the side effects between groups of patients having different level of sun exposure. Conclusion: Fractional 1064 nm Picosecond laser is safe in skin rejuvenation for Vietnamese patients.
