Microplasma radio frequency technology using stationary tips on pig skin: A histological study.

Objective: To investigate the histological properties of microplasma radiofrequency (MPRF) using a stationary tip in different treatment strategies on porcine skin.

Methods: Two Bama miniature pigs received MPRF treatment with two types of stationary tips in eight groups of parameters (power, duration, and pass) on dorsal skin. Skin samples were collected from each treatment zone immediately, at 1 week and 1, 3, and 6 months after treatment.

Histological damage characteristics and quantitive analysis of porcine skin with non-insulated microneedle radiofrequency.

Objective: In recent years, the microneedle radiofrequency (MRF) has been widely used for skin rejuvenation, but histological studies on the immediate trauma caused by different parameters of non-insulated RF microneedles METHODS: The skin of three pigs was treated with different needle depths, pulse widths and energy levels of non-insulated microneedle RF. Samples were collected before, immediately, and 2 weeks after treatment. The immediate histological response of each group was assessed and quantified by hematoxylin and eosin staining, Masson staining and Victoria Blue staining.

Utilization of intense pulsed light for hair removal in pediatric auricular reconstruction using tissue expander: A retrospective cohort study.

This study aimed to investigate the safety and efficacy of depilation with intense pulsed light (IPL) in congenital microtia patients during their reconstruction treatment. The hairy skin was treated with the M22TM system (Lumenis, German) using a filter of 695 to 1200 mm. A contact prob with a window of 15 cm × 35 mm or 8 cm × 15 mm was used at a radiant setting of 14 to 15 J/cm2 in the non-expander group and 13 to 14 J/cm2 in the expander group, both in a single pulse mode.

A Rare Symptom of Secondary Infection After Facial Thread Lift and Its Treatment.

Facial esthetics is concerned with the harmonious beauty of the face. The skin, soft tissues, and bone tissues of the face degenerate as people age. Facial thread lift is a new minimally invasive esthetic technique that uses threads embedded within different tissue layers to reposition and support lax tissues.

Comparison of Picosecond and Nanosecond Nd:YAG 1064-nm Lasers in the Treatment of Melasma: A Split-Face Randomized Clinical Trial.

Background: Melasma is a refractory pigmentary disorder. The picosecond Nd:YAG 1064-nm laser (PSNY) has promise as a better treatment for melasma with few side effects and favorable therapeutic efficacy. The authors evaluated the efficacy and safety of PSNY and the nanosecond Q-switched Nd:YAG 1064-nm laser (QSNY) in patients with melasma.

Evaluation of the safety and efficacy of a fractional picosecond 1064 nm laser for post-acne erythema in adult Chinese patients.

Objective: To evaluate the efficacy and safety of fractional 1064 nm picosecond Nd:YAG laser (FPNYL) in the treatment of post-acne erythema (PAE) of adult Chinese.

Materials And Methods: A total of 22 patients received 1 session of treatment and were followed up at the eighth week. Primary outcomes were measured by the Clinician erythema assessment scale (CEAS).

Occupational health and safety: measurement and analysis of the electromagnetic radiation produced by radiofrequency devices for rejuvenation.

With the ongoing development of cosmetic technology, many different types of radiofrequency (RF) devices are widely used for face and body rejuvenation. These, like many other high-power devices, may emit excessive electromagnetic radiation into the surrounding environment. Long-term exposure to this environment can lead to poor health outcomes; therefore, it is important to measure and analyze the electromagnetic radiation levels for the health and safety of therapists.

Optical characteristics of the skin with dark circles using pump-probe imaging.

Pump-probe imaging was first used for quantitative analysis of melanin in dark circles' skin to improve the ability to diagnose and treat dark circles on human skin. This study aimed to compare the distribution characteristics in melanin of lower eyelid skin tissues and to determine whether pump-probe imaging has potential for the classification of dark circles in vivo. Specimens obtained from 15 patients undergoing blepharoplasty were examined using pump-probe imaging.

Treatment of exogenous hyperpigmentary disorders following silver ion-related chemical exposure with 1,064nm Q-switched laser: a 10-year follow-up.

1,064 nm Q-switched laser has been commonly used to treat pigmentation. However, there is still a lack of research on the treatment of hyperpigmentation caused by topical exposure to metallic salts-related chemical oxidation. We reported an Asian female patient who developed pigmentation 1 year on the face and neck after the recovery from a chemical explosion injury.

Quantitative analysis of collagen after intense pulsed light and erbium-doped yttrium aluminum garnet laser treatment on rabbit skin.

Objective: To investigate the effects of intense pulsed light (IPL) and ablative 2.940 nm erbium-doped yttrium aluminum garnet (Er: YAG) laser on dynamic changes in collagen by quantitative analysis of type I collagen (Col I) and type III collagen (Col III), transforming growth factor (TGF), and matrix metalloproteinases (MMPs) in the dermis of rabbits.

Methods: Backs of ten rabbits were divided into four treatment areas: IPL normal energy group, IPL high-energy group, erbium laser normal energy group, and erbium laser high-energy group.

Subcutaneous tissue necrosis with fat liquefaction, hematoma, inflammatory mass after microwave-based treatment for axillary hyperhidrosis.

Axillary hyperhidrosis (AH) and bromhidrosis are common complaints in Asians for consultation in dermatology. A microwave-based device has gradually become a first option option during this decade because of the safety and efficacy both for AH and osmidrosis. Other complications reported are transient median and ulnar neuropathy and brachial plexus injury with sensory and motor dysfunction.

[Correction of prominent malar complex by L-type osteotomy].

Objective: To present a new method for correction of prominent malar complex by L-shaped osteotomy through an intraoral incision.

Methods: Based on the anatomical characteristics of the malar complex, we designed a new L-shaped osteotomy for malar eminence reduction. The procedure includes oblique incision of the upper part of the mala, vertical incision of the anterior part of the mala and "greenstick" fracture of the zygomatic arches.
