This article reviews corrective repair methods for unsatisfactory hair transplant outcomes, including strategies for improving recipient and donor sites, but reports no new clinical results.

This article proposes several potential approaches for scar prevention and therapy, including anti-transforming growth factor-β strategies and tissue-engineered skin, but reports no new clinical results.

This article provides a comprehensive overview of tattoo-related issues for clinicians, covering various aspects such as tattoo types, medical relevance, removal methods, complications, and South African legislation, but reports no new research findings.

This scoping review revealed that methods for measuring traumatic scar thickness using ultrasound are inconsistently reported and mainly remain in early research phases, highlighting a need for standardizing these methods to bridge the gap to routine clinical practice.

This discussion reviews common errors in judgment and technique in hair transplantation, outlining potential revisionary surgery options, but it reports no new clinical results.

This study found that using ablative fractional CO₂ laser therapy combined with FUE treatment in patients with post-traumatic eyebrow scars and defects improved follicular survival rates and resulted in well-defined eyebrow shapes.

This review discusses the role of hair follicles in wound healing and scar remodeling, emphasizing that hair follicle transplantation may aid in faster wound closure and scar reduction by enhancing the cellular and molecular mechanisms involved in scarring.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

Pulsed dye laser and hydrogel dressings effectively treat hypertrophic scars.

This expert opinion article presents insights from dermatologists and aesthetic physicians on using polynucleotides (Rejuran®) for skin hydration, rejuvenation, structural support, barrier repair, and scar remodeling, noting their favorable safety profile but highlighting the need for more robust evidence and research.

This study found that royal jelly extract, popular for surgical wound healing, contains stable levels of flavonoids and phenols for up to 28 days.

This chapter provides an overview of terminology for various skin lesions, including primary and secondary types, but does not report new findings or results.

New materials and methods could improve skin healing and reduce scarring.

Endoscopic forehead and brow lifting safely and consistently improves aged eyebrows, but may have complications.

This retrospective study found that a hairline-lowering technique effectively advanced the female hairline by an average of 2.1 cm with high patient satisfaction and minimal complications over 20 years.

This study suggests that fibromodulin may regulate transforming growth factor-β activity during scar formation, influencing the transition from fetal scarless repair to adult scar-forming repair in rats.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.
