However, reports of changes after significant weight loss, particularly through post\u2010bariatric surgery (BaS), are limited. The aim of this 2\u2010year prospective study was to evaluate the prevalence of skin signs and their changes in patients with morbid obesity who underwent BaS. Thirty\u2010one patients were recruited for the study, with a mean age of 38.35 (SD 10.61) years and a male preponderance (male\u2009=\u200919 [61.29%], female\u2009=\u200912 [38.71%]). Patients were scheduled for multiple visits at months 0, 3, 6, 12, 18, and 24 post\u2010BaS. Each subject had a thorough skin examination, biophysical measurements, and laboratory tests at each visit. Striae, acanthosis nigricans (AN), and plantar hyperkeratosis were the most common skin findings (<jats:italic>n<\/jats:italic>\u2009=\u200930 [96.77%], 29 [93.55%], 29 [93.55%], respectively). BaS provided improvements in many skin manifestations, namely striae, AN, acrochordons, plantar hyperkeratosis, hirsutism, lymphedema, pruritus, acne, finger pebbles, and chronic venous insufficiency with varied cumulative rates of improvements. However, acute telogen effluvium was observed in 17 (54.84%) patients. Regarding skin biophysical properties, transepidermal water loss, skin hydration, and pH did not change, while sebum production on the face significantly decreased at months 3 and 6, and elasticity decreased at months 6 and 24. In conclusion, weight reduction by BaS provided improvements in various skin signs, although telogen effluvium was a common
