Retinoids remain the most extensively studied topical agents for skin aging. Meta-analysis of 24 randomized controlled trials confirms that topical retinol at concentrations of 0. 025-1% significantly improves fine lines, skin texture, and pigmentation.
Retinoids remain the most extensively studied topical agents for skin aging. Meta-analysis of 24 randomized controlled trials confirms that topical retinol at concentrations of 0.025-1% significantly improves fine lines, skin texture, and pigmentation. Tretinoin shows superior efficacy but higher irritation rates. Retinol requires conversion to retinoic acid in the skin, with 1% retinol achieving similar outcomes to 0.025% tretinoin after 24 weeks. Progressive introduction protocols reduce purging and irritation by 73%.
Original source →This study evaluated the safety and effectiveness of HYDRAGEL A2, an injectable medical device containing hyaluronic acid (HA), polynucleotides (PN), and niacinamide, for improving facial skin quality. These ingredients are increasingly recognized for their synergistic effects in aesthetic medicine, with HA and PN providing hydration and skin support, and niacinamide offering anti-inflammatory and antioxidant properties. A prospective, open-label clinical investigation was conducted on 42 female subjects (mean age 45 ± 1 years, Fitzpatrick skin phototypes II-V) to assess skin elasticity, hydration, and mild skin depression correction following cheek area injections.
To evaluate the clinical efficacy of device-free auricular acupressure for rosacea and verify its neuroimmunomodulatory effects using serum biomarkers and immediate vascular imaging in a sham-controlled trial. DESIGN, SETTING, AND PARTICIPANTS: This single-center, randomized, sham-controlled, assessor-masked trial was conducted in the Dermatology Outpatient Department of the Second Affiliated Hospital of Xi'an Jiaotong University from October 2025 to May 2026 and included 204 patients with rosacea who were receiving standard first-line treatment. Participants were assigned in a 1:1 ratio using block randomization.
Dyspigmentation and photodamage are common concerns in patients who seek aesthetic consultation. A number of treatment modalities have been utilized to address this issue. 1927 nm thulium fiber laser is a fractionated non-ablative laser that has been shown to be safe and effective in treatment of photoaging.
