The human skin microbiome, a complex ecosystem of microbes, plays pivotal role in health. This study aimed to investigate the impact two skincare regimens, with preservatives (CSPs) and preservative-free (PFPs), on microbiome correlation quality. double-blind randomized cosmetic studywith split-face design was conducted 26 female participants. Microbial diversity abundance were analyzed using 16S rRNA amplicon sequence data quality utilizing Antera 3D camera. We confirmed earlier studies identification major microbial taxa at genus level, including Cutibacterium acnes, Corynebacterium, Neisseriaceae as predominant part facial microbiome. Furthermore, profile-based subgrouping employed, which revealed that cluster, characterized by family its organism, exhibited significant reduction folds count, fine lines, redness after application PFP compared CSP.

Abstract Delaying aging is an eternal goal for humanity. Acetyl hexapeptide‐8 (AHP‐8) effective skin anti‐aging drug that locally interrupts the signal transmission of muscle contractions and promotes collagen production, thus smoothening wrinkles. However, its high molecular weight strong hydrophilicity limit permeation capacity. To solve this problem, ionic liquid with excellent bioactivity, MAC, synthesized from l ‐malic acid ‐carnitine used as a enhancer to improve effects AHP‐8. The ratio MAC's components optimized based on density functional theory calculations cytotoxicity experiments. Low concentrations MAC significantly increase AHP‐8 transdermal delivery, reaching maximum at 5‐10 wt% MAC. pro‐permeation mechanism investigated using dynamics simulations, penetration enhancement performance are demonstrated by conducting cellular, animal, clinical results show MAC/AHP‐8 outperforms in terms hyaluronic synthesis, anti‐inflammation, anti‐oxidation, inhibition contraction, reducing number area wrinkles increasing moisture elasticity.

However, there is a lack of sufficient evidence substantiate these claims. This paper presents comprehensive review and meta‐analysis evaluate the efficacy safety plants or plant extracts in anti‐aging. Methods Four databases—PubMed, Embase, Web Science, Cochrane Library (CENTRAL)—were systematically searched for articles related interventions aging, covering period from January 2000 December 2024. A total eight randomized controlled trials (RCTs) met inclusion criteria were included meta‐analysis. Results Products demonstrated statistically significant difference improving hydration elasticity, reducing melanin erythema compared other products. No statistical was observed transepidermal water loss (TEWL). Subgroup analysis revealed improvement overall elasticity (R2) during short‐term (≤ 8 weeks)treatments, while no long‐term (> weeks)treatments. Additionally, specific measurements including R5 (net elasticity) R7 (the ratio elastic recovery deformation). Regarding safety, adverse events six studies, remaining two studies did not specify whether occurred.
