Abstract

Background: As you get older, some cells in the body experience a decrease in the amount of production, including hyaluronic acid. Hyaluronan or hyaluronic acid (HA) is a molecule involved in skin moisture. Skin that loses moisture easily becomes dehydrated and signs of aging appear. Moreover, extrinsic factors such as exposure to UV rays and changing weather conditions also affect the condition of the skin and cause damage to the skin's protective layer. Objective: to determine the role and effectiveness of hyaluronic acid for skin rejuvenation. Methods: Literature review with the title “The Role of Hyaluronic Acid for Skin Rejuvenation” is gain by systematic reviewing of some original research article journal and literature review using search engines such as Google Scholar, PubMed, Scopus, and Elsevier. Results: Hyaluronic Acid (HA) has a role in regulating various biological processes such as skin repair, wound healing, anti-inflammatory, tissue regeneration, and immunomodulation. HA filler injection is an effective therapy for skin rejuvenation because it hydrates, removes fine lines and signs of aging on the skin, and is used to shape facial anatomy according to the patient's wishes. Conclusion : Hyaluronic acid is proven to have effectiveness on skin rejuvenation.

Abstract

The Putri Cempo landfill serves as the final disposal site for organic and inorganic waste. Waste from the landfill can dissolve and settle in river sediments, potentially accumulating heavy metals like iron (Fe) and manganese (Mn), which bind easily to organic matter. This study aims to determine the content of Iron (Fe) and Manganese (Mn) in rivers around the Putri Cempo landfill. The concentration of Fe and Mn was analyzed using Atomic Absorption Spectrometry (AAS) referring to SNI 6989.84:2019,   with sediment sampling conducted in rivers around the Putri Cempo landfill. Sediment sampling was conducted in these rivers, revealing Fe levels of 1519.414245 mg/L and Mn levels of 130.033 mg/L. Analysis indicates that Fe concentrations exceed the established quality threshold, while Mn levels remain below it. Heavy metals like Fe and Mn negatively impact abiotic and biotic environments, including human health and agricultural productivity. Elevated heavy metal levels disrupt ecosystem balance and pose health risks, making their management crucial. Reducing heavy metals in river sediments near the landfill is essential. Remediation efforts using bioremediation and phytoremediation technologies can help mitigate these impacts. Ongoing efforts are necessary to control heavy metal contamination in river sediments, ensuring ecosystem stability and public health.
