Conclusion 1. Introduction to Hyaluronic Acid Hyaluronic acid (HA) is a naturally occurring substance in the skin that helps to keep it hydrated and plump. The effectiveness of HA can vary depending on its molecular weight, which is measured in Daltons (Da). Different molecular weights offer unique benefits to the skin. 2. Low Molecular Weight Hyaluronic Acid Low molecular weight HA (LMW-HA), typically ranging from 5 to 200 kDa, has the ability to penetrate deeper into the skin's layers. This allows it to provide hydration from within, which can lead to several benefits: Deep Hydration: Penetrates the dermis layer to hydrat...
