Hyaluronic Acid
Hyaluronic Acid is a natural substance that's widely used in skincare and cosmetic products. It's known for its ability to hold moisture and keep skin hydrated. When you see this on a resume, it usually means the person has experience working with products containing this ingredient or has knowledge about formulating skincare products. Think of it as a super-ingredient that's essential in modern skincare, similar to how Vitamin C or Retinol are key ingredients. In the beauty industry, it might also be called "HA" or "Sodium Hyaluronate" - these all refer to the same basic concept of a hydrating ingredient that's crucial in many beauty products.
