What are they?
Soft tissue fillers are substances injected into the skin to create a more youthful appearance. Many fillers are available but the most popular fillers are made from hyaluronic acid, a clear gel that is hydrophylic, allowing it to correct wrinkles and volume deficits by drawing in water. Hyaluronic acid is a substance which naturally occurs in our skins, keeping it firm and hydrated. Fillers made from hyaluronic acid are very similar in structure but are cross-linked to allow them to last for longer in tissue before our bodies break them down.
Different thickness gels (fillers) are used in different areas, according to the condition being treated.
