Our bodies produce hyaluronic acid (HA), which helps keep our skin hydrated, but as we age, our body loses HA, which causes a loss of volume and unwanted wrinkles, lines, and creases. Restylane-L is a clear gel dermal filler made of hyaluronic acid (HA) which when injected, acts as a lip plumper and wrinkle reducer. RestylaneⓇ can be used to add volume and fullness to the skin to correct moderate to severe facial wrinkles and folds, such as the lines from your nose to the corners of your mouth (nasolabial folds). Restylane may also be used for lip enhancement in patients over 21 years. Restylane-L may also be used to smooth under eye circles or tear troughs.
