Restylane® is indicated for treatment of moderate to severe facial wrinkles and folds, such as nasolabial folds. After your treatment, you might have some redness or swelling. This will normally last less than seven days. Avoid excessive sun and UV lamp exposure, and extreme cold weather until any redness or swelling disappear. If you are pregnant, breastfeeding, have severe allergies, or under 18, you shouldn’t use Restylane.®
