Fullness in the center

Lips look most beautiful when the fullness in the center tapers off at the corners.

Defined “Cupid’s Bow”

The “Cupid’s Bow” of the upper lip is most attractive when it is well-defined and when the two sides look the same.

Side-to-side symmetry

From one side to the other, lips should be symmetrical for a pleasing appearance.

Projection on profile

When viewed from the side, the upper lip should project slightly beyond the lower lip.

Lips-to-eyes relationship

A line drawn upward from the corner of the lips should hit the midpoint of the pupil of the eye.

The Science of Silk

The lips and the lines around the mouth, like other areas of the face, show signs of aging as you get older. This often results in lip thinning, lost shape and an increase in vertical lines above the lip. Restylane Silk is designed specifically to provide natural-looking results in these particular areas by using smaller, smoother particles than those used in other Restylane® products.

In a clinical study of patients treated with Restylane Silk or no treatment, clinical investigators reported:

98% of patients treated with Restylane Silk reported a visible improvement in lip fullness 14 days after injection.

77% of patients treated with Restylane Silk showed at least a one-point improvement in lip fullness (measured on a 5-point scale) eight weeks after treatment.

59% of patients treated with Restylane Silk maintained lip fullness six months after treatment.

As with any other hyaluronic acid gel injected into the lips, the most common side effects are swelling, redness, pain, bruising or tenderness. Please see below for Important Safety Information for Restylane Silk.

Important Safety Information

Indication: Restylane® Silk is indicated for submucosal implantation for lip augmentation and dermal implantation for correction of perioral rhytids in patients over the age of 21.

Restylane Silk contains traces of gram-positive bacterial protein and is contraindicated for patients with allergies to such material or for patients with severe allergies that have required in-hospital treatment. Restylane Silk should not be used by patients with bleeding disorders, with hypersensitivity to amide-type local anesthetics, such as lidocaine, under the age of 22, or by women who are pregnant or breastfeeding. Restylane Silk should not be injected anywhere except the dermis or lip submucosa.

Use of Restylane Silk at the site of skin sores, pimples, rashes, hives, cysts, or infection should be postponed until healing is complete. The most commonly observed side effects are swelling, tenderness, bruising, pain, and redness at the injection site. These are typically mild in severity and resolve in 2-7 days after treatment. Serious but rare side effects include delayed onset infections, recurrence of herpetic eruptions, and superficial necrosis and scarring at the injection site. Do not implant into blood vessels. Use with caution in patients recently treated with anticoagulant or platelet inhibitors to avoid bleeding and bruising.

Treatment volume should be limited to 1.5 mL per lip per treatment and 1.0 mL for perioral rhytid correction, as greater amounts significantly increase moderate and severe injection site reactions. The safety or effectiveness of treatment in areas other than lips and perioral rhytids has not been established in controlled clinical studies.

Restylane Silk is only available through a licensed practitioner. View the complete Instructions for Use.
