Restylane Silk

The lips are one of the most expressive features of the face — and one of the most technically challenging to treat with filler. The skin is thin, the underlying tissue is constantly in motion during speech and smile, and small differences in volume or placement produce visibly different results. Restylane Silk is engineered specifically for this region. As a member of the Restylane family of hyaluronic acid (HA) fillers, Silk uses smaller, smoother gel particles than other Restylane formulations — designed for gentle, natural-feeling lip enhancement and for softening the fine vertical wrinkles that develop around the mouth with age. FDA-approved for lip augmentation in adults 21 and older, Restylane Silk can subtly restore lost lip volume, refine the natural lip border, and smooth perioral lines — producing results that look like the patient, only more rested and refined. Restylane Silk is one of several formulations within the Restylane family, all offered as part of the broader injectables and fillers options at Dr. Khosh’s Manhattan practice.

Lip filler is one of the most challenging applications of any injectable — and few facial plastic surgeons bring the depth of published lip expertise that Dr. Maurice Khosh offers. Dual board-certified by the American Board of Facial Plastic and Reconstructive Surgery and the American Board of Otolaryngology–Head and Neck Surgery, Dr. Khosh is a Fellow of the American College of Surgeons (FACS) and a Clinical Assistant Professor at Columbia University. He authored “Lip Reconstruction” — a published chapter through McGraw Hill on the surgical anatomy and aesthetic principles of the lip and perioral region — work that directly informs his approach to filler placement in these tissues. With three decades of operating on the lip and perioral region across both surgical and non-surgical applications, Dr. Khosh brings the kind of anatomical precision required for a product engineered specifically for the lips. He is a perennial Castle Connolly Top Doctor and a Best Doctors in America honoree.

What Restylane Silk Best Addresses

Restylane Silk is most effective for subtle lip refinement and the fine lines that develop around the mouth with age. Dr. Khosh uses Silk to address a range of concerns specific to this region:

• Lip Augmentation: Restoring lost lip volume with a soft, natural feel that preserves lip mobility
• Lip Border Definition: Refining the vermillion border (the line where the colored lip meets the surrounding skin) for a more defined lip shape
• Vertical Lip Lines (Lipstick Lines): Softening the fine vertical wrinkles that develop above the upper lip
• Cupid’s Bow Definition: Subtle refinement of the natural peaks of the upper lip
• Subtle Lip Asymmetry: Balancing minor differences between the upper and lower lip
• Naturally Thin Lips: Adding gentle, age-appropriate volume to lips that have always been thin

How Restylane Silk Compares to Other Lip Fillers

Restylane Silk is one of several hyaluronic acid fillers used for lip enhancement, and each option has slightly different characteristics. Silk’s smaller particle size and smoother gel consistency make it especially well-suited for surface-level refinement and fine perioral lines — areas where heavier fillers can produce visible lumps or an overcorrected appearance. Other lip-targeted HA fillers, such as Juvederm Volbella XC and Restylane Kysse, offer different feel and durability profiles. During consultation, Dr. Khosh evaluates the patient’s lip anatomy, desired result, and tolerance for maintenance to determine which product best matches their goals. Results from Restylane Silk typically last about six months — lips have more movement than other facial areas, which gradually breaks down filler more quickly than in static regions. Like all hyaluronic acid fillers, Silk can be dissolved with hyaluronidase if the result needs to be adjusted.

“Lip filler is one of the most visible places where overcorrection becomes obvious. The goal with Silk — and with any lip filler — is to refine without changing who the patient looks like. The lip should still look like their lip, not someone else’s.” — Dr. Maurice Khosh
