Restylane Facial Filler

Restylane is one of the longest-established and most versatile hyaluronic acid (HA) fillers in the world. First introduced in Europe in the mid-1990s and FDA-approved in the United States in 2003, Restylane has decades of clinical data behind it and remains a foundational option for restoring volume, smoothing wrinkles, and refining facial proportions. When injected beneath the skin, Restylane gel integrates into the dermal tissue and binds to water molecules — adding immediate volume while supporting the skin’s natural structure from within. Because the active ingredient is hyaluronic acid, a substance that occurs naturally in the body, Restylane is biocompatible and, importantly, reversible: if a result needs to be adjusted, the product can be dissolved using hyaluronidase. Results typically last 6 to 18 months depending on the specific Restylane formula used and the area treated. Restylane is one of several injectables and fillers offered at Dr. Khosh’s Manhattan practice.

Restylane is a filler where precision and proportion matter as much as the product itself. Dr. Maurice Khosh brings both. 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 earned his medical degree from Albert Einstein College of Medicine, where he was inducted into the Alpha Omega Alpha (AOA) Medical Honor Society. A lifelong student of figure drawing and calligraphy, Dr. Khosh brings an artist’s sensitivity to facial proportion — particularly relevant for Restylane treatments around the lip, smile, and perioral region, where small differences in placement produce visibly different outcomes. With three decades of operating in the same tissues Restylane engages, he combines surgical-level anatomical precision with the trained aesthetic eye required for natural-looking results. Dr. Khosh is a perennial Castle Connolly Top Doctor and a Best Doctors in America honoree.

What Restylane Best Addresses

Restylane is most effective for restoring volume, smoothing wrinkles, and refining proportions across multiple regions of the face. Dr. Khosh uses Restylane to address a range of aesthetic concerns where hyaluronic acid filler is the right choice:

• Lip Enhancement: Restoring fullness, refining shape, and balancing the upper and lower lip proportions
• Vertical Lip Lines and Perioral Wrinkles: Softening the fine lines that develop above and around the lips
• Nasolabial Folds: The “parenthesis” lines that extend from the corners of the nose to the corners of the mouth
• Marionette Lines: The downturning folds from the corners of the mouth toward the chin
• Cheek Volume Restoration: Re-elevating the midface contour with Restylane Lyft or Contour
• Tear Trough and Under-Eye Hollows: Subtle smoothing of the transition between the lower eyelid and cheek
• Chin and Jawline Definition: Refining the lower-face profile with deeper-tissue placement
• Hand Rejuvenation: Restoring volume to the back of the hands using Restylane Lyft

The Restylane Family of Fillers

Each Restylane formulation is engineered with a specific gel consistency and crosslinking pattern designed for a particular tissue depth and aesthetic goal. Dr. Khosh selects the appropriate product based on the area being treated, the patient’s anatomy, and the desired duration of results:

• Restylane (Original Formula): A versatile, mid-weight filler for lips, smile lines, and general facial contouring
• Restylane Lyft: A thicker, more robust filler designed for deeper-tissue volume restoration in the cheeks and hands
• Restylane Silk: A softer, finer formulation designed for lip enhancement and vertical lip lines
• Restylane Defyne: Formulated with XpresHAn Technology to soften deep folds while preserving natural facial movement
• Restylane Refyne: A more flexible formulation for moderate folds with maintained expressiveness
• Restylane Kysse: A lip-specific formula designed for natural feel, movement, and color enhancement
• Restylane Contour: A newer formulation engineered specifically for cheek augmentation and midface lift

“The Restylane family is one of the most versatile filler lines available — different formulations for different tissue depths, different durations, and different anatomical goals. Choosing the right one is half the result. Placing it correctly is the other half.” — Dr. Maurice Khosh
