If you’re looking for effective, non-surgical skin tightening on Long Island, XERF™ is one of the newest and most advanced options available. Now offered at Mandel Dermatology in Greenvale, XERF™ helps lift, firm, and smooth the skin with little to no downtime, making it an ideal treatment for patients across Nassau and Suffolk County.

What is XERF™ Skin Tightening?

XERF™ is an advanced radiofrequency (RF) treatment that works by delivering controlled heat deep into the skin to stimulate collagen and elastin production. This process helps improve skin firmness, reduce fine lines, and restore definition in areas like the face and neck.

Unlike older technologies, XERF™ is designed to maximize results while protecting the surface of the skin, making it safe for all skin types and comfortable for most patients.

Who is XERF™ Best For?

XERF™ is ideal for patients in Nassau and Suffolk County who are looking for:

• Mild to moderate skin tightening without surgery
• Improvement in fine lines and skin texture
• A more defined jawline or tighter appearance in the neck
• A treatment with minimal downtime that fits into a busy schedule

Many patients choose XERF™ as a preventative or maintenance treatment, while others use it to address early signs of aging.

What to Expect at Your Visit
