XERF is an advanced radiofrequency (RF) deep structural skin tightening treatment. It uses two different RF frequencies to treat both the surface and deeper layers of your skin. Lani Laser is one of a few places in the US where you can experience XERF.
The result? Firmer skin. Lifted contours. Smoother texture. A more youthful look.
Can be combined with other treatments for total rejuvenation
Dual frequency technology = deeper, longer-lasting results
Comfort-focused design = less pain than older RF devices
Non-invasive alternative to surgery

XERF goes deeper than other treatments. Because of the monopolar 2 frequencies, XERF is a great treatment for lifting, strengthening and is often called “mini facelift.”
The fibro-septal network is a structure within the skin that supports and connects the different layers.
The constituents of retinacular cutis include collagen, elastin fibers, ligaments, hyaluronic acid, and more. By targeting this network, the treatment helps to enhance the structural integrity of the skin.
Over time, skin can sag due to collagen breakdown, but XERF™ treatments can rebuild collagen to restore firmness.
BEFORE XERF — Light blue staining highlights the collagen distribution in the dermis, hypodermis, fascia, & SMAS layers.
AFTER XERF — Significantly more intense blue staining indicates increased collagen density, or structural changes caused by the treatment.
Most patients describe it as a warm, tolerable sensation. Built-in cooling makes it more comfortable than older RF devices.
Some improvement may be seen after 1 session, but best results usually come after 3–4 treatments spaced a few weeks apart.
Results can last 12–18 months. Maintenance treatments help keep skin firm and collagen strong.
Downtime is minimal. You may have temporary redness or mild swelling, but most patients return to daily life right away.
XERF works well for those with early to moderate sagging, fine lines, or loss of firmness. It is safe for all skin types.
Yes! Many patients combine XERF with lasers, microneedling, or skin boosters for enhanced results. If you have more questions, please ask your provider — we are here to guide you through your XERF journey.
There’s minimal downtime. Most people return to normal activities immediately after treatment, though you’ll want to avoid sun exposure and follow the aftercare guidelines closely.
