XERF Skin Tightening Is Everywhere: Here’s How to Care for Your Skin Before and After
Korean aesthetic treatments have increasingly influenced U.S. skincare and aesthetics, and XERF is one of the newest treatments getting attention. As with any professional skin treatment, what you do between appointments matters, too. A thoughtful skincare routine can help keep skin healthy, hydrated and protected before and after the procedure. Let’s take a closer look at XERF skin tightening and how to care for your skin before and after treatment.
What Is XERF?
XERF is a noninvasive radio-frequency (RF) treatment designed to address skin laxity and create a smoother, firmer appearance without needles or significant downtime. While RF has been used in aesthetic treatments for years, XERF takes a different approach by combining two frequencies — 6.78 MHz and 2 MHz — to deliver controlled RF energy at multiple tissue depths.
During treatment, RF energy generates controlled heat beneath the skin's surface. XERF offers multiple depth and intensity settings, allowing providers to customize how that energy is delivered based on the treatment area and individual patient. The system also incorporates surface cooling and real-time temperature monitoring for comfort and epidermal protection.
A 2026 prospective multi-center study evaluating the dual-frequency XERF device for facial laxity found measurable improvements in lower-face lifting and skin laxity following treatment, with no serious adverse events reported.¹
Why Is XERF Suddenly So Popular?
XERF was already gaining momentum in South Korea before making its way into U.S. aesthetic practices. Then came the Kardashian effect. After Kim Kardashian shared XERF as her “new fave” treatment on Instagram, interest in the technology quickly grew.
More broadly, there has been a recent shift towards noninvasive, lower-downtime treatments focused on skin quality rather than dramatic transformation. Earlier this year, Vogue identified XERF as one of the aesthetic technologies to watch within that larger movement.
How to Prepare Your Skin Before XERF
You don’t need a complicated pre-treatment routine. Instead, focus on maintaining healthy, calm, and well-supported skin with these five tips.
Prioritize daily SPF. Protecting against UV exposure should already be foundational to your routine, but be particularly vigilant in the days leading up to your treatment.
Keep skin hydrated. Use a well-formulated moisturizer to support the skin barrier.
Don't overdo actives immediately beforehand. Follow the treating provider's instructions regarding retinoids, exfoliating acids, or other potentially irritating products.
Avoid introducing any brand new products immediately before treatment. This isn't the time to discover that your skin hates a new active ingredient!
Follow your provider's specific pre-treatment protocol. This should always supersede generalized skincare advice!
Supporting Your Results Long After Your Appointment
XERF may be the appointment on your calendar, but your daily skincare routine is what supports your skin the other 364 days of the year. While topical skincare doesn’t replace or enhance the technology behind XERF, a thoughtful routine can support many of the same goals that may have led you to treatment in the first place: hydrated, smooth, firm, healthy-looking skin and a proactive approach to visible signs of aging.
At Full Dose, we believe skincare works best when it’s built around consistency. After your provider gives you the go-ahead to resume your normal routine, consider incorporating ingredients that complement your long-term skin goals:
Peptides: Peptides, including copper peptides, can help support the skin’s natural renewal processes and promote a smoother, firmer, healthier-looking appearance. Full Dose’s Copper Peptide Facial Cream pairs peptide technology with daily hydration, making it an easy addition to a long-term routine.
Antioxidants + Vitamin C: Antioxidant-rich formulas can help defend against environmental stressors while supporting brighter, more even-looking skin. Vitamin C is particularly well-suited to a daytime routine when paired with sunscreen.
Barrier-supporting moisturizers: Keeping skin well hydrated and supporting the skin barrier is important every day, and it can be especially valuable when your skin is recovering from an in-office treatment. Follow your provider’s post-treatment recommendations before introducing or resuming active ingredients.
Retinoids: For longer-term skin renewal, retinoids can help address texture, tone and visible signs of aging. Because they may increase irritation around procedures, follow your provider’s instructions about when to stop and restart retinoids before and after XERF.
Daily SPF: Perhaps the most important step of all: protect your skin every day with broad-spectrum sunscreen. Consistent sun protection helps limit UV-related skin damage and supports the results of the time, care and investment you’re putting into your skin.
The goal isn’t to find a product that makes XERF “work better.” It’s to build a routine that continues caring for your skin long after you leave your appointment. Remember: Healthy-looking skin is as much about what you do consistently as what you do occasionally.
The Bottom Line: Professional Treatments + Consistent Skincare
Professional treatments like XERF can be an exciting part of a skincare plan, but they're only one part of the equation. Consistent sun protection, hydration and evidence-based ingredients help support healthy-looking skin every day, not just when you're leaving the med spa.
