If you’re booked for XERF in Los Angeles or San Gabriel, what you do in the two weeks before and after your session genuinely affects your result. Energy-based treatments work best on a healthy, well-supported skin barrier and the aftercare protects the collagen you’re paying to build.
Here’s the complete guide: what to do before, what to expect on the day, and how to care for your skin afterward.
A note upfront: the skincare products below are recommendations we find help support barrier health, comfort and recovery. They complement XERF they don’t replace it or change what the treatment does. Your provider will tailor any product plan to your skin at consultation.
What Is XERF?
XERF is a non-surgical dual-frequency radiofrequency treatment from Cynosure Lutronic. It delivers 6.78 MHz to the upper dermis and 2 MHz to deeper tissue, heating the skin to contract existing collagen and stimulate new collagen over the following weeks. Patients use it for jawline definition, lower-face and neck tightening, fine lines and skin firmness.
FDA clearance: XERF received 510(k) clearance in August 2025 (K251327) for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis; tightening effects occur via soft tissue coagulation.
Collagen stimulation works best when your skin barrier is strong going in which is where preparation comes in.
Before XERF: Your Pre-Care Checklist
1–2 weeks before
- Strengthen your barrier. We often recommend SkinCeuticals Triple Lipid Restore 2:4:2 formulated with 2% ceramides, 4% cholesterol and 2% fatty acids that mirror the skin’s natural lipids to support barrier resilience and comfort during treatment. Start it 1–2 weeks ahead.
- Stay out of the sun and skip tanning. Treating recently tanned or sunburned skin raises the risk of irritation.
5–7 days before
- Pause retinoids and exfoliating acids (retinol, tretinoin, glycolic, salicylic). This is the most important pre-care step — treating over actively-exfoliating skin increases sensitivity and the risk of an adverse response.
2 weeks before
- Space out injectables. Schedule XERF at least two weeks after any neurotoxin or filler in the same area (and confirm timing with your provider).
24–48 hours before
- Skip alcohol for 24 hours to reduce swelling.
- Arrive with clean skin — no makeup, lotion, SPF or self-tanner in the treatment area on the day.
- Tell us about cold sores. If you’re prone and we’re treating near the mouth, ask about preventive antiviral medication.
We’ll also take baseline photos insist on this, because you won’t accurately remember your starting point.
On the Day: What to Expect
Your provider applies a conductive gel and glides the handpiece across the treatment area in passes, adjusting depth and intensity by zone. Most face-and-neck sessions run 30–45 minutes. You’ll feel a deep, moving warmth as the cooling cycles; most patients don’t need numbing. Tell your provider if anything becomes genuinely uncomfortable settings should be adjusted, not endured.
After XERF: Repair, Support, Protect
Your skin goes into repair mode immediately. Good aftercare supports recovery and protects your developing result.
The first 24–48 hours
- Expect mild redness or warmth — usually gone within hours, occasionally a day.
- Support recovery. We often recommend SkinCeuticals Advanced RGN-6, which contains peptides and growth-factor technology to support the skin’s natural repair and complement collagen remodeling.
- Be gentle. Bland, non-irritating cleanser and moisturizer only.
- Avoid heat — no saunas, hot yoga, steam rooms or very hot showers for 24–48 hours (heat can add to redness and, over melasma-prone skin, aggravate pigment).
- No makeup for the first several hours if your skin feels sensitive; otherwise makeup is generally fine same-day.
Days 2–5
- Reintroduce actives gradually after 2–3 days, once any sensitivity settles barrier support first, then work back to your routine.
- Support firmness in appearance. SkinCeuticals A.G.E. Interrupter Advanced targets glycation-related aging and supports the appearance of firmer, smoother, denser-looking skin a complement to the tightening happening beneath the surface.
Ongoing — the most important step
- Daily broad-spectrum SPF 30+. Non-negotiable. UV degrades collagen, so sun protection directly protects the result you just invested in. A tinted mineral sunscreen with iron oxides is ideal, especially for deeper skin tones.
- Hydration and protein support collagen synthesis from the inside.
Your Results Timeline
- Immediately: many patients notice subtle tightening (partly a temporary heat-contraction effect)
- 4–6 weeks: new collagen becomes visible; skin begins to feel firmer
- 8–12 weeks: fuller lifting and contour evaluate here, with matched-lighting photos
- 3–6 months: peak result
- 12–18 months: typical window to reassess or schedule maintenance
Who Should Not Have XERF
XERF isn’t right for everyone. Tell your provider if any of these apply some exclude treatment, others change the plan:
Pregnancy or breastfeeding · pacemaker or other implanted electronic device (a specific radiofrequency concern) · metal implants or permanent filler in the treatment area · active infection or open wounds · history of keloid or hypertrophic scarring · autoimmune or connective tissue disease · uncontrolled diabetes or impaired wound healing · recent isotretinoin use · active or unstable melasma in the area. Not exhaustive; assessed at consultation.
And if your real concern is volume loss (filler) or pigmentation (laser), no tightening device is the right tool we’ll tell you at consultation.

Frequently Asked Questions
How should I prepare for XERF?
Start barrier-supporting skincare 1–2 weeks ahead, and pause retinoids and exfoliating acids 5–7 days before this is the key step. Avoid sun and tanning, skip alcohol for 24 hours, schedule at least two weeks after any neurotoxin or filler in the area, and arrive with clean, product-free skin. Your provider will take baseline photos.
Do I need to stop retinol before XERF?
Yes. Pause retinoids and exfoliating acids about 5–7 days before treatment. Using them right up to your session can leave skin more sensitive and raise the risk of irritation from the treatment.
How long is XERF recovery?
Minimal. Most patients have mild redness or warmth that resolves within hours, and return to normal activity the same day. Avoid saunas and hot yoga for 24–48 hours, and reintroduce active skincare after 2–3 days.
What’s the most important aftercare step?
Daily broad-spectrum SPF 30+. UV breaks down collagen, so sun protection directly protects the collagen the treatment builds. It matters more than any single product.
When will I see results?
Some tightening is visible early, though the lasting result comes from new collagen forming over the following weeks. Firmness typically becomes visible around 4–6 weeks and peaks at 3–6 months.
Do I have to use the SkinCeuticals products?
No. They’re recommendations we find help support barrier health, comfort and recovery, they complement XERF but aren’t required, and they don’t change what the treatment itself does. Your provider will tailor any product plan to your skin.
