When Will the Xerf Effect Change? Summary of Changes After 6 Months Post-Treatment
2026-08-18
Xerf is a lifting treatment that induces skin elasticity and collagen changes using radiofrequency energy.
Changes begin to appear immediately after the treatment, and the effects gradually accumulate over time.
The timing of when effects are felt can vary depending on skin condition, number of shots, and treatment area.
Hello, this is Derna Clinic.
Xerf is a lifting treatment often mentioned alongside Thermage and Ultherapy, gaining interest as it is known to be used by famous actors and international influencers. More people are looking into Xerf, hoping for skin elasticity and a natural lifting effect.
However, when you start to learn about Xerf, one question arises: "It’s said to be a famous lifting treatment, but when will the Xerf effect appear?" In fact, if you look for reviews, some people report feeling changes immediately after the treatment, while others notice effects only after several months. What could be the reason for the different timings of perceived effects, even though it’s the same Xerf treatment?
Today, I will explain in detail when the Xerf effect appears, in what order it manifests, and why the timing of perception varies from person to person.
When Will the Xerf Effect Appear? Reasons It Doesn't Complete All at Once
Xerf uses two types of radiofrequency (RF) at 6.78MHz and 2MHz to deliver heat energy from the dermis to the fascia layer. At this time, two different reactions occur at different points in the skin.
1️⃣ Immediate Contraction of Collagen Due to Heat
Collagen fibers exposed to heat temporarily change structure and exhibit a tightening response at that moment. Some people feel a tightening sensation as if the skin is being pulled right after the treatment, which is due to this reaction.
However, the changes at this point are closer to the result of the existing collagen reacting to heat, and they may naturally subside over time.
2️⃣ New Collagen Production
The skin that has received heat stimulation increases the activity of fibroblasts during the recovery process and begins to produce new collagen. This process does not complete immediately after the treatment but progresses gradually over weeks to months.
Therefore, it is better to understand that the Xerf effect does not appear all at once but rather as a sequential process of immediate tightening response followed by subsequent collagen changes.

When Does the Xerf Effect Start? Change Process from Immediately After Treatment to 6 Months
When will the Xerf effect start? The timing can be viewed in the following flow:
🟡Immediately After Treatment to 1 Week
Due to the immediate contraction response of collagen fibers, some people feel a tightening sensation in their skin right after the treatment. However, this is closer to a temporary contraction response of the existing collagen. Therefore, it is better to observe the changes that appear later rather than thinking that the final Xerf effect has been completed from the beginning.
🟡1 to 3 Months
During this period, as fibroblasts become activated, new collagen is produced, and gradual changes begin to appear in the skin. Therefore, some people may feel more distinct changes in skin elasticity or contour as time passes compared to immediately after the treatment.
🟡3 to 6 Months
As time passes, collagen remodeling occurs, and the changes that began earlier accumulate. By the 6-month mark, you can expect results close to the final tightening effect, and afterward, the effects may gradually decrease as the natural aging process resumes.
The Xerf effect is known to last approximately 6 months to 1 year, but the actual duration and degree of perception can vary depending on individual skin condition, degree of aging, treatment area, etc.
Three Reasons Why the Timing of the Xerf Effect Differs Among Individuals
Even with the same Xerf treatment, some people feel changes quickly, while others only perceive effects after several months. The following differences can be considered as representative reasons.
1️⃣ Number of Shots and Treatment Area
In cases where specific problem areas are managed intensively, such as with 300 shots of Xerf, compared to treating the entire face with 600 shots, the range of energy delivered can differ. Therefore, the points at which changes are felt can also vary depending on the treatment area and scope.
2️⃣ Skin Thickness and Fat Amount
The thickness of the skin and the amount of fat also vary among individuals. The way energy is delivered and how collagen reacts can differ depending on whether there is a certain amount of fat under the skin or if there is less fat, which can affect the speed at which effects are felt.
3️⃣ Degree of Aging Progression
The degree of perceived changes can differ even with the same treatment, depending on whether skin sagging has just begun or has already progressed significantly. Ultimately, when the Xerf effect appears and how distinctly it is felt can vary based on individual skin conditions.
Therefore, rather than simply judging the timing of effects based on others' reviews, it is important to determine the number of shots and treatment area that suit your current skin condition through consultation.
To Maintain the Xerf Effect, Proper Care is Important
After the Xerf treatment, the skin may temporarily become sensitive, so it is important to minimize irritation and protect the skin barrier. Please pay attention to the following points after the treatment.
✅Cleansing and Makeup: Cleansing can be done from the day of treatment, but please manage your skin gently without scrubbing hard.
✅Sunscreen: Apply a sunscreen with SPF 30 or higher thoroughly when going outside.
✅Moisturizing Care: Since dryness may be temporarily felt, please use sufficient moisture and regeneration creams to protect the skin barrier.
✅High-Temperature Environments and Irritation: Avoid saunas, jjimjilbangs, intense exercise, drinking, and smoking for at least a week.
Additionally, to maintain the Xerf effect long-term, you may consider regular maintenance every 6 months to 1 year based on your skin condition.
Frequently Asked Questions
Q. What is the average price range for Xerf lifting (cost of 300 shots vs 600 shots)?
The price range for Xerf differs between focusing on specific problem areas with 300 shots and caring for the entire face with 600 shots. Additionally, there may be differences based on the equipment settings and consultation/diagnosis systems of each clinic, so it is best to receive accurate pricing information after assessing your skin condition during a consultation.

Why did actress Ko So-young choose Xerf before her broadcast?
Actress Ko So-young mentioned on her YouTube channel that she received 600 shots of Xerf before her broadcast shoot. She particularly noted, "It’s a radiofrequency-based laser that makes you look lively without being obvious and provides noticeable lifting." The fact that it can be comfortably received without anesthesia, while providing immediate tightening and a natural glow, seems to be why it has become a topic among celebrities.
Can I receive LDM, skin boosters like Rejuran or Juvelook, and Botox after the Xerf treatment?
Radiofrequency treatments are often performed alongside injectable treatments like skin boosters or Botox, but the order and intervals can vary depending on the treatment area and individual skin condition. Generally, it is recommended to perform Xerf first and then follow with injectable treatments, as heat stimulation can affect the filler/injection areas. Please confirm the exact order and intervals during a consultation.
Does Xerf work on areas other than the face, such as double chin sagging or deep neck wrinkles?
Xerf uses dual radiofrequency at 6.78MHz and 2MHz to deliver energy from the dermis to deeper layers, so it can be applied to areas of concern like double chin lines or neck wrinkles. However, since the thickness of the skin and degree of sagging differ by area, it is important to adjust the energy intensity and treatment range according to the desired area.
If I am in my late 20s to early 30s, will getting Xerf too early cause resistance or burden on my skin?
Xerf is not a treatment that uses drugs but rather a physical method that stimulates collagen with heat energy, so receiving repeated treatments does not create resistance in the same way that drug tolerance does. In fact, starting management in your 20s or 30s, before sagging becomes significant, can be a preventive approach to slow down collagen loss. However, it is advisable to adjust the treatment cycle and intensity according to your skin condition.
I have a relatively thin face; will there be a risk of sagging or a peanut-shaped face after the treatment?
Xerf does not break down or burn fat but induces collagen contraction and regeneration with heat energy, so the risk of sagging due to fat loss is relatively low. However, individuals with thinner skin or less fat should carefully adjust the treatment intensity and energy settings for each area.
Will there be redness, swelling, or marks immediately after the treatment? Can I apply makeup right away?
Xerf is a non-invasive method that is performed without damaging the epidermis, so light cleansing and makeup can be done from the day of treatment. Some individuals may experience temporary redness, slight swelling, or warmth after the treatment, but these usually subside naturally within a few hours, allowing for a return to daily activities or work without significant issues.
If I recently received Ultherapy or Thermage, is it okay to get Xerf additionally?
If you have recently received other energy-based treatments like Ultherapy or Thermage, it is safe to perform Xerf after allowing sufficient recovery time for the skin. Since these treatments stimulate the skin in different depths and ways, it is advisable to determine appropriate intervals through consultation, considering the previous treatment areas and intensity.
Can I use a home radiofrequency massager or beauty device after the treatment?
Immediately after the treatment, the heat and stimulation remaining in the skin may not have settled yet, so it is recommended to wait at least 1 to 2 weeks before starting to use home radiofrequency devices or massage devices.
The Xerf effect can appear gradually, from the immediate tightening after treatment to collagen remodeling over several months. Therefore, rather than judging the timing of effects based solely on others' reviews, it is important to check the changes according to your skin condition and treatment area.
