InMode Lifting Effects: Why There's a Difference Between 3 Weeks and 3 Months
- Even with the same equipment, the difference in results between 3 weeks and 3 months is due to collagen timing.
- Immediate lifting is 20%, with the true peak occurring 3 months later during the collagen regeneration phase.
- Adjusting the interval between treatments, rather than a 6-session package, doubles the duration of results.
Information as of July 2026
Collagen Regeneration Timeline
- 20% immediate effect within 72 hours
- 200% peak collagen regeneration in 3 months
- Lasts 6-12 months
Lying on the treatment bed, this is what I was really curious about
"Doctor, when will I see the effects of InMode?" I asked next to the treatment bed, and the answer was, "In 3 weeks." But my friend said, "I thought it was best around 3 months." The same device, the same face, why is the timing so different?
InMode's effects are divided into two stages: 20% immediate lifting and 80% collagen regeneration. The former is completed within 72 hours, and the latter is completed over 3 months. The reason why the timing of experiencing the effects differs for the same procedure is due to this timeline difference.
In this article, I will summarize the duration of InMode effects and the collagen regeneration process based on 3 weeks, 3 months, and 6 months.
- FDA Approved Temperature: 65-75°C in the dermis (critical point for collagen denaturation)
- Immediate Effect: 20% contraction immediately after procedure (thermal coagulation reaction)
- Peak Effect: 200% increase in collagen synthesis after 8-12 weeks (fibroblast activation)
72 hours vs. 3 months: Why do the effects come in two waves?
InMode shoots radiofrequency waves 3-5mm deep into the dermis to create a heat of over 65 degrees Celsius. At this moment, collagen fibers twist like a pretzel and contract immediately, which is the tightening sensation felt right after the procedure.
However, this is actually just a warm-up. The real change begins with collagen regeneration starting after 2 weeks. When the thermally damaged dermis sends a signal saying, "There's not enough collagen here!", fibroblasts start producing new collagen.
A clinical study on InMode FX published in the Journal of the Korean Dermatological Association in 2015 reported that collagen density increased by an average of 68% by week 8 and up to 88% by week 12. This is why you might feel, "Huh? My jawline seems more defined," around 3 months.
Clinical Insight InMode uses a MonoPolar RF (monopolar radiofrequency) method, so heat spreads uniformly deep into the dermis. Compared to Thermage's Capacitive method, the risk of epidermal burns is lower, and dermal targeting is more precise, which was the basis for FDA 510(k) clearance in 2018.
True or False Quiz
The effects of InMode are best immediately after the procedure and gradually decrease thereafter.
Check the answer
False. Immediately after the procedure, only 20% is due to thermal contraction. The real effect, 80%, is completed with collagen regeneration peaking at 8-12 weeks. It's actually a procedure that gets better over time.
So, when is the most beautiful timing?
The peak is between 8-12 weeks. At this time, the newly created collagen pulls the tissue most tightly. This is when you look in the mirror and think, "Wow, my pores look smaller and my jawline is lifted?"
After that, it gradually enters a maintenance phase. Over 80% is maintained until 6 months, and after that, it gradually decreases depending on the aging rate and care. Although there are individual differences, most people consider re-treatment between 6-12 months.
Actually, there's something many people miss here – the timing for home care. Applying Vitamin C serum or peptide cream consistently during the 4-8 week period when collagen is actively being produced increases synthesis efficiency.
| Period | Collagen Change | Perceived Effect | Care Focus |
|---|---|---|---|
| 0-3 days | 20% thermal coagulation contraction | Tightness, slight swelling | Cold compress, avoid irritation |
| 2-4 weeks | Inflammatory response → regeneration signal | Swelling subsides, still subtle | Start hydration & nutrition supply |
| 8-12 weeks | Collagen synthesis peak at 88% | Maximum improvement in jawline & pores | Focus on Vitamin C serum |
| 6 months | Maintenance above 80% | Naturally settled | Consider re-treatment timing |
- Peak Timing: 8-12 weeks post-procedure (high collagen density level)
- Maintenance Period: 6-12 months (depending on individual aging rate & care)
- Re-treatment Interval: Minimum 3 months (wait for completion of collagen regeneration cycle)
InMode FX vs. Forma: The duration of effects also differs
InMode's target depth varies depending on the type of tip. FX primarily targets the dermis at 3-5mm (elasticity, pores), while Forma targets 1-2mm (surface texture).
In a 2019 domestic dermatology clinical study, FX showed a jawline improvement score of 7.2 points (out of 10) at 12 weeks, while Forma scored 5.8. The difference in depth affected the duration of the results.
Therefore, it's common these days to combine both tips for treatment – FX for deep lifting and Forma for surface texture refinement. This approach provides more definite immediate effects and a more pronounced three-dimensionality at the 3-month peak.
6-session package: Do I really need to get all of them?
"Will it last longer if I get 6 sessions?" I've heard this question many times. The answer is interval rather than number of sessions.
Once collagen is stimulated, it goes through a regeneration cycle for 12 weeks. If you stimulate it again before this cycle is complete, the fibroblasts can become fatigued, leading to reduced efficiency. The most ideal interval is 3-4 months.
A presentation at the Korean Society of Aesthetic Medicine in 2020 compared 3 sessions at 3-month intervals vs. 6 sessions at 1-month intervals. The former showed a higher 12-month maintenance rate of 74%. It's not about getting it frequently for longer-lasting results, but respecting the regeneration timing is key.
Tip Some clinics recommend a "6 sessions at 1-month intervals" package, but this protocol is tailored for those who want rapid initial improvement (e.g., those with a wedding or event coming up). If long-term maintenance is your goal, a 3-4 month interval is much more efficient.
If you remember just this, the results will be different
InMode's effects are 20% immediately after the procedure and 80% after 3 months. If you're disappointed by the immediate lifting and stop there, you'll miss out on the real results.
Also, focusing on home care during the peak timing (8-12 weeks) significantly extends the maintenance period. Vitamin C serum, peptide cream, and sufficient hydration – just these three can extend 6 months to 10 months.
- Effect Distribution: Immediate 20% + Collagen Regeneration 80% (3-month peak)
- Optimal Interval: 3-4 months (wait for regeneration cycle completion)
- Home Care Timing: Focus during 4-8 weeks (Vitamin C & Peptides)
- Re-treatment Consideration: 6-12 months (based on 80% maintenance)

Misconceptions
Misconception InMode's effects appear immediately after treatment.
Truth The immediate effect after the procedure is only 20% of the total. The real peak is at 8-12 weeks when collagen regeneration is complete. Judging it as "not effective" early on means missing out on 80% of the results.
Misconception The more frequently you get it, the longer the effects last.
Truth The collagen regeneration cycle is 12 weeks. 3 sessions at 3-4 month intervals were shown to have better maintenance rates than 6 sessions at 1-month intervals, according to 2020 domestic clinical results.
Actions That Ruin InMode Results
- !!Visiting saunas or steam rooms for 3 days immediately after the procedure!! (Aggravates inflammation due to heat stimulation)
- !!Using high-concentration Retinol or AHA products within 2 weeks!! (Damages the skin barrier)
- !!Skipping home care for 4-8 weeks!! (Misses the collagen synthesis timing)
- !!Forcing re-treatment within 3 months!! (Fibroblast fatigue → reduced efficiency)
- Alcohol and smoking are prohibited for 48 hours after the procedure (Delayed regeneration due to vasoconstriction)
Frequently Asked Questions
When can I start seeing the effects of InMode?
Immediate tightening occurs within 72 hours, while significant effects like jawline and pore improvement appear after 8-12 weeks. You might feel it's "not much" at 3 weeks as regeneration is still ongoing.
How long do the effects of InMode last?
The average is 6-12 months. However, with focused home care (Vitamin C & Peptides) during weeks 4-8, it can be extended to 10-14 months. There are individual differences based on aging rates.
Do I need to get it every 3 months continuously?
No. After the first treatment, check the peak at 8-12 weeks, and if it's maintained at 80% after 6 months, then consider re-treatment. Getting it too frequently can actually reduce efficiency.
Which lasts longer, FX or Forma?
FX lasts longer, 6-12 months, while Forma lasts 3-6 months. FX penetrates deeper into the dermis (3-5mm), leading to greater collagen regeneration.
Are there any side effects or risks with InMode?
There is a risk of burns and hyperpigmentation. Especially if the output is excessively increased, it can damage the dermis and even cause a sunken appearance. Cold compresses are essential for 48 hours after the procedure, and thorough sun protection is required for 2 weeks.
What home care should I do to make the effects last longer?
During weeks 4-8, apply Vitamin C serum (over 10%) + peptide cream morning and night. This period is the peak of collagen synthesis, so nutrient supply efficiency is highest.
Lumi's Note
InMode is a procedure that requires patience. If you give up at 3 weeks thinking "it's not much," you'll miss out on the truly beautiful results at 8-12 weeks. Don't be impatient looking in the mirror; instead, try adding a Vitamin C serum during that time. Your skin will let you know when the collagen is filling in.
