Skin Tightening - Inner Arm. Not interested in an arm lift, what options do I have? (Photos)

Question

I had liposuction with Morpheus8 on my upper arms in 2024. Due to aging I am starting to see laxity on the inner aspect of my upper arm. Though I realize there is some excess skin, I'm not interested in a traditional arm lift as I feel, for me, it trades one problem for another. For laxity improvement without liposuction what modalities would be suggested? I see Renuvion, Thermage, BodyTite and perhaps Xerf as options.

Anna Chacon, MD, FAAD · Answer

This is a very reasonable question, and I think your perspective is one I hear often from patients in their 40s–60s: they want improvement in inner-arm laxity, but they are not willing to accept the long scar of a brachioplasty.

The important thing is that you’ve already had liposuction plus Morpheus8, which tells me two things:

Excess fat is probably not the main issue anymore, and
The remaining concern is primarily skin and soft-tissue laxity related to aging and loss of dermal elasticity.

Based on your photos and description, I would think of your laxity as mild to moderate, which is the group where minimally invasive tightening procedures can provide noticeable but not surgical-level improvement.

A quick ranking of the options you mentioned
Best improvement for your situation: BodyTite

If I had to choose one modality with the highest probability of producing a visible improvement in inner-arm laxity without performing a traditional arm lift, I would lean toward BodyTite.

Why?

It uses bipolar radiofrequency delivered both above and below the skin.
It creates controlled heating of the fibroseptal network, which can lead to meaningful skin contraction.
It is generally more powerful than Morpheus8 or Thermage for established arm laxity.

For the inner upper arm, BodyTite is often capable of producing roughly 20–40% tightening, sometimes more in patients with relatively good skin quality and limited excess skin.

The trade-off is that it is minimally invasive (small cannula entry points) rather than completely non-invasive.

Renuvion (J-Plasma)

Renuvion is a little more controversial because results are highly operator-dependent.

Pros:

Can produce excellent tissue contraction in some patients.
Works particularly well when there is residual laxity after liposuction.

Cons:

Outcomes are less predictable as a stand-alone treatment for pure skin laxity.
The best published results are often when it is combined with liposuction, even if only a small amount is performed.

Since you specifically asked about tightening without additional liposuction, I would place Renuvion slightly behind BodyTite for your goals.

Thermage

Thermage is the least invasive option on your list.

Pros:

No incisions
Minimal downtime
Safe for a wide range of skin types

Cons:

The inner arm is one of the more challenging areas for non-invasive RF tightening.
Results are usually subtle and may take 3–6 months to become apparent.
After already having Morpheus8, I would not expect Thermage to provide a dramatically stronger effect.

If your goal is maintenance or a modest improvement, Thermage is reasonable. If your goal is clearly noticeable tightening, I suspect you would find it underwhelming.

XERF

XERF is a newer monopolar radiofrequency platform designed for facial and body tightening.

Early experience suggests:

It can improve skin texture and mild laxity,
with less downtime than invasive RF procedures,
but the amount of contraction is generally more modest than BodyTite.

For someone with very early laxity, XERF could be attractive. For the degree of laxity visible in your photos, I would consider it an intermediate option between Thermage and BodyTite.

One important consideration: you’ve already had Morpheus8

Because Morpheus8 also uses radiofrequency microneedling, repeating another purely superficial RF treatment may give diminishing returns.

That’s why I would focus on a modality that works deeper in the tissue planes rather than simply heating the dermis again.

What I would realistically expect
If you choose BodyTite
Better inner-arm contour
Reduction in the “crepey hanging” appearance
Improved firmness when the arm is held at the side
Some tightening visible even with the arm raised
If you choose Thermage or XERF
Smoother texture
Slightly firmer skin
Less obvious improvement in the amount of hanging skin

Neither non-invasive option is likely to make the arm look like it has undergone a surgical brachioplasty.

My honest ranking for your specific situation

Based on your history of lipo + Morpheus8 and your desire to avoid a scar-producing arm lift:

Modality	Expected Tightening	Invasiveness	My Ranking
BodyTite	Moderate	Minimally invasive	1
Renuvion	Moderate (operator dependent)	Minimally invasive	2
XERF	Mild–moderate	Non-invasive	3
Thermage	Mild	Non-invasive	4
A practical strategy

If this were my patient and she was firmly opposed to brachioplasty, I would usually discuss:

Single-session BodyTite

as the procedure most likely to provide a meaningful visible improvement, and then consider

a maintenance RF treatment (XERF or Thermage)

12–18 months later if additional tightening is desired.

That approach tends to balance effectiveness, downtime, and scar avoidance better than relying on repeated non-invasive treatments alone.

My Bottom Line

For inner upper-arm laxity after prior liposuction and Morpheus8, with no interest in a traditional arm lift and no desire for additional fat removal, BodyTite would be the modality I would expect to offer the strongest tightening effect. Renuvion is a reasonable alternative but is somewhat less predictable as a stand-alone tightening treatment. Thermage and XERF are safer and less invasive, but they are unlikely to produce the degree of improvement that most patients seeking noticeable inner-arm tightening are hoping for.

Your instinct that an arm lift can feel like “trading one problem for another” is completely understandable. In patients with mild to moderate laxity rather than severe hanging skin, I think a minimally invasive radiofrequency-assisted tightening approach is a very reasonable middle ground, as long as expectations are set around improvement rather than complete correction.
