Is It Protected To Use Qwo, The New FDA-Authorized Cellulite Remedy?

What in the event you may eliminate cellulite in a number of months, with no life-style modifications and no invasive procedures? That’s the promise of Qwo, the primary and solely injectable remedy for cellulite authorised by the Meals and Drug Administration.

Qwo was authorised in July 2020 and was first supplied across the nation at dermatologists’ workplaces and medi-spas in late spring 2021. It goals to cut back the looks of cellulite in three rounds of injections, every 21 days aside. And whereas the remedy itself isn’t new, this utilization of it’s. (It was beforehand used to deal with a hand situation that we’ll speak about beneath.)

Whereas some medical doctors really feel it’s a secure, noninvasive remedy choice, others are ready to see its long-term results earlier than leaping on board.

How Qwo Works

Cellulite, dimpled-looking pores and skin the place fats accumulates on the physique, impacts 90% of girls and 10% of males, in response to Scientific American. Cellulite isn’t prompted a lot by the fats itself, however by the strain between muscle tissue and pores and skin that squeezes the fats to the floor.

“Our pores and skin is hooked up to the underlying muscular tissues by tight fibrous bands, and in between the bands is fats,” mentioned Kristen Rezak, a board-certified plastic surgeon at Duke Well being. “Over time, the pores and skin can loosen up or we acquire fats, and that causes dimpling areas as a result of these tight bands don’t stretch, and that’s what causes cellulite. It normally is focused in areas just like the butt and out of doors of the thighs.”

The principle elements in Qwo are two types of collagenase, an enzyme derived from micro organism that breaks down collagen, the primary part of these fibrous bands. As soon as these bands are damaged, the dimples will launch and the pores and skin will look clean once more. Collagenase (beneath the identify Xiaflex) has been utilized in medication for years to deal with Dupuytren’s contracture, a situation that impacts the palms and bends your fingers inward.

“Dupuytren’s is brought on by these fibrous bands that trigger the tip of the finger to bend towards the palm,” mentioned Peter W. Henderson, assistant professor of cosmetic surgery and a breast reconstructive surgeon at Mount Sinai Well being System. “The substance is one thing that’s well-known and is at present being utilized in different initiatives; they’ve simply recognized one other use for it, one with a much bigger market. The fabric is well-known and identified to be secure.”

“In each the Section II and Section III trials, round 60% of sufferers discovered that they had any diploma of enchancment. So, it’s statistically important however not an entire house run.”

– Abigail Waldman, Brigham and Girls’s Hospital

Regardless of collagenase’s good observe document, Qwo nonetheless needed to endure all of the phases of FDA approval for the remedy of cellulite. Whereas it proved considerably efficient in trials, some medical doctors say the change wasn’t dramatic.

“They did Section III research that enrolled over 800 girls, and it confirmed an all proper impact,” mentioned Abigail Waldman, a scientific director of the Mohs and Dermatologic Surgical procedure Middle at Brigham and Girls’s Hospital in Boston.

“The result was measured in whether or not sufferers had been barely happier or a lot happier, principally. In each the Section II and Section III trials, round 60% of sufferers discovered that they had any diploma of enchancment. So, it’s statistically important however not an entire house run.”

Whereas Qwo’s web site doesn’t specify how lengthy outcomes are anticipated to final, a variety of medi-spas providing the remedy declare they need to final a minimal of 1 12 months.

Anaya Aesthetics, primarily based in Pasadena, California, states, “To-date, now we have knowledge to assist longevity for a number of years and can proceed to watch what number of years sufferers can anticipate to see the substantial enchancment.” DC Derm Docs’ web site says, “The FDA- authorised remedy for reasonable to extreme cellulite might final completely. You’ll be able to anticipate your Qwo outcomes at the least one 12 months, however almost definitely, for much longer.”

Is Qwo more practical than different cellulite therapies?

Liposuction and CoolSculpting can scale back fats, however they don’t particularly goal cellulite. Different extra invasive procedures use slicing methods to sever the connective bands. Lasers, radiofrequency, retinol lotions and extra all declare to attenuate cellulite’s look. However how does Qwo examine?

“It’s engaging as a result of it’s a simple, minimally invasive remedy choice for individuals who don’t need a extra invasive process,” mentioned Teo Soleymani, a scientific well being sciences teacher and dermatologic surgeon at UCLA Well being. “There’s comparatively minimal downtime in comparison with different modalities. However, consequently, the outcomes might not be as pronounced or you could not be capable to deal with as massive of an space.”

See beneath for an instance of a before-and-after photograph that Qwo promotes, and also you’ll see the distinction isn’t dramatic:

Henderson cited latest research on Qwo’s outcomes that make it appear promising, however mentioned that for the reason that researchers had been affiliated with the remedy, he’d wish to see extra unbiased proof of its effectiveness over time.

“None of this stuff have been proven to be very efficient,” Henderson mentioned. “We don’t have an amazing scientific resolution for cellulite to this point, so the actual fact now we have seen [Qwo] work in different components of the physique makes this an intriguing risk.”

There’s critical bruising concerned with Qwo.

Qwo’s web site lists its potential unintended effects, which embody injection website bruising, ache, redness, swelling and allergic reactions. A fast Google search will reveal earlier than and after pictures with bruises overlaying a big space, not simply on the injection websites. Ought to that be regarding?

“Collagen additionally composes the liner of blood vessel partitions, so we’re beginning to see bruising could be in depth with Qwo partly as a result of it will probably generally break down the very tiny blood vessels within the pores and skin or subcutaneous tissue. It’s not dangerous, nevertheless it’s visually bothersome,” Soleymani mentioned.

Henderson agreed, saying that whereas the fibrous bands chargeable for cellulite aren’t the one issues made from collagen in that space of the physique, they’ve the very best focus, making them Qwo’s primary goal. Nonetheless, Rezak defined {that a} small proportion of people that expertise extreme bruising might by no means heal.

“The draw back is, when you might have that a lot in depth bruising, nearly all the time it normally simply goes away however it will probably take weeks to a month to appear to be pores and skin once more. A small proportion of individuals can have hemosiderin staining, which stains the pores and skin darkish. That’s not been related to Qwo, however is feasible with in depth bruising,” she mentioned.

Is Qwo secure? What are the long-term results?

Rezak and Waldman each questioned the shortage of variety in Qwo’s Section III trial: all of its contributors had been girls and the bulk had been white, so it’s “exhausting to know if it may be utilized to a extra various inhabitants,” Waldman mentioned.

Qwo has not been accessible lengthy sufficient to know a lot about its long-term results, however some physicians marvel if the physique will deal with it equally to Botox.

“Within the research, nearly everybody developed antibodies to the collagenase, which is smart as a result of it’s a overseas micro organism enzyme,” Waldman mentioned. “I don’t know what the implications for which might be. For different bacterial-derived injections, like Botox, which means sooner or later it doesn’t give you the results you want. I don’t know if the identical idea applies right here, the place in the event you obtained Qwo once more sooner or later possibly it wouldn’t work.”

And whereas the bruising might subside, medical doctors don’t but perceive if there are long-term penalties of collagenase breaking down collagen within the blood vessels or pores and skin across the injection space.

“We don’t actually know what the long-term implications of which might be, which might be what makes me probably the most hesitant about this,” Waldman mentioned. “Because it hasn’t been FDA-approved for lengthy, we don’t know what long-term ramifications are to breaking down collagen in your connective tissue.”

“Clinician experience and having finished this makes a giant distinction. Some persons are extra delicate to this enzyme, so there’s an opportunity for atrophy of the pores and skin. I can see this occurring in unsupervised med spas.”

– Teo Soleymani, UCLA Well being

Till extra is thought about potential issues from Qwo, those that decide to attempt it ought to rigorously contemplate the supply.

“Theoretically, in the event you inject it too shallow or not on the proper angle, you possibly can place this collagenase within the dermis and that may trigger poor outcomes within the pores and skin,” Soleymani mentioned. “That’s the place clinician experience and having finished this makes a giant distinction. Some persons are extra delicate to this enzyme, so there’s an opportunity for atrophy of the pores and skin. I can see this occurring in unsupervised med spas.”

“Sadly, in academia, I cope with quite a lot of issues that come up from these sorts of therapies, like contour deformities and fats necrosis, they usually’re exhausting to deal with. We will’t all the time predict the outcomes of those therapies,” Rezak mentioned.

When you resolve to attempt Qwo, these consultants agree that it is best to discover somebody who can take your medical historical past under consideration and is extremely certified to carry out the injections.

“For all sorts of injectables, I like to recommend getting them from a board-certified dermatologist or board-certified plastic surgeon. Unwanted side effects and issues are uncommon, however you need somebody conversant in the anatomy who can handle issues,” Waldman mentioned.

Most significantly, speak to your Qwo supplier about whether or not the remedy is correct on your physique. Every affected person, and every affected person’s cellulite, is exclusive.

“Sadly, it’s not a magic bullet for all cellulite,” Soleymani mentioned. “The precise affected person choice is essential, as it’s with each beauty remedy. It’s good for individuals who have a number of small downside areas who don’t need to endure greater, extra concerned procedures, however with the understanding that you just’re going to get much less efficient remedy general. When you’re somebody who has quite a lot of dimpling or have already tried physique contouring or laser-assisted cellulite discount, this will likely not work nice for you.”
