Thank you, Gabby. Thank you to all for joining us today. 2022 proved to be a record year for STRATA. We announced record revenue of $36.2 million, which was above guidance, representing a 20.6% growth compared to the prior year period. Our successes are a direct result of our acute focus on commercial execution and strategic priorities. As a brief recap, this year we achieved record revenues, acquired and successfully commercially launched TheraClear X for acne treatment. Launched XTRAC 1.0 Momentum, a faster laser device than our standard model. Strengthened our leadership team with the addition of John Bagdasarian, Vice President of Professional Relations, and Mike Goodman, Head of International Sales. Entered into new international markets, including Israel and Mexico. Continued to raise awareness of our XTRAC and TheraClear systems at various dermatology conferences.
To achieve this strong double-digit growth, we continued to invest in direct-to-consumer marketing and direct-to-dermatologist marketing, engaged with high volume accounts, refurbished and deployed underutilized assets, interacted with key opinion leaders to fine-tune our messaging, and helped deliver clinical support to our devices. Since September 30th, 2022, we placed 45 XTRAC machines, resulting in a total of 909 systems placed in dermatologists' offices in the United States. This growth signals the demand and need for additional treatment options for psoriasis, eczema, and vitiligo. XTRAC continues to present us with a unique opportunity, as 80% of the users in the United States is for psoriasis. As we have previously mentioned, we have an initiative with our commercial team to drive usage for vitiligo.
We expect the recent approval of the first FDA drug treatment for vitiligo, ruxolitinib cream, more commonly known as Opzelura, could complement XTRAC treatment and drive traffic to dermatologists' offices. In February of this year, we announced the launch of our new XTRAC website. The new website is patient-forward, educational and easy to use. It allows potential patients to find a dermatologist in their surrounding area by using the Practice Finder function. The website emphasizes our focus on broadening patient awareness with the ultimate goal of serving patients who suffer from dermatologic conditions and increasing XTRAC usage. At the beginning of 2022, we announced the acquisition of TheraClear X from Theravant Corporation. TheraClear X is a non-invasive in-office treatment targeting the root cause of mild to moderate acne. In July 2022, we commercially launched TheraClear X.
As part of our launch, we carried out additional market research, built inventory, invested in our sales force, and created a marketing plan. We have utilized the XTRAC sales channels to sell through the TheraClear X system, and we are excited to continue patient and physician education on the TheraClear X device. The cost of TheraClear X to the patient is a fraction of the cost of the competitor device launched this year. As a reminder, 20%-25% of all visits to dermatologists are for acne, often treated with prescription drugs that can be costly. Our device delivers a unique combination of broadband light and vacuum technology that begins to clear the skin rapidly. Our TheraClear X treatment can help potentially increase compliance to prescription acne treatments as patients begin to see results rapidly.
A poster titled Advancement in Personalized Photodynamic Therapy for Rapid Visible Improvement in Patients with Mild to Moderate Acne was presented this January at the ODAC Dermatology, Aesthetic and Surgical Conference. The clinical assessment was conducted by Dr. Gilly Munavalli, MD, Medical Director and Founder of Dermatology, Laser and Vein Specialists of Carolinas in Charlotte, North Carolina, and Dr. Jason Smith and Dr. Taylor Smith of Northwest Georgia Dermatology. The objective of the clinical assessment was to evaluate via photographs, changes in visible acne lesions and skin texture after a series of tailored photopneumatic therapy treatments delivered to patients with mild to moderate acne. Highlights from the clinical assessment included all patients experienced a visible reduction in comedones, pustules, and inflammatory facial lesions. Redness reduction and improvement in skin texture, pore size, and perilesional erythema was observed in the treatments. Most patients responded with two to three treatments.
One adult female patient with persistent perioral acne experienced complete clearance, and adverse events were infrequent and limited to mild erythema, mild bruising, superficial erosions, and temporary changes in pigmentation. These results are encouraging and continue to highlight the efficacy and safety of TheraClear X as a treatment for acne. This February, TheraClear X was demonstrated in the inaugural Winter Clinical Conference. Dr. Joel Cohen, MD, who's a director of AboutSkin Dermatology in Greenwood Village, Colorado, spoke during the live presentation. In Dr. Cohen's practice, he utilizes TheraClear X to build confidence and compliance in patients while waiting for prescription therapy to kick in. The results from the clinical assessment and the demonstration at the Winter Clinical Conference continue to highlight TheraClear X safety and efficacy for treating acne.
With continued exposure in clinic and at industry conferences, as well as exposure to our existing sales channels, we are confident in the potential growth of TheraClear X in 2023. This exposure helps us to broaden the awareness of our device and its proven capabilities. We are excited to see TheraClear X make an impact on revenues this year. Now turning to our international operations. Internationally, we sold 100 systems made up of 88 XTRAC and 12 VTRAC systems. This compares to the 38 systems we sold in 2021. As a reminder, we have signed distribution agreements in Korea, Japan, China, Israel, Saudi Arabia, Kuwait, Oman, Qatar, Bahrain, UAE, Jordan, Iraq, and most recently, Mexico.
This January, we announced an exclusive agreement with MINO Labs, a private company that represents international pharmaceutical companies to commercialize innovative products in Mexico for the distribution of XTRAC, VTRAC, and TheraClear X in Mexico for three years. We look at Mexico's population, it is estimated that 80% of the population is affected by mild to severe acne. We are excited to enter into Mexico's nearly $300 million market as there is a great need for additional treatment options. We look forward to updating the community on our progress in gaining regulatory approval, which we expect to receive in the fourth quarter of this year. In our international markets, there remains a great opportunity to market our TheraClear X system, we expect this to be a focus this year. This year, we welcomed Michael Goodman to STRATA as the Head of International Sales.
We have already seen meaningful improvement in our international operations, specifically noting our increased international sales and STRATA's expansion into Israel and Mexico. I'll now turn the call over to our CFO, Chris Lesovitz. Chris.
Thank you, Bob. Revenues for the fourth quarter of 2022 were $10.6 million, a 17% increase over the fourth quarter of 2021, and a 13% increase over the third quarter of 2022. Our fourth quarter revenue was driven primarily by the continued increase in equipment sales internationally. Recurring revenues in the fourth quarter were $6.5 million, 12% increase over the third quarter of 2022. Similarly, the increase in recurring revenues was driven by the continued increase in XTRAC usage as a result of the increased emphasis on sales force execution.
Equipment revenues for the fourth quarter were $4.1 million, an increase of 72% as compared to the $2.3 million for the fourth quarter of 2021, and an increase of 14% as compared to $3.6 million for the third quarter of 2022. The increase in equipment sales is a result of our increased focus on the international markets. Over the past year, we have made some significant changes. We welcomed Michael E. Goodman as Head of International Sales. We remain flexible in our international product offerings, and we have now have direct distribution agreements with our international partners.
As we discussed last quarter and included in our press release issued this morning, we provided information on a non-GAAP measurement described as gross domestic recurring billings, which represents the amounts invoiced to partner clinics when treatment codes are sold to the physician. It does not include normal GAAP adjustments, which are deferred revenue from prior quarters recorded as revenue in the current quarter, the deferral of revenue from the current quarter recorded as revenue in the future quarters, adjustments for co-pays and other discounts. We also want to provide transparency with respect to the deferred revenue. Since we defer a portion of our GAAP recurring revenue to future quarters, a decrease in deferred revenue can impact each subsequent quarter.
For the fourth quarter of 2022, non-GAAP gross domestic recurring billings was $5.8 million. A decrease of 6% as compared to $6.1 million in the fourth quarter of 2021, and an increase of 4% as compared to the $5.5 million for the third quarter of 2022. Overall gross profit for the fourth quarter was $6.8 million, or 65% of revenues, as compared to $6 million or 66% of revenues for the fourth quarter of 2021. Net loss for the fourth quarter of 2022 was $160,000, or a loss of the half a cent per basic and diluted common share, as compared to net loss for the fourth quarter of 2021 of $849,000, or a loss of $0.02 per basic and diluted common share.
A net loss of the third quarter of 2022 of $995,000, or a loss of $0.03 per basic and diluted common share. Now turning to the results for the full year 2022. Revenues were $36.2 million, a 20.6% increase over 2021. Recurrent revenues in 2022 were $23 million, and equipment revenues for the full year were $13.1 million, a 76% increase over 2021. For the full year of 2022, non-GAAP gross domestic recurring billings were $22.2 million, a 1% increase over full year 2021. Overall gross profit in 2022 was $21.8 million, or 60% of revenues, as compared to $19.9 million, or 66% of revenues for the full year 2021.
Gross profit percentage decrease is attributed to the recording of amortization expense associated with our RA and Theravant acquisitions, in addition to the sales mix during the year between equipment revenue to recurring. Total operating expenses in 2022 was $26.4 million, an increase of 8.9% as compared to $24.3 million for the full year 2021. This increase was driven primarily by our continued execution on our growth initiatives and expanding our business in the United States. We would like to mention that while companies have been facing supply chain issues, we have been able to use parts from our existing machines for repairs. This has allowed us to mitigate delays and maintain a timely process for maintenance on our equipment.
Net loss for the year of 2022 was $5.5 million, or a loss of $0.16 per basic and diluted common share, as compared to net loss for the full year of 2021 of $2.7 million, or a net loss of $0.08 per basic and diluted common share. At December 31st, 2022, cash and cash equivalents was $6.8 million, as compared to $8.8 million as of September 30th, 2022, resulting partially from the payment of $1 million for the acquisition of TheraClear. We are conservatively estimating top line revenue to be in the $38 million-$40 million range for 2023. These estimates reflect our current growth expectations on the business and do not reflect the strategic initiatives we are implementing, which should enhance our business growth during the year.
With that, Bob and I would like to open it up for call for questions.
Thank you. I'll be conducting your question and answer session. If you'd like to be placed in the question queue, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. One moment please while we pull for questions. Our first question today is coming from Jeffrey Cohen from Ladenburg Thalmann. Your line is now live.
Morning, Bob and Chris. How are you?
Good morning, Jeff. How are you?
Great. Congrats on the 21% year-over-year. I guess firstly, can we jump into the guide which kinda appears a little bit on the conservative side, I think 7.7% is the midpoint on the top line. Any thoughts there or commentary? I know that some of this is related to more equipment sales focus.
Yeah, there is a little bit more equipment sales focus, not only internationally, but somewhat in the domestic market as well, Jeff. You know, as we found out last year in, you know, working with some of the Pharos ex-owners, some of them just, they're not interested in getting into the partner model. We've, you know, we've opened it up to potential equipment sales to some of these customers, as well as we've always done, sold into big institutions. That, that's part of it. You know, we took a conservative approach to the guidance, you know, for a number of reasons. There's a lot of initiatives, particularly around international expansion that are relying on regulatory approvals. You know, we have the vitiligo opportunity.
You know, we need to see how that materializes with the approval of Opzelura, how much that drives patients into the doctor's office. We think it's gonna be good. You know, we're optimistic and, you know, we believe that we can increase hopefully, you know, our guidance as the year goes on. You know, coming out of the gate, we want to take a conservative approach to it.
I got it. As far as, ex-U.S. in our estimates, it looks like that growth for 2023 would be five to tenfold off the U.S. growth levels. Is that an accurate assessment?
Can you ask that one more time, Jeff? The question.
On the, on the ex-U.S. growth rate and the ex-U.S. component of your revenues, it looks like.
Yep.
From what we're estimating, that's gonna be multiple times higher as far as growth rate goes.
Going in, into 2023?
Yeah, off that 7.7.
Yeah. We, I mean, yeah, we think it'll still probably be around the same percentage of our overall revenue makeup as 2022. You know, we finished around 35%.
Okay. Got it. Could you talk about alopecia briefly, are you seeing treatments out there that are going on with XTRAC for alopecia specifically?
There is some off-label use. I mean, obviously we can't go out and promote that. That certainly the laser can be used for alopecia successfully. There are a few, I think, small studies out there. You know, something we've thought about, we've done some work around it and looked into potential for getting that indication. It's certainly an opportunity for us.
Got it. Can you talk about any recent trends as far as treatments go and number of cycles, number of sessions, patient compliance and adherence?
Yeah, I mean, you know, I think the big issue that we faced last year with XTRAC was, you know, we talked about a lot and is staffing. It's still been an issue. You know, once you get the patient into the program, they, you know, depending on the severity of the disease, whether it's vitiligo or psoriasis, you know, we think we have a high success rate in getting them through the whole treatment process, you know. For psoriasis, as you know, it's somewhere between 10 and 20 treatments, and for vitiligo, it's generally more than 20 treatments. We do have a coupon program which helps defer some of the costs, so that's been effective. With TheraClear, you know, we're just getting started. We've had a lot of success in getting placements.
We're into the, you know, driving usage with those placements and expanding our footprint even more. We're excited about that opportunity as well.
Okay. Lastly for us, you brought it up. Can you jump into TheraClear and talk about, can you give us a sense of number of placements, regions, typical treatment numbers for patients, and costs?
You know, we finished the year with 2022 with 17 placements. We've had a lot of success in Q1, and obviously we'll be reporting our Q1 numbers here in early May. You know, really saw our big pickup here in the first quarter, and mainly because we've put a lot more of our sales force emphasis behind it. You know, as you know, last year it was a soft launch. We were really trying to gain a lot of information, market research, putting the plans together. It's really started to get traction here in the first quarter. Typical treatments is around five treatments. They start to see results after the first or second treatment, which is great, which makes them come back.
What we're hearing from the dermatology community is the pricing to the patient is kind of across the board, but I'd say on average it's about $250. We've heard as high as $400 in some of the major cities, but on average, it's about $200 to the patient per treatment. Five treatments is $1,000, which is a very reasonable, you know, considering some of the other costs for some of the other devices out there.
Yep. Okay. I think that does it for us. Thanks for taking the questions.
Thanks, Jeff.
Thank you. We've reached the end of our question and answer session. I'd like to turn the floor back over to management for any further or closing comments.
Thanks. Yeah, thank you for joining us today. We've made great progress on multiple fronts in 2022, and we are excited to continue executing throughout this year. Our goal is to help those who suffer from dermatologic conditions, and with the advancements we have made over the past year, we are better equipped to serve them. Thank you again. We look forward to a successful 2023 and catching up in the first quarter.
Thank you. That does conclude today's teleconference and webcast. You may disconnect your line at this time and have a wonderful day. We thank you for your participation.
