Scarlet SRF Overview

The True and Natural Non-Surgical Facelift

Scarlet RF is a non-surgical skin tightening treatment designed to reduce the appearance of wrinkles and acne scars, in addition to improving skin texture and firmness. This is achieved by utilising fractional microneedle radio frequency (RF) technology to remodel the collagen and elastin in the skin.

The procedure is done in-office, using only topical anesthetic and can be completed in 30 minutes. With virtually no downtime and recovery, you can go back to your life right away as a younger looking you.  


Do You Want Younger Looking Skin? 

Scarlet SRF can:

  • Correct hyperpigmentation

The most ideal candidates have good skin elasticity and mild to moderate skin laxity.

Improvement to skin texture is visible within days, while tightening happens more gradually over 2 to 6 months.


Choosing The Right Provider

Facial enhancement is a technically demanding procedure that requires the highest level of skill. For this reason, it is very important that you choose a provider that is highly skilled and experienced. You should also remember that no single technique is appropriate or “best” for all patients and that facial enhancement should be individualized just for you depending on your goals and facial characteristics. Dr. Fan believes that less is more and will use the simplest, safest, and most reliable procedure to help you look younger.

Dr. Fan is highly experienced with non-invasive and minimally-invasive facial rejuvenation treatments, so he will be able to help you understand the benefits, expected results, risks, and limitations of each type of treatment so that you can decide whether a non-surgical or surgical treatment is best for you.

Scarlet SRF FAQ

What is Scarlet SRF?
SRF is Short pulse Radio Frequency technology TM. Short pulse RF technology is a revolutionary, safe skin treatment with absolutely no down time and no side effects. Developed by the researcher behind the Na Effect, Scarlet SRF is the first RF technology that uses the phenomenon of independent tissue coagulation around each micro-needle electrode with short pulses of alternating bipolar signal energy. The Scarlet SRF is patented not only in America, but in 70 other countries, in Europe, Asia, Middle East, Oceania, and South America.
How does the Scarlet SRF treatment work?
The Scarlet SRF uses micro-needle electrodes bipolar radio frequency (RF) technology to coagulate dermal collagen and elastin fiber in skin. Electrocoagulation helps to rejuvenate existing dermal fibers and produce new collagen and elastin fibers, which improves skin tightening and texture of skin.
What is the NA Effect?

Na effect was first published in Scientific Reports, a journal of the Nature Publishing Group by Dr. Jongju Na. He named this discovery the “Na effect”. Na effect is the key method for the Scarlet SRF, the safest and most effective RF treatment. The distinguishing factor of this phenomenon is the achievement of independent tissue coagulation around each micro-needle electrode.The proven science behind the Na effect is what allows the Scarlet SRF to deliver state-of-the-art care and healing for people of all skin types and issues.

How many treatments are required?
Scarlet SRF treatment delivers results in a single treatment for most patients with little to no downtime. The treatment is very comfortable and attractive to patients. More treatments give more results. We recommend 3-4 treatments during a year to
maximize skin rejuvenation.
How long does a treatment take?
Scarlet SRF treatment takes about 20 minutes for the face and 10 minutes for the neck. The time needed for a body treatment depends on the size and condition of the area to be treated. The Scarlet SRF treatment is both time-efficient and revolutionarily effective.
Is there any special preparation or follow-up regimen?
No. The Scarlet SRF treatment doesn’t need any special preparation or follow-up regimen. Basic skin care and sunscreen is enough for aftercare. Since the Scarlet SRF procedure has little to no downtime, most patients return to their regular activities immediately following treatment. Rosacea patients exhibit a temporary redness or minor swelling after treatment, but this usually goes away within 24 to 72 hours. Scarlet SRF is the safest treatment in the field of RF systems, with little to no down time and no side effects. Clients are good to go immediately after treatment; there is no bleeding or sensitivity as experienced with other microneedle treatments.
How is the Scarlet SRF treatment for different skin types?
Unlike LASER treatments, Scarlet SRF is safe and works on all skin types: I, II, III, IV, V and VI. Scarlet SRF coagulates total dermal layers to rejuvenate total skin without any pigmentation (P.I.H.). Scarlet SRF technology is based on electric
 signals, which doesn’t affect skin color
What does Scarlet SRF treat?

Scarlet SRF targets face skin tightening and lifting, double chin, neck and body skin tightening. Recently, Short pulse Radio Frequency technology TM of the Scarlet SRF was clinically proven to improve rosacea, acne, vulgaris, melasma, and mottled telangiectasia. It is very safe and no rebounded with lower recurrence. And needless to say, the Scarlet SRF improves common issues such as skin texture, pores, photo-aging, scars, and striae.

How does the Scarlet SRF deliver energy into the skin?

The Scarlet SRF uses minimally invasive micro-needle electrode technology, which coagulates the dermis directly with precisely controlled RF energy and varying treatment depth. Treatment depth, power, and mode are adjustable by the user. This procedure delivers the most direct and accurate energy into the skin without any thermal damage on the skin surface.

When do the results appear, and how long do they last?

Visible tightening results come immediately, and the results of dermal remodeling appear over time in the course of new collagen, elastin fibers re-genesis and vascular rejuvenation. For most patients, measurable results appear gradually in 2 to 3 months. The results can last 6 months to a year following a single treatment, depending on your skin condition and aging process.

Is it painful?

No. Most patients report experiencing little to no pain. The Scarlet SRF delivers energy to the skin in a time interval of less than 300 milliseconds (0.3 sec). It is the shortest heating time among all RF devices. The micro-needle electrodes are extremely thin and work with gentle pressure and slow speed technology, developed through numerous clinical trials. Scarlet SRF presents patients with maximum results and maximum comfort.

I did a lot of research before choosing to have a costly elective procedure, and I’m glad I did. Dr. Fan is an exceptional surgeon. He has a remarkable sense of aesthetics. He made suggestions and recommendations I would not have come up with on my own but afterwards saw he’d been absolutely right about. In addition to all of this, he is a genuinely kind person. I have no regrets and if I were going to have anything done in the future I would go back to Dr. Fan."*
