Say goodbye to that annoying Double Chin! Li Zhixian, Dean of the Gangnam DayOne Dermatology Research and Healing Center: Achieve a naturally plump jawline in this way.
Say goodbye to your annoying Double Chin! Li Zhixian, Director of the Gangnam DayOne Dermatology Research and Healing Center: A naturally plump jawline can be achieved so easily.
“Why is it that even after losing weight and working out, my side profile still looks plump?” This is probably the most common problem faced by many people in their efforts to achieve a more defined silhouette. A blurred jawline and a noticeable Double Chin not only make one appear fatter but also make them look several years older than their actual age.
This time, we made a special trip to DayOne Dermatology in Gangnam District, Seoul, to interview their founder and director, Dr. Lee Ji-Hyun. This female physician, who has dedicated many years to the field of anti-aging, holds a unique philosophy of “natural regeneration.” In her view, changes in facial contours should not be achieved through forced stretching, but rather through the power of regeneration, allowing the skin to rejuvenate on its own.
Entering Gangnam DayOne Dermatology: A custom-made aesthetic experience that defies the assembly-line model.
The DayOne Dermatology General Hospital is located in a prime location in Seocho-dong, Gangnam-gu, Seoul – on the 4th floor of the Hansung Building at 423 Gangnam-daero. It is easily accessible by walking from Gangnam Station on Line 2 or Sinsa Station on Line 3 of the subway. Unlike those “assembly-line” clinics on Gangnam-daero, where the receptionists are always busier than the doctors, DayOne gives off an impression of professional competence and calmness from the very beginning.
Upon entering the clinic, the simple and bright decor instantly helps one feel relaxed. There is no excessive sales pressure; instead, what greets you is a clean, comfortable environment and friendly service. This place doesn’t have that oppressive feeling of being bombarded with sales pitches as soon as you enter; rather, it resembles a peaceful space where one can seek advice and engage in meaningful conversations about aesthetics.
“Good skin care is not about making everyone’s face look the same. Everyone has different facial contours, bone structures, and levels of aging, so the appropriate treatment plans will naturally vary accordingly.” — Dr. Lee Ji-hyun
President Li Zhixian’s philosophy of anti-aging: It’s not just about treating the symptoms, but also about addressing the root causes.
In the interview, Director Li Zhixian shared her core philosophy: “Many people think that a blurred jawline is caused by being ‘fat’, but that’s not entirely true.” She pointed out that a blurred jawline is often accompanied by three issues: tissue atrophy, thinning of the skin, and a loss of volume. “Simply losing weight may reduce fat, but it won’t address the problem of collagen loss in the dermis.”
For this very reason, Director Li tends to use collagen regenerators such as Aveline (microspheres of poly-L-lactic acid) to address contour issues. “After Aveline is injected into the skin, it stimulates the production of natural Collagen, gradually enhancing the contours step by step,” she explains. She describes this process as a form of “nutritional reinforcement”——“rather than using steel bars and concrete to construct something directly, it’s more like renovating a house to make it stronger on its own.”
- Thermage/HIFU – Thermal energy stimulates the contraction and regeneration of collagen, akin to “strengthening the foundation”.
- Thread Lifting – The physical lifting effect is achieved by implanting threads, which can be likened to “reinforced steel bars providing support”.
- Availan – Injections of microspheres and gradual regeneration can be likened to a process of “nutritional reinforcement.”
Avy岚 Thread Lifting: The science of collagen regeneration
When it comes to the signature treatments at DayOne Dermatology, one cannot fail to mention the “Aveline Mandibular Line Lifting” technique, for which Director Lee Ji-hyun is particularly renowned. Aveline is a new type of collagen regeneration agent whose main component is polylactic acid microspheres (PLLA). After injection, these microspheres stimulate the continuous production of natural Collagen in the body.
Different from traditional Filler treatments, Availan does not simply “fill in the areas that are sunken”; instead, it stimulates collagen regeneration, allowing the loose tissues to “regenerate on their own.” Director Li emphasized: “The results are gradual. Usually, 1 to 3 months after the procedure, you will notice that the contours become more defined, and the skin’s texture becomes smoother and firmer.”
This kind of “natural look” is precisely the effect that Director Lee Ji-hyun strives to achieve. “I don’t like the feeling of instantly getting what people call a ‘internet celebrity face’ after the treatment,” she said with a smile. “What I want is for my clients, half a year later, to be asked by their friends, ‘Did you take some time off recently? You look so good!’ rather than ‘Where did you get that done?’”
Who is suitable for Thread Lifting of the mandibular line with Avril?
Based on the clinical experience of Director Li Zhixian, the following groups of people are particularly suitable for undergoing Thread Lifting of the lower jaw line:
- The jawline is blurred, and the Double Chin is very noticeable—whether this is due to natural factors or the effects of aging.
- The pursuit of natural contours: no obvious signs of filling or a “mask-like” effect is desired.
- Mild to moderate skin laxity – not yet at the point where facelift surgery is necessary
- Desiring long-term anti-aging effects – willing to undergo multiple treatments in order to achieve gradual improvements.
- There are specific requirements regarding the safety of injectable materials – the components of Avilane can be completely absorbed and degraded by the human body.
Of course, Director Li also admitted frankly that Avilane is not a panacea. “If what you are looking for is an immediate result – such as a ‘V-shaped face’ right after the treatment – then Filler or thread lifting might be more suitable options. But if you are willing to give yourself three to six months to allow your facial contours to gradually become more refined, then Avilane would be an excellent choice.”
Postoperative care and precautions
Director Li Zhixian specifically emphasizes that although Avilon injections are relatively safe, it is still necessary to pay attention to the following points after the procedure in order to maximize the effectiveness of the treatment:
- Within 24 hours after the injection: Avoid pressing on the injection site, and refrain from performing facial massages or hot yoga.
- Within one week after the injection – avoid using exfoliating products or irritating skincare treatments.
- Within one month after the injection – avoid excessive sun exposure; it is recommended to use sunscreen with an SPF of 30 or higher.
- Maintain communication – If you experience any abnormal redness, swelling or discomfort after the procedure, please get in touch the clinic immediately.
“Postoperative care is often overlooked, but it is actually a crucial factor in the success of the procedure,” emphasized Director Li. “I recommend that every person considering cosmetic surgery set aside sufficient time for rest and postoperative care before making their decision.”

Conclusion: Changing one’s appearance begins with understanding oneself.
What impressed me most about this interview with Director Li Zhixian was her repeated emphasis on one point: “Anti-aging is not about achieving ‘reverse growth’, but about allowing oneself to age gracefully.” In her view, the root causes of each person’s facial contours are different, and therefore the appropriate solutions also vary. Instead of blindly following trends, it is better to consult a trustworthy professional doctor and discuss one’s own needs and expectations in detail.
