"Since my mid-30s, even though I haven't gained weight, my face looks bigger and my cheeks are hollow, so people say I look tired. Even when I diet, my face stays the same. How should I manage this kind of face?"
Why Your Face Still Looks Full Despite Dieting — and Why You Shouldn't Just Fill in Hollow Cheeks in Your 30s
Dr. Hanmi Jung of Heal House Gangnam Branch explains a combined approach for patients in their mid-30s or older who feel their face looks wider while the cheeks appear hollow: reducing the widened contour with The L injections and filling the hollowed front cheeks with Sculptra. The article also covers why treating only one area can throw off facial balance.
[Here is my answer]
After the mid-30s, the face experiences both 'widening' and 'hollowing' at the same time, so addressing only one of the two often fails to achieve balance. You need to reduce the widened contour with The L and fill the hollowed front cheeks with Sculptra to create an impression that looks both smaller and not gaunt.
Hello. I am Hanmi Jung, board-certified dermatologist and lead physician at Heal House Gangnam Branch.
Every time you look in the mirror, you might wonder, 'My weight hasn't changed, so why does my face look so big?' Yet your cheeks are not plump but rather hollow, making you look tired. With both issues occurring together, you may feel uncertain about what to address first.
This is a concern I hear very often in the clinic. However, in many cases, the cause is not body fat but structural changes in the face.
Today, I will explain step by step why this change occurs in the facial shape after the 30s, and why you should consider both the reducing treatment The L and the filling treatment Sculptra together.
Preview: The L and Sculptra
Management principle: After the mid-30s, the face experiences both 'widening' and 'hollowing' at the same time, so it is effective to consider both the reducing treatment The L and the filling treatment Sculptra together.
Role of The L: Reduces the wide and heavy jaw and temple contour through a site-specific design.
Role of Sculptra: Fills the hollowed front cheeks and temple volume by stimulating collagen production.
Timeline for The L changes: Begins after 1–2 weeks, most noticeable around 2–3 months.
Timeline for Sculptra changes: Gradual change; effects become visible after 3 months, with slow filling over 6–7 months.
Treatment design: Usually contour reduction (The L) followed by volume filling (Sculptra), but the emphasis and order are customized 1:1 based on facial balance.
Why does the face in your 30s look bigger even when you diet?
After the mid-30s, unless there is a special case, on one side volume increases in the jaw and temples, making the face look larger with age, while on the other side, the areas that once supported facial definition, such as the front cheeks and temples, gradually hollow out, leading to a hollow-cheeked appearance.
If you only reduce, the hollowed areas become more prominent, making you look gaunt. If you only fill, the wide contour remains, looking heavy. Therefore, you need to reduce the areas that need reduction with The L and fill the hollowed areas with Sculptra to achieve facial balance.
[Key point] After the mid-30s, the face experiences both 'widening' and 'hollowing' at the same time. In this case, if you only reduce or only fill, the facial balance can become awkward, so it is important to address the widened contour and the hollowed volume separately.
What is The L, which reduces the wide and heavy contour?
The L is a signature treatment at Heal House — a facial shape injection that precisely adjusts the lines affecting the size and contour of your face. Rather than reducing indiscriminately, it is a 1:1 customized treatment that designs which areas to reduce and which to preserve. It removes excess volume and preserves essential lines to make the face appear smaller and more slender. Effects begin after 1–2 weeks, settle over 2–4 weeks, and are most noticeable around 2–3 months.
[Key point] The L is a 1:1 customized injection that reduces the wide and heavy jaw and temple contour through a site-specific design. Effects appear over 2–4 weeks and become most noticeable around 3 months.
What is Sculptra, which allows your hollowed front cheeks to naturally fill in?
After reducing the contour, the remaining hollowing in the cheeks is addressed with Sculptra.
Sculptra is not a dermal filler that provides immediate filling; rather, it is a collagen booster that helps your body produce collagen naturally from within. The key ingredient, PLLA (poly-L-lactic acid), stimulates collagen production, enabling your body to create volume on its own.
Sculptra was originally used to correct 'facial lipoatrophy' — the loss of facial fat that causes a hollow appearance. In fact, according to the FDA in the United States, Sculptra was approved in 2004 for the correction of HIV-associated facial lipoatrophy, and later in 2009 it was also approved for the correction of facial wrinkles, including nasolabial folds.
Therefore, Sculptra can be seen not simply as a newly popular volume treatment, but as a PLLA-based collagen booster that has been used medically for a relatively long time. Rather than causing the sunken front cheeks or temples to become overly full all at once, it works in a direction where volume naturally fills in over time, like your original volume. Results gradually appear over 6–7 months, but once established, they typically last about 2 years.
[Key point] Sculptra is a collagen booster that uses PLLA to stimulate collagen production. Rather than immediately filling like a dermal filler, it gradually restores volume to sunken front cheeks and temples starting at 2–3 months, settling naturally over 6–7 months. Although individual results vary, the effect can last about 2 years on average.
How are The L and Sculptra different from each other?
The L is a treatment that 'reduces' broad contours, while Sculptra is a treatment that 'fills' lost volume. Their mechanisms are opposite, so they complement each other.
- The L — Reduction (volume decrease): Targets broad and heavy jaw and temple contours. It reduces areas of excess volume while preserving the lines, with changes beginning at 1–2 weeks and becoming most noticeable around 3 months. Periodic maintenance is needed to sustain the effect, leaving the impression of a smoothly slimmed face.
- Sculptra — Filling (volume): Targets sunken and shadowed front cheeks and temples. It works by inducing collagen to fill in on its own, with changes appearing gradually over 6–7 months and lasting about 2 years on average. It leaves the impression of a face filled like your original volume.
[Key point] The L reduces (jaw and temple contours, noticeable at 3 months, periodic maintenance) and Sculptra fills (front cheek and temple volume, appearing over 6–7 months and lasting about 2 years on average) — they have opposite effects. When appropriately designed together for suitable areas, they can balance the face.
Would The L and Sculptra be effective for me too?
If you fall into the following 4 cases, you may expect benefit from combined reduction and filling management.
- Those whose facial contours appear wide and heavy
- Those who look tired due to volume loss
- Those whose face shape does not refine even with dieting
- Those who want a small yet lively impression without being excessive
[Key point] The L and Sculptra are not simply treatments to reduce or fill the face. They are a combined management that refines wide and heavy contours and naturally restores lost volume, creating a balanced face that looks smaller yet lively.
Are there any precautions or cases where the effect is limited?
Both treatments are non-surgical injection procedures, but there are cases with temporary reactions and limited effects. We explain honestly.
Possible reactions after the procedure
<The L>
- After the procedure, the injection site may appear bumpy, but this subsides within a day and is not noticeable the next day.
- No other specific reactions occur.
<Sculptra>
- Swelling: On the day of the procedure, there may be slight swelling due to the injected solution, but it is not severe enough to affect daily life. The mild swelling is gradually absorbed and disappears over 2–3 days.
- Bruising: May occur temporarily and usually improves within a few days.
- Difference in speed of change: Sculptra requires 6–7 months for collagen to fill in. If you desire rapid change, we recommend a different treatment.
- Please avoid strenuous exercise, alcohol, and saunas on the day of the procedure.
Cases where combined management has limited effect or a different approach is needed
- When the bone structure itself is wide: Injections address muscles and soft tissue, so if the bone is the main cause, the degree of change is limited. In such cases, we will honestly inform you during the consultation.
- When sagging is the main cause: Lifting treatments (such as Ultherapy PRIME®, Soprano Titanium, Alltite, etc.) may take priority over reduction and filling.
At Heal House Gangnam Branch, our principle is that when a diagnosis shows that a combined treatment is not necessary, we recommend only one procedure, or we may recommend no procedure at all.
[Key point] Common reactions to both treatments are temporary swelling and bruising, which usually improve within a few days. If the bone structure is the main cause or sagging is present, the approach may differ. Therefore, whether to undergo the procedure and the treatment plan must be decided after a consultation with a specialist.
Frequently Asked Questions (F&Q)
Q. I'm in my 30s. Should I start managing my face shape already? Changes such as the face appearing wider and cheeks becoming hollow typically begin in the mid-30s. Starting management before significant changes occur can help refine the face more naturally, so many people begin at this age. (Individual results vary.)
Q. Can I receive The L and Sculptra together? Yes, because the two treatments have different mechanisms, they are often designed together. However, the order and interval are adjusted based on the condition of your face, so a consultation with a specialist is necessary.
Q. When will I see results? The L begins to show results after 1–2 weeks and is most noticeable around 3 months. Sculptra appears gradually over 6–7 months.
Q. Which should I get first, and in what proportion? Usually, the design sequence is to first refine broad contours (The L) and then fill sunken areas (Sculptra), but the proportion and order depend on your facial balance.
Q. How is Sculptra different from dermal filler? Dermal filler immediately fills the area, while Sculptra stimulates collagen to fill in on its own, resulting in a more natural and longer-lasting effect.
Q. Are there any side effects? Both treatments may cause temporary swelling or bruising in some individuals, which usually improves within a few days. Whether to undergo the procedure and the treatment plan must be decided after a consultation with a specialist.
