When will I feel the effects of The L?

From 1 to 2 weeks after the procedure, the lines gradually become refined, and at around 3 months, unnecessary facial bulk is trimmed, allowing you to see the most distinct and satisfying results.

How much pain is there during The L procedure?

Because The L uses a very fine needle to inject small amounts in divided doses, pain is generally not severe, and we apply anesthetic cream to reduce discomfort.

Is there any downtime, such as swelling or bruising, after The L procedure?

Due to the nature of injection procedures, minor bruising may occur with The L, but it usually fades within a few days. Most people have no disruption to daily life, but recovery speed varies by individual, so if you have an important schedule, it is advisable to book with some leeway.

How long do the effects of The L last?

With maintenance treatments every 3–4 months, the refined lines are well maintained. However, if you gain weight or as aging progresses, facial volume and lines may change again. The duration of maintenance can vary depending on lifestyle habits, so we recommend consulting about the management timing based on your condition.

How many sessions of The L are needed to see results?

For the first round of The L, 3 sessions are typically performed at 4-week intervals. Thereafter, to maintain the refined contour, receiving 1 session every 4 months helps sustain the effects.

Who is The L especially recommended for? Are there cases where it is difficult to receive?

The L is particularly well suited for people whose face appears overall large and whose contours look uneven, and for those whose jawline appears bulky and dull. On the other hand, if you have hollow areas due to lack of facial fat, a volume-restoring procedure may take priority, so a consultation is needed.

What is The L?

The L is a treatment that reduces unnecessarily enlarged contours to create a smaller face through simple injection procedures without surgery.

01 Smaller face
02 Jawline
03 Skin Texture

Mechanism

How The L works

The L precisely injects a patented injection formula into the areas that make up the facial contour, gradually reducing volume in bulky areas. It is injected in small amounts into areas with blunt lines, such as the double chin, jawline, and temples, to refine a delicate contour that considers the overall balance of the face.

HEALHOUSE’S the L solution

Heal House's The L is different

HEAL POINT 01

Genuine products Accurate shots Exact dosage

All five Heal House branches use only genuine products, under the same standards. This applies to tips, cartridges, and medications alike. We use the agreed number of shots and dosage as planned, and disposable supplies are never reused. We deliver the exact amount precisely where it is needed.

HEAL POINT 02

Same procedure, different design

Even with the same equipment and medication, results vary depending on who receives the treatment and how it is applied
. This is because skin type, thickness, and degree of sagging differ from person to person. A higher number of shots or larger dosage does not necessarily mean better results.
A different design leads to different outcomes.
