You want fuller, more hydrated lips, but you’re afraid that lip enhancement will look unnatural or stiff when you smile? Restylane Kysse, a hyaluronic acid filler specifically designed for the lips, is made for “dynamic naturalness” – it moves with your expressions, staying soft and flexible when you speak or smile. Plus, with single‑point injections as fine as 0.01ml, the borders are virtually invisible. After reading this, you’ll know how to communicate your desired lip shape with a Korean doctor.
Restylane Kysse is a hyaluronic acid filler developed by Galderma (Sweden) specifically for the lips, and it is the first FDA‑approved product exclusively for lip enhancement. Its core principle is built on two technological breakthroughs:
XpresHAn Technology™ Cross‑linking: Kysse uses a unique XpresHAn Technology™ cross‑linked gel formulation that forms a flexible yet supportive mesh structure in the lip tissue. This allows the filler to blend naturally with the soft tissue of the lips, moving flexibly with every smile, word, and expression – without stiffness or a “plastic” look.
OBT (Optimal Balanced Technology) Dynamic Balance: Kysse’s gel structure fills the lips in a mesh‑like manner, achieving a perfect balance between flexibility and support. Compared with traditional lip fillers, Kysse requires less volume to achieve the desired fullness while maintaining a natural gloss and hydration.
In one sentence: Restylane Kysse is a “dynamic hyaluronic acid” – designed for lip expressions, keeping lips full, soft, and glossy during natural movement.
Restylane Kysse lip filler is especially suitable for those with:
Lip characteristics: Naturally thin lips, asymmetrical lip shape, lack of fullness; those wanting to improve lip contour, define the lip tubercle, or enhance the smile line; those with age‑related collagen loss and deepening lip lines.
Psychological profile: Seeking a natural‑looking result rather than an exaggerated “sausage lip”; wanting the lips to remain soft and natural during dynamic expressions; sensitive to pain and preferring a shorter swelling period.
Additional indication: Kysse can also be used to improve perioral lines (smoker’s lines) – the vertical lines around the lips.
Absolute contraindications: Pregnancy or breastfeeding; known allergy to lidocaine or amide‑type anaesthetics; coagulation disorders or taking anticoagulants; active infection, inflammation, or tumours in the treatment area.
Based on injection sites, dosage, and combination protocols, mainstream dermatology clinics in Gangnam, Seoul, offer the following three Restylane Kysse lip plans. The comparison below can help you communicate with your physician:
| Plan Type | Injection Sites | Recommended Dose | Main Effect | Duration | Reference Price (KRW only) |
|---|---|---|---|---|---|
| Basic Lip Enhancement | Full upper and lower lips | 0.5 – 1.0 cc | Increases fullness, improves dryness | 6 – 12 months | ₩319,000 – 660,000 |
| Lip Contour Sculpting | Tubercle, Cupid’s bow, smile line | 0.5 – 1.0 cc | Adjusts proportions, refines contour | 6 – 12 months | ₩400,000 – 900,000 |
| Perioral Rejuvenation (including lip lines) | Lips + perioral vertical lines | 1.0 – 1.5 cc | Enhances lips + smooths fine lines | 6 – 12 months | ₩600,000 – 1,320,000 |
Korean doctors’ advice: The price of 1cc of Restylane Kysse at mainstream Gangnam clinics ranges from ₩319,000 to 660,000. When combined with skin regenerative treatments like Rejuran, the duration can be extended from the usual 6‑8 months to about 10 months. Actual costs vary by physician experience, clinic positioning, and injection volume.
Step 1 – Consultation & 3D imaging: The Korean physician evaluates lip proportions, symmetry, and your expectations, determining injection points and dosage.
Step 2 – Anaesthesia: Topical lidocaine anaesthetic cream is applied for 20‑30 minutes. Kysse itself also contains lidocaine, providing continuous anaesthesia during injection, so pain is minimal.
Step 3 – Injection: Korean doctors commonly use a progressive mucosal‑layer filling technique, advancing layer by layer from the inner lip outward. This allows single‑point injections as fine as 0.01ml, ensuring almost zero visible borders – giving a naturally born look. The procedure takes about 20‑30 minutes.
Step 4 – Post‑treatment: Ice packs are applied for 15‑20 minutes, then you may leave. Avoid touching or pressing the injected area for 24 hours.
Immediate effect: Lips become instantly fuller and better contoured. Thanks to XpresHAn Technology™, the filler integrates naturally with lip tissue – 96% of patients reported that the results looked very natural.
Progressive effect: After the mild swelling subsides within 48‑72 hours, the lip shape becomes even more natural and refined. Kysse also improves lip texture and colour, making the lips look more hydrated and glossy.
Duration: Restylane Kysse lasts 6‑12 months, with some individuals experiencing results beyond 12 months. Clinical data show that 77% of patients maintained at least a 1‑grade improvement in lip fullness at 6 months. Touch‑ups are recommended before the effect fully fades.
Q1: What is the difference between Restylane Kysse and other lip fillers?
A: Kysse is the first lip‑specific HA filler using XpresHAn Technology™, designed for dynamic expression. Compared with other lip fillers, Kysse focuses on dynamic naturalness – keeping lips soft and flexible while speaking or smiling, without stiffness. It also requires less volume to achieve ideal fullness.
Q2: Is the injection painful?
A: Almost painless. Topical anaesthetic is applied beforehand, and Kysse itself contains lidocaine for continuous numbing. Most people report only a mild pinprick sensation. The whole procedure takes 20‑30 minutes.
Q3: How long is recovery? Can I fly back the same day?
A: Mild swelling or bruising may occur for 24‑48 hours and fully resolves within one week. Normal cleansing, skincare, and makeup can be resumed after 24 hours. You can leave the clinic and fly on the same day – it does not affect your travel plans.
Q4: Which clinics in Gangnam are good for Restylane Kysse?
A: Clinics such as Kleam Clinic, Innee Dermatology, and Kodi Plastic Surgery offer Restylane Kysse lip filler services. Choose an authorised clinic that uses KFDA‑certified genuine products and has a physician with extensive lip injection experience.
Q5: How long do results last? Do I need regular touch‑ups?
A: A single session lasts 6‑12 months, with some individuals seeing results beyond 12 months. When combined with skin regenerative treatments like Rejuran, duration can extend to about 10 months. Annual maintenance injections are recommended before the effect fades.
Restylane Kysse is a medical aesthetic product, and potential side effects include:
Common short‑term reactions: Redness, swelling, bruising, pain, or tenderness at the injection site – usually subside within 24‑48 hours. Kysse causes less swelling compared with other lip fillers.
Rare complications: In very rare cases, nodules, granulomas, infection, or vascular embolism may occur. Choosing a certified clinic and an experienced physician greatly reduces these risks.
Rational advice:
1. Choose a certified medical institution accredited by the Korean Ministry of Health and Welfare, and confirm the product is genuine with KFDA anti‑counterfeit labelling.
2. Discuss your desired lip shape – whether “naturally full” or “refined sculpting” – to determine injection points and dosage.
3. Stop aspirin, vitamin E, and fish oil 2 weeks before treatment to reduce bleeding risk.
4. Avoid touching the lips for 24 hours; avoid extremely hot or cold foods, saunas, and hot baths for 1 week; avoid external pressure on the lips for 2‑3 weeks.
