Under-Eye Fine Line Treatments: Where to Start? A Guide to Choosing by Wrinkle Type

If you are considering procedures for fine lines around the eyes, the first thing to do is not choosing the type of procedure. The key is first distinguishing whether your wrinkles are 'wrinkles that appear when you smile' or 'wrinkles visible even when your face is at rest.' For dynamic wrinkles (crow's feet) that form only when making facial expressions, botulinum toxin is the primary choice. For static wrinkles that remain even with a neutral expression, regenerative and elasticity-improving treatments such as lasers, skin boosters, radiofrequency (RF), and ultrasound are appropriate.

Many people lump them together under the single term 'eye wrinkles,' but different causes require different answers. That is why great results usually come not from a single treatment, but from a combined design that approaches dynamic wrinkles with Botox, and static wrinkles and elasticity with other procedures. Below, we will break this down by type.

🔍 What type of eye wrinkles do I have?

Wrinkles around the eyes are largely divided into two types. This distinction is the starting point for choosing a treatment.

• Dynamic wrinkles: Wrinkles that appear when you smile or frown. They occur because the **orbicularis oculi muscle** around the eyes contracts, folding the skin. They are commonly called 'crow's feet.'

• Static wrinkles: Wrinkles that remain like etched lines even when your face is at rest. They are caused by a reduction in collagen and elastin along with photoaging, which makes the skin itself thin and lose its elasticity.

The eyelid skin is about 0.5 mm thick, making it among the thinnest on the face. Because it is that much more sensitive to irritation, swelling, hyperpigmentation, and procedure side effects, a more careful approach is essential.

📌 Key Summary: If they form when you smile, approach them as dynamic wrinkles (Botox); if they are visible even when resting, approach them as static wrinkles (lasers, skin boosters, lifting).

💉 Why botulinum toxin for dynamic wrinkles?

The direct cause of crow's feet is the repetitive contraction of the orbicularis oculi muscle. Botulinum toxin (Botox) relaxes the excessive movement of this muscle, reducing the very force that folds the skin. This is why it is considered the first-line choice for dynamic wrinkles.

The effects do not appear immediately. Typically, the effect begins to show within 3 to 7 days, reaches its peak after about 2 weeks, and lasts for an average of 3 to 4 months. Because the eye area is delicate, treatment is usually calibrated to about 2 to 3 points per side, ranging from about 10 to 24 units in total for both sides. It is also good to know that direct unit-to-unit conversion is impossible across different brands because each product has its own unit standard.

People often hear concerns that 'getting Botox for a long time will build tolerance or make it ineffective,' but on the contrary, reports show a tendency for the duration to extend as the muscle gradually weakens through repeated treatments. However, excessive dosages or misplaced injections can make facial expressions look unnatural, so delicate technique is especially crucial around the eyes.

Note that it is generally contraindicated during pregnancy and breastfeeding because safety has not been established. Please make sure to inform your doctor during consultation.

📌 Key Summary: Botox is used for dynamic wrinkles; onset is 3–7 days, peaking at 2 weeks, lasting 3–4 months, and it is contraindicated during pregnancy/breastfeeding.

🧴 What procedures are suitable for static wrinkles and thinned skin?

Wrinkles that remain even with a neutral expression and diminished skin elasticity cannot be resolved with Botox alone. An approach that regenerates the skin itself is necessary.

Skin Boosters — Rejuran I / Juvelook I

These treatments change the 'environment' of the thin, dry skin around the eyes.

• Rejuran I (PN/PDRN): Formulated with polynucleotides derived from salmon DNA, it aids skin regeneration and improves elasticity. Small bumps (embossing) naturally appear for 1 to 3 days post-procedure before subsiding.

• Juvelook I (PDLLA): Combines high-molecular PDLLA with hyaluronic acid to induce collagen production.

Rather than a single session, around 3 repeated sessions are typically recommended for both treatments, as their effects build up gradually.

Energy-Based Devices — Lasers, RF, Ultrasound

The difference between radiofrequency (RF) and ultrasound is 'how deep they reach.' Eye Thermage works on the dermal layer, while HIFU reaches deeper into the SMAS layer, offering different qualities of lifting. When undergoing laser procedures, wearing eye protection shields is mandatory; omitting them risks retinal damage.

What energy-based treatments share in common is that their effects appear gradually. Collagen remodeling should be evaluated over 1 to 3 months or more. Just because results are not instantly visible does not mean the treatment has failed.

📌 Key Summary: For static wrinkles and elasticity, skin boosters (around 3 sessions) along with lasers, RF, or ultrasound are used, and results should be monitored over 1 to 3 months or more.

⚠️ Why are under-eye fillers considered 'high difficulty'?

When the under-eye area is sunken or hollow, hyaluronic acid fillers are sometimes used to restore volume. The duration is about 6 to 18 months depending on the area and product, and if issues arise, they can be dissolved with hyaluronidase.

The problem is that the under-eye skin is exceptionally thin. Because the skin is so thin, placing filler too superficially can easily cause the **Tyndall effect**, where a bluish hue shows through, and swelling can last a long time. Although rare, serious complications such as skin necrosis or visual impairment from intravascular injection have been reported, requiring immediate action if sudden pain, skin color changes, or visual disturbances occur.

Therefore, the practitioner's anatomical understanding and skill determine the results of under-eye fillers. Onlif places great importance on safety and natural results in such delicate areas through a structure where each practitioner only handles the procedures they excel at most. As a side note, for protruding under-eye fat or severe skin sagging, surgical options like lower blepharoplasty (under-eye fat repositioning) are also considered, but these are separate choices involving recovery burdens and risks. Onlif prioritizes non-incisional dermatological procedures for improvement.

📌 Key Summary: Under-eye fillers are high-difficulty procedures with risks of the Tyndall effect and vascular complications, making practitioner skill and an emergency response system critical.

🧩 Do I have to pick just one? — The logic of combination design

To answer upfront: no. A combined design that approaches dynamic wrinkles with Botox, and static wrinkles and elasticity with lasers, skin boosters, and lifting delivers far more natural results. Trying to address every wrinkle with a single modality often leads to over-treatment, resulting in an unnatural appearance.

This aligns with what Onlif pursues: rather than altering the shapes of the eyes, nose, or mouth, an approach that 'lifts away' the aging and loss of elasticity that obscure your inherent appearance. Subtle, refined, and natural.

📌 Key Summary: A combined design tailored by wrinkle type looks more natural than a single treatment, and non-excessive improvement is key.

📋 Pre-procedure checklist and post-procedure care

Pre-Procedure Checklist

• Anticoagulants, aspirin, omega-3, high-dose vitamin E, and alcohol increase the risk of bruising, so discuss in advance whether to temporarily discontinue them.

• Be sure to disclose any dry eye syndrome, glaucoma, or history of LASIK/LASEK. Procedures around the eyes can affect blinking mechanics or the tear film.

• For fillers or under-eye treatments, it is wise to ask whether the clinic keeps hyaluronidase on hand, uses eye protection shields, and has a protocol for handling side effects.

Post-Procedure Care

• Sun protection is paramount. Since photoaging is a primary cause of eye wrinkles, SPF 30 or higher and PA+++ or higher are generally recommended.

• Protect the delicate under-eye skin barrier with adequate moisturizing.

• Anti-wrinkle functional ingredients like retinoids require consistent use for at least 3 to 6 months or more to evaluate results. Because the eye area is delicate, start cautiously with low concentrations.

📌 Key Summary: Discontinuing bruise-inducing substances and disclosing ophthalmic history are key before procedures; sun protection and moisturizing are vital for maintaining post-procedure results.

❓ Frequently Asked Questions (FAQ)

Are the treatments different for outer-eye wrinkles that appear only when smiling versus fine under-eye lines visible at rest?

Yes, they are different. For dynamic wrinkles that crease when smiling, botulinum toxin is the primary choice. For static wrinkles that persist even without facial expressions, regenerative and elasticity-improving treatments like lasers, skin boosters, RF, and ultrasound are appropriate. When both types coexist, a combined design is necessary.

Can eye-area Botox make my facial expressions look unnatural or make my eyes look smaller?

When the dosage and injection sites are precise, you can soften wrinkles while preserving natural expressions. However, excessive doses or improper placement can cause unnatural stiffness, making delicate calibration vital. In the eye area especially, practitioner precision dictates the outcome.

What are the differences between Rejuran I, Juvelook I, and hyaluronic acid skin boosters?

Rejuran I focuses on skin regeneration using PN derived from salmon DNA, while Juvelook I focuses on stimulating collagen production using PDLLA. Hyaluronic acid skin boosters are primarily aimed at deep hydration and skin texture refinement. All of these typically build results through approximately 3 repeated sessions.

How are Eye Thermage (RF) and HIFU (Ultrasound) different?

They differ in depth of action. Eye Thermage targets the dermal layer to promote collagen regeneration and tightening, whereas HIFU reaches deeper into the SMAS layer to induce lifting. RF is generally favored when skin texture and elasticity are the main concerns, while ultrasound is considered for sagging and lifting; the exact choice is determined through consultation.

Can I undergo treatments if I have dry eye syndrome or a history of LASIK/LASEK?

It is possible in many cases, but you must disclose this history in advance. Because periorbital procedures can influence blinking or the tear film, adjustments must be made taking your ophthalmic condition into account. Rather than self-assessing, evaluating together during a consultation ensures safety.

Can I undergo eye wrinkle treatments during pregnancy or breastfeeding?

Botulinum toxin is generally contraindicated because safety during pregnancy and breastfeeding has not been established. For other procedures as well, it is often safer to postpone treatment; we recommend informing your provider of your condition and deciding through consultation.

What home care is needed to maintain the results of eye-area procedures long term?

The most critical step is sun protection. Because photoaging is a leading cause of eye wrinkles, consistent application of sunscreen with SPF 30+ and PA+++ or higher is recommended. Pairing this with thorough moisturizing and long-term use of functional ingredients like retinoids will help sustain results.

Things to Check Before Choosing a Clinic for Eye Wrinkle Treatments

Even for the exact same procedure, results and recovery can vary depending on where, by whom, and how it is performed. Asking the following questions during your consultation will help you make an informed decision.

• Do they perform this procedure frequently? — Every clinic has treatments they specialize in. Check whether they perform eye wrinkle procedures regularly.

• Can you verify the products and devices used? — Ask whether product names and authenticity (whether they are import-approved products, whether there is a process to verify unopened packaging) can be confirmed during consultation.

• Do they explain the cost breakdown? — Rather than just hearing a lump sum, you need an explanation of which products, what amounts, and which areas are treated to make an informed choice.

• Do they design treatments considering overall facial balance? — Even for the same procedure, injection points and quantities vary depending on facial shape, skin condition, and left-right asymmetry.

• Do they explain adverse reactions and the recovery process upfront? — A clinic that proactively explains potential adverse events and management protocols alongside expected changes is preferable to one that only discusses benefits.

• Is there a clear follow-up channel after the procedure? — Check whether checkpoints for progress monitoring, contact methods in case of anomalies, and revisitation standards are clearly established.

How Onlif Clinic Approaches Eye Wrinkle Treatments

• We divide responsibilities by specialization — Operating on the philosophy that a single doctor cannot master every single procedure, Onlif assigns dedicated physicians by specialty area.

• We verify products and devices together during consultation — We guide you through the products used and the unboxing verification process during your consultation.

• Costs are guided with a breakdown after diagnosis — Because target areas, dosages, and treatment scopes vary by person, we explain what costs what along with the diagnosis.

• We design around overall facial harmony — Viewing the face along three axes—texture, balance, and signs of youth—we formulate plans to refine aspects that obscure your natural image rather than altering your features.

• We explain adverse reactions and recovery beforehand — Along with expected improvements, individual differences, potential side effects, and management protocols are guided prior to treatment.

• We monitor progress together after treatment — If follow-up evaluation is needed during recovery, we provide guidance for clinic revisits and direct communication channels.

If you are considering procedures for fine lines around your eyes, it is best to first evaluate what is feasible and what is limited in your current skin condition. Accurate diagnosis and treatment planning can only be determined through an in-person evaluation. Schedule a consultation at Gangnam Onlif Clinic to find out.
