The skin around your eyes is one of the first areas to show signs of fatigue, stress, and ageing. Dark circles, puffiness, and fine lines can become more noticeable over time, making a consistent under eye skincare routine an important part of daily care.
Knowing how to use under eye serum correctly can make a meaningful difference in your routine. It's not just about choosing the right product, it's also about applying it at the right time, in the right way, and as part of a routine designed to support your skin's natural rhythm.
The Oteria Time Travel Under Eye Serum is part of the Yawn routine, created to complement the skin's overnight recovery period. With Sweet Orange to help reduce the appearance of eye bags and Brown Algae to support collagen production and improve eye contour luminosity, it is designed to target puffiness, dark circles, and visible signs of eye ageing as part of your nightly skincare routine.
In this guide, you'll learn when to apply under eye serum, how to use it correctly, and how to build an effective eye serum routine for healthier looking under eye skin.
What is an Under Eye Serum?
An under eye serum is a lightweight skincare product specifically formulated for the delicate skin around the eyes. Unlike facial creams, eye serums are designed to absorb quickly and deliver targeted care where signs of tiredness and ageing are often most visible.
A quality eye serum can become an essential step in your eye care routine, especially if you're looking to address concerns such as:
-
Dark circles
-
Under-eye puffiness
-
Eye bags
-
Fine lines and crow's feet
-
Dull-looking eye contour
The Oteria Time Travel Under Eye Serum is formulated to help improve the appearance of these common concerns through two carefully selected ingredients:
-
Sweet Orange, which helps provide instant relief from the appearance of eye bags.
-
Brown Algae, which supports collagen production and cell vitality while enhancing eye contour luminosity.
With regular use as part of your night eye serum routine, the formula is designed to visibly reduce puffiness in as little as three hours while helping reduce the appearance of dark circles and crow's feet within one week.
Because the formula penetrates quickly into the skin, it works efficiently during your evening skincare routine, making it a valuable addition to your daily under eye skincare regimen.

Why is the Under-Eye Area Different?
The skin beneath your eyes is naturally thinner and more delicate than the skin on the rest of your face. It also has fewer oil glands, making it more vulnerable to dryness and visible signs of fatigue.
This delicate area is often the first place where you may notice:
-
Puffiness after a long day
-
Dark circles
-
Crow's feet
-
Reduced brightness around the eyes
-
Early visible signs of ageing
Because of its delicate nature, the under-eye area benefits from products specifically developed for eye care rather than general facial skincare.
Using a dedicated under eye serum allows you to care for this sensitive area with a lightweight formula designed for targeted application. The roller applicator of the Oteria Time Travel Under Eye Serum also makes application simple while helping you apply the serum precisely along the orbital bone as recommended.
Adding a dedicated eye serum to your skincare routine helps ensure your under-eye area receives focused care instead of relying solely on products designed for the rest of the face.
Why Timing Matters When Using an Under Eye Serum
One of the most common questions people ask is whether timing really affects the results of an under eye serum.
The answer is yes.
Applying your eye serum at the right time allows it to become part of a consistent routine rather than an occasional treatment. Consistency helps ensure the serum is used regularly, allowing the formula to support the appearance of healthier-looking under-eye skin over time.
The Oteria Time Travel Under Eye Serum belongs to the Yawn routine—Oteria's night-time skincare collection.
The Yawn routine focuses on supporting the skin's overnight recovery period by working in harmony with the skin's natural repair and regeneration processes that take place while you sleep. This makes night-time the ideal time to include the serum in your daily eye serum routine.
If you already follow Oteria's Circadian Rhythm Skincare approach, each routine is designed for a specific phase of the day. For example:
-
Rise: Start your morning with White Tea Face Wash to cleanse your skin.
-
Shine: Refresh during the day with Radiant Kiwi Mist.
-
Chill: Prepare your skin for the evening with Plumpy Skin Serum.
-
Yawn: Complete your routine at night with the Time Travel Under Eye Serum to support overnight eye care.
Each routine complements a different part of your day, helping create a complete skincare ritual that follows your skin's natural rhythm.
When Should You Apply Under Eye Serum?
If you're wondering when to apply under eye serum, the answer depends on the product and the routine it is designed for.
Since the Oteria Time Travel Under Eye Serum is part of the Yawn collection, it is intended to be applied during your evening skincare routine before you go to bed.
Using it at night allows it to become part of your overnight eye care routine, aligning with the Yawn philosophy of supporting the skin's natural repair processes during sleep.
A simple night eye serum routine may look like this:
-
Cleanse your face.
-
Apply your under eye serum.
-
Continue with the remaining products in your Yawn skincare routine.
Building a consistent habit is often more important than occasional application. Regular nightly use helps you make the most of your under eye skincare routine while supporting the visible improvements described on the product.

How to Apply Under Eye Serum Step by Step
Learning how to apply eye serum correctly helps ensure even application while keeping the delicate eye area comfortable.
Follow these simple steps:
Step 1: Begin with Clean Skin
Start your evening skincare routine by cleansing your face to remove impurities before applying your eye serum.
Step 2: Use the Roller Applicator
The Oteria Time Travel Under Eye Serum comes with a roller designed for easy application.
Using the roller, gently apply the serum underneath your eyes along the orbital bone, following the usage instructions provided with the product.
Step 3: Apply Evenly
Move the roller smoothly beneath each eye without applying excessive pressure. The lightweight serum spreads easily across the targeted area.
Step 4: Continue Your Night Routine
Once the serum has been applied, continue with the remaining products in your evening skincare routine.
Step 5: Stay Consistent
The best eye serum routine is one you follow consistently. Incorporating your under eye serum into your nightly routine helps you maintain regular care for the delicate eye area.
Where Should You Apply Under Eye Serum?
Knowing how to use under eye serum is only part of the process—knowing exactly where to apply it is equally important. The skin around your eyes is thinner and more delicate than the rest of your face, so applying the serum correctly helps ensure a comfortable application as part of your daily under eye skincare routine.
When using an under eye serum, apply it only to the under-eye area along the orbital bone. This is the area beneath your eyes where the skin benefits most from targeted care.
If you're using the Oteria Time Travel Eye Serum, simply use the built-in roller to glide the serum gently under each eye along the orbital bone, following the product directions. The lightweight formula is designed to fit seamlessly into your evening eye serum routine.
Avoid applying the serum directly inside the eyes or too close to the lash line. Using the correct placement helps make your eye care routine both comfortable and consistent.
Should You Apply Under Eye Serum Before or After Moisturizer?
One of the most frequently asked questions is whether eye serum before moisturizer is the correct order.
The answer is yes.
As a general skincare routine guideline, apply your under eye serum after cleansing and before your moisturizer. This allows the serum to be applied directly to clean skin before sealing your routine with a cream or moisturizer.
A simple order looks like this:
-
Cleanse your face.
-
Apply your under eye serum.
-
Follow with your facial moisturizer.
-
Complete the rest of your evening skincare routine.
Following this sequence creates a structured eye serum routine and helps you stay consistent with your nightly skincare habits.
Common Mistakes to Avoid
Even the best under eye serum works best when used correctly. Avoiding a few common mistakes can help make your under eye skincare routine more effective and comfortable.
Applying Too Much Product
Using more serum doesn't necessarily improve results. A small amount is enough for both under-eye areas.
Applying Too Close to the Eyes
Keep the serum on the orbital bone instead of applying it directly near the eyes or lash line.
Skipping Your Routine
Visible skincare improvements often come with regular use. Following a consistent night eye serum routine is more beneficial than applying it occasionally.
Rubbing the Skin Aggressively
The under-eye area is delicate. Use gentle movements when applying your serum.
Using Products at the Wrong Time
Since the Time Travel Eye Serum belongs to Oteria's Yawn collection, it is designed to complement your nighttime skincare routine, when the skin naturally enters its overnight recovery phase.
