Dark circles, puffiness, and tired-looking eyes are among the most common skincare concerns. While choosing the right under eye serum is important, knowing when to use under eye serum can make your skincare routine more effective.
Many people wonder whether an eye serum should be used in the morning, at night, or both. The answer depends on how the product is designed to work and how it aligns with your skin's natural repair cycle.
At Oteria, skincare follows the philosophy of Circadian Rhythm Skincare a routine that works with your skin throughout different phases of the day. Instead of treating every hour the same, each routine is created to support what your skin naturally needs at that particular time.
For overnight eye care, Oteria's Time Travel Eye Serum is part of the Yawn Routine, designed to support the skin's natural nighttime recovery period.
Why Does Timing Matter in Skincare?
Your skin doesn't behave the same way throughout the day. It continuously responds to environmental conditions during waking hours and shifts its focus to recovery while you sleep.
This is why eye serum timing plays an important role in any effective under eye skincare routine.
During the day, the delicate skin around your eyes is exposed to factors like:
-
Daily environmental stress
-
Long hours of screen time
-
Fatigue from work or travel
-
Natural dehydration throughout the day
At night, your skincare routine becomes less about protection and more about supporting your skin while it goes through its natural overnight renewal process.
This is the foundation behind Oteria's Circadian Rhythm Skincare, where products are matched to your skin's changing needs instead of following a one-size-fits-all approach.
When your eye serum routine aligns with your skin's natural rhythm, it helps create a more intentional and consistent approach to caring for the under-eye area.

Morning vs Night: What's the Difference?
One of the most searched skincare questions is whether an eye serum should be applied in the morning or before bed.
The reality is that morning vs night eye serum isn't about choosing a universally "better" time it's about using a product the way it was formulated and intended to be used.
Morning Eye Care
Morning skincare is generally focused on preparing your skin for the day ahead. Many routines prioritize cleansing, hydration, moisturization, and sun protection before stepping outside.
Within Oteria's Circadian Rhythm Skincare philosophy, this corresponds to the Rise Routine, which prepares your skin for the start of the day. A routine may naturally include products such as:
-
Sunkissed Shield Sunscreen SPF 50 PA++++ for daytime UV protection
These products are designed for the morning phase of your skincare journey.
Night Eye Care
Night is when your skincare routine shifts towards recovery.
This is why under eye serum at night is an important part of Oteria's Yawn Routine.
The Time Travel Eye Serum is formulated with:
-
Sweet Orange, which helps provide instant relief for eye bags.
-
Brown Algae, which helps boost collagen production and cell vitality while enhancing eye contour luminosity.
With regular use, the serum is designed to:
-
Reduce puffiness in as little as 3 hours
-
Help reduce dark circles and crow's feet in one week
-
Enhance eye contour luminosity in one week
Its lightweight formula penetrates deeper and faster into the skin, making it suitable for your dedicated night eye care routine.
Using the roller applicator, simply apply the serum along the orbital bone before bedtime as part of your eye serum routine.
Benefits of a Dedicated Night Routine
Your skin follows a natural cycle throughout the day. During the night, it shifts its focus from protecting itself against external stressors to supporting repair and renewal. This is why many people choose to make night eye care an important part of their daily skincare routine.
When deciding when to use under eye serum, applying it consistently at night can fit naturally into your routine, especially if your skincare is designed around your skin's overnight recovery cycle.
Oteria's Yawn collection is created with this philosophy in mind. The Yawn routine supports the skin's natural overnight regeneration process, making it an ideal time to include the Time Travel Under Eye Serum in your under eye skincare routine.

Why Use an Under Eye Serum at Night?
Using an under eye serum at night allows you to maintain a consistent routine while your skin follows its natural overnight recovery process. According to Oteria's Circadian Rhythm Skincare philosophy, nighttime is when skin emphasizes:
-
Cell turnover
-
Repair processes
-
Skin regeneration
-
Natural overnight rejuvenation
The Time Travel Under Eye Serum is designed to complement this nighttime routine.
What Makes Time Travel Under Eye Serum Different?
The serum combines carefully selected ingredients that target common under-eye concerns.
Sweet Orange
-
Helps provide instant relief for the appearance of eye bags.
Brown Algae
-
Helps support collagen production.
-
Improves eye contour luminosity.
-
Helps address visible signs of eye ageing.
With regular use, the serum is designed to:
-
Reduce the appearance of puffiness in as little as 3 hours
-
Help reduce the appearance of dark circles and crow's feet within one week
-
Improve eye contour luminosity with continued use
Because the lightweight formula penetrates quickly into the skin, it delivers active ingredients efficiently to the under-eye area as part of your regular eye serum routine.
Can You Use an Under Eye Serum Twice a Day?
Yes, many people include an eye serum in both their morning and evening skincare routine. The most important factor is using it consistently.
If you're wondering when to use under eye serum, here's a simple approach:
Morning Routine
Morning application can help complete your daily under eye skincare routine before starting the day.
Apply the serum:
-
After cleansing
-
Before moisturizer
-
Before sunscreen if you're following a complete morning routine
Night Routine
For those following Circadian Rhythm Skincare, the evening routine offers an ideal opportunity to include the Time Travel Under Eye Serum as part of the Yawn routine.
Using the roller applicator, gently apply the serum under the eyes along the orbital bone before the rest of your nighttime skincare.
Consistency Matters More Than Timing
Whether you prefer morning, night, or both, the biggest factor is maintaining a regular eye serum routine.
Consistent application allows the product to work as intended as part of your everyday under eye skincare routine.

Building a Routine That Works for You
An effective skincare routine doesn't have to be complicated. Instead, it should match your daily schedule while supporting your skin throughout different times of the day.
If you're following Oteria's Circadian Rhythm Skincare philosophy, each routine is designed with a specific purpose:
-
Rise: Start your morning with products like White Tea Face Wash to cleanse and prepare your skin for the day.
-
Shine: During the day, Sun Kissed Suncare Gel helps support your daytime skincare routine.
-
Chill: As your day slows down, Plumpy Skin Serum fits naturally into your evening skincare ritual.
-
Yawn: Finish your routine with Time Travel Under Eye Serum, designed to complement your skin's overnight repair and regeneration cycle.
Rather than focusing only on one product, this approach encourages building a routine that works in harmony with your skin's natural rhythm.
