Vascular dark circles
Rejuran HB 1ml or Dr Samantha's Signature Glow Booster Eye 1.8ml. Polynucleotides thicken the dermis, reducing how much vessel shows through thin skin.
Dark eye circles live in the crescent under your eye, not just on the surface. Dr Samantha injects 1ml of a custom booster (rejuran with hyaluronic acid, whitening ingredients, and vitamins) into the exact crescent where pigmentation pools. Lightening possibly visible. The protocol usually needs multiple sessions, 5 to 10.

Dark eye circle treatment patients usually arrive having tried eye cream, retinol, concealer, more sleep, less screen time. The reason none of those worked is that dark eye circle treatment are not a single skin problem. They are three different anatomical patterns, often layered together. Searches for dark eye circle removal singapore land on dozens of clinic ads promising one-shot fixes; the honest answer is that the right treatment depends on which type you have.
A 20-minute consultation with Dr Samantha runs the diagnostic first. Most under-eyes have two of three types layered. Treating the wrong one wastes sessions and money. Effective dark eye circle treatment patients receive at Nexus is matched to which type or types are layered, not picked from a generic menu.
Technique placement on every single procedure has to be deliberate and accurate. Wrong layer equals suboptimal results. The crescent runs along the orbital bone from the inner corner outward. Vascular pooling, pigment, and structural hollow all converge inside that exact curve. A booster injected even a few millimetres above or below the crescent lands in surface skin or fat that is not driving your darkness. Eye creams reach almost none of it. Dr Samantha's signature mix carries rejuran, hyaluronic acid, peptides, amino acids, and a trace anti-inflammatory base, then delivers it into the crescent itself.
The under-eye crescent sits below the surface, where topical actives rarely reach in clinically useful concentrations.
The most common under-eye fear is the look of overfilled tear troughs from filler done elsewhere. Lumpy migration, baggy hollows, or a permanent puffy look that survives years past the treatment. Two protocols at Nexus reduce this risk: depth-calibrated technique on filler placement, and a strong preference for polynucleotide-based regenerative protocols (Rejuran HB, Dr Samantha's signature mix) over hyaluronic acid filler when the diagnosis is vascular or pigmented rather than structural.
Tear trough filler is reserved for the structural-hollow category specifically. Vascular and pigmented dark circles get regenerative protocols, because filling vessels does not fix vessels.
Most aesthetic clinics in Singapore default to one option for every dark eye circle treatment patient. Tear trough filler if they sell filler. Pico laser if they sell laser. Rejuran if they sell skin booster. The diagnostic step is skipped because it slows the sale.
At the 20-minute consultation, Dr Samantha maps your specific mix across four axes. Every undereye shows up as a combination, never just one type. Genetics and lifestyle drive different proportions of:

The protocol that fits the read is what gets recommended, not the protocol Nexus has on promotion.
An honest filter before any consultation. Some under-eye concerns sit outside what bio-regenerative protocols and filler can address.
If your dark circle is vascular and you arrived asking for laser, Dr Samantha will tell you laser is not the right tool for vessels visible through thin skin. The protocol changes when the cause changes.
Diagnostic consultation
Dr Samantha runs the 4-point read (vessel, pigment, structural, skin quality) and maps your specific mix across all four. Most patients are a combination, not a single type. Photos taken under standardised lighting.
Numbing + skin prep
Topical anaesthetic on the under-eye crescent for 30 to 45 minutes. The under-eye area is cleansed and marked.
Treatment
Dr Samantha delivers the matched protocol via microneedle technique, depth-titrated. Same-day combo for most patients: Pico Laser with the Signature Glow Booster Eye (Rejuran HB mix). HIFU and the Microneedling Rejuran Tone-Up Booster are scheduled on separate days when indicated.
Cool down + aftercare brief
Cold compress, brief on the 48-hour aftercare window, photography for the patient record. Appointment for the next session set if a course is recommended.
Total chair time is around 50 minutes. Dr Samantha personally delivers every booster injection.
| Treatment | Sessions | Interval | Duration of results |
|---|---|---|---|
| Signature Glow Booster Eye | 5 to 10 sessions | 4 weeks apart | Maintenance after course |
| Tear Trough Filler | 1 session | Touch-up at 12 months if needed | 12 to 18 months |
| Botulinum Toxin under-eye fine lines | 1 session | Top-up at 4 to 6 months | 4 to 6 months |
| Microneedling Rejuran Tone-Up Booster | 5 sessions recommended | Every 4 weeks | Maintenance after course |
Durability depends on age, skin tone, sun exposure, and aftercare. Most patients hold results with one or two maintenance sessions a year.
Most effects are mild and transient. The honest split:
Aftercare decides how well the result holds. The crescent zone is thin skin with fragile vessels. Most people want a permanent fix; the honest reality is that aftercare and maintenance are what extend the lighter look month over month. Three windows matter:
Calm the under-eye
Cold compress as often as needed for the first 48 to 72 hours. No alcohol or exercise for the first 24 hours after procedure. No makeup over the injection points for 12 hours. Sleep slightly elevated to reduce overnight swelling.
Daily care matters more than any single product
Daily care matters more than any single product. Layer Calecim serum (80% stem cell, designed for firming) over your barrier-supporting routine. Used in place of a standard eye cream, it carries actives that pair with what was delivered into the crescent. The polynucleotides and hyaluronic acid Dr Samantha layered hold longer when surface barrier care is consistent.
