Dark circles are one of the most persistent cosmetic concerns — and one of the most difficult to treat. Countless people have tried every eye cream, concealer, and even laser treatment, only to find their dark circles stubbornly unchanged. The root cause? Dark circles are not a single entity — they must be classified and treated by type. There are three main categories: vascular (bluish/purple — thin under-eye skin revealing underlying vessels), pigmentary (brown — melanin deposition), and structural (tear trough shadowing from volume loss). Many people have mixed types. Rappoel Dermatology near Gangnam Station, Seoul, uses Rejuran Healer PDRN periocular injections to repair damaged micro-vessels at the source, accelerate pigment metabolism, and stimulate collagen production — achieving comprehensive dark circle improvement from within.
Precise Dark Circle Classification and Targeted Strategy
- Vascular type (50%+ of cases): Extremely thin under-eye skin (~0.5mm) reveals the color of underlying micro-vessels — appearing bluish or purplish. Causes include allergies (allergic rhinitis causing infraorbital venous congestion), sleep deprivation, and eye strain. Pinch test: gently stretch the under-eye skin outward — if color deepens or stays the same, it’s vascular
- Pigmentary type (~30%): Melanin deposition creates brown or tan discoloration. Causes include genetics (common in Asian populations), UV exposure, chronic eye rubbing (friction stimulates melanocytes), and incomplete makeup removal. Pinch test: if color doesn’t lighten when stretched, it’s pigmentary
- Structural type (~20%): Deep tear trough or protruding eye bags cast shadows below — this is a contour issue, not a true color problem. Visible best under overhead or side lighting. Structural dark circles require tear trough filler or surgical blepharoplasty
- Mixed type (most common): Two or more types coexist — vascular + pigmentary, or vascular + structural — requiring multi-level combined treatment
Why Rejuran PDRN Is Ideally Suited for Under-Eye Dark Circles
- PDRN repairs damaged micro-vessels: Polynucleotides derived from salmon DNA promote vascular endothelial growth factor (VEGF) release, accelerating micro-vascular repair — addressing the root cause of vascular dark circles (blood pooling from leaky capillaries)
- Anti-inflammatory and antioxidant: PDRN potently scavenges free radicals and suppresses chronic low-grade periocular inflammation (allergy and rubbing-induced cytokine accumulation), reducing post-inflammatory hyperpigmentation
- Accelerates melanin clearance: New healthy cells speed up epidermal turnover, helping metabolize melanin deposited in the basal layer and visibly lightening pigmentary dark circles
- Thickens dermis: PDRN stimulates fibroblast activity, increasing periocular dermal thickness and collagen density — making thin translucent under-eye skin thicker and better at concealing underlying vessels
- Micro-injury repair cascade: Thousands of microscopic channels created by ultra-fine 31G needles trigger the body’s self-repair cascade, holistically upgrading periocular skin quality
- Minimal vascular risk: Rejuran periocular injections use superficial intradermal micro-deposits (not intravascular) with ultra-fine needles, making vascular occlusion risk extremely low in this high-risk zone
Rappoel Rejuran Dark Circle Treatment Protocol
- Dark circle classification (15 min): Physician uses dermatoscopy and stretch test to determine type (vascular/pigmentary/structural/mixed), designs differentiated injection plan
- Anesthesia prep (20 min): Periocular skin is extremely sensitive — high-concentration topical numbing cream applied for 20-25 minutes
- PDRN intradermal injection (15-20 min): 31G micro-needle delivers 0.5-1.0ml Rejuran per under-eye via multiple intradermal injection points, covering the entire periocular discoloration zone
- Post-treatment care (10 min): Ice pack cooling to reduce immediate redness, repair serum application, detailed 3-day aftercare instructions
The recommended Rejuran dark circle protocol is 3 sessions (3-4 weeks apart), with results compounding to peak after the third session. Vascular types improve fastest (visible 1st session improvement), pigmentary types require concurrent sunscreen and tyrosinase-inhibiting skincare support. Rappoel Dermatology is a 3-minute walk from Gangnam Station Exit 10, offering English and Chinese consultation with board-certified Korean dermatologists.
Frequently Asked Questions
How many Rejuran sessions for visible dark circle improvement?
Vascular dark circles respond fastest — visible bluish tone reduction 1-2 weeks after the first session (micro-vessel repair + mild dermal thickening). Pigmentary types take longer — typically 2-3 cumulative sessions for visible brown lightening. Mixed types with structural tear trough component require concurrent HA tear trough filler. The complete protocol is 3 sessions (3-4 weeks apart); ~80-90% of clients report significant improvement after 3 sessions. Results last 6-12 months; maintenance every 6-8 months recommended.
Is Rejuran under-eye injection painful?
The periocular zone is among the body’s most sensitive areas, but Rejuran uses an ultra-fine 31G needle (3-4x thinner than a blood-draw needle) with micro-volume deposits (0.02-0.03ml per point) — sensation is a light prick, not pain. Rappoel applies high-concentration 5% lidocaine topical cream for 20-25 minutes. Most clients rate discomfort at 2-3 out of 10. Post-injection, 10-20 tiny papules (small bumps) appear and self-level within 1-2 hours.
Can I wear makeup after Rejuran eye treatment?
No makeup or eye cream for 24 hours post-treatment — thousands of micro-injection channels need time to close. Water-only face washing after 24 hours; gentle cleanser after 48 hours; resume daily skincare and light makeup (sunscreen, light concealer) after 72 hours. Avoid acid-based or retinol eye products for one week. Apply ice pack 2-3 times daily for 10 minutes each during the first 3 days to reduce swelling.
Which type of dark circle does Rejuran work best on?
Rejuran improves all three types, with different strengths: (1) Vascular — Rejuran’s strength zone! PDRN repairs micro-vessels + thickens dermis to conceal vessels — the most dramatic results; (2) Pigmentary — PDRN accelerates metabolism + anti-inflammatory effects — moderate-to-strong improvement, best paired with tranexamic acid or vitamin C skincare; (3) Structural — Rejuran’s filling capacity is limited; mild collagen stimulation provides modest tear trough improvement — must be combined with HA tear trough filler for definitive results. Mixed types require a customized protocol based on dominant classification.
How does Rejuran compare to eye creams for dark circles?
Fundamentally different mechanism and depth of action: (1) Eye creams — act at the stratum corneum and superficial epidermis only, cannot reach the dermis; negligible improvement for established dark circles (especially vascular and pigmentary); (2) Rejuran — PDRN molecules penetrate to the dermal level, directly targeting the root cause (micro-vessel repair, melanin metabolism, collagen neogenesis) — solving the problem from within, not masking it on the surface. Analogy: eye cream is like painting over a cracked wall; Rejuran is like injecting repair material into the wall to rebuild its structure. This is why many ‘eye cream collectors’ eventually switch to Rejuran.
