Frequently Asked Questions

What type of dark circles do I have?

There are three main types: pigmentation (brown/tan discoloration from melanin), vascular (blue/purple from visible blood vessels through thin skin), and structural (shadows from hollows or eye bags). Many people have a combination. Dr. Kwang identifies your type during consultation and recommends targeted treatment.

Is under-eye filler safe?

Yes, when performed by an experienced injector using cannula technique. Dr. Kwang exclusively uses blunt-tipped cannulas for under-eye filler to minimize bruising and vascular complications. The product is placed in the correct tissue plane to avoid lumpiness or Tyndall effect (blue tint).

What is the difference between Rejuran-i and regular Rejuran?

Rejuran-i is a thinner formulation specifically designed for the delicate eye area. It has a lower viscosity than regular Rejuran Healer, allowing injection closer to the skin surface without lumpiness. It targets fine lines, crepiness, and dark circles around the eye.

What is Juvelook and how does it help dark circles?

Juvelook is a hybrid product combining polynucleotide (PN) with hyaluronic acid (HA). It provides both immediate hydration from HA and long-term skin regeneration from PN. For dark circles, it improves skin thickness, reduces transparency that reveals blood vessels, and stimulates collagen production.

How many sessions of Rejuran-i do I need?

Most patients see optimal results with 3-4 sessions spaced 2-4 weeks apart. Each session builds on the previous one, progressively thickening the skin and improving collagen quality. Maintenance sessions every 6-12 months help sustain results.

Can dark circles be completely eliminated?

This depends on the type. Structural hollows can be dramatically improved with filler. Vascular dark circles respond well to Rejuran-i and skin-thickening treatments. Pigmentation-type dark circles are the most challenging and may require a combination of treatments plus sun protection. Honest assessment is provided during consultation.

What is the downtime for under-eye treatments?

Filler: 2-3 days of mild swelling, possible bruising for 5-7 days (minimized by cannula technique). Rejuran-i: 1-2 days of tiny bumps at injection sites. Juvelook: similar to Rejuran-i with 1-2 days of minor swelling. All treatments allow return to work the next day with concealer.

How much do under-eye dark circle treatments cost in Bangkok?

Tear trough filler starts from 12,000 THB per syringe. Rejuran-i starts from 8,000 THB per session. Juvelook starts from 10,000 THB per session. These prices are typically 40-60% less than equivalent treatments in Western countries. Consultation is free. Contact LINE @verzo for exact quotes.
