Rejuran i for dark circles: check your under-eye type first, then pick the treatment

Rejuran i, the eye-area formulation of polynucleotide, helps one kind of dark circle well: the kind caused by thin, crepey under-eye skin that lets the colour of vessels and muscle show through. Circles from a hollow tear trough or from pigment need a different approach. Sorting out which one you have is the first step at Barog in Seomyeon, Busan.

Three kinds of under-eye darkness

Thin-skin circles look bluish or purplish, and they often become more obvious with fatigue. The skin itself is fine and translucent, so what lies underneath shows through. Hollow circles are shadows: a groove below the eye catches less light, and the darkness shifts when you tilt your head under a lamp. Pigment circles are brownish and stay the same colour whatever the lighting.

Many people have a mix. A quick check is to gently stretch the skin under the eye: if the colour lightens, thin skin is playing a part. If the darkness moves with the light, a hollow is involved. If it stays brown, pigment is a factor.

Where Rejuran i fits among under-eye treatments

Rejuran i targets the thin-skin type. Polynucleotide supports repair in delicate skin, and over a course the under-eye area can become a little denser and smoother, so vessels show through less and fine crinkles soften. It does not add volume, so a deep tear trough will still cast a shadow.

For hollows, under-eye filler is the usual tool, placed carefully to avoid lumps or a bluish tint. For brown pigment, laser toning is the more fitting route. When circles combine causes, the consultation may sequence treatments, typically settling skin quality with PN first and assessing volume afterward.

How many Rejuran i sessions are usually needed

A polynucleotide course generally means three or four visits with a gap of three to four weeks between them, and the eye formulation follows the same logic of gradual change. The Barog board prices Rejuran i per session from ₩170,000 and also lists a five-session package for people who can attend regularly. The number right for you is set once your under-eye skin has been examined.

One session on a short trip can soften the look slightly, though the thin-skin type usually needs the full course to show a clear difference in daylight.

Bruising, swelling and who should skip Rejuran i

The skin under the eye is thin and rich in small vessels, so bruising is more likely here than on the cheeks. Plan for small bumps, pinpoint marks and possible swelling for one to three days, and allow extra time for a bruise to fade. Numbing cream is applied first, and the session takes around twenty to thirty minutes.

A fish or salmon allergy rules Rejuran i out, as do pregnancy, breastfeeding and infection or inflammation around the eye. Mention blood thinners, since they raise the chance of a visible bruise. The clinic sits in Seomyeon, Busan, near the subway, and weekday appointments run until 8pm, which helps if you want a quiet evening for any swelling to settle.

Does Rejuran i help under-eye dark circles?
It helps the thin-skin type, where bluish or purplish colour shows through translucent skin. Over a course, the skin can become denser so vessels show less. It does not fill hollows or remove brown pigment.
How many Rejuran eye sessions are usually needed?
A polynucleotide course generally runs three to four sessions, three to four weeks apart, and the eye formulation works gradually in the same way. The board also offers a five-session package; your number is set at consultation.
Is Rejuran i or under-eye filler better for my dark circles?
It depends on the cause. Hollow, shadowed circles usually respond to filler; thin, bluish skin responds to Rejuran i. If both apply, the consultation may plan the two in sequence.
Will Rejuran i make my under-eyes look puffy?
Small bumps and mild swelling are common for one to three days. After that, it does not add volume, so it should not create lasting puffiness.
Can Rejuran i be done on the upper eyelid area too?
The formulation is designed for the delicate skin around the eyes, and the treatment area is agreed at consultation after the injector examines your skin and lid structure.
