Rejuran I


Those interested in skin injections are likely familiar with the popular Skin Booster, Rejuran. However, many may not know that Rejuran comes in several variants suitable for addressing different skin problems in various areas. In this article, Romrawin will introduce Rejuran I (Rejuran Eye), a Rejuran formulated for sensitive skin areas, and explain its advantages and how it differs from the regular Rejuran for facial injections.


What is Rejuran I?

Rejuran I is a product in the... Skin booster Or consider skincare products containing key ingredients like Polynucleotide (PN) extracted from salmon DNA, which is up to 98% similar to human DNA. Polynucleotides are a structural component of nucleic acids, also known as DNA and RNA, and have various functions such as aiding in new cell growth, stimulating collagen production, and promoting the release of growth factors. 

In the field of dermatology, the benefits of polynucleotides have been recognized, leading to their use as key ingredients in repairing skin cells damaged by various factors. This allows cells to function fully again. As a result of polynucleotide repair, skin cells can function normally, appearing firmer, radiant, hydrated, and glowing – overall, healthier-looking skin.


What causes dark circles under the eyes?

Rejuran helps reduce dark circles under the eyes.

Dark circles under the eyes are caused by poor blood circulation around the eyes, leading to the dilation of the veins under the eyes. Combined with the thinness of the skin in this area, this results in noticeable dark circles. There are several reasons for poor blood circulation, such as... 

  • Insufficient rest
  • Hormonal changes 
  • Exposure to sunlight causes increased accumulation of melanin pigment under the eyes.
  • In the event of an allergic reaction, or contact allergy, the body responds by releasing substances that cause blood vessels to dilate.
  • Other medical conditions may also cause dark circles under the eyes, such as thyroid disease.
  • Having a family history of dark circles under the eyes.

How Rejuran I works.

Skin Booster like Rejuran I contains key skin-nourishing ingredients such as Polynucleotide, an extract from salmon DNA. Polynucleotide has the property of repairing and regenerating skin cells that may be damaged by pollution, free radicals, and other factors that cause deterioration. This makes skin cells stronger and also stimulates the production of collagen and elastin, which are essential structural components of the skin. When the skin's structure is strong, the outer layer of the skin appears smoother, more elastic, and brighter. 

Furthermore, polynucleotides can stimulate the production of hyaluronic acid, helping the skin retain moisture better. This results in firmer, more hydrated skin, reducing the appearance of wrinkles. Therefore, injecting Rejuran under the eyes revitalizes the eye area, transforming wrinkled and dark circles into brighter, wrinkle-free eyes.

Why is Rejuran I suitable for under-eye injections?

The skin around the eyes is constantly moving; blinking alone is a very frequent movement, occurring an average of 10-15 times per minute. This causes the skin around the eyes to fold and wrinkle easily. Furthermore, the skin around the eyes is the most delicate on the body, making any procedures around the eyes require extra caution and safety precautions.

Therefore, procedures using Rejuran I, a product that gently revitalizes weakened skin cells to restore their strength, are safe. Because Rejuran I has a more liquid consistency than the regular formula, it can be safely injected around the eyes to address wrinkles or dark circles.
