Product Description

Rejuran I is a specialized skin booster for the delicate periorbital (eye) region that contains Polynucleotides (PN). In contrast to general boosters, it is designed especially for the thin and delicate skin surrounding the eyes, where early signs of aging - such as puffiness, dark circles, fine wrinkles, and skin laxity - often appear first. Formulated with highly purified salmon-derived DNA, it works by stimulating fibroblast activity, promoting collagen production, and enhancing the skin's natural regenerative processes.

Its low-viscosity texture allows for smooth and even distribution, making it ideal for thin and sensitive skin where traditional injectables may cause lumping or irregularities. Unlike traditional fillers, its effects are regenerative rather than volumizing, delivering natural, long-term improvement in skin quality.

The PN compounds in Rejuran I promote extracellular matrix regeneration and fibroblast activity, which boosts the production of collagen and elastin while repairing damaged tissue. It increases hydration, elasticity, and microcirculation, resulting in visible brightness, firmness, and a refreshed appearance.

Product Composition

Rejuran I is primarily composed of polynucleotides (PN). It contains 15 mg/mL of PN, which stimulates fibroblasts and regenerates injured skin tissue after injection.

Duration of Effect

After receiving Rejuran I treatment, results become apparent in two to four weeks. Over the next four to six weeks, tissue regeneration takes place, resulting in a gradual improvement that includes brightening and moisturizing effects.

Depending on lifestyle and skin condition, the results often last six to twelve months. A typical course comprises two to three sessions spaced three to four weeks apart, followed by maintenance treatments every six to nine months.

After Rejuran treatments, you can enjoy a variety of advantages, such as even skin tone and smoother skin texture, balanced levels of moisture and oil in the skin, and a decrease in fine wrinkles and pores.
