How Rejuran Helps Acne Scars and Enlarged Pores

When navigating the advanced medical aesthetic options in South Korea, international patients are often surprised to learn that Rejuran Healer is a highly powerful tool for treating structural facial imperfections like indented acne scars and large, stretched-out pores.

While many people associate Rejuran primarily with general anti-aging and hydration, its deep tissue-regeneration properties make it an exceptional clinical solution for smoothing out complex skin texturing.

The Root Cause: Why Scars and Large Pores Persist

To understand why Rejuran is so effective, it helps to look at what is happening beneath the skin surface:

• Atrophic Acne Scars: Boxcar, rolling, and icepick scars form because chronic inflammation from severe acne destroys the underlying collagen network. As the area heals, tough, fibrous bands pull the surface skin downward, creating permanent depressions and uneven shadows.
• Enlarged Pores: Pores generally expand for two reasons: excess sebum (oil) clogging the opening, or a loss of elasticity in the surrounding skin. When the dermal layers lose collagen, the walls supporting the pores weaken, causing them to stretch open and look noticeably larger.

How Rejuran Remodels the Skin Foundation

Rejuran is formulated with Polynucleotides (PN), which are highly purified DNA building blocks derived from salmon. When introduced into damaged dermal tissue, it initiates a comprehensive structural recovery process:

• Forcing New Collagen Synthesis: The salmon DNA molecules act as a biological scaffold. They activate specialized skin cells called fibroblasts, commanding them to continuously produce fresh, dense type-1 collagen. This new tissue slowly fills in indented acne scars from the bottom up, raising them to meet the surrounding skin level.
• Restoring Pore Support Walls: As fresh collagen and elastin fibers pack into the middle dermis, the structural walls surrounding your pores are reinforced. The skin firms up and snaps back into place, tightly squeezing the pore openings closed from the sides for a much smoother, airbrushed finish.
• Regulating Sebum Production: Rejuran fundamentally balances the skin's oil-to-water ratio. By providing deep, cellular hydration, it signals hyperactive sebaceous glands to slow down oil production, preventing the recurring blockages that keep pores stretched wide open.
• Accelerating Cellular Turn-Over: It triggers rapid cellular regeneration, helping the skin shed old, damaged scar tissue much faster while replacing it with smooth, evenly pigmented new cells.

Rejuran Healer vs. Rejuran S: Choosing Your Formula

When you book an appointment in Seoul for texturing issues, your dermatologist will likely select between two specific versions of the product:

• Rejuran Healer (Standard): This has a smooth, fluid viscosity designed for full-face application. It is highly effective for widespread texture issues, generalized skin thinning, and overall minimization of enlarged facial pores.
• Rejuran S (Specialized for Scars): This variant features a significantly higher viscosity and a thicker, concentrated gel structure. It is engineered specifically to be placed directly underneath deep, isolated acne scars. The thicker gel provides immediate physical lifting support to the depressed area while delivering a heavy concentration of PN to break up fibrous scar tissue.

The Seoul Secret: The Multi-Device Synergy Protocol

While Rejuran performs incredible work on its own, premier dermatology centers in neighborhoods like Gangnam and Hongdae achieve flawless results by creating combination treatments.

Because acne scars are held down by tough fibrous bands, doctors frequently pair Rejuran with energy-based devices:

• Subcision + Rejuran S: The doctor uses a tiny medical needle to physically slice the fibrous bands underneath deep rolling scars, releasing the tethered skin. They immediately inject Rejuran S into the empty space to act as a healing cushion, preventing the scar from re-tethering while fueling rapid collagen regrowth.
• Potenza RF Microneedling + Rejuran: Potenza uses insulated micro-needles to deliver radiofrequency heat deep into the skin, causing the dermal tissue to contract and tightening large pores. Rejuran is delivered simultaneously to drastically speed up healing, eliminate post-procedure redness, and supercharge the texture-smoothing results.

Estimated Costs in Seoul

• Rejuran S (For Targeted Scars, 1cc): ₩150,000 – ₩250,000 (Approx. $110 – $185 USD)
• Rejuran Healer (Full Face, 2cc): ₩250,000 – ₩400,000 (Approx. $185 – $295 USD)
• Synergy Combo (Potenza RF Microneedling + Rejuran 2cc): ₩450,000 – ₩750,000 (Approx. $330 – $550 USD)

Downtime and Expected Timeline

• Immediate Post-Care: You will experience visible "embossing" bumps at the micro-injection sites that look like tiny mosquito bites. These typically dissolve within 24 to 48 hours. Mild pinkness or pin-prick bruising around deep scar treatments can last for 3 to 5 days but can be safely covered with makeup after 24 hours.
• The Results Window: Because cellular remodeling requires time, changes do not happen overnight. You will notice a balancing of skin oil and early hydration within 1 to 2 weeks. Over the next 4 to 8 weeks, as fresh collagen matures, indented scars will progressively plump up and enlarged pores will visibly tighten.

Final Thoughts

If you are struggling with stubborn acne scars and enlarged pores that skincare products cannot seem to fix, Rejuran provides a highly scientific, permanent structural solution. By physically rebuilding the skin's broken internal support network and forcing fresh collagen production, it treats the literal root cause of texture imperfections. Whether used as a targeted scar treatment or paired with advanced energy devices in Seoul, investing in a Rejuran protocol is a phenomenal way to transition away from uneven texture and unlock a genuinely smooth, resilient complexion.
