Shrinking large pores is harder than most people think. Most pore-minimizing products only temporarily reduce their appearance without addressing the root cause. This article covers everything you need to know: the real causes behind enlarged pores, daily home care, and the most effective large pores treatment currently available — Rejuran injection.
What Causes Large Pores?
Large pores are harder to fix than most creams suggest. Most pore minimizer products only temporarily tighten pores — they don't address the root cause. This guide covers everything: why pores enlarge, home care options, and the most effective large pores treatment today — Rejuran injection.
- Excess androgens stimulate the sebaceous glands to overproduce sebum, forcing pores to expand
- Accumulated buildup — when dirt and sebum accumulate over time, the pore walls are gradually stretched wider
- Collagen loss — skin that has lost elasticity can no longer maintain pores at their normal size
- Genetics — determines pore size from birth; cannot be permanently changed, but can be visibly minimized
Problems Caused by Large Pores
The problems go beyond visible pores — they also lead to:
- Oily skin and frequent breakouts, as enlarged pores collect more dirt
- Uneven makeup application — foundation doesn't adhere well and wears off faster than normal
- Dull, rough-looking skin — clearly visible in natural light and photography
- Fine lines around pores appear sooner as collagen depletes
What Are the Treatment Options for Large Pores?
At-Home Skincare
Cleanse thoroughly morning and night, use products containing niacinamide or retinol to tighten pores and control sebum. Avoid overly rich creams that may further clog pores. This approach brings moderate improvement but requires consistent long-term use.
Rejuran Injection Program
The fastest and most visible option. Rejuran injection restores skin structure from within using PN (polynucleotide), stimulating new collagen production and visibly tightening pores within 5–7 days.
How Does Rejuran Injection Treat Large Pores?
Rejuran is an innovation certified by both the Korean MFDS and Thai FDA, legally registered for import. Its core ingredient, PN (polynucleotide), is extracted from salmon DNA — the molecular structure most similar to human DNA.
Once injected into the skin layer, PN directly activates skin fibroblasts to produce new collagen and elastin. The results of Rejuran injection include:
- Visibly tightened, minimized pores
- Smooth, dewy glass-skin texture
- Acne scars and fine lines visibly reduced
- Stronger, more elastic skin from within
When Will You See Results? How Long Do They Last?
Skin feels noticeably smoother within 5–7 days after the first session. Results from a single session last approximately 2 months.
For best and longest-lasting results, doctors recommend 4 consecutive sessions spaced 3–4 weeks apart, allowing effects to last 6–8 months.
Is Rejuran Injection Safe? What Are the Side Effects?
Rejuran at MEGA CLINIC is certified by both Korean and Thai FDA, legally imported — not counterfeit or gray-market products.
Temporary side effects may include needle redness, slight bruising, and minor bumps at the injection site — all of which resolve on their own within a few days. Not dangerous, and other procedures can be done the same day.

FAQ: Common Questions About Large Pores and Rejuran Injection
Can Large Pores Be Permanently Eliminated?
Pores cannot be permanently eliminated as they are part of the skin's structure, but Rejuran injection stimulates collagen around the pores, making them visibly tighter and smaller — especially with 4 consecutive sessions.
How Is Rejuran Injection Different from a Chanel Injection?
Rejuran focuses on PN (polynucleotide) for cellular-level skin repair — ideal for large pores, acne scars, and damaged skin. Chanel injection (PDRN + HA) focuses on moisture and radiance. Both can be combined on the same day.
Does Rejuran Injection Hurt?
Very minimal discomfort — comparable to a routine blood draw. Numbing cream is applied beforehand. No pain during or after the injection; you can resume normal activities immediately.
Can Rejuran Be Combined with Other Treatments?
Yes. Rejuran can be combined with Botox, filler, or lifting devices on the same day. The doctor will plan the treatment order appropriately for each individual.
How Should You Care for Your Skin After Rejuran Injection?
Avoid direct sun, intense exercise, and dirty water for the first 24 hours. Apply sunscreen daily to maintain results. No downtime required — resume normal activities immediately after the session.
Can Rejuran Help with Genetically Large Pores?
Yes. Even though genetic structure cannot be changed, Rejuran injection stimulates collagen around the pores, making them visibly tighter and smaller — including in cases caused by genetics.
