Unlike fillers that simply fill, the key is to build up the skin's natural fundamental strength.

Hello. This is Kim Young-gyun, CEO and Director of Core Dermatology. 🙂

From my time as a fellow at Hanyang University to the present, I've encountered countless patients, and there's one thing I hear very often in my office.

“Director, every time I look in the mirror, my face doesn't look like it used to. My skin has lost elasticity and my makeup always cakes up... What on earth should I do to improve it?”

Patients who actually visit our Core Dermatology Clinic are, day by day, Dry and weakening skineven as you feel..., “I'm worried my face will look unnatural or be ruined after the procedure.”You worry about that the most.

To those who express this feeling of helplessness and fear, we build the fundamental strength of your skin without exaggeration. Rejuran injectionI recommend this first.

Today, I directly confirmed in the clinical setting that patients feel most strongly ‘4 Key Effects of Real Rejuran Injections’And as a doctor, I must point out ‘An inconvenient truth’We will delve into everything.

Rejuran injections: eraser for fine lines and micro-wrinkles?!

Rejuran injectionThe key is that it's not just a ‘filler' to fill hollow cheeks.

through polynucleotide (PN) ingredients extracted from salmon Principle of maximizing the skin's own regenerative capacityYes.

This PN ingredient penetrates the damaged dermal layer, awakens dormant ‘fibroblasts,' and promotes the production of collagen and elastin. Simultaneously, it repairs the extracellular matrix (ECM), firming and tidying the collapsed skin structure.

A woman concerned about skin aging while looking in the mirror, noticing fine wrinkles around her eyes and mouth, and makeup settling into lines (effects of Rejuran injections)

As a result, rather than very deep wrinkles, Fine lines and wrinkles around the eyes (crow's feet), mouth, and cheeks.It gradually becomes shallower. In the patients“ own words, they feel a ”tightening sensation" in their skin.

Numerous studies have reported significant improvements in wrinkle depth, skin elasticity, and surface roughness in actual clinical trials. The reduction in minor unevenness that causes makeup to cake and fine wrinkles on the cheeks, in particular, is highly noticeable.

However, it's not a magical transformation immediately after the procedure. When you undergo the procedure more than twice, over a period of 3 to 4 weeks or more, “The difference is obvious even in the photo” You can expect change.

2. Sagging facial contours? Relieve skin elasticity and mild to early sagging

As we age, it's not just the amount of collagen that decreases.

Remaining collagen ‘The collapse of ‘quality’ and "array" themselvesThis is a real problem. Rejuran's role is to reorganize this messy structure.

The PN component that penetrates the dermis promotes cell division and ECM (extracellular matrix) remodeling, reorganizing the loose and sagging collagen network to be denser and firmer. Through this process, skin elasticity and firmness are noticeably improved.

A woman in her 30s, realizing the early signs of skin laxity and facial sagging, gently lifts her jawline and cheeks with her fingertips.

Objective measurement instruments in actual studies have also reported a tendency for elastic recovery to increase. Patients come to the clinic “Director, my cheeks look less saggy,” and “My neck and jawline look less wrinkled.”She rejoices, saying.

However, there's a point I absolutely must address here.

This procedure is not one that physically pulls up sagging skin, such as a facelift or thread lift. A regenerative treatment that alleviates early or mild sagging from the perspective of ‘elasticity recovery."You will get the highest satisfaction by approaching it this way.

3. The magic of makeup that adheres flawlessly! Improves skin texture, hydration, and radiance

In reality, the part that patients first and most broadly experience in the examination room is Skin texture, moisture, and subtle radiance.

It simultaneously repairs the damaged stratum corneum and dermis of the skin, strengthening the skin barrier function and dramatically boosting its moisture retention capacity. The skin itself becomes intrinsically less dry, transforming from a rough, sandpaper-like surface to one that is silky smooth.

in clinical data Moisture content, elasticity, surface roughness, skin brightness It is consistently confirmed that several items, including [item 1], [item 2], and [item 3], improve simultaneously.

  1. The fine irregularities between pores are smoothly organized Foundation will settle less in pores.
  2. Inner dryness of the skin is resolved, so even after washing my face It stays moisturizing for a long time without feeling tight.
  3. It returns a uniform gloss to the skin's surface, so you don't need to wear heavy makeup. “Glowy skin” Change happens.

[Director's Real Experience]

“When I had this procedure done on my own face, honestly, the pain was ‘enough to make tears well up.” It's due to its unique viscosity. But after a week, when I feel the smooth texture on my fingertips while washing my face, I forget the pain and find myself lying down on the bed again."

4. Savior for Damaged Skin! Acne Scar and Photoaging Repair

Acne scars and photoaging due to UV rays are both “A severely damaged dermal structure.”There is a decisive commonality.

When PN is injected into such a barren, damaged area Intensely promotes collagen regeneration and tissue remodelingAges to naturally fill in sunken areas and neaten sagging, damaged parts. It's especially effective in improving skin quality for shallow rolling scars, atrophic scars, and photoaging skin with a combination of uneven tone.

A woman closely observing her reflection in the mirror, concerned about uneven skin texture from acne scars and UV photodamage, as well as minor pigmentation.

Especially Skin characteristics of Koreans prone to hyperpigmentationIf you insist on strong lasers to fix blemishes, scars, or aging, you are more likely to experience side effects such as post-inflammatory hyperpigmentation (PIH), which can darken melasma and freckles. In this case, Rejuran injectionWhen used in conjunction with lasers, it creates the best synergy by strengthening the dermis, preventing laser side effects, reducing downtime such as redness or scabs, and dramatically increasing the speed of regeneration.

Core Dermatology's Honest Advice: The Uncomfortable Truth About Rejuran Injections

If I only tell you the advantages, I'm not a real doctor. This procedure isn't a cure-all either. If you fall into any of the categories below, you should reconsider the procedure.

  • For those whose jawline has already severely sagging: Surgical lifting or thread lifting should be the primary treatment. It is difficult to expect a dramatic improvement in sagging with Rejuran alone.
  • Someone extremely sensitive to pain: Even if the effects are good, the injection pain is quite significant. If you're too afraid of the pain, you should consider needle-free procedures or sedation. (Learn more about Rejuran pain)
  • Realistic side effects: Swelling and bruising: The ‘embossing’ phenomenon, where the skin becomes raised like mosquito bites as the injection liquid is administered, lasts for about 2-3 days. Also, since it involves a needle procedure, minor bruising may occur. If you have an important photoshoot or event coming up, it's safest to schedule it at least 1-2 weeks in advance to allow for recovery.
