When winter comes, many people experience skin tightness and flaking.

Dry indoor air from heating, cold outdoor air, and frequent temperature changes quickly break down the skin barrier.

At times like this, many people focus on moisturizing by applying cream or oil over and over,

but even when the surface looks oily, the inside often remains dry, and this so-called “internal dryness” is not easily improved.

The key cause of internal dryness lies not on the skin’s surface, but in the dermal layer’s reduced ability to retain moisture and regenerate.

When collagen and elastic fibers in the skin decrease,

and the skin barrier function weakens,

even the most moisturizing products may not have enough power to hold moisture in.

For this reason, in winter, there is growing interest not just in simple moisturizing care,

but in procedures that enhance the skin’s own recovery ability,

and 대표적인 예가 바로 리쥬란과 쥬베룩입니다.

The representative examples are Rejuran and Juvelook.

What is Rejuran? A regenerative injection that helps the skin recover on its own

Rejuran is a skin regeneration injection based on PN (polynucleotide), a component extracted from salmon.

Because PN has a structure similar to human DNA,

it is less likely to trigger foreign-body reactions when injected into the skin, and it helps normalize a damaged skin environment.

The biggest feature of Rejuran is that, rather than immediately increasing volume,

it focuses on restoring the skin’s natural regenerative ability.

As time passes after the procedure, skin texture tends to become smoother,

fine lines are softened, and overall skin density and elasticity gradually improve.

In particular, for those whose skin becomes rough due to winter dryness

and whose makeup does not sit well,

it can help build a stronger skin foundation.

What is Juvelook? A skin booster that induces collagen production

Juvelook is a procedure that combines PLLA (polylactic acid) and hyaluronic acid,

with a focus on inducing collagen production within the skin.

Rather than simply filling in moisture,

it works by stimulating the skin to produce collagen on its own over time.

Juvelook is naturally absorbed into the skin,

and is characterized by gradually improving skin elasticity and thickness.

It is often considered especially when the skin becomes thinner and loses elasticity with age,

or when enlarged pores and fine lines are also a concern.

| Promotes collagen production | Improves skin elasticity and density | Softens fine lines and pores | Improves overall skin volume |

The maintenance period is relatively long, at around 9 to 12 months, and while the effects appear gradually, the duration tends to be good.

Rejuran vs. Juvelook: what is the difference?

Both procedures share the common goal of improving the skin’s internal environment, but their purposes and mechanisms differ.

Rejuran is strong at recovering and soothing damaged skin, so it is suitable when the skin is sensitive and dryness is severe. Juvelook aims to improve skin elasticity and structure through collagen production, so it is suitable when firmness loss and aging are the main concerns. In other words, if winter internal dryness has left the skin easily irritated and in poor condition, Rejuran may be a suitable option,

while if loss of skin volume and reduced elasticity are also concerns, Juvelook may be another option.

Depending on the case, the two procedures may also be performed together or in stages according to the skin condition.

For both Rejuran and Juvelook, the effects and level of satisfaction can vary depending on an individual’s skin condition, lifestyle, and degree of aging.

Immediately after the procedure, temporary swelling, embossing, or bruising may appear,

but in most cases, these improve naturally within a few days.

It is also important to determine the appropriate dosage and injection depth for the skin type through sufficient consultation.

Internal dryness in winter can accelerate skin aging if left untreated.

If you feel limited by simple moisturizing care,

considering a regenerative procedure that fills and supports the skin from within may be one way to pursue a more fundamental improvement.
