What Is a Skin Booster? SKINVIVE, REJURAN, Re2O

"What Is a Skin Booster?"

Even with a consistent skincare routine, the skin may continue to feel dehydrated,

rough, or prone to fine lines. This is often when people begin exploring skin booster treatments.

With options such as SKINVIVE, REJURAN, and Re2O available,

however, choosing the right product can feel confusing.

People searching 'what is skin booster' are often asking the same questions:

What is injected into the skin, and how does each product differ?

A skin booster is an injectable treatment that delivers active ingredients into the dermal layer

to support overall skin quality, including hydration, texture, elasticity, and the appearance of fine lines.

Unlike traditional fillers, which are commonly used to restore volume or shape facial contours,

skin boosters focus primarily on improving the condition and texture of the skin itself.

Each product contains different ingredients and serves a different purpose,

so treatment should begin with an assessment of what the skin currently needs.

Here, we compare SKINVIVE, REJURAN, REJURAN HB Plus, and Re2O

according to their key ingredients and treatment goals.

"SKINVIVE for Hydration

and Smoother-Looking Skin"

When the skin lacks moisture, it may appear rough,

makeup may sit unevenly, and fine lines can become more noticeable with facial movement.

SKINVIVE delivers hyaluronic acid into the skin and is used to

improve cheek smoothness while supporting a more hydrated appearance.

It may be considered for people whose main concerns are dryness,

rough texture, and a lack of radiance, or for those who want to

improve skin quality without significantly changing their facial contours.

Temporary redness, swelling, bruising, or small bumps may occur around the injection sites.

Recovery can vary depending on skin thickness, the amount injected, and the treatment area.

"What Is the Difference Between

REJURAN and REJURAN HB Plus?"

REJURAN is a PN-based injectable treatment used to support

the overall skin environment and manage concerns such as

fine lines, uneven texture, and reduced elasticity.

It may be considered when the skin feels thinner or more sensitive,

or when dryness and rough texture continue to return despite consistent skincare.

The increasingly searched REJURAN HB Plus combines PN with hyaluronic acid and lidocaine.

PN supports overall skin quality, hyaluronic acid provides additional hydration,

and lidocaine helps reduce discomfort during injection.

REJURAN Healer may be considered when texture, fine lines, and elasticity are the main concerns.

REJURAN HB Plus may suit patients who also want to address noticeable dehydration

while reducing the discomfort associated with treatment.

The decision should not be based on the product name alone.

Skin thickness, sensitivity, hydration levels,

and individual pain response should also guide the treatment plan.

"Re2O and the Skin’s Extracellular

Matrix Environment"

Re2O is a skin booster based on extracellular matrix,

or ECM, components surrounding the skin’s cells.

The ECM forms part of the structural environment in which skin cells reside.

It includes components such as collagen, elastin, hyaluronic acid, laminin,

fibronectin, and proteoglycans, which contribute to the skin’s structure and overall condition.

Rather than focusing on a single ingredient, Re2O takes a broader approach to

the environment that supports the skin.

It may be considered when several concerns appear together,

such as rough texture, reduced elasticity, dryness, or an imbalance in the skin’s oil and moisture levels.

"Choosing a Skin Booster

Based on Your Skin Concerns"

• SKINVIVE: A hyaluronic acid–based skin booster designed to improve

  hydration and promote smoother-looking skin.

• Rejuran: A PN-based treatment that supports the skin environment

  while addressing fine lines and loss of elasticity.

• Rejuran HB Plus: Helps improve overall skin condition

  and hydration while reducing discomfort during treatment.

• Re2O: An ECM-based skin booster that provides comprehensive care

  for skin texture, elasticity, and oil–moisture balance.

Even among people of the same age, skin thickness,

hydration levels, sensitivity, and the degree of elasticity loss can vary significantly.

If you are considering a skin booster treatment in Gangnam or near Sinnonhyeon,

begin by identifying which aspect of your skin needs the most attention.

Selecting the appropriate product, injection depth, dosage, and treatment area according to

your skin condition can help create a more natural and balanced result.
