Woman receiving Radiju skin booster treatment

Why is it still dry no matter how much you apply?

What is Rejutherapy?

It is Ulfit's unique procedure that uniformly delivers three premium ingredients—PDRN, Hyaluronic Acid, and Exosomes—to the papillary dermis, which cosmetics cannot reach, using lasers and ultrasound.

Eliminating the pain and bruising of manual injections, it penetrates accurately to an effective depth.

Fundamental Care

The Foundation of Healthy Skin, Moisture Balance

Restores the collapsed skin barrier and achieves a moisturizing feeling that fills from within.

Comparison between healthy skin and skin with broken moisture balance

Skin Barrier and Components

In healthy skin, the ceramide stratum corneum blocks external stimuli, and collagen, elastin, and hyaluronic acid in the dermis form a solid mesh structure.

Collagen Acts as the skin's pillar
Elastin The spring responsible for elasticity
Hyaluronic Acid The magnet that attracts moisture

Difference in Moisture Density

In a dermis lacking moisture, the collagen support collapses, causing wrinkles and loss of elasticity.

By injecting high-concentration hyaluronic acid directly into the dermis, it creates a moist and elastic skin environment as if it were holding water.

Regeneration

PDRN DNA fragment

A DNA fragment extracted from salmon testes, it is a tissue regeneration active substance most similar to human DNA. Beyond simple nutrient supply, it fundamentally restores damaged skin tissue.

Rapid Tissue Regeneration Effect

Wound recovery through FGF, EGF, and stimulation of cell differentiation

Anti-inflammatory Effect

Improvement of sensitive skin through cytokine regulation

Angiogenesis

Improvement of blood flow and complexion purification through VEGF, etc.

Mechanism of PDRN action

Next Generation Science

EXOSOME

The crystal that leads cell-to-cell communication, Exosome

Structure and effects of exosomes
01 Skin Tissue Regeneration
02 Immune Cell Activation
03 Anti-inflammatory & Anti-aging

By refining only the 0.1% core ingredients of the stem cell culture medium,
it delivers signals for skin cells to wake up on their own.

Manual Injection vs. Rejutherapy

Conventional Manual Injection

The depth is inconsistent, and pain, bruising, and swelling are likely to occur. There is a risk of the drug being injected too deeply or too shallowly.

Rejutherapy (Laser + Ultrasound)

Creates 0.06~0.4mm micro-holes with an Erbium-YAG laser to target the papillary dermis without pain. There is almost no downtime.

Q & A

Procedure Guide & FAQ

Radiju Skin Booster Procedure Information

The recommended number of sessions is 3-4, and it is most effective to proceed at 2-3 week intervals.

Since no needles are used, there is almost no pain (close to zero), and with minimal bruising or swelling, makeup is possible the next day.

It results in an increase in skin moisture (solving inner dryness), reduction of fine lines, improvement in elasticity, and a clearer skin texture and tone.
