Improving Skin Hydration and Tone with ELREJU Skin Booster: Key Considerations

By: Dr. Kim Han-gil, Chief Director of The Ippio Clinic


Growing Interest in Advanced Skin Boosters

As more patients seek treatments that address both skin brightening and regeneration at the same time, interest in skin booster procedures has become increasingly specialized. Within this trend, ELREJU, introduced as a next-generation skin booster, is gaining growing attention and utilization.


A promising newcomer that rivals Rejuran is making waves with its powerful hydrating ingredients, especially effective in harsh weather conditions.

Dual Benefits: Brightening and Tone Improvement

ELREJU is characterized by a carefully formulated combination of ingredients designed to enhance both skin hydration and tone improvement. It contains Tranexamic Acid and Glutathione, which help refine dull skin tone caused by pigmentation. As a result, it can reduce the appearance of melasma and dark spots, leading to a clearer, brighter overall complexion.

Designed for Faster Recovery and Comfort

One of the key considerations in skin booster treatments is the recovery process. Many dermatological procedures may cause temporary embossing effects or discomfort that interfere with daily activities. ELREJU is designed to minimize these post-treatment burdens, making it a suitable option for patients who wish to return to their daily routines quickly.


Unlike many dermatological procedures, ELREJU focuses on comfort and fast recovery.

Precision Delivery and Seasonal Skin Care Considerations

These benefits are closely related not only to the ingredients themselves but also to the delivery method. Recently, treatment design that ensures precise delivery of active ingredients into the skin has become increasingly important.
ELREJU features a fine, low-molecular structure and is optimally delivered into the dermal layer using specialized tips, helping to reduce pain, recovery time, and skin irritation while maximizing effectiveness.

Especially during winter, when the skin barrier weakens and dryness and sensitivity become more pronounced, a combined approach focusing on brightening, skin regeneration, and barrier repair becomes essential. Skin booster treatments containing PN and PDRN ingredients may serve as an effective option during this period.
However, beyond the benefits of the ingredients themselves, a customized treatment plan tailored to individual skin conditions and goals—developed through thorough consultation with medical professionals—is essential for optimal results.

Dr. Beau’s Note

Late winter is an ideal reset moment for the skin. Cold, dry air reveals the skin’s true needs hydration, repair, and balance making this season especially suitable for treatments focused on regeneration and tone correction. ELREJU works in harmony with this timing, supporting the skin’s natural recovery process rather than forcing dramatic change. By improving hydration, clarity, and texture with minimal stress, it helps the skin appear more defined and balanced—much like Seoul itself in late winter.
