REJURAN® vs. Aqua Injection: Which Is Better for Dry Skin?

In consultations, we often hear the question, "Does REJURAN® make the skin feel as instantly moisturized as Aqua Injection?" For immediate moisture and glow, hyaluronic acid-based Aqua Injection tends to be felt more quickly. Hyaluronic acid has the property of attracting a large amount of water per molecule, so many people feel their skin becoming moisturized right after injection, and improvements in texture and radiance begin to appear within about a week.

REJURAN® works by inducing regeneration, so rather than providing immediate hydration, it gradually improves skin quality over multiple sessions. Therefore, if you want to look moisturized and bright right away, Aqua Injection is more suitable. If you want to restore the skin itself even if it takes time, REJURAN® fits your goal. The moisturizing effect of Aqua Injection typically lasts for several weeks to several months as the hyaluronic acid is absorbed, and repeat treatments are needed.

For fundamental recovery such as skin texture, elasticity, and regeneration, the PN-based REJURAN® is more appropriate. REJURAN® stimulates fibroblasts to help repair damaged tissue and boost the skin's natural regenerative ability, which differs from Aqua Injection's focus on simply filling moisture.

In short, if dryness itself is an urgent concern, Aqua Injection is the choice. If dryness is linked to aging or loss of elasticity and you want to change skin quality, REJURAN® is more aligned with your goal. It is not a matter of which is better, but rather the answer depends on what your objective is.

Yes, if your goals involve both hydration and regeneration, combining them can be a complementary approach. Using Aqua Injection to provide immediate moisture and glow while using REJURAN® to work on texture and elasticity recovery can offer multi-faceted improvements compared to using only one treatment, and this is a commonly used strategy.

However, whether to receive them on the same day or to schedule them separately depends on your skin condition, recovery capacity, and budget. Since both treatments require repeat sessions, it is important to plan the overall schedule first rather than trying to do everything at once.

Both treatments involve multiple injections with fine needles, so some degree of stinging, temporary swelling, and marks can be common. Pain is usually managed with numbing cream, and redness or tiny bruises at the injection points typically subside within a few days.

The perceived difference varies depending on the ingredient, formulation, injection volume, and individual sensitivity, so it is difficult to say definitively that one is always more comfortable. If you are sensitive to pain or want to minimize downtime, you can inform your doctor during consultation so that adjustments can be made regarding anesthesia, injection technique, and aftercare. We recommend sharing your priorities with your specialist to plan accordingly.
