Anyone interested in skincare has likely heard of 'Rejuran' and 'Skin Booster'.

Both Rejuran and Skin Booster treatments are widely known for restoring the skin's fundamental health or giving it a radiant, dewy appearance. Especially among women in their 20s to 50s, the desire for "youthful" and "clear" skin has significantly increased, leading to explosive demand for these procedures.

However, it's difficult to get accurate information just from Instagram reviews or promotional images. Many people want to understand these treatments based on scientific evidence and information recognized by dermatologists.

This article will explore the differences between Rejuran and Skin Booster injections, their scientifically proven effects on the skin, post-treatment changes, and potential side effects. It is based on medical literature and clinical data, aiming to deliver truthful and reliable information. Whether you're considering aesthetic procedures, have already undergone Rejuran or Skin Booster treatments and are curious about the effects, or are planning to try them soon, this article is structured to help. Let's now dive into the scientific mechanisms, differences, and pre-/post-treatment considerations for Rejuran and Skin Boosters.

Why does combining Rejuran with Skin Booster amplify skincare benefits?

Skincare is not just about moisturizing the surface. It includes delivering nutrients deep into the skin and promoting regeneration. Recently, the beauty industry has been paying increasing attention to using Rejuran in combination with skin booster ampoules.

Rejuran contains powerful regenerative ingredients, while Skin Booster ampoules provide intense hydration and moisture. When used together, they can maximize improvements in skin barrier strength, elasticity, and wrinkle reduction.

This synergy is scientifically backed. The main ingredient in Rejuran, Polynucleotide (PN), helps promote cell regeneration and repair skin structure. Meanwhile, Skin Booster ampoules contain hyaluronic acid and various moisturizing agents that help retain hydration within the skin. In essence, while Rejuran restores and strengthens the skin, the Skin Booster ampoule provides hydration to maintain the skin in optimal condition.

Scientific Effects of Rejuran on the Skin

Rejuran is well known for its regenerative properties. Its key ingredient, Polynucleotide (PN), is derived from salmon DNA and helps repair damaged skin cells and reduce inflammation. Through this process, it improves skin elasticity, reduces wrinkles, and supports skin regeneration and recovery.

• Cell Regeneration: PN activates fibroblasts in the skin, promoting the production of collagen and elastin, increasing skin density and elasticity.

• Strengthening the Skin Barrier: When the skin barrier is damaged, its ability to protect against external factors weakens. Rejuran helps restore the barrier, enhancing resistance to external stimuli.

• Antioxidant and Anti-inflammatory Effects: PN reduces damage from free radicals and alleviates inflammation, helping to maintain healthy skin.

• Wrinkle Reduction and Elasticity: Rejuran works deep in the skin to smooth out wrinkles, especially fine lines and those around the eyes.

Scientific Effects of Skin Booster Ampoules on the Skin

Skin Booster ampoules offer immediate hydration and typically include ingredients such as hyaluronic acid, ceramides, and panthenol. Their primary function is to replenish moisture deep within the skin and maintain hydration levels.

• Deep Hydration: Hyaluronic acid can retain up to 1000 times its weight in water, deeply hydrating the skin.

• Preventing Moisture Loss: Ceramides reinforce the skin barrier, preventing water evaporation and keeping skin moist.

• Soothing and Anti-inflammatory: Panthenol and niacinamide calm and reduce skin inflammation, making them suitable for sensitive skin.
