Kumho-dong Dermatology: The Importance of the Skin Barrier in Summer—Start Managing It in Advance with Rejuran and Juvelook!

Strengthen the skin barrier before summer

Hello, this is Raon Dermatology in Kumho-dong!

As midday temperatures rise sharply, more and more people are worrying about their skin health for the coming summer. Strong sunlight and humid air are factors that can easily weaken the skin’s external protective barrier and make it more sensitive! Before the full heat of summer begins, building up the skin’s internal resilience is not optional—it is essential. Ahead of the season when sweat and sebum production become more active, you should prepare your skin environment in advance to maintain a healthy condition that will not be thrown off by seasonal changes :)

The importance of the skin barrier in summer

The skin barrier we commonly refer to plays the role of blocking external irritation. In summer, intense ultraviolet rays directly damage this structure, stripping away internal moisture and compromising elasticity! As temperatures rise, the skin temperature rises as well, making inflammatory responses more likely and rapidly reducing protective function.

Air-conditioning used indoors also dries out the air and becomes a major culprit in disrupting the skin’s oil-water balance! When the skin is repeatedly exposed to extreme temperature differences between indoors and outdoors, blood vessels dilate and sensitivity increases, which can even lead to chronic facial redness~ To prevent these complex problems, active care that strengthens the barrier from within should be done in parallel. Let’s look at specific management methods from the next slide onward.

Ellavie Rejuto

First, Ellavie Rejuto is a method that increases the skin’s self-recovery ability by supplying the key substances that make up the dermis. Its main ingredient, ECM, stands for extracellular matrix and plays a core role in supporting the skin structure! Rejuto focuses on creating an internal environment that allows the skin to maintain its health on its own. When the dermal environment improves, the skin becomes better able to withstand external irritation, so sensitivity naturally decreases!

In addition, you can expect an effect that strengthens the skin’s thickness and density itself. Thin, sensitive skin types can easily have irritation transmitted all the way to the dermis even from minor刺激, and Rejuto helps supplement this structural weakness! As the thinned skin layer becomes thicker, moisture retention improves and elasticity recovers, helping the skin regain a smoother texture. It may help to understand this as a process of building real, practical basic skin strength :)

• Reinforces reduced skin thickness and density

• Restores the health of the skin’s internal environment

• Improves natural elasticity and skin texture

Rejuran HB Plus

Rejuran HB Plus is a formulation that adds moisturizing ingredients and a local anesthetic to the existing regenerative ingredients. The PN ingredient, a regenerative substance extracted from salmon, helps repair damaged skin from within, while the HA ingredient supplies moisture to address dryness! Many people with sensitive skin worry about pain during treatment, but Rejuran HB Plus contains lidocaine, so it can be received with much greater comfort than before.

It is especially worth noting the interaction in which the PN ingredient induces skin regeneration while the HA ingredient helps soothe irritation. You can understand this as the skin regenerating, inflammatory responses easing, and the weakened skin barrier structure being rebuilt! If you want to provide both abundant hydration and regenerative support to sensitive skin types struggling with repeated breakouts and redness, Rejuran HB Plus can be an efficient alternative :)

• Normalizes the disrupted skin regeneration cycle

• Regulates the oil-water balance and resolves dryness

• Eases redness caused by a weakened barrier

Juvelook

Lastly, Juvelook is a collagen booster with porous particles that induce the skin to produce its own collagen. The ingredient injected into the skin stimulates fibroblasts, helping them generate the skin’s natural elasticity substance! Rather than simply filling in with external material, it promotes structural improvement from within the skin, which is why the changes can feel more natural over time.

In particular, it shows excellent performance in reducing enlarged pores and refining fine lines, helping to smooth overall skin texture. The newly formed collagen tissue within the skin plays a role in firmly supporting skin that has loosened due to summer heat! For those who want to strengthen the foundation of their skin from a long-term perspective, care with Juvelook can be a positive direction :)

• Improves enlarged pores and fine lines

• Refines skin texture and contour

• Strengthens long-term skin structure

A selection guide for healthy skin

The last point I want to emphasize is that you should choose the care method most suitable for your skin condition. Since everyone has different skin thickness, sensitivity, and concerns, a customized prescription is more important than a one-size-fits-all approach! If your skin is thin and lacks firmness, consider Rejuto; if dryness and damage are severe, consider Rejuran; and if your goal is texture improvement, Juvelook may be the more efficient option.

After receiving the proper care, don’t forget post-care to maintain the results through sun protection and sufficient moisturizing, right~? If you want to keep your skin healthy and glowing even in the summer heat, please start preparing step by step from now. If you have any other questions, we recommend checking the method that suits you best through a consultation at any time!
