Hello.
This is Wells Dermatology.
With the peak summer vacation season just around the corner, the excitement is short-lived as more people are already visiting us with skin concerns caused by the sweltering heat and strong sunlight.

In summer, skin is exposed to sunburn and breakouts outdoors due to strong UV rays and high temperatures. Indoors, its moisture is stripped away by air conditioners running all day and the air from electric fans.

When the state of combination skin with an oily surface but dehydrated interior continues, the skin barrier breaks down, elasticity decreases, and aging accelerates rapidly.

Even if you apply sunscreen carefully and layer on moisturizer in your daily routine, skin that has already been damaged down to the dermis does not recover easily. When home care alone feels like trying to fill a bottomless jar, procedures such as Rejuran Healer, a skin booster that fundamentally enhances the skin’s natural restorative capacity, can be a good alternative.

Why Should Skin Boosters Reach the Dermis Directly?
No matter how beneficial the ingredients in cosmetics may be, they have difficulty passing through the outermost layer of the skin—the stratum corneum of the epidermis—and being absorbed deeply.
Skin boosters, on the other hand, are procedures that directly inject active ingredients that promote skin regeneration into the dermis, where the fundamental causes of aging and reduced elasticity lie. The term combines “Skin” with “Booster.”
Because they awaken the functions of skin cells from within, restore the oil-and-moisture balance, and induce collagen regeneration to remodel the skin’s structure itself in a healthier way, you can feel that your skin texture has become firmer.
An Upgrade That Reduces Pain: Rejuran HB PLUS
Rejuran Healer, considered the representative skin booster, is well known as a procedure that maximizes the skin’s regenerative capacity by using PN (Polynucleotide), a highly biocompatible ingredient extracted from salmon.
Although it improves the environment inside the skin and densely restores fine lines and skin texture, many people have hesitated to make a decision because of the characteristic pain experienced during the procedure.
Rejuran HB PLUS is the upgraded version developed to address these concerns about pain.
It contains lidocaine, a local anesthetic, in addition to the ingredients used in the original Rejuran Healer, reducing the pain felt during the procedure by approximately 50% or more. It also contains hyaluronic acid (HA), a powerful moisturizing agent, which provides a dewy moisturizing effect to dry skin alongside the regenerative effect.
A Checklist by Skin Type You Should Not Overlook
If you are experiencing any of the concerns below, it is advisable to check the condition of your dermis before this summer ends.
-
Those whose skin becomes easily dry and rough under air-conditioning during summer
-
Those whose skin is thin and lacks firmness, causing fine lines to become noticeable
-
Those concerned about a disrupted oil-and-moisture balance, with an oily surface and tightness underneath
-
Those who wanted the outstanding regenerative effects of Rejuran Healer but hesitated because they were afraid of the pain

Conclusion
Skin procedures depend on the practitioner’s skill in injecting the product evenly and accurately at the appropriate depth according to each patient’s skin thickness and degree of aging, just as much as they depend on simply injecting active ingredients.
If you would like to give tired and damaged skin a deep rest, consult thoroughly with a board-certified dermatologist with extensive clinical experience and begin a customized remodeling treatment suited precisely to your skin.
Thank you.
