"Age Shows on Your Neck"—REDNA's New Standards in "Neck-Specific" Anti-Aging Care

The common saying goes, "Age shows on your neck." Even if you appear younger thanks to makeup or skincare, aren’t there times when neck wrinkles spoil it all? For many, neck care is just an afterthought to skincare, and it’s often unclear what the correct routine is.

That's why this time, we interviewed Natural Science's REDNA, which offers the neck-exclusive cream, Bright Repair Neck Cream. We explored what the company considers the right neck care and delved deeply into the development background of the "Bright Repair Neck Cream."

REDNA is an anti-aging care line by Natural Science, a company with 30 years of expertise in caring for delicate skin. Addressing complex aging concerns that can’t be solved by gentle products alone, the brand proposes care rooted in the philosophy of “Hadaiku”—nurturing your skin’s natural potential.

"At our company, Natural Science, we promote 'Hadaiku' not just with REDNA but across other in-house brands, too. Hadaiku means supporting the skin’s natural abilities to maintain a healthy state. We value not only moisturizing and protecting but also restoring the skin’s inherent powers.

"Even in anti-aging care, including neck care, the fundamental first step is having a strong baseline of natural skin power. In recent years, the number of people with sensitive skin has risen, and it’s understood that cumulative low-level inflammation—like 'sometimes sensitive' or 'mildly sensitive'—can hasten aging.

"That’s precisely why, before starting aggressive anti-aging care, it’s important to restore the skin’s strength from its sensitive state."

So what was the background that led to the development of a specialized neck cream?

"The main trigger was strong demand from our employees. Many mentioned being concerned about their profile silhouette, and we often heard that they didn't know how to care for their necks.

"Once we decided to develop 'Bright Repair Neck Cream,' we first conducted a survey of actual users. This highlighted that the neck is an area where people easily notice aging but often neglect compared to the face. In terms of the number of concerns, neck wrinkles came right after nasolabial folds and eye wrinkles.

"Before working on the formula, we began by studying skin physiology, which revealed a difference in skin structure between the face and neck. The skin on the cheeks is about 1.7 millimeters thick, while the neck is thinner at 1.45 millimeters, making it more prone to external stimuli.

"Furthermore, the neck lacks ligaments connecting bone and dermis, which provide the kind of elasticity found in facial skin. Thus, neck skin moves more flexibly and sags more noticeably once it loosens. These facts made us realize that specialized neck care products are essential."

Are Neck Wrinkles Becoming Younger Due to “Smartphone Posture”? Causes & Bad Habits

With the widespread use of smartphones, more people are suffering from "smartphone neck" caused by prolonged improper posture. This so-called "smartphone neck" is now recognized as another factor that deepens neck wrinkles.

There seems to be a growing number of people concerned about neck wrinkles, regardless of age. In a survey conducted by our company, 61% of people in their 20s and 70% of people in their 30s reported having neck wrinkles. Data also shows that those who use their smartphones for more than three hours a day have significantly more concerns about neck wrinkles and sagging compared to those who do not.

The main cause of neck wrinkles and the so-called "smartphone neck" is tilting the head 30 degrees while using a smartphone. While the head typically weighs around 5kg when kept straight, tilting it 30 degrees places as much as 18kg of strain on the neck[1].

Maintaining the same posture for extended periods can cause the skin and muscles of the neck to contract and stiffen, eventually leading to wrinkles, pain, and other issues.

To prevent these concerns from getting worse, Komatsu emphasizes that it's essential not to keep your head down for long periods. When using a computer or smartphone, take regular breaks to stretch your neck, and try to hold your smartphone up to eye level.

Expert Tips: The Correct Way to Care for Your Neck

It's been said that overdoing care on the neck—which contains many nerves—can actually be counterproductive, but what exactly is the ideal way to care for your neck?

"The neck is a delicate area, so it's crucial to massage gently. Pressing too hard can strain the skin. Please massage gently to ease muscle tension.

"The neck is exposed all day long, making it prone to dryness and irritation. It's best to care for it twice a day—morning and night."

This is where you might want to try "Bright Repair Neck Cream." Unlike facial or body care creams, this product was developed with a formula dedicated specifically to neck care.

"In terms of ingredients, we focused on the basement membrane that connects the easily sagging layers of the epidermis and dermis on the neck, blending two types of peptides. We also included low-irritation retinol to help support skin elasticity.

"To ensure these ingredients reach the necessary areas, our company utilized our advanced lipocapsule technology, encapsulating the three key ingredients for neck care in multiple layers.

"Another unique feature is the addition of Ceracute®, a skin-lifting and moisturizing ingredient for instant results. This ceramide-mimicking component is rarely used in regular body creams.

"In addition, the cream contains fine powders that reflect light for a tone-up effect, helping your neck look brighter instantly after use.

"We've also developed a unique Moist Rich Smoothing formula specifically for "Bright Repair Neck Cream" to ensure a smooth, non-sticky feel while still delivering deep, rich moisture—a balance achieved through countless trials and ingredient adjustments."

Thanks to this formula, you get thorough hydration and elasticity for the skin without any stickiness, along with a texture that spreads easily for massages. You won't have to worry about your clothes sticking after applying it, and you'll stay comfortable even if you sweat while out and about.

The Importance of Preventive Care

According to fans of "Bright Repair Neck Cream," many have reported, "My neck looks brighter," "It's become smoother," and "My wrinkles became less noticeable after continued use."

"The neck, due to its structure, is one of the hardest areas to restore once it sags. That’s why it’s vital to start caring for your neck—even from your 20s—and to make a habit of gentle, age-appropriate neck care with dedicated creams, regardless of age.

"The formula is also alcohol-free, so you can use it after sun exposure as long as your skin isn’t irritated. Make neck care part of your daily beauty routine!"

"Bright Repair Neck Cream" was developed by Natural Science, utilizing their expert knowledge and focusing on the unique characteristics of neck skin. Whether you struggle with neck wrinkles or haven't started worrying about them yet, why not add neck care to your skincare routine?
