Do you ever feel that your face becomes especially tight and starts to flake as soon as the seasons change?
Many people find that their skin becomes more sensitive whenever the season changes.
When dry weather begins, your face may feel tight after washing in the morning,
and even the cosmetics you usually use may seem to absorb poorly.
No matter how much moisturizer you apply, by the afternoon your skin feels rough again, and your makeup starts to lift.
In fact, these symptoms are not just a surface issue; they are closely related to the skin’s internal structure,
and a decrease in collagen is one of the main causes.
Recently, the Rejiten procedure has been drawing attention in this context,
but how exactly can it help improve seasonal dryness?
Today, we will take a closer look at this.

Why do seasonal changes
make skin even drier?
When the seasons change, rapid temperature fluctuations and lower humidity weaken the skin’s protective barrier. In particular, from the mid-20s onward, collagen in the skin gradually begins to decrease due to external stressors and natural aging. As this happens, the dermis becomes thinner, elasticity declines, and the ability to retain moisture also weakens.
Collagen has the property of attracting moisture, filling the spaces between skin cells and helping retain moisture and nutrients. But when this component becomes insufficient, even if you apply moisturizer from the outside, it quickly evaporates.

What changes when dryness continues
- Reduced skin elasticity and fine lines
If dryness continues, tiny wrinkles begin to appear on the surface of the face. At first, they may show up as faint fine lines around the eyes or mouth, but over time they can deepen. This is not simply a matter of lacking moisture; it is a phenomenon that occurs as the skin’s internal structure itself weakens. In particular, seasonal changes make the external environment harsher, so symptoms often feel more severe than usual.
- Enlarged pores and rough skin texture
When collagen decreases, the skin loses its firmness, and pores also appear larger. In addition, the overall skin texture becomes rougher, makeup does not sit well, and the entire face may look dull. These changes are especially noticeable during dry seasons, which is why many people worry about them.

How does Rejiten work?
Rejiten is a skin booster that directly replenishes collagen in the skin tissue. Most collagen taken by mouth or applied topically is lost and difficult to deliver directly to the skin, but this procedure is characterized by directly injecting collagen peptides into the skin.
Collagen peptides have the same structure as the skin, so they can be used immediately as components needed for the regeneration of soft tissue. It also contains glycine, a protein that stabilizes collagen’s triple-helix structure and helps maintain firm, radiant skin.
This directly supplemented collagen works by drawing in moisture to keep the skin hydrated from within, while also helping regulate the oil-water balance and easing dryness. Especially when the external environment is difficult to manage, as in seasonal changes, an approach that improves the skin’s internal environment can be helpful.

If seasonal dryness is a concern,
how should you manage it?
- Management through direct collagen supplementation
If you are worried about dryness that recurs every season, you may want to consider a Rejiten procedure to directly replenish collagen in the skin. Since collagen attracts and retains moisture, directly supplementing it can help restore hydration from within.
In particular, if your skin feels dry again soon after applying moisturizer, you may need an approach that improves the skin’s internal environment rather than just surface care. Rejiten works by easing seasonal dryness through the moisture-retaining function of highly purified collagen and the regulation of the oil-water balance.
- Treatment cycle and management
In general, three treatments at 4-week intervals are often recommended. After the three sessions, additional treatments are typically done once every 6 to 12 months to maintain the effect. After the procedure, sufficient moisturizing care and sun protection are important, and paying attention to your daily lifestyle habits can also help the effect last longer.
Dryness caused by seasonal changes is a common concern for many people. If you accurately understand your skin condition and find the right care method, it can help you maintain a healthy skin environment even during seasonal changes. Of course, not everything can be improved by the procedure alone, so it is also important to remember that consistent self-care should be continued alongside treatment.
