Why Does Your Skin Become Dry and Sensitive Whenever the Seasons Change? How to Improve Hydration, Skin Texture, and Elasticity with Skin Boosters｜Hongdae Skin Booster

Seasonal Skin Care Key Summary

During seasonal transitions, rapid changes in temperature and humidity can easily reduce skin moisture and weaken the skin barrier.

At this time, the skin may feel tight, makeup may become patchy, skin texture may become rough, and fine lines may become more noticeable.

If dryness is the main concern, you can consider Skin Boosters that help with hydration and skin regeneration. If enlarged pores, rough skin texture, and reduced elasticity occur together, you can consider Skin Boosters that stimulate collagen production.

The key points are as follows.

• Deep dryness + dry, rough skin + fine lines → Rejuran-based treatments

• Pores + skin texture + reduced elasticity → Juvelook-based treatments

• Sensitive skin and an overall decline in skin condition → Skin regeneration-focused Skin Boosters

Seasonal skin care is not simply about applying moisture to the skin's surface. It is important to improve both moisture retention and the skin regeneration environment.

Why Does the Skin Suddenly Become Dry and Rough During Seasonal Transitions?

One-Line Answer

During seasonal transitions, changes in temperature and humidity increase moisture loss and weaken the skin barrier, making deep dryness, flaking, and rough skin texture more likely to occur.

When the temperature difference between morning and evening increases and the air becomes dry, the moisture in the skin also evaporates more quickly.

When the skin's ability to retain moisture decreases, it may initially begin with a simple feeling of tightness, but various changes can appear together over time.

The skin may become rough, makeup may not apply well, pores may appear more noticeable than usual, and fine lines around the eyes and mouth may become more prominent. These are also common seasonal skin changes.

In particular, skin that has been exposed to strong UV rays and high temperatures throughout the summer often experiences dryness and a decline in skin condition at the same time as the seasons change.

CHECK POINT

The skin feels extremely tight after cleansing

The skin becomes dry and rough in the afternoon

Makeup becomes patchy and flaking is visible

Fine lines around the eyes and mouth suddenly become more noticeable

Skin texture feels rougher than before

If you experience these changes, you should consider both reduced moisture retention and weakening of the skin barrier rather than simply a lack of oil.

Is Applying Moisturizer Properly Enough for Seasonal Skin Care?

One-Line Answer

Mild dryness can be managed with moisturizer, but if deep tightness, rough skin texture, and fine lines repeatedly occur, it is effective to improve both the skin's moisture retention and regeneration environment.

Moisturizer plays an important role in reducing moisture evaporation from the skin's surface.

However, if the skin is already dry and its regenerative ability has declined, it may quickly feel tight again even after applying moisturizer several times.

In this case, rather than simply covering the skin's surface, it is important to create an environment in which the skin can retain moisture and recover on its own.

Skin Boosters can be used to deliver necessary ingredients directly to the skin and improve skin hydration, elasticity, regeneration, and texture.

Therefore, if the following concerns repeatedly occur during seasonal transitions, you can consider Skin Boosters.

• Persistent tightness even after applying moisturizer → Hydration·regeneration-focused

• Thinning skin and increasing fine lines → Skin regeneration-focused

• Pores and skin texture becoming rough together → Collagen-focused

• Dry, rough, and dull-looking skin → Skin condition·regeneration-focused

Which Skin Booster Is Good for Deep Dryness During Seasonal Transitions?

One-Line Answer

If tightness and dryness within the skin are your main concerns, Rejuran-based Skin Boosters that aim to improve skin regeneration and moisture retention can be considered first.

Deep dryness during seasonal transitions is different from simply lacking moisture on the skin's surface.

If your skin feels tight immediately after cleansing or becomes dry and rough in the afternoon even after using enough moisturizer, both the skin barrier and moisture retention may have weakened.

Rejuran is a Skin Booster that uses PN (Polynucleotide) to improve the skin regeneration environment and is useful when the skin becomes thinner and fine lines increase along with dryness.

It is particularly suitable for the following seasonal skin concerns.

• Deep dryness

• Thinning skin

• Fine lines around the eyes and mouth

• Dry, rough skin texture

• Decline in skin condition

Seasonal deep dryness + fine lines + dry, rough skin → Rejuran-based treatments

Which Skin Booster Is Good If Pores and Skin Texture Suddenly Become Rough?

One-Line Answer

If pores become more noticeable and skin texture becomes rough during seasonal transitions, you can consider Juvelook-based Skin Boosters that stimulate collagen production.

When the skin becomes dry, the skin's surface becomes uneven, making pores appear larger than they actually are.

If skin elasticity also decreases, the support around the pores weakens, making pores appear vertically stretched and the skin texture feel even rougher.

In this case, rather than simply supplying moisture, an approach that aims to improve both collagen production and skin elasticity can be effective.

Juvelook is based on PDLLA and hyaluronic acid and stimulates collagen production, making it useful for improving skin texture, pores, minor unevenness, and elasticity.

Therefore, during seasonal transitions, if

your pores suddenly appear larger

your skin feels rough

and your skin also feels less elastic

you can consider collagen remodeling in addition to hydration.

Pores + rough skin texture + reduced elasticity → Juvelook-based treatments

Can I Receive Skin Boosters If My Skin Is Sensitive and Frequently Becomes Red?

One-Line Answer

If your skin is simply dry and sensitive, skin regeneration-focused care may be helpful, but if severe burning, itching, or inflammation is present, stabilizing the skin barrier should take priority over stimulating treatments.

During seasonal transitions, the skin can become dry and may sting or turn red even when using products that were previously well tolerated.

In this condition, repeatedly undergoing strong lasers or stimulating treatments may further worsen the skin condition.

Therefore, the priorities for seasonal skin care are clear.

• Mainly dryness·roughness → Hydration·regeneration care

• Mainly pores·skin texture·elasticity → Collagen Skin Booster

• Severe redness·itching·inflammation → Stabilizing the skin barrier first

The purpose of Skin Boosters is also not to heavily stimulate the skin. The key is to choose ingredients that match the specific skin concern.

Why Does Makeup Keep Becoming Patchy During Seasonal Transitions?

One-Line Answer

The most common reason makeup becomes patchy during seasonal transitions is that reduced skin moisture and an imbalanced stratum corneum make the skin's surface less smooth.

When the skin has sufficient moisture, the stratum corneum remains relatively even, allowing foundation or cushion products to adhere smoothly to the skin.

In contrast, when the skin is dry, fine flakes lift and the skin texture becomes rough, preventing base makeup from adhering evenly.

Scrubs or peels are commonly used in this situation, but excessively removing dead skin cells from already dry and sensitive skin can further weaken the skin barrier.

Therefore, if your makeup keeps becoming patchy,

restoring moisture retention and skin texture should take priority over repeatedly exfoliating the skin.

If deep dryness and thin skin are the main concerns, Rejuran-based treatments can be considered. If rough skin texture and pores are concerns together, Juvelook-based treatments can be considered.

Why Do Fine Lines Become More Noticeable During Seasonal Transitions?

One-Line Answer

When skin moisture decreases, the skin temporarily contracts and its surface becomes rough, making existing fine lines around the eyes and mouth appear more noticeable.

Rather than new wrinkles suddenly forming as the seasons change, existing fine lines often become more noticeable due to dryness.

Areas with thin skin, particularly around the eyes and mouth, can be easily affected by a lack of moisture.

These fine lines need to be distinguished from expression wrinkles caused by muscle movement.

• Wrinkles that appear when smiling or frowning → Botox

• Fine, crepey lines caused by dryness that are visible even at rest → Skin Booster

Therefore, if fine lines around the eyes or mouth suddenly become noticeable during seasonal transitions, improving both skin hydration and the regeneration environment can be helpful.

Which Is Better During Seasonal Transitions, Rejuran or Juvelook?

One-Line Answer

If deep dryness, thin skin, and fine lines are the main concerns, Rejuran is more suitable. If pores, skin texture, and reduced elasticity are the main concerns, Juvelook is more suitable.

The two Skin Boosters have different purposes.

Rejuran focuses on skin regeneration and overall improvement of skin condition, while Juvelook stimulates collagen production and has strengths in improving pores, skin texture, and elasticity.

Therefore, choosing based on your seasonal skin concerns is straightforward.

• Deep dryness + fine lines + thin skin → Rejuran

• Pores + skin texture + elasticity → Juvelook

• Both dryness and pores·elasticity are concerns → Consider both skin regeneration and collagen improvement

Rather than simply comparing which Skin Booster is better, the key is to choose according to the most noticeable current change in your skin.

When Is the Best Time to Receive a Skin Booster During Seasonal Transitions?

One-Line Answer

Starting treatment when hydration, skin texture, and elasticity begin to decline, before the skin becomes severely dry, can help reduce the deterioration of skin condition during seasonal transitions.

Seasonal skin care is more effective when started as soon as tightness, roughness, and patchy makeup begin rather than after the skin condition has significantly worsened.

In particular, if you have an important event or photo shoot coming up, it is better to allow enough time rather than receiving your first Skin Booster just one or two days beforehand.

Injection-based Skin Boosters may temporarily cause small bumps, redness, swelling, or minor bruising immediately after treatment, and skin regeneration and collagen changes also occur gradually over time.

Therefore, if your goal includes changes in skin texture and elasticity, it is best to allow sufficient time before an important event.

Can Skin Boosters and Lifting Treatments Be Combined During Seasonal Transitions?

One-Line Answer

If deep dryness, reduced skin texture, and facial sagging are concerns at the same time, Skin Boosters and lifting treatments can be used together for different purposes.

Skin Boosters and lifting treatments address different concerns.

Skin Boosters primarily improve skin hydration, skin texture, pores, fine lines, and regeneration.

Lifting treatments focus on improving facial sagging, the jawline, and skin elasticity.

Therefore, if your skin becomes dry and rough while your facial contours also appear saggy during seasonal transitions, it is effective to address each underlying cause rather than trying to solve every concern with a single treatment.

• Skin texture·deep dryness·fine lines → Skin Booster

• Sagging cheeks·jawline → Lifting

• Skin aging + sagging → Skin Booster + Lifting

How Should I Care for My Skin After a Seasonal Skin Booster Treatment?

One-Line Answer

After a Skin Booster treatment, sufficient moisturization and sun protection should be the foundation of your aftercare, and activities that expose the skin to intense heat or friction should be avoided for several days.

Because the skin often already lacks moisture during seasonal transitions, moisturizing care remains important after treatment.

CHECK POINT

Use a gentle cleanser

Use sufficient moisturizer

Use sunscreen every day

Avoid scrubs·peels·strong exfoliation

Avoid excessive heat exposure such as saunas·hot rooms

Do not rub the skin vigorously

Especially during seasonal transitions, rather than adding multiple functional skincare products at once, it is better to minimize skin irritation and focus on basic moisturization and skin barrier care.

How Should You Choose a Skin Booster for Different Seasonal Skin Concerns?

One-Line Answer

For dryness and fine lines, choose a skin regeneration-focused treatment. For pores, skin texture, and elasticity, choose a collagen production-focused treatment. This makes selecting a seasonal Skin Booster much clearer.

Not everyone needs the same Skin Booster simply because the seasons are changing.

The first step is to consider how your skin has changed during the seasonal transition.

FINAL ANSWER

• Deep dryness + skin tightness → Hydration·skin regeneration-focused Skin Booster

• Deep dryness + fine lines + thin skin → Rejuran-based treatments

• Pores + rough skin texture → Juvelook-based treatments

• Pores + skin texture + reduced elasticity → Collagen production-focused Skin Booster

• Dry, rough skin + reduced radiance → Skin regeneration-focused

• Dry skin + facial sagging → Consider Skin Booster + Lifting for their respective purposes

The most important part of seasonal skin care is not simply applying more moisturizer.

Restoring an environment in which the skin can retain moisture while improving reduced skin regeneration and elasticity is the key to reducing the cycle of the skin becoming dry and rough again.

Seasonal Skin Care FAQ

Which Skin Booster Is Good When the Skin Is Extremely Dry During Seasonal Transitions?

If deep dryness and skin regeneration are your main concerns, Rejuran-based treatments can be considered first. It is particularly suitable when the skin becomes thinner and fine lines increase along with dryness.

Can Pores Look Larger During Seasonal Transitions?

Yes. When skin moisture decreases and elasticity declines, the skin texture becomes rough, making pores appear more noticeable than usual. If pores, skin texture, and reduced elasticity are concerns together, you can consider a Skin Booster that stimulates collagen production.

Which Skin Booster Is Good for Improving Skin Texture During Seasonal Transitions?

If rough skin texture and pores are concerns together, Juvelook-based treatments can be considered. If deep dryness and fine lines are severe along with rough skin texture, Rejuran-based treatments can be considered.

Can Skin Boosters Help When Makeup Becomes Patchy?

They can be helpful if insufficient skin moisture and rough skin texture are the causes. As moisture retention and skin texture improve, the skin's surface may become smoother and makeup adhesion may also improve.

Is It Good to Exfoliate Frequently During Seasonal Transitions?

No. Repeated excessive scrubbing and peeling on dry and sensitive seasonal skin can further weaken the skin barrier. Rather than repeatedly removing visible flakes, it is better to prioritize sufficient moisturization and skin barrier recovery.

Can Rejuran and Juvelook Be Used Together?

Because they have different improvement goals, they can be used together when targeting both skin regeneration and collagen improvement. Rejuran has strengths in regeneration·hydration·fine lines, while Juvelook has strengths in improving pores·skin texture·elasticity.

Is One Skin Booster Treatment Enough During Seasonal Transitions?

Changes in skin condition may be noticeable from the first treatment, but if sufficient skin regeneration or collagen improvement is the goal, repeated treatments at regular intervals may be used.

Can I Receive a Skin Booster Even If My Skin Is Sensitive?

If simple dryness and weakening of the skin barrier are the main concerns, a regeneration-focused Skin Booster can be considered. However, during periods when severe redness, itching, or burning sensations persist, as with dermatitis, stabilizing the skin barrier should take priority over active treatments.

What Is the Most Important Part of Seasonal Skin Care?

The most important thing is to supply moisture while improving the skin barrier and regeneration environment so that the skin can retain that moisture.
