During the seasonal transition from autumn to winter, have you ever felt your pores look more noticeable in the mirror every morning?
You might think it’s because of increased sebum, but the real reason is “loss of skin elasticity.”
When temperature differences and dry air pull moisture out of the skin and damage collagen and elastin, the pore openings gradually widen.
Today, we’ll take a look at the causes of these changes and explore care routines focused on “lifting” and “pore tightening.”

Trend 1. Why Pores Enlarge During Seasonal Changes

Warm days and cold nights create daily temperature fluctuations that stress the skin.
As the air becomes dry and moisture evaporates, sebum production increases, creating an imbalance of “low moisture but excess oil.”
As a result, the skin loses elasticity, the dermal structure around the pores loosens, and the pores gradually expand.

In fact, 7 out of 10 people say “their pores enlarge during seasonal transitions,” and most recognize “elasticity care” as the key factor.

Now, pore reduction should be approached not as simple sebum control, but as a skin restoration process from within.

★ Morning & Evening Lifting Routine

• Morning Routine: Use a hydrating lifting serum + moisturizing cream; sunscreen is essential.
• Evening Routine: Apply peptide·retinol·EGF serum, then finish with a sleeping cream to create a protective layer.

TIP: When retinol·peptide products are used consistently for more than 8 weeks, studies have shown an average pore size reduction of 20–25%.

Trend 2. The Real Mechanism Behind Elasticity Loss and Enlarged Pores

Beneath the skin lie spring-like structures called collagen and elastin.
When these springs are healthy, they keep the pore openings tight, but when weakened by external irritation and dryness, their support decreases.
As a result, pores widen and the skin texture becomes uneven.

This is why, globally, collagen reset and structural skin restoration are now considered more important than mere “pore shrinking.”

★ Tightening Routine

• Moisturize within 30 seconds after cleansing: Apply moisturizer quickly while the skin is warm to prevent moisture loss.
• Astringent toner & cooling mask: Lowers skin temperature to prevent pore expansion and refine texture.
• Niacinamide + botanical ingredients: Helps regulate sebum and tighten the skin for smoother texture.

Using refrigerated toner pads for 5 minutes before makeup
provides an instant pore tightening effect.

Trend 3. Lifting + Pore Tightening Practical Guide

The key to pore care is consistent daily habits.
Maintain indoor humidity at 45–55%, and finish cleansing with lukewarm water instead of hot water.
If you gently massage upward for 3 minutes every morning and evening, blood circulation improves and elasticity is restored.

• ✅ Humidity Control: Keep indoor humidity at 45–55% to prevent moisture loss
• ✅ Water Temperature: Avoid hot water; use lukewarm water
• ✅ Light Massage: 3 minutes daily, lifting from bottom to top
• ✅ Sleep Routine: 7 hours of sleep to enhance skin recovery
• ✅ Nutrient Intake: Vitamin C, zinc, collagen peptides

According to Mintel 2025, 72% of global consumers answered,
“Daily routines are the key to pore management.”

Enlarged pores are not simply a sebum issue—they are the result of decreased skin elasticity.
This season, remember these three steps: 30-second moisture care after cleansing, consistent lifting routines, and control of skin temperature & humidity.
Small habits accumulate to restore skin elasticity.
This fall, awaken your skin’s hidden strength with “reset care,” not “wipe care.”
