Every summer, the same story: you finish your morning skincare, and within an hour, your face is already getting shiny. Your T-zone pores look bigger by the minute, and by afternoon, your makeup starts lifting.
The core issue? Skin temperature.
When outside temperature rises, your skin's surface temperature rises with it—triggering a chain reaction of sebum overproduction, pore expansion, and inflammation. This guide breaks down how to actually lower skin temperature (not just create a "cool sensation") to fundamentally solve these problems, step by step.
1. Why Does Skin Temperature Rise in Summer?
What Makes Skin Temperature Rise
Direct sunlight – UV rays transfer heat directly to your skin surface
Body heat increase – Exercise and activity → heat radiates through your face
Indoor/outdoor temperature gap – Going between air-conditioned rooms and hot outdoors disrupts skin's temperature regulation
Mask wearing – Breath and friction raise the temperature inside masks by 2-3℃
What Happens When Skin Temperature Rises by Just 1-2℃
Sebaceous glands activate → Sebum production spikes → T-zone gets oily
Pores expand → Wider sebum drainage channels → More visible pores
Moisture evaporation accelerates → Oily surface but dehydrated underneath (double dryness)
Inflammatory response → Breakouts and redness worsen
Makeup breakdown → Foundation mixes with sebum, oxidizes, and lifts
Clinical Data: Daily Weekly's Coolasting Water Drizzle Cream has been clinically proven to lower skin temperature by an average of 6.17℃.
2. Problems Caused by High Skin Temperature (Enlarged Pores, Excess Sebum, Makeup Meltdown)
Problem 1: Excess Sebum Production
When skin temperature rises, sebaceous glands go into overdrive. That's why your clean T-zone turns into an oil slick within 2 hours.
Problem 2: Pore Expansion
Heat makes pores widen—a natural response to create more drainage pathways for sebum. The problem is, enlarged pores trap more oil and debris.
Problem 3: Makeup Breakdown
Most base makeup (foundation, cushion) uses oil or silicone bases. When skin temperature is high:
Oil components melt and spread
Mix with sebum and oxidize → Darkens and gets patchy
Meets sweat and separates → Lifts and cakes
In actual comparison tests, using Daily Weekly Cream before makeup vs. regular moisturizer shows noticeable difference in base staying power after 4-5 hours.
3. The Core Principle of Cooling Skincare (Lowering Temperature vs. Maintaining Moisture)
The False Cooling Trap: Menthol and Alcohol
Most "cooling" products on the market only provide a "cool sensation" using menthol or alcohol.
Menthol products:
Only stimulate cold receptors on skin surface → Actual temperature barely drops
Effect lasts 5-10 minutes
Can irritate sensitive skin
Alcohol products:
Evaporates for instant coolness → But takes moisture with it
Dryness triggers skin to produce more sebum as defense
Weakens skin barrier
3 Requirements for Real Cooling
① Actual Temperature Drop (Clinical Data)
Must use ingredients like Cooling Complex, Iceplant Extract—not menthol/alcohol—to actually lower skin surface temperature.
Verification method: Check for clinical data (e.g., Daily Weekly proves -6.17℃)
② Cooling Duration
Regular menthol products: 5-10 minutes
Daily Weekly Serum: 30+ minutes, reactivates when you sweat
③ Simultaneous Hydration Ingredients
If you only cool without hydrating, skin produces more sebum as a defense mechanism. Must include:
Hyaluronic Acid – Holds 1000x its weight in water
Panthenol (Provitamin B5) – Strengthens barrier + retains moisture
Ceramide – Forms barrier to prevent moisture loss
Daily Weekly's patented Hyal Tank™ uses encapsulation technology to enhance both absorption and duration of hyaluronic acid.
4. 3 Ingredients to Check When Choosing Cooling Products
✅ Ingredient 1: Real Temperature-Lowering Cooling Agents
Avoid: Menthol, alcohol (temporary coolness, causes dryness)
Choose: Cooling Complex, Iceplant Extract, Menthyl Lactate
Verification: Check product page for clinical data
✅ Ingredient 2: Hydration & Moisture-Retention
Hyaluronic Acid – Water-holding capacity
Glycerin – Attracts moisture
Panthenol (Provitamin B5) – Strengthens skin barrier
Patent technology: Encapsulation tech like Hyal Tank™ for extended duration
✅ Ingredient 3: Soothing Agents (Sensitive Skin Care)
Cica (Centella Asiatica) – Anti-inflammatory, skin regeneration
Allantoin – Exfoliation + soothing
Madecassoside – Calms redness and irritation
Free from: Parabens, artificial fragrances, artificial colors
FAQ: Will Cooling Products Dry Out My Skin?
Q1. Won't cooling products make my skin dry?
A. Menthol or alcohol-based products might. But products with hyaluronic acid, panthenol, and ceramide actually prevent moisture loss and avoid dryness. Daily Weekly Cream has clinical proof of 48-hour hydration.
Q2. Do I really need cream in summer?
A. Even oily skin can lack moisture. Skipping cream makes skin produce more sebum as defense. Choose a non-sticky, lightweight cream instead.
Q3. How long does the cooling effect last?
A. Varies by product. Menthol products last 5-10 minutes. Daily Weekly Serum lasts 30+ minutes and reactivates when you sweat.
Q4. Can sensitive skin use cooling products?
A. Avoid products with menthol or alcohol, which can irritate. Daily Weekly products are hypoallergenic-tested with soothing ingredients like cica and panthenol, suitable for sensitive skin.
Q5. Do I need cooling products if I sleep with AC on?
A. AC lowers room temperature but strips moisture from skin. Cooling products regulate skin's own temperature while hydrating, making them even more necessary in AC environments.
