In particular, the beauty device market continues to grow every year as external activities have decreased since COVID-19.

    However, there are so many types that I often get confused about which products fit my skin and purpose. In this article, I will compare and analyze major beauty devices such as LED masks, high-frequency devices, galvanics, and cleansing devices to help you choose the right one for you.

    The core engine of the beauty device should be selected according to the skin concern to increase the investment effect. We recommend high frequency/EMS if you need lifting, ultrasound/galvanic if you need moisture from the inside, and LED type if you want trouble care or soothing.

    The disadvantage: It gives heat to the skin, so the sensitive skin needs to be careful

    Recommended target: those in their 30s to 40s or older who need to improve elasticity, sagging skin, and wrinkles

    4. Galvanic vs Cleansing Device

    Galvanic

    Principle: Microcurrent penetrates the active ingredients deep into the skin

    Advantages: Maximize skin care product absorption

    Disadvantages: You can pay for using a dedicated gel

  • Watch Collector Introductory Guide ｜ How to collect a watch for the first time

    Watch Collector Introductory Guide ｜ How to collect a watch for the first time

    Watches have become more than just a time-checking tool, both a fashion item and an investment-worthy collection. More and more people, especially recently, are interested in investing in luxury watches and collecting watches, and a growing number of people are making watches a hobby of collecting them. So, how do beginners start collecting watches? Today, I’ll show you some basic guides for becoming a watch collector.

    the charm of collecting watches
    Collecting watches is not just a consumption, but a hobby that can enjoy cultural values and historical meanings together. Luxury watches also increase in value over time, as they contain longstanding craftsmanship and skills.

    Fashion Item: A watch alone will change your style.
    Value of Investment: Limited Edition, Popular Brand Watches May Increase In Price Over Time.
    Historical Meaning: An old vintage watch becomes a historical record in itself.
    What You Need to Know Before You Get a Clock Collection
    1. Clockwise: Mechanical vs Quartz

    Mechanical Clock (Automatic/Manual): Powered by springs and gears, it values sensitivity, brand philosophy and precision. It best reflects management, appreciation and collector tastes.
    Quartz Watch: Battery powered and timed more accurately. Practical and easy to manage, but emotional elements can be a bit weak.
    Your choice of introductory brands and models will depend on the values you value (emotional, management convenience, brand).

    watch collectors’ favorite brands
    In the introductory stage of watch collection, it is recommended to look at popular brands first.

    Rolex
    the world’s most popular luxury watch brand
    Recommended for investment due to high potential for value increase

    Omega (OMEGA)
    Swiss watch brand with both cost-effectiveness and historicity
    The speed master and the Sea Master line are famous

    Tag Heuer
    Popular for sports watches, and at a relatively reasonable price point
    Suitable as an introductory luxury watch

    Cartier
    It is also famous for its jewelry brand, but the watch design is also luxurious.
    Suitable for those who want fashion and collection at the same time

    Patek Philippe
    Called the pinnacle of high-end watches, it’s rare and valuable
    Recommended for experienced collectors rather than beginners

    First Step in Clock Collection: Buying & Managing Tips
    There are various purchasing methods such as official stores, used transactions, and overseas direct purchases. For beginners, it is recommended to use certified stores and official sales outlets.
    If it’s used and vintage, it’s essential to check the resell and authenticity by receiving ‘box, guarantee, and inspection history’ together.
    Storage/Management:
    Watchbox dedicated to watches, humidity and temperature maintenance, periodic management and overhaul (mechanical limited) are important.
    When not in use, use the enclosed case and watch winder when purchasing.
    Genuine Identification: Make sure to check the serial, marking, and status of the back case (back of the case) and dial (text plate). Vintage Seiko, Rolex, Omega, etc. may vary in value by several orders of magnitude depending on the serial number and the imprint standard.
    Clock storage and management
    The watch must be stored correctly to maintain its value.

    Watch Winder: useful for storing automatic watches
    Humidity and temperature management: dampness can damage internal parts.
    Regular inspection: Luxury watches must undergo an overhaul (precise inspection) every three to five years.
    Precautions when collecting watches
    Perfume Risk – The more famous brands, the more counterfeits there are. Make sure you use an official seller or a trusted second-hand platform.
    Trendy – Being popular in the short term doesn’t necessarily increase its value.
    Lack of liquidity – it may take some time to cash in your watch.
    Administrative costs – Additional costs may be incurred, such as overhaul and storage costs.
    Recommended tips for introducing a watch collector
    Start with reasonable brands such as Omega and Tag Heuer.
    If you look at limited edition models or special editions, there is a possibility of increasing their value.
    Build up your watch-related knowledge by referring to the online watch community, YouTube channels, and more.
    Remember that collection is not just a possession, but a process of enjoying history and culture.
    The Latest Trends Watch Collector Should Know (2025)
    Recell Market Revitalization: Popular models such as Rolex and Omega also have higher used prices than new ones, so you can seek value preservation or profit margins.
    Caution: Fake and illegal modification: The risk of counterfeiting is rapidly increasing in the used/overseas direct purchase market. Expert verification procedures and community utilization are required.
    Introductory community/review: Information collection and actual user sharing are activated in various cafes, clubs, and review forums.
    The philosophy of “the more you wear it, the more valuable it is”: watches sometimes accumulate in value as investments and daily companions.
    Conclusion Collecting ｜ watches is a hobby that grows with time
    Collecting watches is not just a luxury, but an investment hobby that grows in meaning and value over time. Rather than buying expensive watches in a hurry, it is better for beginners to gain experience by taking steps slowly with beginner brand → intermediate brand → high-end brand.

    The watch market is expected to become more active in the future. Based on your love and knowledge of watches, you will one day be able to complete your own special watch collection.

  • Self-branding strategy, how to create your own brand

    Self-branding strategy, how to create your own brand

    Recently, one of the most important keywords in the job market and business environment is self-branding. It has become an era where it is difficult to differentiate based on simply specifications or experience, and individuals need to brand their own values to be competitive. In this article, we will deal with the concept, necessity, specific strategies and practices of self-branding, and introduce how to effectively build your own brand.

    What is self-branding?
    Self-branding is the process of creating your own distinctive brand image based on your competencies, values, and experiences. Just as companies brand products and services, it is important for individuals to clearly convey their identity and expertise.

    In other words, self-branding is not just a “good look” but a strategic self-expression that effectively shows one’s strengths and story.

    Why Self-Branding Is Needed
    Securing competitiveness
    It is necessary to make yourself stand out in the fierce job and business market.
    building trust
    Steady branding can give others expertise and trust.
    creating opportunities
    Well-established personal brands lead to networking, collaboration, and new career opportunities.
    self-improvement
    The branding process itself is an opportunity to look back on yourself and grow.
    Self-Branding Strategy Step 6
    1. Self Analysis
    The first step in branding is to know yourself.

    What are my strengths and weaknesses?
    What field am I good at?
    What values do you want to convey to others?
    If we summarize this clearly, the future branding direction will be clear.

    2. Goal Setting
    The purpose of self-branding varies from person to person.

    employment and career development
    Acquire customers as freelancers
    Growth into SNS influencer
    building a reputation as a professional
    Your strategy will only materialize if your goals are clear.

    3. The Latest Self Branding Trends in 2025
    Revitalizing the content creator economy
    It is an era in which individual video, writing, and photography contents become brands. ‘I’ becomes the subject of the content, and everyday moments become brand stories.
    Persona-based branding emphasis
    A persona strategy that balances the real “I” and the brand “I” and shows a human side that can empathize with customers is important.
    Micro influencer collaboration increases
    There have been more cases of collaborating with microinfluencers who are stronger to a specific target group than a popular influencer. This ensures high reliability and effectiveness for the cost.
    Emphasis on brand ethics and social responsibility
    It is a time when ‘value-based’ branding, which includes ethical aspects such as environmental and social values, is more powerful.

    4. Storytelling
    Branding isn’t just a history listing, it’s storytelling.
    For example, the story of “designers who understand and design the emotions of users” is more convincing than “design majors.”

    When creating a story, consider the following.

    Why did you start this job?
    What is the only way I can do it?
    What values do they contain?
    5. Utilize online platforms
    In modern society, self-branding is completed online.

    Blog: Sharing professional writing and know-how
    SNS (Instagram, YouTube, TikTok, etc): Personal Branding Spreads
    LinkedIn: Global Networking and Career Portfolio Management
    Blogging, in particular, is a good means of showing expertise, as the search exposure effect is great through SEO optimization.

    6. Building Visual Identities
    Branding is also close to the image.

    Consistently use profile photos, logos, and color tones
    Business cards, portfolios, and SNS design are unified
    Consistency in writing style, speech and content topics
    These small parts come together to form a brand image.

    7. steady management and growth
    Branding requires continuous management, not one-off.

    Update content regularly
    Reflect on new experiences and achievements
    Improve your brand with feedback
    Branding builds trust and influence over time.

    Self-Branding Success Stories
    YouTubers and influencers: Branding Your Own Personality with Content
    Experts (doctors, lawyers, designers, etc): Share expertise through blogs and SNS → Get trust and customers
    Jobseekers: Portfolio Blog Speaks Strong Impression on Businesses through SNS Activities
    As such, self-branding can be applied to anyone regardless of their industry.

    Tips for practicing self-branding
    Break down your own area of expertise and concentrate
    It maximizes professionalism by specifying it like a ‘start-up SNS marketing expert’ rather than a ‘marketing expert’.
    Constantly creating and distributing content
    The key is to be constantly exposed through regular posting and video uploads. Make good use of the SEO keyword as well.
    Get feedback and improve
    Active communication with followers and subscribers and accepting feedback increases brand credibility.
    Personal website and blog operation
    Personal sites serving as digital portfolios are an important means of showing professionalism and authenticity.
    Expand networking and collaboration
    Interact with people from various fields, try collaborative projects, and raise awareness.
    Conclusion: Self-branding is an investment in myself
    Self-branding is an essential strategy for survival and growth for both individuals and single-person companies living in 2025. You can succeed only when you actively utilize SNS and digital channels with clear messages, consistent visuals, and content tailored to your target audience based on your authenticity. Build a strong personal brand with your strengths and individuality without missing out on changing consumption trends and digital environments.

    Constant self-care and communication will connect you to the opportunity you want. Start your own self-branding strategy today.

    Telemedicine has already become commonplace in many countries, including the United States, Japan, and Australia.

    In particular, platforms like Teladoc Health in the United States and Ping An Good Doctor in China have millions of users. These cases are expected to have a significant impact on the Korean telemedicine industry in the future.

    8. Future prospects for telemedicine services

    Telemedicine will be combined with AI diagnostic technology, wearable devices, and 5G and 6G communication networks to enable faster and more accurate treatment.

    In addition, when healthcare data is accumulated, preventive medical care and customized treatment are expected to begin in earnest.

    9. Precautions when using telemedicine services

    Use authorized platforms

    Check whether personal information is encrypted

    Accurate symptom delivery

    Face-to-face treatment if necessary after non-face-to-face treatment

    10. Wrap it up

    Telemedicine is an innovation that is changing the healthcare paradigm. It has advantages of convenience, accessibility, and efficiency, but it also remains challenging, such as security issues and diagnostic limitations.

    If the law and system improvement and technological development go hand in hand in hand, telemedicine will become an essential medical service that can be used safely and easily by the whole nation.

    Several preparations are needed for telemedicine services to spread further.

    First, the relevant legislation also needs to be overhauled. Second, we need to strengthen the technical infrastructure, and third, we need to educate medical staff and patients. This will make telemedicine services safer and more effective.

    Telemedicine services have great potential to revolutionize our healthcare. We look forward to future developments, and hope that access to healthcare services will be further improved.

  • EV vs Hybrid, which choice would be wiser?

    EV vs Hybrid, which choice would be wiser?

    The popularity of electric vehicles (EVs) and hybrid vehicles (HEVs) in the automobile market has been steadily increasing recently. Amid the trend of the automobile market shifting from internal combustion engines to eco-friendly vehicles, electric vehicles (EVs) and hybrid vehicles (HEVs) are the two options that receive the most attention. The combination of the government’s eco-friendly policies, fuel cost reduction, and technological advances has led consumers to think about eco-friendly vehicles instead of internal combustion engine vehicles.

    So which car should I choose, electric or hybrid? Both models are appealing to environmentally conscious consumers, but when you’re actually considering a purchase, you’ll need to carefully compare the pros and cons, cost, convenience, and maintenance costs of each model.

    1. Characteristics of Electric Vehicles (EVs)

    Electric cars are powered by 100% batteries and electric motors. It does not use fossil fuels such as gasoline or diesel and charges the battery from an external power source. The structure is simple because there are no internal combustion engine parts, and there are no emissions at all.

    Examples of typical electric vehicles: Tesla Model 3, Ioniq 5, Niro EV, and more.

    Advantages

    Weakness

    Zero carbon emissions: completely eco-friendly, futuristic.

    Lack of charging infrastructure: some areas, inconvenient when driving long distances.

    Low maintenance/operating costs: electricity rates are around 20-30% compared to petrol.

    Charging time: Fast charging also takes at least 30 minutes to an hour.

    Noise/vibration low: comfortable ride, suitable for urban & residential areas.

    Driving distance limit: Battery capacity limit, winter attenuation watch out.

    Strong acceleration and advanced features: Immediate torque, OTA function due to the nature of electric motors.

    High initial purchase cost: but can be offset by subsidies.

    Various government support, such as tax cuts and exclusive parking.

    Battery life, cost of replacement.

    2. Features of Hybrid (HEV)

    Hybrid cars are a combination of internal combustion engines (mainly gasoline engines) and electric motors. The battery mainly uses self-charging (rehabilitation braking, etc.) while driving, and external charging is possible for plug-in hybrid (PHEV).

    Examples of typical hybrid vehicles: Hyundai Sonata HEV, Toyota Prius, Kia Niro HEV, etc.

    Advantages

    Weakness

    High fuel economy: Best efficiency in the city with a combination of internal combustion engines and electric motors.

    Price burden: If it is about 4 to 6 million won more expensive than the internal combustion engine of the same class.

    No charging stress: Solved with a gas station.

    Reduced efficiency and reduced fuel economy differences when driving long distances and high speeds.

    Quiet and smooth ride, excellent initial acceleration responsiveness.

    Battery life limit, replacement and management required.

    Eco-friendly benefits (tax cuts, parking and toll discounts).

    Battery efficiency and fuel efficiency drop sharply in winter and mid-season.

    Reduce maintenance and maintenance costs (brake pads, etc.).

    Not suitable for motor size, power limit, and high performance due to the structure.

    3. What to consider when purchasing in real life

    Vehicle Price: Electric vehicles and hybrids both have higher initial prices than internal combustion engines, but you must check whether government subsidies/tax benefits (up to millions of won) are applied.

    Driving environment: Electric cars and hybrids are both advantageous if it’s mainly in the city center and commuting. Hybrid is more advantageous if you have a lot of local, long-distance, and high-speed driving.

    Charging environment: Electric vehicle merit if self-charging is easy in low floors of apartments or houses. Hybrid if charging infrastructure is weak or traveling/business trips are frequent.

    Car depreciation/balance: Electric cars tend to have greater residual value or depreciation than hybrid due to the emergence of new technologies and battery durability issues.

    4. environmental impact

    EV: Ultimately, “zero emissions” can be achieved, making it the most eco-friendly means of transportation when linked to the renewable energy mix.

    Hybrid: Transitional nature requiring parallelism with existing road infrastructure and internal combustion engines. However, it is popular as a short-term option due to its relatively high purchasing/maintenance convenience.

    5. Which car should I choose?

    EV Recommendation: Environmental issues, close proximity and regular pattern driving in the city, home rechargeable, and those who want to utilize the latest features.

    Hybrid recommendations: long-distance, high-speed driving, environment with insufficient charging infrastructure, fuel efficiency and fuel convenience, and low initial cost burden.

    Both are classified as eco-friendly cars and can receive various government support, subsidies, and tax benefits, so please compare them carefully according to your actual driving pattern, living environment, and budget to make the best choice.

    📌 Conclusion

    Electric cars and hybrids are both eco-friendly means of transportation, but the choice depends on your lifestyle and your local infrastructure.

    EVs are likely to be the center of future mobility, but hybrids will remain a stable transition option for the time being.

    Therefore, it is wise to carefully examine your driving habits, charging environment, and vehicle maintenance costs before purchasing.
