Healthy Skin Care Through the Korean Sun Care Routine

BY 김민중

The Importance and Basic Principles of Sun Care

Sun care is more than just avoiding the sun in summer; it is the most fundamental skincare routine for preventing skin aging and maintaining a healthy skin barrier. In Korea, sunscreen is considered an essential final step of basic skincare rather than just a cosmetic, and it is a rule to apply it meticulously every morning before heading out. Choosing a product with broad-spectrum protection that blocks both UVA and UVB rays is the first step toward skin protection.

Understanding UV Protection Ratings

SPF (Sun Protection Factor): An index for blocking UVB; the higher the number, the longer the protection time.
PA (Protection grade of UVA): A rating for blocking UVA; the more '+' signs, the stronger the protection effect.

Daily Habits for Success

Sunscreen is most effective when applied in sufficient quantities 20 to 30 minutes before going outdoors. It is recommended to apply it thoroughly to areas easily exposed to UV rays, including the neck, behind the ears, and the back of the hands. Even if you are indoors, UV rays can enter through windows, so it is important to make it a habit to use sunscreen every morning after your basic skincare routine. Additionally, since the product can be removed by sweat or friction, it is recommended to reapply every 2 to 3 hours during outdoor activities.

Criteria for Choosing Sun Care Products by Skin Type

Selecting a sun care product tailored to your individual skin type is a key factor in preventing skin troubles and ensuring a satisfying experience. The Korean beauty market offers a wide range of choices, including physical sunscreens (inorganic), chemical sunscreens (organic), and hybrid sunscreens that combine the benefits of both. It is wise to first identify your skin concerns and consider the characteristics of the texture when choosing a product.

Choosing Texture Based on Skin Concerns

Oily Skin: Lightweight lotion types that reduce shine or products with a matte finish are suitable.
Dry Skin: Cream types containing moisturizing ingredients or essence-like textures with rich hydration are recommended.
Sensitive Skin: It is best to choose products with physical (inorganic) ingredients that minimize skin irritation and observe how your skin reacts.

Maintaining Proper Usage

Many people do not apply enough sunscreen to achieve full protective benefits. Generally, the standard amount to apply to the entire face is about the size of two finger lengths. Instead of applying a large amount at once, spreading it thinly in several layers can prevent pilling and allow the product to adhere better to the skin for a natural look. Especially if you are applying it before makeup, it is best to let it fully absorb into the skin before proceeding with base makeup.

The Perfect Cleansing Step After Sun Care

Because sun care products are designed to adhere closely to the skin to block UV rays, a thorough cleansing process after returning home is essential. If residue remains on the skin, it can clog pores and cause breakouts, so careful management through double cleansing is necessary. In particular, many recent sunscreens feature enhanced waterproof functions, requiring extra attention during cleansing.

Steps for Double Cleansing

Step 1: Use a cleansing oil or balm to first dissolve the oils in the sunscreen.
Step 2: Use a foam cleanser to gently wash away impurities and remaining residue from the skin surface.

Precautions When Cleansing

Scrubbing with excessive force can damage the skin barrier, so it is important to use lukewarm water and cleanse with a gentle massaging motion. Since the skin can become dry after cleansing, it is recommended to immediately supply moisture with a toner or essence to help soothe the skin. Exfoliating once or twice a week to normalize the skin turnover cycle can increase the absorption rate of sun care products and maintain a clearer complexion. Healthy skin begins with the harmony of proper protection and thorough cleansing.

Frequently Asked Questions

Should I apply sun care products every day?+

Sun care products are essential for skin health and should be used daily, regardless of whether you are indoors or outdoors. UV rays can penetrate clouds and pass through windows, and even visible light and indoor lighting can affect the skin. Therefore, making it a habit to apply sunscreen thoroughly as the last step of your morning skincare routine is the most effective way to prevent skin aging.

What is the difference between physical and chemical sunscreens?+

Physical sunscreens form a physical barrier on the skin's surface to reflect UV rays, while chemical sunscreens absorb UV rays and release them as heat. Physical sunscreens are recommended for sensitive skin as they cause less irritation but may leave a white cast. Chemical sunscreens spread well and have almost no white cast, but they may cause irritation depending on your skin type, so you should choose according to your own skin condition.

How can I effectively remove sun care products?+

Double cleansing is the most recommended method for effectively removing sun care products. First, use a cleansing oil or cleansing balm to sufficiently dissolve the oils in the sunscreen, then follow up with a foam cleanser to gently wash away remaining residue and impurities. This process helps maintain a clean complexion without clogging pores, which is highly effective in preventing breakouts.
