All About Sun Care: Korean UV Protection Routines and Product Selection

BY 김민중

Why is sun care important all year round?

Sun care is not just for the beach in summer; it is a mandatory step that should be included at the end of your skincare routine every morning. This is because UV rays can penetrate clouds and pass through windows, serving as the primary cause of skin aging and pigmentation.

Basic principles of UV protection

UV protection products are broadly divided into physical and chemical sunscreens. Physical sunscreens form a barrier on the skin's surface to reflect UV rays, while chemical sunscreens absorb UV rays and dissipate them as heat.

Physical sunscreen: Suitable for those with sensitive skin
Chemical sunscreen: Minimal white cast and excellent spreadability

Daily habits to practice

It is important to apply a sufficient amount to exposed areas, including the face, neck, and back of the hands, 20 minutes before going out each morning. In the Korean beauty industry, sunscreen is seen as an extension of basic skincare, with the priority placed on forming a protective layer before applying makeup. Even if you spend most of your time indoors, UV rays can still enter through windows, making consistent daily use essential.

Criteria for choosing sun care by skin type

Selecting a sun care product tailored to your skin type is key to preventing skin troubles and achieving a satisfying feel. The Korean cosmetics market offers a wide range of products with various textures, providing plenty of options.

Differences between oily and dry skin

For oily skin, it is recommended to choose lotion or gel types that are low in oil and provide a fresh finish. On the other hand, for dry skin, using a moisturizing cream type that contains hydrating ingredients is effective in preventing skin tightness.

Oily skin: Oil-free, matte finish, sebum control
Dry skin: Contains hyaluronic acid, creates moisture barrier, creamy texture

Checking ingredients for sensitive skin

Those with sensitive skin should choose products with mild ingredients to minimize irritation. Prioritize products that are free from fragrances or dyes, and consider those with soothing ingredients to help calm heat caused by UV exposure. It is advisable to check the ingredient list on the back of the product to ensure there are no components that may not suit your skin.

Proper application steps and tips for reapplication

To maximize the effects of sun care, it is important not only to apply it once but to use the correct amount in the right order. In Korean beauty routines, sunscreen is used as the final step of skincare to protect the skin.

Thorough application methods

To spread the product evenly over the entire face, using an amount equivalent to the length of two fingers is recommended. Rather than applying a large amount at once, layering thin applications is the secret to preventing pilling and forming a more uniform UV protection barrier.

Recommended amount: Two finger lengths (index and middle)
Application order: After basic skincare, before makeup

How to reapply during outdoor activities

On days with long outdoor activities, you should reapply sunscreen every 2 to 3 hours. If it is difficult to reapply sunscreen over makeup, using a sun cushion or sun stick is recommended. These tools are very popular for portability as they allow for easy UV protection without getting your hands dirty. Choosing a waterproof product that resists sweat and water can help maintain strong protection for longer.

Frequently Asked Questions

Should I apply sun care products every day even when indoors?+

It is recommended to apply sun care products daily even when indoors to protect your skin from UV-A rays that enter through windows. Since UV-A penetrates deep into the skin and is a primary culprit for aging, making it a habit to apply it thoroughly during your morning routine is a great way to maintain skin health.

What is the difference between physical and chemical sunscreens?+

Physical sunscreens work by creating a protective barrier on the skin's surface to reflect UV rays, while chemical sunscreens absorb UV rays and convert them into heat to be released. Physical sunscreens are gentle on sensitive skin, while chemical sunscreens are known for their smooth application and lack of white cast, so you can choose based on your individual skin type.

What is an effective way to reapply sun care over makeup?+

The most effective way to reapply sun care over makeup is to use a sun cushion or sun stick. Applying it with a light tapping motion helps prevent the existing makeup from smudging or pilling, and it is very practical for outdoor activities as you can reapply without getting your hands dirty.
