All About Sun Care: The Right Way to Protect Your Skin According to K-Beauty Experts

BY 김민중

Why Is Sun Care the Core of Skin Care?

Sun care is the most basic step for maintaining healthy skin and is essential throughout all four seasons. UV rays are the primary culprit behind skin aging and are known as a major cause of dark spots and blemishes. In the K-beauty market, products that go beyond simple UV protection to include skin soothing and hydration benefits are gaining significant attention.

Key Functions of Sunscreen

UVA Protection: Blocks UV rays that penetrate deep into the skin, reducing elasticity and causing wrinkles.
UVB Protection: Blocks UV rays that burn the skin surface and cause redness.
Skincare Ingredients: Many recent products contain soothing ingredients like hyaluronic acid and Centella asiatica extract.

Daily Sun Protection Habits

It is best to apply sunscreen not only before going outside but also indoors to protect against UV rays that enter through windows. Sunscreen should be used as the final step of your basic skincare routine, and the key is to apply a sufficient amount evenly over the entire face. Pay special attention to the neck and behind the ears, as these areas are often overlooked. While it is recommended to reapply every 2 to 3 hours when outdoors, using a cushion or powder with UV protection is an efficient way to top up after makeup. Since product textures vary—including lotions, creams, sticks, and sprays—it is important to choose one that fits your skin type and environment.

How to Choose Sun Care Products by Skin Type

Selecting the right sun care product is essential for preventing skin troubles and improving comfort. Since preferred textures and ingredients vary by skin type—such as oily, dry, or sensitive—you should check these details carefully.

Choosing Textures Based on Skin Type

Oily Skin: Choose oil-free or refreshing gel-type sunscreens to minimize shine.
Dry Skin: Cream-type products rich in moisturizing ingredients help prevent dryness and add a healthy glow.
Sensitive Skin: Products containing physical UV filters (mineral sunscreen) like zinc oxide or titanium dioxide help reduce skin irritation.

Checklist for Product Selection

Checking the SPF and PA ratings on the back of the product is fundamental. SPF measures UVB protection, while PA indicates UVA protection. SPF 30/PA+++ is generally sufficient for daily life, but it is safer to use SPF 50+/PA++++ products for extended outdoor activities. Additionally, if you are concerned about eye stinging, prioritize mineral-based products. Recently, K-beauty brands have introduced many products that improve upon the white cast issues typically associated with mineral sunscreens. As this product comes into direct contact with your skin, make it a habit to check the ingredients and perform a patch test to see if your skin reacts to specific components.

Cleansing Steps for Effective Sun Care

Proper cleansing is the final step of your sun care routine. Sunscreen contains ingredients that adhere to the skin to reflect or absorb UV rays, so standard face washing may not remove all residue. Since leftover product can clog pores and cause breakouts, a proper cleansing routine is vital.

The Importance of Double Cleansing

Step 1: Use a cleansing oil or balm to gently melt away the sunscreen and impurities from your entire face.
Step 2: Use a mild, low-pH cleansing foam to remove remaining residue while protecting the skin barrier to finish your cleanse.

Precautions During Cleansing

When cleansing, it is important to roll gently as if massaging to avoid irritating the skin. If you have used a waterproof sunscreen, extra care is needed. After washing, immediately use a hydrating toner or essence to form a moisture barrier and prevent dryness. Simply removing all sunscreen residue can keep your skin in a much healthier condition. Remember that cleansing is an extension of sun care, and make it a habit to wash your face thoroughly every night for clear, clean skin.

Frequently Asked Questions

Should I apply sun care products every day?+

Yes, it is crucial to use sun care products every day, both indoors and outdoors, for skin health. Because UV rays pass through windows and reach the earth even on cloudy days, you must make it a habit to apply sunscreen as the final step of your morning skincare routine to prevent skin aging and pigmentation.

What is the difference between mineral and chemical sunscreen?+

Mineral and chemical sunscreens are distinguished by how they block UV rays. Mineral sunscreens form a barrier on the skin surface to physically reflect UV rays and are generally less irritating. Chemical sunscreens absorb UV rays and release them as heat, which often provides a smoother application and leaves little to no white cast. Choose the one that best suits your skin type.

How should I wash my face after using sun care products?+

On days when you use sun care products, double cleansing is recommended to remove ingredients trapped in the pores. First, use a cleansing oil or balm to fully dissolve the sunscreen, then gently wash away the residue with a cleansing foam. This double-cleansing method prevents clogged pores and helps maintain clear, trouble-free skin.
