All About Sun Care: An Expert Guide from Korean Beauty Professionals

BY 김민중

Why is daily sun care essential?

The most basic yet crucial step to maintaining healthy skin is consistent sun care. Since UV rays do more than just tan your skin—they are the primary culprits behind skin aging and pigmentation—it is necessary to make applying sunscreen a daily habit, regardless of the season or weather.

The role of sunscreen ingredients

UVA protection: Blocks UV rays that penetrate deep into the skin, causing aging and wrinkles.
UVB protection: Blocks UV rays that burn the skin and cause redness.
PA rating: Indicates the level of UVA protection; more '+' signs mean higher protection.
SPF rating: Indicates the level of UVB protection; SPF 30 or higher is recommended for daily use.

Daily sun care habits

In Korean beauty routines, sunscreen is considered the final step of basic skincare. It is most effective when applied 20 minutes before going out, and it is important to use a sufficient amount to ensure an even layer over the entire face. Don't forget to pay attention to easily missed areas like behind the ears, the neck, and the back of the hands to maintain an even skin tone. Since sunscreen can be removed by sweat or sebum over time, we recommend reapplying every 3 hours on days with significant outdoor activity.

How to choose sunscreen by skin type

Choosing a sunscreen product suited to your skin type is the key to reducing irritation and improving makeup adherence. Understanding the characteristics of your skin—whether dry, oily, or sensitive—makes it much easier to choose the right product.

Tips for choosing formulas by skin type

Dry skin: Choose a moisturizing, hydrating cream-type sunscreen.
Oily skin: We recommend lotion or gel types that have sebum-control functions or a fresh, matte finish.
Sensitive skin: Products containing physical (mineral) blockers are less irritating than chemical sunscreens.
Combination skin: Lightweight formulas that keep the T-zone matte and the U-zone hydrated are ideal.

Things to check in the ingredient list

It is a good idea to check the ingredient label on the back of the product to see if there are any components that don't suit your skin. Recently, products containing soothing ingredients like Centella Asiatica extract or panthenol have become very popular in the Korean beauty market. These ingredients help soothe skin sensitized by UV rays. Also, using a product that doubles as a makeup base can save you time.

The importance of proper sun care cleansing

Just as important as effective sun protection is the cleansing step to remove it after you return home. Because sunscreen is designed to adhere to the skin, it is likely to leave residue behind with simple face washing, so double cleansing is highly recommended.

Cleansing steps to remove sunscreen

Step 1: Use an oil-based cleanser to gently dissolve the sunscreen residue on your skin.
Step 2: Use a foam cleanser to thoroughly wash away remaining impurities and excess oil.
Caution: Do not scrub too hard; lather the cleanser well to minimize skin friction.

Skincare after cleansing

Skin can easily become dry immediately after cleansing. Therefore, it is recommended to use a hydrating toner or soothing ampoule right away to lower the skin's temperature and provide moisture. Skin exposed to UV rays requires immediate cooling and hydration, so we recommend a routine that includes applying a generous amount of aloe gel or a moisturizing cream. Remember that true sun care is only complete when proper cleansing and follow-up care are performed together.

Frequently Asked Questions

Is sun care necessary even on cloudy days?+

Sun care must be practiced as long as UV rays exist, regardless of the weather. Even on cloudy or rainy days, UV rays pass through clouds and reach your skin. Therefore, it is recommended to apply sunscreen daily to block UV rays that enter through windows, even when you are indoors.

What is the difference between physical and chemical sunscreens?+

Sun care products are largely divided into physical (mineral) and chemical sunscreens. Physical sunscreens form a barrier on the skin surface to reflect UV rays and are suitable for sensitive skin. Chemical sunscreens work by absorbing UV rays and breaking them down into heat, often featuring a smoother application and less white cast. Choose according to your skin's sensitivity.

When and how should I reapply sunscreen?+

To maintain the effectiveness of your sun care, it is best to reapply every 2–3 hours during outdoor activities. If you are wearing makeup, using a sun spray or sun cushion to lightly pat the product onto your skin will allow you to reinforce your UV protection barrier without ruining your makeup.
