Sensitive Skin from Masks and Pollen: How to Choose a Korean Cleanser

For skin that's grown sensitive from mask friction and pollen exposure, a foam cleanser with a fragrance free, mildly acidic formula and amino acid based surfactants such as sodium cocoyl isethionate helps reduce irritation. Four products sold in Korea fit this profile: Dr.G Red Blemish Clear Soothing Foam, Purito From Green Deep Foaming Cleanser, ROUND LAB 1025 Dokdo Cleanser, and bttr Hydra Barrier Cleansing 336 Milk to Foam. Below is a rundown of each product's size, price, key ingredients, and where to buy it.

Dr.G Red Blemish Clear Soothing Foam

Dr.G Red Blemish Clear Soothing Foam comes in 150ml and 200ml sizes. As of September 9, 2026, the 150ml size was priced between 13,500 and 15,900 won at Olive Young, depending on ongoing promotions. The brand describes it as a "mildly acidic multi probio derma formula" containing Centella asiatica, madecassoside, and Centella asiatica derived ingredients along with hyaluronic acid. According to the listed full ingredients, the surfactants are sodium cocoyl isethionate, cocamidopropyl betaine, sodium methyl cocoyl taurate, potassium cocoyl glycinate, and coco glucoside, with no SLS or SLES type sulfates. In Korea it's sold at Olive Young stores and online; in Japan it has a product page on @cosme and is also distributed through Qoo10 Japan, so travelers can buy it in Korea and repurchase the same product after returning home.

Purito From Green Deep Foaming Cleanser

Purito From Green Deep Foaming Cleanser is available in a single 150ml size. As of September 9, 2026, it was priced at roughly 14,098 won on iHerb Korea. It can be purchased in Korea through Purito's own online store and the official Purito Seoul store on Coupang; since its availability at Olive Young or Lalavla hasn't been confirmed, it's more reliable to buy it through the brand's own site or other online channels rather than looking for it in physical stores. The brand states the formula has a pH of 5.5 and is fragrance free, with no essential oils or added scent. Its surfactants, sodium cocoyl isethionate, sodium methyl cocoyl taurate, cocamidopropyl betaine, and potassium cocoyl glycinate, are amino acid and coconut derived with no sulfates. In Japan, genuine products are distributed through Purito's official Japanese online store and Qoo10 Japan, so if you don't finish the bottle in Korea you can keep buying it online after you get home.

ROUND LAB 1025 Dokdo Cleanser

ROUND LAB 1025 Dokdo Cleanser comes in three sizes: 150ml, 200ml, and 250ml. As of September 9, 2026, the list price on the brand's own store was 13,000 won for the 150ml size and 17,000 won for the 200ml size, while the 250ml size was priced at about 15,110 won at Olive Young. The brand states the formula has a pH of 5.0 to 6.0 and contains deep sea water from Ulleungdo along with triple hyaluronic acid, panthenol, allantoin, ceramide NP, and beta glucan. The surfactants, sodium cocoyl isethionate, sodium methyl cocoyl taurate, cocamidopropyl betaine, potassium cocoyl glycinate, and potassium cocoate, are likewise sulfate free, and the full ingredient list contains no fragrance. The claim of "99% removal of ultrafine dust simulant" is based on the brand's own testing, and since the testing institution and conditions haven't been disclosed, it's worth reading with that caveat in mind. In Japan, it's distributed through Rakuten and Qoo10 Japan, and it also has a review page on the Japanese version of Hwahae, making it easy to check local reviews.

bttr Hydra Barrier Cleansing 336 Milk to Foam

The [Moisture Lock] Hydra Barrier Cleansing 336 Milk to Foam, 150g, from bttr is listed at 28,100 won on the brand's own store. The brand describes it as a mildly acidic, low irritation foam cleanser built around a "336" blend of three hyaluronic acids (sodium hyaluronate, hydrolyzed hyaluronic acid, and sodium acetylated hyaluronate) and six ceramides (NP, AP, AS, NG, NS, and EOP). Unlike the other three products, it's a one step formula that removes sunscreen and makeup without double cleansing: you first emulsify it as a milk in your hands, then add water to finish it off as a foam. It's worth considering on days when you've layered sunscreen under a mask and want to cut down on cleansing steps.

All four products use mildly acidic formulas with amino acid based surfactants. If mask friction has already left areas of your face red or flaky, avoid squeezing the foam cleanser directly onto your skin and rubbing it in. Instead, work up a full lather in your palms first and pat it onto your face to reduce friction related irritation.
