Choosing a Korean Low-pH Cleanser for Dry or Sensitive Skin: How to Read pH Values and Moisturizing Ingredients

bttr Milk to Foam Cleanser 150g 150g is priced at 28,100 KRW on the official site, and as of the 2026-09-14 check it had accumulated 692 reviews with an average rating of 4.6. When dry or sensitive skin is choosing a low-pH cleanser, what matters isn't a single pH number but the types of moisturizing ingredients in the full ingredient list and how mild the surfactants are. This cleanser publicly lists 44 ingredients in total, including 3 types of hyaluronic acid and 6 types of ceramide, with surfactants centered on amino acid based sodium cocoyl alaninate and glucoside based coco glucoside and lauryl glucoside. None of the 44 listed ingredients are sulfate based surfactants such as SLS or SLES.
A low-pH cleanser is only the first step. For dry skin, it's not advisable to layer a low-pH cleanser together with AHAs or retinol type active skincare in the same routine. Keeping cleansing and active skincare steps separate helps prevent flaking and tightness from getting worse.
bttr Milk to Foam Cleanser 150g 150g
By the standard of checking moisturizing ingredients and surfactant types, the official site positions this cleanser as a low-pH foaming cleanser, listing a 336 formula made up of 3 types of hyaluronic acid and 6 types of ceramide. It's marketed as a single product that can remove both sunscreen and light makeup without needing a separate cleansing oil step.
In terms of surfactant composition, the amino acid based sodium cocoyl alaninate ranks second in the full ingredient list, paired with nonionic glucoside based surfactants such as coco glucoside and lauryl glucoside, as well as the amphoteric surfactant disodium cocoyl glutamate. Among the 44 total ingredients, no sulfate based cleansing agents such as SLS or SLES appear. Beyond the 3 types of hyaluronic acid (sodium hyaluronate, hydrolyzed hyaluronic acid, and sodium acetylated hyaluronate) and 6 types of ceramide (NP, AP, AS, NG, NS, EOP), the moisturizing ingredients also include cholesterol and stearic acid.
For dry and sensitive skin types prone to tightness and redness after cleansing, a formula built mainly on amino acid and glucoside based surfactants, with no sulfate based cleansing agents in the full ingredient list, directly addresses the need for a wash that doesn't leave skin feeling tight.

ROUND LAB 1025 Dokdo Cleanser
The official product page lists this cleansing gel's pH as between 5.0 and 6.0, with ingredients including Dokdo deep sea water, triple hyaluronic acid, panthenol, allantoin, and ceramide NP.
The official page only gives a 5.0 to 6.0 range, without specifying a single precise value, and it does not list the full set of surfactants.
COSRX Low pH Good Morning Gel Cleanser
The official pH is listed as 5.31±1.00, with the formula built around a combination of betaine salicylate (BHA) and tea tree oil.
The official site positions this cleansing gel as a daily cleanser for oil water balance and tackling dull, congested pores, aimed at oily and combination skin. The BHA in the formula is an exfoliating acid, so this isn't a formula primarily designed around moisturizing ingredients.
beplain Mung Bean pH-Balanced Cleansing Foam
The official pH is listed at 5.5, with ingredients including about 33% mung bean extract and mung bean seed powder, along with glycerin, ceramide NP, centella asiatica, and turmeric extract.
The official ingredient description specifically notes that mung bean powder provides a physical pore cleansing effect, meaning this foam contains fine particles. It's a cleanser with a noticeable scrub-like texture, unlike the other pure gel or pure foam formats in this article.

The official product page describes the pH as "low-pH, close to 6," with ingredients including 8 types of low molecular hyaluronic acid, along with panthenol and allantoin.
