COSRX Low pH Refreshing Morning Cleanser 150ml
COSRX Low pH Refreshing Morning Cleanser 150ml is a pH 5.5 balanced AM face wash formulated to cleanse gently without disrupting the skin's natural acid mantle or microbiome. Most conventional cleansers have a high alkaline pH (8–10) that strips the skin's protective acid barrier — leaving skin vulnerable to bacteria, dehydration, and breakouts for hours after washing. This COSRX formula maintains the skin's ideal slightly acidic pH, ensuring that the barrier is intact and the microbiome is undisturbed from the very first step of the morning routine. The gel-to-foam texture effectively removes overnight sebum, sweat, and product residue without stripping. Hyaluronic Acid and botanical extracts maintain hydration through the cleanse. The 150ml size provides generous value for daily AM use. Vegan and suitable for all skin types including sensitive.

Description
COSRX Low pH Refreshing Morning Cleanser 150ml — pH 5.5 Balanced AM Face Wash
COSRX Low pH Refreshing Morning Cleanser 150ml is a Korean skincare staple engineered around one scientifically critical principle: cleansing should not disrupt the skin's acid mantle. At pH 5.5 — matching the skin's natural surface pH — this morning cleanser removes overnight sebum, sweat, and residue without triggering the alkaline disruption that conventional face washes cause. The result: a skin barrier that remains intact and a microbiome that remains undisturbed from the very first step of the day, giving all subsequent actives (serums, SPF) an optimally primed surface to work on.
Why pH Matters in a Morning Cleanser
- Acid mantle preservation: pH 5.5 keeps the skin's protective acidic surface layer functional — conventional high-pH cleansers (pH 8–10) strip it with every wash
- Microbiome protection: A matched pH sustains the beneficial bacterial flora on the skin that guard against infection, sensitivity, and inflammation
- Active ingredient optimisation: Vitamin C and BHA serums applied immediately after work at peak efficacy on pH-balanced skin
- Hyaluronic Acid: Prevents post-cleanse dehydration — skin feels refreshed and balanced, not tight or stripped
- Botanical extract soothing: Calming plant extracts reduce morning skin sensitivity before layering serums and SPF
- Gel-to-foam texture: Rinses cleanly without residue — ideal lightweight weight for the first step of an AM routine
- 150ml economy size: Generous volume for daily AM use — excellent value for a premium formulation cleanser
How to Use
- Wet face with lukewarm water — use every morning as the first step
- Lather a small amount between palms, massage gently onto face for 30–60 seconds, rinse thoroughly
- Follow immediately with toner, serum, moisturiser, and SPF sunscreen

Usage & Benefits
- pH 5.5 balanced formula: Matches the skin's natural acid mantle pH — prevents the post-cleanse alkaline disruption that weakens the barrier and invites bacteria and sensitivity

- Hyaluronic Acid: Supports skin hydration through the cleansing step — skin feels refreshed and balanced, not tight or dry, after rinsing
- Botanical extract soothing: Calming plant extracts reduce any potential morning skin sensitivity or redness before the rest of the routine is applied
- Gel-to-foam texture: Light lather that rinses cleanly without residue — ideal lightweight texture for morning use before layering serums and SPF

- 150ml economy size: Generous volume for daily AM use — excellent value for a high-formulation-quality Korean skincare cleanser
How To Use
FAQs
Why does pH matter in a face wash?
The skin's surface has a naturally slightly acidic pH (around 4.5–5.5) that maintains the protective acid mantle and supports beneficial skin microbiome bacteria. Most conventional cleansers have a pH of 8–10 — far too alkaline — which disrupts this balance after every wash, leaving skin prone to dryness, sensitivity, and bacterial overgrowth for hours. A pH 5.5 cleanser like this one preserves the acid mantle so the skin's protective systems remain functional after cleansing.
How is this different from the COSRX pH Balanced Morning Gel Cleanser (50ml)?
Both products share the same core pH-balancing philosophy. The key differences are: this 150ml version comes as a liquid/foaming cleanser in a larger economy size for value-focused daily users. The 50ml Gel Cleanser is a gel-specific texture in a smaller, more portable format. The formulations have distinct ingredients and textures suited to different user preferences.
Is this suitable to use before applying active serums like vitamin C or BHA?
Yes, and this is one of its key advantages. Because it leaves skin at the correct pH, active ingredients like Vitamin C and BHA applied immediately after will work at their optimal effectiveness — unlike after a high-pH cleanser that requires the skin pH to self-correct over time.
Can I use this at night as well as in the morning?
Yes. While positioned as a morning cleanser, the formula is gentle enough for PM use too. However, for evening cleansing with heavier makeup or sunscreen, a dedicated makeup-removing cleanser or oil cleanser may be more effective as a first step.
