COSRX Low pH Good Morning Gel Cleanser at a glance

Why pH matters in a cleanser

Healthy skin sits at a slightly acidic pH of around 5.5. Many cleansers are alkaline, which strips the barrier and leaves skin tight and reactive. This one is formulated at a low pH that matches the skin's own, so it cleans effectively without disrupting the acid mantle. That is not marketing — it is basic chemistry, and it is why this cleanser has stayed popular for years while trends come and go.

The tea tree oil adds a mild antiseptic, refreshing quality, and a small amount of BHA (betaine salicylate) gives light pore-clearing action. Being honest: in a rinse-off cleanser both ingredients have brief contact, so think of them as supporting freshness rather than treating acne. The real value is in the pH and the gentle formula — a cleanser that does not damage your barrier makes everything else in your routine work better. It is the least glamorous step that makes the biggest difference.

How to use it

1. Wet your face, squeeze a small amount into your palms and work into a light lather.
2. Massage over the face for 20 to 30 seconds, avoiding the eyes.
3. Rinse with lukewarm water and pat dry.
4. Follow with toner, essence and moisturiser, and sunscreen every morning.

Frequently asked questions

Why does pH matter in a cleanser?

Skin is naturally slightly acidic (around pH 5.5). Alkaline cleansers strip the barrier, causing tightness and reactivity. A low-pH cleanser cleans without disrupting that balance.

Is it good for acne-prone skin?

Yes. The low pH protects the barrier, and the tea tree and BHA support a cleaner, fresher complexion. It is not a treatment, but it is a smart foundation for an acne-focused routine.

Will it dry out my skin?

It is gentler than most gel cleansers, but if your skin is very dry, you may prefer a cream or milk cleanser. Most skin types find it comfortable for daily use.

Can I use it morning and night?

Yes. It is mild enough for twice-daily use. In the evening, if you wear heavy makeup or sunscreen, use a cleansing oil first, then this as a second cleanse.

How is it different from the Salicylic Acid Cleanser?

This one is lighter and more barrier-friendly for everyday use. The Salicylic Acid cleanser foams more and has stronger pore-clearing action, making it better for oilier, more congested skin.

Does the tea tree smell strong?

It has a mild, fresh scent that rinses away. Most people find it pleasant and unobtrusive.

How long does a tube last?

At a pea-sized amount twice daily, 150ml typically lasts two to three months.
