Recognize yourself?

Are these problems familiar to you?

Most cleansers cause more problems than they solve. If at least one point below applies to you, keep reading.

  • Skin feels "tight" after washing – A sensation as if a film has been stretched over your face. Basic moisturizers fail to cope with this tight dryness.
  • Oily sheen just an hour later – You've washed your face, and just 60 minutes later, it's shiny again. Aggressive foaming cleansers destroy the protective barrier, sending sebaceous glands into stress mode.
  • Constant breakouts and inflammation – One pimple goes away, the next one appears. An incorrect cleansing pH disrupts the skin's microbiome, triggering acne time and time again.
  • Clogged pores and dull complexion – Blackheads on the nose and chin that just won't disappear. Skin looks tired, dull, and textured—even after resting.

Solution

Why is it all about pH?

Human skin is naturally mildly acidic—its ideal pH ranges between 4.5 and 6.0. This is its protective barrier, the "acid mantle," which locks in moisture and fends off bacteria.

Simply put: most regular cleansing gels and foams have a pH of 7–9. After contact with such products, the skin "panics," loses its protection, and switches to emergency mode—producing more sebum, becoming irritated and vulnerable to inflammation.

COSRX Low pH Good Morning Gel Cleanser operates at pH 5.0–6.0—the ideal range for your skin. It cleanses without destroying the protective barrier. No stress. No consequences.

  • ✓ Cleanses away impurities and excess sebum 
  • ✓ Preserves the skin's protective acid mantle 
  • ✓ Reduces oil production in the long term 
  • ✓ Prepares the skin for better absorption of serums and moisturizers

Ingredients

Key components that work

No complicated chemical abbreviations—just what these components actually do for your skin.

BHA Acids (Betaine Salicylate)

Beta-hydroxy acids are oil-soluble acids that penetrate deep into the pores to dissolve accumulated impurities from within. The result: pores look smaller, skin texture becomes smoother, and blackheads gradually diminish. Unlike physical scrubs—no irritation or micro-damage.

Tea Tree Oil

A natural antiseptic with powerful anti-inflammatory action. Tea tree oil targets inflamed elements precisely: it soothes redness and suppresses the growth of acne-causing bacteria. At the same time, it doesn't overdry the skin like most drugstore acne treatments do.

Application

How to use for best results

Proper cleansing technique is 50% of the result. Follow these steps to make the gel work at its full potential.

  • Wet your face with lukewarm water - Not hot! Hot water dilates pores and worsens dehydration. Lukewarm water is optimal for gentle cleansing.
  • Apply a small amount of gel - A pea-sized amount is enough. Lather it in your palms into a light foam before applying it to your face.
  • Gently massage for 30–60 seconds - In circular motions, without pressure. Pay close attention to the T-zone (forehead, nose, chin), where more sebum accumulates.
  • Rinse thoroughly with cool water - Cool water tones the skin and helps "close" the pores after cleansing.

FAQ

Is the gel suitable for removing makeup?

No, the gel is designed for washing the face, not for removing makeup. For a complete cleanse, we recommend the Double Cleansing method: first, a cleansing oil or micellar water to dissolve makeup and SPF, followed by COSRX Low pH Cleanser as the second step. This is how most K-beauty fans use it.

Can I use the gel in the evening, not just in the morning?

Yes, despite the name "Good Morning", the gel is excellent for evening cleansing as the second step of Double Cleansing after an oil or micellar water. Many people use it twice a day—both morning and night.

Is it suitable for dry skin?

The gel is primarily designed for oily, combination, and problem-prone skin thanks to BHA acids and tea tree oil. It can work for those with dry skin if used without lathering (with a minimal amount of gel), however, COSRX offers alternative options better optimized for dry skin types.

How soon can I expect the first results?

Most people notice the first result—the absence of tightness after washing—immediately. Improvement in the condition of pores, reduced oily sheen, and fewer breakouts usually become noticeable within 2–4 weeks of regular use. The full effect comes after 4–8 weeks of systematic care.
