Product details

COSRX Low pH Good Morning Gel Cleanser 150ml is a mildly acidic Korean face wash for daily buildup, excess oil and rough-feeling texture. Betaine salicylate, a BHA ingredient, helps lift dead skin cells as the cleanser washes away impurities.

The clear gel works into a light foam and rinses away for a fresh, soft feel. Its low-pH formula is designed to cleanse without a stripped feeling, while allantoin supports skin comfort. It contains tea tree leaf oil, so skin sensitive to essential oils may prefer a different cleanser.

Lather a small amount on wet hands, gently massage over damp skin and rinse thoroughly. Use morning and/or night as comfortable, after an oil or balm cleanser in the evening when needed. Follow with moisturizer and finish your morning routine with SPF 30 or higher.

Formula, ingredients & use

Why you’ll love it

  • The mildly acidic formula is designed to cleanse while helping maintain skin’s moisture balance.
  • A light foaming lather washes away excess oil, impurities and daily buildup.
  • Betaine salicylate, a BHA ingredient, helps lift dead skin cells for smoother-feeling texture.
  • Allantoin supports skin comfort during a rinse-off cleanse.
  • The lightweight gel fits a morning wash or the second step of an evening double cleanse.

Best for

Best for: Daily buildup, excess oil, rough-feeling texture and dull-looking skin.

Skin type fit: A daily option for normal, combination and oily skin, and dry skin that tolerates foaming cleansers. Sensitive or very dry skin should patch test and adjust frequency. The formula contains tea tree essential oil and betaine salicylate, so it may not suit skin that reacts to essential oils or salicylates.

What to expect

Format: One 150ml / 5.07 fl oz squeeze tube with a flip-top cap.
Texture: A clear gel that forms a light foam when mixed with water.
Finish: Fresh, soft and clean-feeling skin. Reduce frequency if skin feels tight or dry.
Scent: Contains tea tree leaf oil, which can give a herbal scent. No fragrance/parfum is listed in the current formula; it is not essential-oil-free.
Routine step: A water-based facial cleanser before toner, essence and moisturizer. Use after makeup remover, cleansing oil or balm at night when needed.

How to use

  1. Wet your hands and face with lukewarm water. Work a small amount of cleanser into a lather between your palms.
  2. Gently massage the foam over damp skin, avoiding the eye area and lips. Do not scrub or leave it on as a mask.
  3. Rinse thoroughly and pat dry. Follow with a hydrating toner or essence if desired, then moisturizer.
  4. Start once daily and use morning and/or night as your skin tolerates. At night, remove makeup or water-resistant sunscreen first when needed. Finish your morning routine with broad-spectrum SPF 30 or higher.

Important safety notes

  • Patch test before first use and introduce one new exfoliating product at a time.
  • Contains betaine salicylate. Do not use if you are allergic to aspirin or salicylates.
  • For external use only. Avoid contact with eyes; rinse thoroughly with water if contact occurs.
  • Do not use on wounded or irritated skin. Reduce frequency if skin feels dry or tight, and stop use if irritation occurs. Seek professional advice if symptoms persist.
  • Not for children under 3 years of age. Keep out of reach of children.

Key ingredients

  • Betaine Salicylate: A BHA ingredient that helps lift dead skin cells and smooth the feel of uneven texture during cleansing.
  • Allantoin: Helps support skin comfort as part of the rinse-off formula.
  • Cocamidopropyl Betaine and Sodium Lauroyl Methyl Isethionate: Cleansing ingredients that create the lather and help wash away oil and impurities.
  • Tea Tree Leaf Oil: A featured botanical ingredient with an aromatic scent. Patch test if your skin is sensitive to essential oils.
