(Bottle says, “Formulated with botanical skin-purifying ingredients, mildly acidic cleanser works softly to make skin supple and clear. ‘For sensitive skin, Morning time cleanser'”)

I am always on a continuous search for the perfect facial cleanser. I have yet to find one that I would go back to again and again. And as time goes on, my checklist of qualities for the perfect facial cleanser gets even longer. Now I expect a facial cleanser to;

1) Leaves my face feeling clean without over stripping

2) Helps to unclog my pores

3) Doesn’t leave any residue on my skin

4) Lathers well

5) Low pH.

One of facial cleansers I have tried along the way, that I thought might fill these requirements, is the Cosrx Low pH Good Morning Gel Cleanser. This cleanser is made to be used specifically as an AM face wash and it is suitable for all skin types, including sensitive. It is also supposed to have a mildly acidic pH of 5.0-6.0. Cosrx says that you can use it as nighttime cleanser as well, but after your normal cleanser. I have tried this cleanser in my AM and PM routines, and have had a rather positive experience with it. I wouldn’t say that its a holy grail product, but it does the job as a nice, gentle facial cleanser.

Cryptomeria Japonica Leaf Extract- this is a humectant; it’s used to reduce the loss of moisture.

Nelumbo Nucifera Leaf Extract- this is a skin conditioner.

Ulmus Davidiana Root Extrac- this is a skin conditioner.

Pueraria Lobata Root Extract-this is a humectant; it’s used to reduce the loss of moisture.

Melaleuca alternifolia Leaf Oil- this is better known as tea tree oil, and it is an antioxidant that is great for treating acne.

Here are the cursed ingredients:

Butylene Glycol- is an acne irritant of 1.

What Cosrx says to do:

**Taken directly from bottle

  • In the morning time: Gentle massage on wet skin with Good Morning Midly Acidic Cleanser. Rinse thoroughly with tepid water. Start your morning fresh everyday!
  • For day and night time: After you first wash with your normal cleanser, work Good Morning Mildly Acidic Cleanser into a lather. Gently massage on wet skin and rinse thoroughly with tepid water.

What I do:

  • I use this mainly as a morning cleanser, so I first wet my face and then dispense a small amount into my hand (I don’t normally double cleanse in the morning).
  • I massage it between my palms to get it to foam up, and then massage it onto my face.
  • Lastly, I rinse thoroughly.

How it worked for me:

I think that the Cosrx Low pH Good Morning Gel Cleanser is definitely one of the better cleansers I have tried and feel it does deserve some recognition for its gentle, yet effective formula. That being said, I think it is only useful for certain purposes. I prefer to use this cleanser in my AM routine only, even though Cosrx says you can use it in your PM routine as well. I just don’t find that it cleanses my pores well enough to use as a nighttime cleanser, especially after a days worth of sebum and makeup clogging them. I need a deeper facial cleanser for nighttime because of my oily skin, and this just doesn’t cut it. However, it’s perfect for the morning time when it’s especially important not to strip your skin of all its essential oils. My recommendation is that the Cosrx Low pH Good Morning Gel Cleanser works well with all skin types, but for those with oilier skin types, you might want to consider purchasing a different cleanser for at night or using it after another cleanser like Cosrx suggests.


  • Great for cleansing in the morning
  • Doesn’t leave skin feeling tight or stripped
  • But still leaves skin feeling clean
  • Didn’t break me out
  • Works well for all skin types
  • Low pH
  • Travel-friendly
  • Affordable


  • Doesn’t provide a deep enough clean at night for my oily skin
  • Doesn’t do much to treat blemishes (but doesn’t irritate them either)

Final Rating:

5-Holy Grail, it’s the cat’s meow!

Noona 4
This is a wonderful, refreshing morning cleanser, but doesn’t deep clean well enough to be the second step in my nightly double cleanse.

  1. I recently bought this cleanser as well, and I really agree with your review. I find with a foaming net I get a big lather, which helps, but I’m not sure how well it’s doing at night cleansing.
    Do you have an idea what 2nd cleanser you will try next?


    1. I’m glad to hear it works well for you as a morning cleanser too! I don’t use a foaming net, but I’ve heard good things.

      As for my second cleanser, I still have yet to find one that I really like. This is a constant struggle for me. At this moment I am trying to finish up what I have so that I can try a new one. I am currently using the Innisfree Jeju Volcanic Pore Cleansing Foam and Cosrx Salicylic Acid Exfoliating Cleanser, but find them to be a little too stripping for my liking. The other cleanser I am using is the B & C Cleansing Research Make Up Cleansing Wash with AHA and I actually really like this one, but it’s hard to find. I wish I could be of more help!
