Where to buy Pyunkang Yul Low PH Pore Deep Cleansing Foam?

This cleanser was not gifted; I bought it with my own money. You can purchase the full size from StyleKorean*, Amazon*, YesStyle*, and Pyunkang Yul US.
Pyunkang Yul Brand
Launched in March 2016 by the renowned Pyunkang Korean Medicine Hospital, a hospital known for treating atopic skin disorders, Pyunkang Yul believes healthy skin is attained by maintaining its oil and moisture balance. The brand also avoids unnecessary chemical substances in its products. Pyunkang Yul is a clean brand that only uses natural, gentle ingredients on the skin.
I have heard a lot of nice things about Pyunkang Yul, and as a matter of fact, I have already enjoyed their shampoo.
This cleansing foam removes dirt, oil, and makeup from the skin. Its low pH (around 5) leaves the skin balanced and hydrated after every wash. It claims to exfoliate the skin for a smooth and soft touch while protecting irritated, sensitive skin with a blend of soothing extracts from Centella Asiatica and Tea Tree.

Key Ingredients
Glycerin
Glycerin is a very effective humectant, used in many moisturizers to increase skin hydration. It occurs naturally in your skin as part of its home-grown moisturizing system, the natural moisturizing factor (NMF).
Like other humectants, it works by sitting in the top layers of your skin and attracting water from the air and the deeper layers, leaving your skin surface plump and hydrated, even when the weather is arid. This ingredient softens the skin so other hydrating ingredients can more easily penetrate the skin.
Glycerin also keeps the skin’s lipids flexible, strengthening your skin barrier.
Sulfates & Surfactants
Sodium Cocoyl Isethionate
Sodium Cocoyl Isethionate, the first surfactant in this product, is less irritating since it is derived from coconut and is rich in fatty acids. However, you may want to know if you have any coconut oil sensitivities.
Sodium Methyl Cocoyl Taurate
Sodium Methyl Cocoyl Taurate is a mild surfactant derived from coconut. It contains fatty acids and is also known as a foaming agent.
Potassium Cocoyl Glycinate
Potassium Cocoyl Glycinate is a coconut-based surfactant considered a very gentle cleanser.
Centella Asiatica Extract
Centella Asiatica Extract provides skin-soothing benefits and accelerates skin cell regeneration;

Witch Hazel Extract
Witch hazel is an astringent rich in antioxidants that reduce inflammation and decreases oil in the skin, which is great for acne-prone skin. Witch Hazel helps minimize the appearance of pores.
Tea Tree Leaf Extract (10,000ppm)
Aside from calming skin inflammations, Tea Tree also balances the oil-moisture level of the skin;
Citric Acid
Citric Acid exfoliates and softens skin texture.

Packaging
The Pyunkang Yul Low PH Pore Deep Cleansing Foam comes in a white and blue plastic squeeze tube. The product comes in a 3.3 fl. oz. / 100 ml tube or a 1.3 fl. oz. / 40 ml tube; I got the large one.
Scent
I have a high tolerance for fragrance, but this one puts me off. However, I learned to ignore its powerful tea tree scent as I use it every day.

Texture
The Pyunkang Yul Low PH Pore Deep Cleansing Foam comes out as a cream but foams up right away when lathered.

My experience
Let me share my experience with the Pyunkang Yul Low pH Pore Deep Cleansing Foam.
I don’t find it to be extremely gentle on my skin. It is a bit drying, but that doesn’t bother me since I moisturize well after.
I also like the ingredients that aren’t harsh on my sensitive skin and that it doesn’t burn my eyes.
It foams pretty nicely, and it does its job cleansing well and removing makeup like my nonwaterproof mascara.
You only need a small amount for your face, so the 3.3 fl. oz. / 100ml package will last you a few months, which is always good.
Low-pH cleansers are not just for removing dirt and sebum, but they also protect the skin’s acid mantle. According to studies, the ideal pH in facial cleansers should be around 5.5 to 6. Personally, anything seven and higher is a no-go for me.

How do you use the Pyunkang Yul Low PH Pore Deep Cleansing Foam?
- Wet the face;
- Squeeze a small amount of cleansing foam on the palm;
- Lather and gently massage the skin;
- Rinse thoroughly after;
- Follow with your favorite toner and the rest of your skincare routine.
I use this as my morning cleanser. It is appropriate as a second cleanser after a cleansing oil for those who double cleanse.

Pros
- It dried out the pimples – my skin’s reaction to the previous cleanser I’d used. Thank you so much!
- It cleanses my skin thoroughly;
- It does not sting my eyes;
- It does not trigger eczema and even calms skin irritation;
- My skin looks fresh and bright!
Cons
- The smell is too strong;
- Mildly drying
Final thoughts
As for my verdict: there may be an unpleasant scent, but the pros outweigh the negatives. I am in awe of the results, and this cleanser will be back on my shelf!

As always, you do you, be kind to your skin and yourself!
Remember that every person’s skin and skin type is different, so what might work for me might not work for you, and vice versa.
So before trying a new product, it pays to do a little research first. Pay special attention to ingredients that you might react to.
Doing a patch test is always a good idea. Unsure? Best to consult your dermatologist.
Happy skin experimenting!
