Ingredients Side-by-side
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Preservative 5 Benefits 4 Concerns
Salicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.
Polysorbate 20 is made by combining ethoxylation of sorbitan, ethylene oxide, and lauric acid. It is a mild cleansing agent, surfactant, and emulsifier.
Camellia Oleifera Leaf is a green tea plant native to China. It is closely related to Camellia sinensis. Both plants have very similar properties.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
Tetrasodium EDTA is the salt formed from neutralizing ethylenediamine tetraacetic acid with sodium hydroxide. It is a chelating agent and used to prevent metal ions from binding to other ingredients. This helps keep the product and ingredients stable.

6 Benefits
Niacinamide has emerged as an all-star ingredient due to its many benefits.
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
Propanediol helps absorb ingredients into your skin, boosting their benefits. It can act as an emollient, making your skin softer. Propanediol can help products last longer by boosting the properties of preservatives within the formulation.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and microbial growth. By itself, it has a scent that is similar to that of a rose.
This is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel.
Hydroxyethylcellulose is used to improve the texture of products. It is created from a chemical reaction involving ethylene oxide and alkali-cellulose. Cellulose is a sugar found in plant cell walls and help give plants structure.
Phospholipids are naturally found in our skin as they are the main component of cell membranes. Phospholipids have humectant, emollient, antioxidant properties.
Squalane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
Not safe for Fungal Acne
Glycine Soja Oil comes from the soybean. Glycine Soja is native to eastern Asia.
Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Sodium Phytate is the synthetic salt form of phytic acid. Phytic acid is an antioxidant and can be found in plant seeds.
Polysorbate 60 is used to help stabilize products. It is a surfactant and emulsifier. These properties help keep ingredients together in a product. Surfactants help reduce surface tension between ingredients with different states, such as liquids and solids. Emulsifiers help prevent oils and waters from separating.
Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.
Leuconostoc/Radish Root Ferment Filtrate is a natural preservative. It comes from fermenting radish roots with a bacteria called leuconostoc. Leuconostoc comes from lactic acid. This bacteria is used to make the traditional Korean side-dish, kimchi. It is also used to make sourdough bread (both incredibly yummy foods).
Sorbitan Isostearate is an emulsifer and cleaning agent. It is created from isostearic acid and sorbitol.
Glycine Soja Sterols is derived from the soybean plant. Sterols are an organic compound and technically an alcohol.
4 Benefits 2 Concerns
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

Hyaluronic acid is naturally found in healthy skin. It is a humectant, meaning it draws moisture to your skin.

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

The first night I used Paula’s choice exfoliant just once, it cleaned up my skin scraping it whole, I was left GLOWING but it felt kind of tight like I had been using corsx salicylic acid for 3 days straight, it takes some getting used to, to the extent that the instructions literally say to start off once a week and slowly build your usage up overtime, it’s really strong but does the job well. I’ve noticed that if I overuse it, I get extremely coarse skin and whiteheads slowly appear in the places I use it most (my nose). This is why I highly advise to purchase the small sample bottle first and to build your way up, at MOST every other day. I’ve used it 3-4 times a week since and on the few days I don’t I use a daily-friendly exfoliant toner pad so my skin barrier isn’t destroyed but bacteria doesn’t also build. It dries up all the forehead gunk, removes residue on the sides of my nose and dried up the pimples I had been trying to rid of for so long, my skin is left gleaming, exfoliated as ever, and I know my skin wouldn’t be as flawless without it. 30ml sample version Lasted 2 months from Dec-Feb used every other day. I now use the 118ml version since Feb and there’s plenty left, will most likely last for about 7 months and 3 weeks in total (based on how long i went through the sample size). As much as I love this I deeply suggest researching and sampling because there are mixed reviews of people claiming that it ruined their skin which doesn’t surprise me -since it is pretty harsh exfoliant and skin is diverse. I tend to be wary of western products but one thing western products do well is harsh exfoliants. If you have a lot of bacterial residue, sebaceous filaments and the feeling of gunk on your face even after your exfoliant, this is a good one to consider. This combined with my Needley daily Toner pad is the only reason why my forehead looks like a glazed doughnut

Viral for a REASON
This product is popular for a reason. Back in the day [showing my age] we used to use Noxzema and Stridex for our acne. But those products were so harsh, burned, and didn't produce any results. This product not only clears pores but is also nourishing [suspect it is the green tea]. After I apply, my skin doesn't feel raw or sensitive. The formulation of this product is FANTASTIC. Truly viral for a reason. It will forever be in my skincare collection.

SUPER GOOD
I had redness on my cheeks and this product got rid of it! It’s super cheap and it’s seems small but it lasted me like 3 months. It’s very lightweight but it has a little bit tacky finish but after you layer it with moisturizer it feels good. Did such a great job. Recommend!

Did not irritate my rather sensitive skin, and I like that it also has hyaluronic acid. However, I hate the bottle, it feels like I bought it at the dollar store.
