Salix Alba Bark Water

What it does: Astringent, Skin Conditioning, Soothing, Tonic

Community Rating: Liked

Salix Alba Bark Water is created by distilling parts from the white willow tree. The white willow tree is native to Europe and Central Asia.

Salix Alba Bark has often been described as salicylic acid's cousin. This is due to the salicin it contains. However, studies are limited showing salix alba bark to be an effective salicylic acid alternative.

Salicin does have anti-inflammatory and antioxidant properties. It has shown to decrease the formation of inflammatory mediators, such as tumor necrosis factor-α and nuclear factor-kappa B. Salicin also has a mildly exfoliating effect on the skin.

As an astringent, salix alba bark water helps tighten the skin by drawing water out. This helps reduce the appearance of large pores.

Butylene Glycol

What it does: Humectant, Masking, Skin Conditioning, Solvent

Community Rating: Mixed

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
It is a humectant, which means that it helps attract moisture into the skin.
It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Betaine Salicylate

What it does: Antimicrobial

Community Rating: Liked

Betaine Salicylate is considered a salicylic acid alternative.

Limited studies exist proving this ingredient to be a complete alternative to salicylic acid. Based on existing research, this ingredient does not penetrate as deeply and is not shown to be as effective.

However, this makes it a great choice for those with sensitive skin or need gentle BHA action.

This ingredient is created using betaine and salicylic acid.

This ingredient is oil-soluble and is most effective at a pH range of 3.8-4.2.

Niacinamide

What it does: Smoothing

Community Rating: Loved

Niacinamide has emerged as an all-star ingredient due to its many benefits.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

1,2-Hexanediol

Community Rating: Mixed

Arginine

What it does: Masking, Skin Conditioning

Community Rating: Mixed

Xanthan Gum

What it does: Emulsifying, Emulsion Stabilising, Gel Forming, Skin Conditioning

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.

Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

Gently Exfoliates
I decided to try a leave-on exfoliator rather than an exfoliating cleanser because I noticed I kept getting irritation from exfoliating cleansers. This Cosrx one is really gentle and pleasant. It takes a few minutes for it to absorb into my skin, but afterwards I get very little irritation and my skin texture and pore appearance have definitely improved.

This was only the second BHA product that I ever tried and got this because I just don't enjoy the skin feel of the Paula's Choice 2% BHA liquid...

This was only the second BHA product that I ever tried and got this because I just don't enjoy the skin feel of the Paula's Choice 2% BHA liquid (which I used on/off for years), and this was recommended by fiddysnails who has a similar skin type and concerns to mine. I do like that this leaves no residue but I just don't find this to be very effective.

I have dry combo skin and very rarely deal with breakouts - the only reason I use BHA is to help keep the pores on my nose and chin clear of sebacious filaments. I also use peptides in my routine so I don't want a BHA that I need to use every day, as I haven't been able to find conclusive information on whether acids really make peptides less effective and for now choose to use them on alternate days. I find that this product when used every other day just isn't enough to keep my pores clear of gunk. Maybe my skin just responds better to salicylic acid than to betaine salicylate which this uses.
