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

- 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.
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.

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 (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.
