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

- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservatives
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.
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.

HG acne scar serum
Initially, this serum had helped fade away most of my old acne scars. After while, I thought it didn't do anything more for my new acne growth. So I ditched this serum for about 3 months and tried other new niacinamide products. I REGRET it. Soon after, I got more and more whiteheads and acne. My skin texture becomes uneven and dry. The new acne scars couldn't fade away at all. Show more

Doesn't do much and it broke me out also I don't get the texture of this for a spot treatment
Initially I didn't like this but it was because the directions were not very clear to me. Even here on Skinsort it would line it up in the middle of the routine. Probably my fault in not using it right but now, I lather on a thick layer on any blemish or even on dark spots left from older acne before going to bed as the very last step. In the morning the blemishes are either gone or very much Show more
