Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Humectant, Masking, Skin Conditioning

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

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Skin Conditioning, Solvent

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

  • Humectant, drawing moisture into the skin
  • Emollient, helping to soften skin
  • Solvent, dispersing and stabilizing formulas
  • Preservative booster, enhancing the antimicrobial activity of other preservatives 
Skin Conditioning

Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Skin Conditioning, Skin Protecting, Soothing

Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.

Some studies have shown this ingredient can promote wound healing with higher concentrations.

Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.

This one right here - my holy grail.

Bought it with the mindset that I would use it once a week, as a deep moisturizer treatment, ended up using it almost every night.

I do have an oily T-zone but so far, no breakouts. If I do get some, I'll stop using it so frequently but I'm still going to try to find a way to insert it on my routine now and then, because seriously, the skin is SO soft Show more

If you’re super duper mega oily and live in hot, humid weather, then this toner is definitely for you. It’s incredibly effective in terms of oil control. I have combination skin, and this toner really helps manage the oiliness in my T-zone.

It’s doing such a great job at oil control that even my cheeks, which aren’t oily, ended up feeling dry. Clearly, it’s really effective at controlling oil.

This brown liquid is so golden! It keeps my skin pretty matte/satin-ish all day. I live in Florida, so its always humid and hot for the most part and with my combo skin, I tend to have a shinier t-zone daily. So once I started to realize that my t-zone wasnt looking overly shiny after a few days after first use I checked the bottle again and saw that it has sebum control. Love!
