Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Isntree Chestnut BHA 0.9% Clear Toner contains this as ingredient number 1.
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.

1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.
In products that are water-based, this ingredient can help stabilize perfumes and fragrances. It can also help make the texture of products softer and more smooth.

My first chemical exfoliator. Great as an introduction for beginner or sensitive skin. Works well for a couple of months and then it didn't give the same effect as it used to. Help reduce blackheads, bumps, and prevent hormonal aches.

When I first used this, it made my skin tingle ever-so-slightly before revealing the smoothest skin ever. The ever-present texture (closed comedones) on my forehead and cheeks have diminished greatly because of this. I only use it at night because AHA can cause sensitivity to sunlight!

HG exfoliating toner
I use this only at night twice a week. On first use, I didn't really feel the good effects straight away but I woke up to clearer complexion. But on second use, my skin felt so smooth and silky the next day when I woke up. It is also really gentle on my sensitive skin and didn't cause any irritations.
