What's inside
Ingredients Explained
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. If you see this, drink a glass of water. Remember to stay hydrated!
Learn more about WaterThis ingredient is also known as Neroli Hydrosol or bitter orange blossom water. It is an aromatic water made by distilling the flowers of the bitter orange tree.
Because it is water that contains very small amounts of volatile aromatic compounds, this ingredient is more gentle than essential oil.
Some of the naturally occurring components have been studied for antioxidant and calming effects. However, like other fragrant plant waters, it can cause irritation in fragrance-sensitive skin.
Learn more about Citrus Aurantium Amara Flower WaterThis ingredient is also known as tea tree leaf water or tea tree hydrosol. It functions as an antimicrobial, anti-sebum, astringent, and tonic ingredient.
You can think of it as a gentler, water-version of tea tree oil.
Its star active is terpinen-4-ol, a broad-spectrum antimicrobial.
The water-soluble compounds of tea tree have been shown to calm inflammation by roughly 50% in vitro (with Terpinen-4-ol driving this).
Terpinen-4-ol has also demonstrated strong inhibitory activity against Propionibacterium acnes and Staphylococcus aureus.
Before slathering on tea tree water, just know concentrations under 5% are considered more suitable and safer than higher concentrations.
The European Medicines Agency recognizes tea tree-derived ingredients as having well-established use for mild acne and small superficial wounds.
It's a well-researched and skin-friendly option for oily or acne-prone skin.
As with most actives, patch testing is a good idea if your skin leans sensitive.
Learn more about Melaleuca Alternifolia Leaf WaterPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
