Ingredients Explained
Hamamelis Virginiana Extract comes from the witch hazel plant.
Unless it is specified to be non-alcohol, many types of witch hazel ingredients are distilled in denatured alcohol.
Witch Hazel has astringent, anti-inflammatory, antioxidant, and antibacterial properties.
The tannin content of witch hazel constrict the appearance of pores by drying out proteins. Witch hazel water gets anti-inflammatory and antibacterial properties from its catechin and gallic acid content.
However, witch hazel may be skin-sensitizing due to the tannin and fragrance compounds.
North American Indigenous groups have used witch hazel to help treat inflammation for centuries.
Learn more about Hamamelis Virginiana ExtractAlcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol with other additives.
This ingredient gets a bad rep because it is irritating and drying - mostly due to its astringent property. Astringents draw out natural oils in tissue, constricting pores and leaving your skin dried out.
However, alcohol denat. is not all that bad.
Due to its low molecular weight, alcohol denat. tends to evaporate quickly. One study on pig skin found half of applied alcohol evaporated in 10 seconds and less than 3% stayed on skin.
This also helps other ingredients become better absorbed upon application.
Studies are conflicted about whether this ingredient causes skin dehydration. One study from 2005 found adding emollients to propanol-based sanitizer decreased skin dryness and irritation. Another study found irritation only occurs if your skin is already damaged.
Small amounts of alcohol are generally tolerated by oily skin or people who live in humid environments.
The rule of thumb is if this alcohol is near the end of an ingredients list, it will probably not affect your skin much.
Also...
This ingredient has antimicrobial and solvent properties.
The antimicrobial property helps preserve products and increase their shelf life. As a solvent, it helps dissolve other ingredients.
Other types of astringent alcohols include:

Those with sensitive skin or conditions may develop a rash when using this ingredient.

Tremella Fuciformis Extract comes from the tremella fuciformis mushroom, also known as snow mushroom or white jelly mushroom.
The snow mushroom has moisturizing and antioxidant properties.
Snow mushroom is rich in polysaccharides, giving it moisturizing benefits. As a humectant, snow mushroom helps draw moisture from the air to the skin. Polysaccharides are able to mimic our skin's natural carbohydrates to help the skin retain water.
Snow mushroom has been shown to help with anti-aging due to its antioxidants. It increases the presence of superoxide dismutase in our brain and liver. Superoxide is a by-product of oxygen metabolism. It left unregulated, superoxide causes cell damage. Thus, superoxide dismutase acts as an antioxidant to protect our living cells.
Another study from 2016 showed snow mushroom extract blocks the skin from creating melanin when exposed to UVB. Thus, it may help protect against the signs of aging from sun exposure. However, more studies are needed to confirm this. Another study from 2021 found snow mushroom to protect against UVA damage as well.
This white mushroom is native to Asian countries such as China, Korea, Japan, and Thailand. It is a common ingredient in traditional Chinese cuisine and medicine.

Snail Secretion Filtrate is the excretion from snails. It is an effective moisturizer and promotes collagen production.
A popular nickname for this ingredient is 'Snail Mucin'.
Snail mucin has numerous skin benefits:
On top of this, Snail Secretion Filtrate contains a variety of vitamins and minerals. These include copper peptides, Vitamin A, and vitamin E. Vitamins A and E are antioxidants. Antioxidants help fight free-radicals that damage skin cells.
Being cruelty-free means a brand does not experiment on animals. If you're worried about the well-being of the snails, we recommend looking more into the company of the product. Many brands have developed humane methods to collect snail mucin.
There is much debate on this subject. On one hand, this ingredient comes from an animal. On the other hand, many will argue the ingredient is naturally secreted (like a natural by-product) and therefore vegan. If you have reservations, you can look into Galactomyces Ferment Filtrate or Centella Asiatica Extract as alternatives.

It is a chelating agent, meaning it neutralizes metal ions that may be found in a product.
Disodium EDTA is a salt of edetic acid and is found to be safe in cosmetic ingredients.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.
The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
