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!

Eucerin Sun Hydro Protect Ultra Light Fluid SPF50+ contains this as ingredient number 1.
Dibutyl Adipate is an emollient and solvent. It is created from butyl alcohol and adipic acid.
As a solvent, Dibutyl Adipate helps mix and disperse ingredients evenly.
Dibutyl Adipate is soluble in water and organic solvents. It does not absorb UV rays.

Eucerin Sun Hydro Protect Ultra Light Fluid SPF50+ contains this as ingredient number 8.
Alcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol and other additives. It has a low molecular weight and will evaporate quickly. This helps other ingredients become better absorbed and dry once applied.
Alcohol Denat. is volatile and may cause irritation. It helps draw out natural oils in skin and dry out your skin.
One study from 2005 found adding emollients to propanol-based sanitizer decreased irritation.
Alcohol is antibacterial by nature. This can help preserve products and increase their shelf life.
Other types of astringent alcohols include:

Also known as Avobenzone, this ingredient is a chemical sunscreen filter that provides protection in the UV-A range.
Avobenzone is globally approved and is the most commonly used UV-A filter in the world.
Studies have found that avobenzone becomes ineffective when exposed to UV light (it is not photostable; meaning that it breaks down in sunlight). Because of this, formulations that include avobenzone will usually contain stabilizers such as octocrylene.
However, some modern formulations (looking at you, EU!) are able to stabilize avobenzone by coating the molecules.
Avobenzone does not protect against the UV-B range, so it's important to check that the sunscreen you're using contains other UV filters that do!
The highest concentration of avobenzone permitted is 3% in the US, and 5% in the EU.

Eucerin Sun Hydro Protect Ultra Light Fluid SPF50+ contains this as ingredient number 4.
You might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.
Bemotrizinol has two peak UV absorption peaks ( 310 and 340 nm) and is able to absorb both UV-A and UV-B rays. Skin exposed to UV causes free-radical molecules to form. This ingredient works by preventing the UV from reaching your skin.
It is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.
Bemotrizinol is not approved in the US but is allowed in the EU, Australia, and Asia.
In fact, it is the most effective UV absorber at maximum concentration (measured by SPF) permitted by in the EU.
It is oil-soluble.

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and 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.

Eucerin Sun Hydro Protect Ultra Light Fluid SPF50+ contains this as ingredient number 31.
Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.
Silica is present naturally within the skin during collagen production and when reducing inflammation.

Eucerin Sun Hydro Protect Ultra Light Fluid SPF50+ contains this as ingredient number 11.
Glyceryl Stearate is a mix of glycerin and stearic acid.
Glyceryl Stearate is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.
As an emollient, it helps soften skin and supports barrier-replenishing ingredients.
In cosmetics, Glyceryl Stearate is often made from vegetable oils or synthetically produced. The human body also creates Glyceryl Stearate naturally.

Eucerin Sun Hydro Protect Ultra Light Fluid SPF50+ contains this as ingredient number 23.
Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, 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.
In the US, the alternative name for parfum is 'fragrance'. The term '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. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.
Depending on the blend, it can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Products use parfum often to give products a scent or cover up smells of different ingredients.
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.

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:
