Biore UV Aqua Rich Aqua Protect Lotion SPF 50+ PA++++ Ingredients Explained

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

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.

Ethylhexyl Triazone is a modern chemical sunscreen that protects from UV-B radiation.

It is the most effective of existing UV-B filters, as it provides the highest level of photo-stable absorption. It protects from the entire UV-B range (280 to 320nm), with it's highest level of protection at 314nm.

Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UVA absorber. It is formulated for high UVA protection (320-400 nm) and photostability.

DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%.

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.

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.

Dextrin Palmitate comes from the palmitic acid ester of Dextrin. It is used as an emulsifier and texture enhancer.

Emulsifiers help keep ingredients together. According to a manufacturer, dextrin palmitate helps create a low-viscosity gel texture.

Agar is the vegan substitute for animal-gelatin. It helps thicken and improve the texture of cosmetics.

Agar is an antioxidant. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells.

Cellulose is the main component of plant cell walls. It is used as an emulsifier, absorbent, and texture enhancer.

This ingredient has many functions:

We don't have a description for Polyvinyl Alcohol.

Acrylates Copolymer is used as a film-forming agent and texture enhancer.

After applied, Acrylates Copolymer forms a thin film cover that helps skin feel more soft. It can help sunscreens become more water-resistant.

We don't have a description for Polysilicone-3.

Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.

Royal Jelly Extract comes from a secretion made by worker honeybees. This secretion is white and described as creamy.

Royal Jelly contains antibacterial, anti-aging, and anti-inflammatory properties.

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.

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.

Disodium EDTA plays a role in making products more stable by aiding other preservatives.

It is a chelating agent, meaning it neutralizes metal ions that may be found in a product.

EDTA is the shortened name for ethylenediamine tetraacetic acid. It is a chelating agent and used to stabilize products.

Chelating Agents are used to prevent trace metal ions from binding to other ingredients. This can prevent unwanted reactions or changed efficacy of products.

BHT is a synthetic antioxidant. As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.

BHT also helps stabilize products and prevent them from degrading. Many products are sensitive to air and light. BHT prevents them from breaking down when exposed.

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.
