Mary KaySheer UV Defense Milk SPF 50+Ingredients

Titanium Dioxide is a very effective sunscreen. It belongs to physical sunscreens, meaning it reflects the UV rays like a mirror. The component is a mineral with white color. That’s why it’s also used in different powders as a pigment or brightener.

The component can be both safe and unsafe. It’s reported to be possibly carcinogenic to humans when inhaled. That’s why we don’t recommend using products where TiO2 is used in the form of powder and can be inhaled.

Sometimes it can be a nanoparticle. We recommend avoiding this form because it’s not researched well enough. A safer option is to use a non-nano form.

Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.

C12-15 Alkyl Benzoate is mostly used as formulation component. It gives the product a soft and silky but non-greasy feeling. As for the skin benefits, it's an emollient – it makes the skin softer and more hydrated. It also helps to kill bacteria and increase the product’s shelf life.

Dimethicone is the most popular silicone. It makes the skin softer and forms a film adding smooth and silky feeling. This film not only improves how the skin feels but also works as a protective barrier. It also improves the visual appearance of your skin by filling small wrinkles. That's why some people think dimethicone removes wrinkles. Actually, it does not. It's just a visual effect.

One of the most important characteristics of this component is that it helps to spread other ingredients evenly on the surface to provide good coverage. It's very important because you want all your skin cells to receive an equal proportion of the components.

Dimethicone is considered as safe, but remember that it is rather difficult to wash off! This may lead to clogged pores and acne if you use it too often and don't wash off quite well.

Stearic Acid doesn’t belong to aggressive acids. It’s a fatty acid that can be found in Shea Butter, Cocoa Butter, and many natural butters and oils. The component is mostly used for formulation purposes. It makes the product spread and feel better. It’s one of the most important fatty acids in our skin cells.

Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.

Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.

Sodium Benzoate doesn’t have any great skincare effects and is used for formulation purposes. It’s a corrosion inhibitor, fragrance ingredient, and preservative. It is not a broad-spectrum preservative and it’s used with other preservatives for good efficiency. It’s safe, but people with eczema or a history of skin allergies should use this component with attention.

Fragrance is a mix of chemical ingredients (usually 20-30 chemicals but up to 200 sometimes) that help the product to smell better. It can hide many bad things. Synthetic fragrances may contain many different chemicals, but manufacturers don’t want to reveal each of them for some reason and hide them behind the word "Fragrance".

Limonene provides a nice and fresh citrus scent. It can be found in many plants. It's used in cosmetics because of its low price and pleasant smell.

Disodium EDTA is an emulsion stabilizer and chelating agent. It deactivates the metal ions preventing them from reacting with other active ingredients. It improves the stability of a cosmetic formula and keeps the product’s consistency, texture, and pH unchanged. It doesn’t have any skincare effects and is used for formulation purposes only.

Tocopheryl Acetate is a form of Vitamine E. It’s used as an alternative to Tocopherol because it is more stable in the formulation. It has all the positive effects of Tocopherol plus better stability. It’s a brilliant component. It conditions and nourishes the skin helping it to resist aging. It also helps to protect the skin from the sun. High concentrations of Tocopheryl Acetate can lead to irritation and allergic reactions.

Potassium Sorbate is a preservative that increases the shelf life of the product. It’s a great alternative to parabens. That's why manufacturers like to use this component. It is safe in concentration of up to 10% but it is used in cosmetics in amounts of 1% or even lower.

Linalool gives the product a nice and fresh lavender scent. It can be found in many essential oils. It oxidizes during air exposure and becomes allergenic. It can lead to irritation causing problems for people with sensitive skin. The threat is even higher if the product was opened several months ago. In such products, more Linalool is oxidized.

Lecithin is a great emulsifier. It also has slight antioxidant activity, but it’s not enough if you are looking for a strong and effective anti-oxidant. Our skin cells contain Lecithin and that’s why this component will hardly cause any problems or negative reactions. It soaks in pretty fast and it’s accepted by skin cells very well.

Citronellol makes the product smell better. It’s one of the most frequently used fragrance ingredients in the world. It smells like a fresh cut of apple peel mixed with a citrus scent. It’s also used to enhance flower scent. It has slight anti-bacterial activity.

Beware! This component is in the list of potential allergens and can cause allergic contact dermatitis.

Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.

Geraniol is a fragrance ingredient that gives product a nice rose scent. That’s why it’s used by many manufacturers. In addition to its pleasant scent, it also provides an antifungal effect increasing the shelf life of a product. There are several ways of obtaining this ingredient but all of them are chemical.

Iron Oxides are colorants. They give different colors to the product: yellow, red, or black. Different scientific researches show that they are much safer than other organic colorants. That's because they are much more stable and they don’t provoke allergic reactions. Though they can be received from minerals organically, manufacturers don’t use natural Iron Oxides. They chemically synthesize them in a laboratory to get a pure component without extra chemicals.
