INCI - Full Breakdown
Avobenzone is the only chemical UV-protection component with a broad spectrum coverage. It can help to block both UVA I and UVA II rays. It's safe and it is allowed to use at a 3% concentration in the USA and a 5% concentration in the EU countries.
There is one problem: avobenzone loses efficiency when exposed to the sun. If you are outside, it loses 36% of its ability to block UV rays an hour after application. That's why it's recommended to reapply sunscreen every 2 hours.
Octinoxate is an effective sun protector that absorbs UV-B rays mostly. That means it can help to protect the skin from burns and from cancer. It’s also a solvent for other sunscreen components. This helps manufacturers to make products less oily.
Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.
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.
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.
Dipropylene Glycol is a solvent, emulsifier, viscosity decreasing, and masking agent. It helps to extract useful chemicals from plants and leaves, making natural components in a product more effective. It also helps to hydrate the skin. Considered safe for health and doesn't irritate the skin in common concentration.
