Detailed view
#1Water
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.
#1Avobenzone
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.
#2Caprylic/Capric Triglyceride
Caprylic/Capric Triglyceride is an emollient that also hydrates the skin without leaving a fatty film. When applied, the component feels smooth and light. In haircare products, it’s also used for hydrating purposes. It makes hair silky, lowers tangling, and makes hair smooth.
It’s safe for most people, except for people with allergic reactions to coconut or palm oil because these oils are usually used for producing the component.
#2Homosalate
#3Glycerin
Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.
The component is researched very well. Many scientific researches confirm the safety and the efficiency of the component.
#4Cetearyl Alcohol
Cetearyl Alcohol is used mostly for formulation purposes. It’s a very good emulsifier and emulsion stabilizer. It helps the ingredients mix better and it makes the product spread on your skin evenly. It also makes the product thicker. It doesn’t belong to harmful alcohols and it will not dry your skin.
#4Octocrylene
Octocrylene is an organic chemical sunscreen. It protects against UVA and UVB rays that can damage your skin or even lead to melanoma. It also stabilizes other sunscreen ingredients in a formulation and increases the water resistance of a product. It is approved by the FDA in concentrations of up to 10%. It’s not a very effective component on its own, that’s why manufacturers combine it with other chemical sunscreens.
Despite its effectiveness, there are some “cons” against the component. As with any other chemical sunscreen, it is absorbed and can be detected in blood. This doesn’t mean the component is harmful, but still… Octocrylene should also be used carefully by anyone who is breastfeeding because it can be found in breast milk.
Anyway, the component isn’t researched quite well despite its popularity. More studies are required to determine how safe the component is.

#5Dimethicone
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. What you should really know is that this component is difficult to wash off! So make sure you did proper cleansing after using it.
