#1Alcohol Denatured
![Bad for dry skin](https://skinsignal.com/api/web/image/layout/dry_bad.png?w=30&q=50)
Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.
It’s one of the most harmful alcohols used in skincare. You should use it carefully, especially if you have dry skin. It removes oily barrier from the surface of your skin making it less protected and causing dryness. We advise you to pay attention to the position of this component in a formulation. If it stays below the 6th position it will hardly harm your skin. We also recommend testing the product first before application. If you feel a “cooling effect” it means the product contains a lot of alcohol and it's better to be careful with it.
#2Octocrylene
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.

#3Ethylhexyl Salicylate
#3Zinc Oxide
![Good for oily skin](https://skinsignal.com/api/web/image/layout/oily_good.png?w=30&q=50)
Zinc Oxide is a great physical sunscreen, meaning it deflects the UV rays. It’s the only natural mineral sun protector recommended by the FDA for babies. It’s good for sensitive skin because it’s less irritating than chemical sunscreens.
It has very nice spectrum protection. It helps to protect from UVA I, UVA II, and UVB and nowadays it’s the broadest range of sunscreen used in cosmetics. In other words, it’s brilliant in its league.
The negative side is that it can feel heavy on the skin. It can leave a slight whitish tint on the surface of the skin and some people may not like this. Keep in mind that it’s relatively easy to wash off, so it’s better to use water-resistant sunscreens if you are swimming.
#4Butyloctyl Salicylate
#4Avena Sativa (Oat) Bran Extract
#5Homosalate
#5Betaine
![Good for dry skin](https://skinsignal.com/api/web/image/layout/dry_good.png?w=30&q=50)
Betaine is used a lot in “organic” skincare products. It is a good moisturizer that not only hydrates the skin but also strengthens the cell membrane. This helps to lower the water loss over time. It also softens the skin and reduces irritation and redness. It’s often used at a 3-5% concentration depending on the product.
