Ingredients higher up in an ingredient list are typically present in a larger amount. Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!). It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome. On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive. Another perk of this ingredient is that it stays functional across a wide pH range (3-10). You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own. Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU. Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages. Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon. Silica, also known as silicon dioxide, is a naturally occurring mineral. It is used as a fine, spherical, and porous powder in cosmetics. Though it has exfoliant properties, the function of silica varies depending on the product. The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer. It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil. In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients. Titanium Dioxide (TD) is a mineral UV filter widely used in sunscreens and cosmetics. It's one of only two UV filters officially classified as "mineral" by regulatory agencies (the other being Zinc Oxide). A really common myth is that mineral filters work by reflecting UV light off your skin like tiny mirrors. They don't only do that; modern research shows TD protects mostly by absorbing UV radiation, the same way chemical filters do. When researchers measured this, reflection accounted for only about 4-5% of the protection (and less than SPF 2 on its own). The other ~95% comes from absorption: the UV photons hit the particle and their energy gets soaked up by its semiconductor band gap rather than bouncing off. So "reflects vs. absorbs" was never really the right way to split mineral from chemical filters. TD gives broad-spectrum
