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. This ingredient comes from the pomegranate plant. It's rich in antioxidants (punicalagins, ellagic acid, and anthocyanins) that also give pomegranates their vivid color and reputation as a "superfruit". Research on skin cells, reconstructed skin models, and in small human trials is pretty encouraging, this extract: Ellagic acid has also been shown to slow the enzyme that makes pigment so it can help even out dark spots and uneven skin tone over time. A 2025 study where 60 women used either a pomegranate extract or a placebo backed this up; the pomegranate group had less redness, less extra pigment, and better-hydrated skin after UV exposure. Needless to say, this ingredient should not be replacing your sunscreen. Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation. You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
