Ingredients higher up in an ingredient list are typically present in a larger amount. Allantoin is a soothing ingredient known for its protective and moisturizing properties; it's basically a quiet workhorse ingredient you can find in a huge range of cosmetics. Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity. Research shows it can encourage your skin cells to turn over and renew by stimulating keratinocyte and fibroblast proliferation. It also has mild keratolytic properties to help loosen and shed dead skin cells without being harsh. Studies also suggest allantoin can help calm inflammation by dialing down some of the chemical signals your skin sends out when it is irritated. This ingredient is typically used in the 0.1-0.5% range, and the FDA recognizes it as a skin protectant in OTC products up to 2%. Overall, allantoin is a wonderful addition to most routines; it is stable across a wide pH range (~4-8), works well with other ingredients, and is considered non-sensitizing/non-irritating. Fun fact: Allantoin is naturally occurring in comfrey root, beets, chamomile, and wheat sprouts. Our bodies even produce it as a byproduct of uric acid metabolism. This ingredient is also known as oxybenzone, and is one of the older organic UV filters. Its main job is sitting in the oil phase and soaking up UV photons (primarily UVB with some short-wave UVA II range). At low levels, oxybenzone also pulls double duty as a formula stabilizer that protects fragrance and colorants from fading in the light. On concentrations: So why did the EU cut back on how much you can use? It comes down to absorption. Oxybenzone passes through skin more easily than other filters. When the FDA tested sunscreens, every filter showed up in people's blood above the level where the agency wants extra safety testing done. But Oxybenzone showed up at by far the highest levels of the bunch. To be clear, the FDA's point was that we need more research and not that the ingredient is dangerous. They also said to keep using sunscreen. That high absorption, plus some animal studies pointing to effects on reproduction, is why EU regulators labeled Benzophenone-3 a hormone disruptor in 2025. An official classification is expected to follow in 2026. It's also the most common photoallergen among sunscreen filters so it's a more frequent cause of contact/photoallergic dermatitis than most alternatives. Places like Hawaii and Palau have also banned it over coral-reef concerns. Also known as Avobenzone, this ingredient is an oil-soluble used to absorb the full spectrum of UVA rays (peak 357 nm). It's one of the most effective UVA filters available but has a major caveat of photostability: avobenzone is susceptible to photodegradation. This means it can lose efficacy when exposed to sunlight without the help of a stabilizing agent. Studies show antioxidants (like vitamin E or vit
