Butyl Methoxydibenzoylmethane Homosalate Ethylhexyl Salicylate Octocrylene Water Butyloctyl Salicylate Glycerin Dimethicone Poly C10-30 Alkyl Acrylate Vp/Eicosene Copolymer Cetearyl Alcohol Niacinamide Sodium Stearoyl Glutamate Ammonium Polyacryloyldimethyl Taurate Hydroxyacetophenone Phenoxyethanol Tocopheryl Acetate Panthenol Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate Xanthan Gum Propanediol Oryza Sativa Extract 1,2-Hexanediol Sodium Hyaluronate Active Ingredients: Butyl Methoxydibenzoylmethane, Homosalate, Ethylhexyl Salicylate, Octocrylene Inactive Ingredients: Water, Butyloctyl Salicylate, Glycerin, Dimethicone, Poly C10-30 Alkyl Acrylate, Vp/Eicosene Copolymer, Cetearyl Alcohol, Niacinamide, Sodium Stearoyl Glutamate, Ammonium Polyacryloyldimethyl Taurate, Hydroxyacetophenone, Phenoxyethanol, Tocopheryl Acetate, Panthenol, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Xanthan Gum, Propanediol, Oryza Sativa Extract, 1,2-Hexanediol, Sodium Hyaluronate 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 vitamin C) and some UV filters (like octocrylene and Tinosorb S) can meaningfully improve its stability in a formulation. The maximum allowable concentration according to regulation is 3% in the US + Canada, and 5% in the EU, Australia, China, Korea, and ASEAN countries. It has a well-support safety profile: a comprehensive 2025 review found minimal toxicity with no evidence of carcinogenicity. Overall, avobenzone is a safe and regulated ingredient used in sunscreen for over 40 years. Homosalate is an oil-soluble organic UVB filter that has been a sunscreen staple for decades. Its job is to absorb UVB rays (~295-315 nm) and protect your skin against sunburn, This is one of the more photostable organic UV filters; it holds up pretty well under UV and a 2022 quantum-chemistry study found it stays stable in sunlight. It's actually so reliable that formulators often pair it with shakier ingredients like oxybenzone and avobenzone. Formulators also use it to help dissolve the other UV filters into the oil phase. One thing to keep in mind: "stable" isn't the same as "strong". On its own, homosalate is actually a pretty weak UV filter so it's better off as a helpful team player that helps boost overall SPF protection. The safety picture is a bit nuanced but not scary. This ingredient has a long track record of being gentle and regulators agree it isn't an irritant; EU's Scientific Committee on Consumer Safety found that homosalate is not considered a skin irritant and doesn't raise eye-irritation flags either. There's talk about homosalate because your skin absorbs a little bit of it into your bloodstream. A 2020 FDA-backed study found homosalate showed up in people's blood levels at the level where the FDA decides to double check. The EU's Scientific Committee on Consumer Safety (SCCS) also found small amounts in blood and breast milk. They estimated that about 5% of what you apply gets absorbed through the skin. Due to the debate about whether it might mess with hormones, the SCCS recommended a maximum limit of 0.5% in most products of 7.3% in face creams/pump sprays. One important thing to keep in mind: in the US, Homosalate is currently labeled "non-GRASE" by the FDA. This sounds alarming but really just means the FDA wants more data to confirm it's safe. It's not confidently saying this ingredient is harmful. As of now, homosalate is still completely legal and widely used while that research gets done.
