Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
This suits buyers who want the most completely disclosed antioxidant combination and accept the price. SkinCeuticals is the only brand in this ranking that publishes the percentage of all three key antioxidants: 15% L-ascorbic acid, 1% alpha-tocopherol and 0.5% ferulic acid. The formula is described as free of fragrance, alcohol, silicones and parabens, comes in a glass bottle with dropper, and is covered by US patent 7,179,841. The 2017 Al-Niaimi and Chiang review names ferulic acid as a stabiliser in SkinCeuticals formulations.
The brand states 37% improvement in firmness, 27% reduction in visible fine lines, 36% reduction in the appearance of wrinkles, up to 41% reduction of oxidative damage from UV, pollution and metals, and an effect lasting at least 72 hours. The page we read gives no participant numbers or durations for these figures, so we treat them as unverified brand claims.
Gaps: the full INCI list was not shown on the German page, pH is not published, and we saw no ratings on the manufacturer page; the product is not listed on Notino.de. At €184 (manufacturer price) it costs about twenty times The Ordinary's 23% suspension.

FAQ
Frequently asked questions
Why is C E Ferulic so often used as a benchmark?
It is the only product in this ranking whose maker publishes all three antioxidant percentages: 15% L-ascorbic acid, 1% alpha-tocopherol and 0.5% ferulic acid.
Are SkinCeuticals' efficacy figures independently verified?
Not on the page we read. The 37%, 27%, 36% and 41% figures appear without participant numbers, duration or a reference to a published paper.
