| Verdict | ISDIN's retinaldehyde powerhouse — a step above retinol in the vitamin A hierarchy. Retinal (retinaldehyde) converts to retinoic acid in one step instead of two, meaning faster results with less irritation than prescription tretinoin. ISDIN pairs it with HPR (hydroxypinacolone retinoate) for a dual-retinoid approach, plus bakuchiol as a botanical synergist and hyaluronic acid for hydration. The Spanish derm brand's most serious anti-aging product. | Mesoestetic's antioxidant serum — a C+E+Ferulic formulation from the brand's clinical line that targets the same territory as SkinCeuticals CE Ferulic but with the Spanish aesthetic-channel's clinical rigour. Pure L-ascorbic acid (the most potent and evidence-backed form of vitamin C) is paired with ferulic acid (which stabilises vitamin C and boosts its photoprotective efficacy by 8x, per the Duke University research that defined this combination), pure tocopherol (vitamin E, the lipid-phase antioxidant), and resveratrol for additional polyphenol support. Niacinamide and panthenol round out the formulation for barrier support. At ~$75 for 30ml, premium pricing — but the C+E+Ferulic combination is the gold standard of antioxidant serums, and Mesoestetic's version adds resveratrol for extra breadth. |
