| Verdict | ISDIN's Hyaluronic Booster is the brand's quietly excellent hydration workhorse. Four molecular weights of hyaluronic acid (sodium hyaluronate, hyaluronic acid, hydrolyzed HA, sodium hyaluronate crosspolymer) layered with niacinamide (5% based on placement) and panthenol — that's the entire active stack. €49 for a four-weight HA serum is the kind of pricing that makes Spanish dermocosmetic globally interesting. | 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. |
