| 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. | Segle Clinical's Triple Retinoid Serum is the Madrid pharmacy brand's PM showpiece — three retinoid forms in one bottle: Retinol (0.3%), Retinaldehyde (0.15% — the metabolic intermediate that converts faster than retinol), plus chlorella extract for marine retinoid support. Niacinamide buffers, Centella + licorice root extracts soothe. €64 for a triple-retinoid stack that competes with much pricier US alternatives. |
