ISDIN retinoid
Isdinceutics Retinal Intense Serum
A pharmaceutical-grade retinaldehyde serum with a genuinely innovative biphasic delivery system and an all-star supporting cast of bakuchiol, melatonin, niacinamide, and peptides. The ingredient quality is exceptional — among the best in the retinoid category. But at $185 for 1.7 oz, ISDIN is asking you to pay luxury prices for pharmaceutical credibility, and the fragrance and alcohol inclusions slightly undermine the clinical positioning.
