Micro-Dose Anti-Aging Retinol Serum

This serum features excellent airless pump packaging and a high-quality 'buffer' complex of ceramides and peptides that aligns with research for minimizing irritation. While it uses pure retinol (a well-validated active) and has product-specific clinical data, it loses points for not explicitly disclosing the retinol percentage on the packaging and being priced significantly higher than competitors with similar or higher potencies.
