Caffeine vs. peptides vs. retinol — which should I pick?

Caffeine is best for puffiness and tired-looking eyes in the short term. Peptides target firmness and fine lines with low irritation risk, making them a good all-rounder. Retinol delivers the strongest anti-aging results over months but carries the highest irritation risk. Reviewers commonly stack them — for example, caffeine in the morning, peptides or retinol at night.
