Why blue caffeine
A focused patch format for puffy-looking, tired-looking eyes
Caffeine is used in Klairs eye care to help the eye area look less puffy and more awake. In this patch, 5,000 ppm caffeine is paired with niacinamide, peptides, 4GF, adenosine, azulene, and panthenol, so the measured results reflect the full formula and hydrogel patch routine, not caffeine tested alone.
Patch contact time
The 20 to 30 minute hydrogel step gives the caffeine-led formula time to sit closely on the eye area, making it a more focused option than a quick daily gel step.
Cooling synergy
Refrigerating the jar around 4°C can add a stronger cooling feel. This is a sensory routine tip, not a promise of identical results for every shopper.
