Caffeine in summer: how to adjust

⏱ 1 min read
⚡ Quick answer: Using Caffeine in summer: the season brings heat, humidity, sweat and peak UV, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.

Using Caffeine in summer: the season brings heat, humidity, sweat and peak UV, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.

The workhorse of eye products. Caffeine constricts surface vessels temporarily, which softens the look of puffiness and shadow for a few hours — a real, genuinely short-lived effect, which is why it belongs in your morning routine.

What summer does to your skin

Heat, humidity, sweat and excess oil call for lightweight, fast-absorbing layers and a high, re-applied sunscreen.

How that changes Caffeine

Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. Caffeine works on dark circles & eye area, redness & sensitivity, sun damage & photoageing, and it is normally applied AM.
