Before you use it
Topical caffeine causes no systemic stimulant effects. The appearance effect in eye creams is real but transient — not a structural change. Also used in SPF formulas for its antioxidant synergy.
On the label
Listed as "caffeine" in INCI. In eye creams, often paired with peptides (look of firmness) and hyaluronic acid (hydration). Look for a meaningful position in the list — not a trace addition.
