Paullinia Cupana (guarana) seed extract is a botanical ingredient rich in caffeine, tannins, and polyphenols, used in skincare for its antioxidant, vasoconstrictive, and toning properties. It is commonly included in anti-cellulite, eye, and firming formulations to reduce puffiness and provide skin-conditioning effects.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation or redness | Uncommon | May occur with high concentrations or on sensitive skin, partly due to tannin and caffeine content. |
Contact dermatitis | Rare | Allergic reactions to botanical components reported infrequently in patch-test contexts. |
Dryness or tightness | Rare | Possible from astringent tannins, especially in leave-on products. |
Stinging or transient discomfort | Rare | More likely near the eye area or on compromised skin barrier. |
