Lycopene is a carotenoid pigment found in tomatoes and other red fruits that acts as a potent antioxidant, helping to neutralize free radicals and protect skin from oxidative stress and UV-induced damage. In topical and dietary use it is studied for its photoprotective and anti-aging potential.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or redness | Rare | Mild localized reaction possible with topical application, often related to formulation rather than lycopene itself. |
| Allergic contact dermatitis | Very rare | Isolated sensitivity reactions reported; uncommon for carotenoids. |
| Skin discoloration (orange tint) | Very rare | High dietary or topical carotenoid exposure can rarely cause temporary yellow-orange skin tone (carotenoderma). |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
