Science
Mechanism of Action
Krameria Triandra Root Extract exerts its effects by enhancing the skin's barrier integrity through the promotion of essential lipid and protein synthesis, which consequently minimizes transepidermal water loss and boosts resistance to environmental irritants. Its rich composition of tannins and proanthocyanidins delivers notable astringent properties, leading to visible skin tightening, reduced pore appearance, and a moderation of oil production. Functioning as a robust antioxidant, it effectively neutralizes free radicals, thereby protecting against oxidative stress and premature aging. The extract also demonstrates anti-inflammatory capabilities that alleviate redness, irritation, and sensitivity. Furthermore, its bioactive compounds possess antibacterial and antimicrobial efficacy, which can help in reducing breakouts and inhibiting microbial growth on the skin. It also provides photoprotective advantages by mitigating oxidative stress, scavenging reactive oxygen species (ROS), and preventing lipid peroxidation in keratinocytes exposed to UV radiation.

Key findings
- 01 A 2% topical formulation demonstrated a reduction in sebum production in preliminary lab assessments.
- 02 In human keratinocyte cultures exposed to UVB (50 mJ/cm2), concentrations from 2.5 to 20 µg/ml dose-dependently minimized oxidative damage and preserved cell viability.
- 03 At 10 µg/ml, it nearly fully maintained keratinocyte viability even under higher UVB doses (300 mJ/cm2).
- 04 Showcased potent antioxidant activity, with an IC50 of 0.28 ± 0.04 µg/ml, significantly surpassing alpha-tocopherol (IC50 6.37 ± 0.41 µg/ml) in inhibiting hemolysis.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety assessment, and its status with the Scientific Committee on Consumer Safety (SCCS) remains unreviewed. While the FDA lists it as a natural flavoring substance, a specific cosmetic safety status is not established. Allergic contact dermatitis has been reported, indicating a rare but known risk of sensitization when used externally.
