Tranexamic Acid
Ingredient Info
Tranexamic acid is a synthetic amino acid derivative originally developed to reduce bleeding. In skincare, it works by suppressing melanin production and reducing inflammation, making it particularly useful for treating dark spots, melasma, and post-inflammatory discoloration.
Benefits
- Helps fade melasma and stubborn dark patches
- Reduces post-inflammatory hyperpigmentation (dark marks after acne or injury)
- Anti-inflammatory properties may help with rosacea and sensitive skin
- Works well in combination with other treatments
Potential concerns
- Oral/systemic forms have been associated with side effects; topical use is generally safer
- May take several weeks to show visible results
- Limited long-term safety data for topical use in skincare products
Science: Multiple clinical reviews confirm tranexamic acid's effectiveness in treating melasma and post-inflammatory hyperpigmentation, particularly when combined with other therapies. However, systemic (oral) use carries safety concerns, and most skincare applications remain topical, where safety data is still emerging.
