Tranexamic Acid

Tranexamic acid (TXA) is a synthetic amino acid derivative originally used in medicine to reduce bleeding. Today, it is also widely used in skincare and cosmetics, especially for dark spots and uneven skin tone.

• Appearance: white crystalline powder
• Solubility: water-soluble
• Use: medical & cosmetic (very different doses)

What Is Tranexamic Acid Used For?

Medical use (under doctor supervision)

• Controls heavy bleeding (surgery, trauma, heavy menstrual bleeding)
• Helps reduce blood loss

Skincare & cosmetic use (low concentrations)

• Reduces dark spots & hyperpigmentation
• Helps with melasma
• Improves uneven skin tone
• Calms inflammation and redness
• Enhances overall skin brightness

In cosmetics, it is not used to stop bleeding—only for skin tone correction.

How It Works

In skincare, tranexamic acid:

• Blocks pathways that trigger excess melanin (dark pigment)
• Reduces inflammation that causes discoloration
• Helps stop new dark spots from forming

👉 This makes skin look clearer and more even over time.
