Introduction to Tranexamic Acid
What is Tranexamic Acid?
Tranexamic acid is a man-made compound that comes from the amino acid lysine. Though it’s more commonly used to control bleeding during surgeries or heavy periods, in the skincare world, it’s a rising superstar for brightening uneven skin tone and fading pigmentation.
Origin and Medical Use
Originally developed as an oral medication for controlling excessive bleeding, Tranexamic Acid’s impact on skin pigmentation was discovered incidentally—leading to its topical use in dermatology.
How Tranexamic Acid Works on Skin
Melanin Production and Hyperpigmentation
It works by interfering with the interaction between melanocytes (pigment-producing cells) and keratinocytes (skin cells). This blocks UV-induced melanin synthesis and helps reduce discoloration.
Anti-inflammatory Benefits
Inflammation is often the root cause of dark spots. It helps calm the skin and reduce the inflammatory response, especially helpful for acne-prone and sensitive skin types.
Compatibility With Other Actives
It’s a team player. You can combine it with Vitamin C, Niacinamide, and even Retinol—making it incredibly versatile.
Key Skin Concerns Treated by Tranexamic Acid
Melasma
This stubborn skin concern, often caused by hormonal changes, responds impressively to consistent use of Tranexamic Acid.
Dark Spots and Acne Scars
It lightens post-acne marks and sun-induced spots without causing irritation.
Post-inflammatory Hyperpigmentation
Especially common in deeper skin tones, this condition can be gently but effectively managed with regular use.
