Tranexamic Acid FAQs

What is tranexamic acid and what does it do?

Tranexamic acid, often written TXA, fades dark spots and patchy pigmentation. It calms the signals that tell skin to make extra pigment, so it is useful for marks after breakouts, sun spots and stubborn patches.

Who is it for, and do I need it?

It suits anyone with dark spots or uneven tone, including skin that gets irritated by stronger brighteners. If your tone is already even, you probably do not need it.

How do I use it in my routine?

Apply a TXA serum or cream after cleansing, morning or night, then moisturise. Daily SPF is essential, because sun undoes the work. SkinCeuticals Advanced Brightening UV Defense Sunscreen SPF50 40ml combines TXA with SPF50 in one step.

Can I use it with retinol, vitamin C or other acids?

Yes. TXA works well alongside niacinamide, vitamin C and retinoids, and is gentle enough to use with most routines. Some products, such as Neostrata Post Acne Mark Correcting Serum 30ml, already combine it with other brighteners.

Is it suitable for sensitive skin, and during pregnancy?

It is usually well tolerated, even by sensitive skin. There is little research on TXA skincare in pregnancy, so check with your doctor first.
