Tranexamic acid (TXA):
What is it, what are the benefits and
which skin types does it suit best?

Taking the skincare world by storm, tranexamic acid is a trending hyperpigmentation hero. Keep reading for everything you need to know about this brightening powerhouse ingredient.

What is Tranexamic Acid in Skincare?

Tranexamic acid is an active ingredient that is able to help block the processes within the skin which form uneven tone and dark spots. Think visibly brighter, more clarified skin with a more even tone.

What does Tranexamic Acid do to the skin?

Tranexamic acid is a pigment-suppressor, meaning it can block the overproduction of melanin within the skin. When melanin is overproduced in certain areas of the skin, it can result in uneven skin tone, hyperpigmentation and dark spots.

What are the key benefits?

  • Visibly evens & brightens skin tone
  • Minimises the appearance of post-blemish marks & dark spots
  • Gentle & soothing on skin
  • Skin-barrier supporting
  • Anti-Ageing


How does it work?

Tranexamic acid provides powerful brightening action, by helping to prevent the formation of dark spots on the skin. It works by reducing the activity of an enzyme called ‘tyrosinase’, the main enzyme responsible for creating melanin while blocking the transfer of melanin to upper layers of the skin, where it becomes visible as hyperpigmentation on the complexion.

Tyrosinase can go into overdrive when faced with sun exposure, overproducing melanin which can result in uneven patches of tone and dark spots. Combined with wearing sunscreen everyday, tranexamic acid can help to reduce the appearance of hyperpigmentation and visibly brighten targeted areas of the skin.

Tranexamic acid also has a secondary benefit of providing a powerful and specific anti-inflammatory action. It reduces inflammation in the skin by inhibiting the release of proinflammatory signalling molecules. This is particularly useful in preventing post-inflammatory erythema, a.k.a. the pink or red marks that are left on your skin post-breakout or injury.

What skin concerns can Tranexamic Acid help to address?

  • Evenness of skin tone
  • Stubborn dark spots
  • Post-blemish imperfections
  • Overall skin radiance

  • It can target these concerns through its abilities as a pigment-suppressing ingredient.

    Tranexamic acid is also an anti-inflammatory, meaning it is super gentle and soothing whilst targeting skin tone concerns.

Frequently Asked Questions about Tranexamic Acid

What’s the difference between tranexamic acid and other exfoliating acids such as AHAs and BHAs?

While all these ingredients are classed as acids, tranexamic acid is not considered an exfoliating acid like AHAs and BHAs. Tranexamic acid is an amino acid derivative, that's where the ‘acid’ comes into the name. While exfoliating acids such as salicylic acid or glycolic acid literally exfoliate the skin, resulting in smoothness and less congestion, tranexamic acid is able to help inhibit the process of dark spots and discolouration forming.
