What you get: A brightening serum that visibly fades dark spots, hyperpigmentation, and post-blemish marks for a clearer, more radiant complexion.

How to feel: Lightweight, smooth gel texture that sinks in fast without residue.

When to use: Use this tranexamic acid serum the AM and PM, after cleansing and your hydrator. Massage onto face and neck. Follow with moisturiser, and SPF in the AM.

  • All skin types
  • Sensitive skin
  • Pregnancy & breastfeeding

  • Hyperpigmentation
  • Uneven skin tone
  • Dark spots

The Science of Tranexamic Acid

Why Tranexamic Acid is the Gentle Giant of Dark Spot & Hyperpigmentation Treatments

Unlike harsh acids or aggressive peels, Tranexamic Acid works by:
- Blocking inflammation pathways that trigger excess pigment
- Preventing melanin overproduction at the source
- Protecting skin barrier while treating discoloration
- Suitable for all skin tones and types

The INKEY Difference: Our 2% concentration is the sweet spot - strong enough for results, gentle enough for daily use. Combined with Acai Berry antioxidants and stable Vitamin C, it's your complete dark spot and hyperpigmentation solution.

Reviews Summary
Customers say this serum has a lightweight, gel-like texture that absorbs quickly into the skin. Many reviews mention visible improvements in skin appearance over time, particularly for dark spots. The formula feels smooth and works well under other skincare products. While some notice results within weeks, others report needing longer to see changes. Several note packaging issues with the pump mechanism. A few users experienced skin sensitivity, though most find it gentle. Common feedback includes its non-sticky finish and easy integration into skincare routines.

    Tranexamic Acid Serum

    This product definitely faded the dark circles under my eyes. These dark circles literally appeared overnight when I turned 60, 5 years ago.. I actually dislike them more than my deep forehead troughs (I can sort of cover them with my hair. Up until these dark circles, I looked fairly young for my age . I haven’t found a makeup that hides them so I’m left with trying to fade them at least a little. Any advice greatly appreciated. In the meantime, this is the Product that has done the best job for me. Disappointingly, it always seems to be sold out. Therefore it loses one star

    Hi Morele, thank you for your honest feedback - we completely understand how frustrating it is when a product doesn't last as long as you'd expect.
    A little tip that might help with Tranexamic Acid, a few drops is really all you need per application. If you're finding it running out quickly, it's worth double checking the amount you're using as a little genuinely goes a long way with this one! 💙
