What Is Tranexamic Acid?
Tranexamic Acid is a rising star in skincare, especially for tackling skin discolouration and uneven tone. Derived from the amino acid lysine, it’s been used for years as an oral medication to help with heavy menstrual bleeding. More recently, Tranexamic Acid has gained popularity as a gentle yet effective topical treatment to fade various types of pigmentation, including melasma. Research even suggests its brightening power can rival that of hydroquinone, the gold-standard brightening ingredient, without the harsh side effects. Beyond targeting dark spots, Tranexamic Acid also supports the skin’s youthful appearance, making it a versatile addition to many skincare routines.
How Does Tranexamic Acid Work to Treat Hyperpigmentation?
Tranexamic Acid helps even out your skin tone by interrupting the way your skin produces Melanin, the pigment responsible for colour. When your skin is exposed to ultraviolet (UV) light from the sun or tanning beds, it produces more of an enzyme called Plasmin. This excess Plasmin sets off a chain reaction that causes the skin to make more Melanin than usual, leading to dark spots and uneven patches.
What makes Tranexamic Acid special is its ability to block this process. It stops Plasmin and its precursor, Plasminogen, from triggering extra Melanin production. By interrupting these pathways, Tranexamic Acid effectively reduces the appearance of surface discolourations, making your complexion look brighter and more balanced.
What Types of Pigmentation Does Tranexamic Acid Help With?
Tranexamic Acid is a versatile ingredient that targets various types of skin discolouration, helping to both prevent new dark spots and fade existing ones.
Here are the main types of pigmentation Tranexamic Acid can help with:
- Melasma: Mask-like brown or grey patches around the cheeks, forehead, and upper lip. It can worsen during pregnancy or sun exposure, and Tranexamic Acid is especially effective at treating it.
- Sun spots (solar lentigines): Small brown spots caused by UV damage that build up over time.
- Post-inflammatory hyperpigmentation (PIH): Dark marks left after inflammation or injury, like acne. Tranexamic Acid fades these marks on all skin tones, especially deeper ones.
- Uneven skin tone: Patchy discolouration or redness that dulls your complexion. Tranexamic Acid helps reduce redness and smooth your skin tone for a brighter look.
How Does Tranexamic Acid Compare to Other Brightening Ingredients?
Tranexamic Acid is gentle yet effective, especially for sensitive skin, with a targeted action on pigmentation by blocking melanin production and inflammation. Here’s a quick look at how it compares to some popular brighteners:
- Vitamin C: Brightens and protects skin; pigmentation benefits are secondary.
- Niacinamide: Evens skin tone and reduces redness; supports pigmentation improvement and multitasks.
- Hydroquinone: Highly effective but often irritating; Tranexamic Acid offers a gentler alternative.
- Retinoids: Promote cell turnover but can irritate; Tranexamic Acid works more specifically on pigment pathways with less irritation.
Using Tranexamic Acid alongside Vitamin C or Niacinamide can boost brightening effects while maintaining skin tolerance.
Who Is Tranexamic Acid Best For?
Tranexamic Acid is a versatile and gentle ingredient suitable for almost anyone tackling pigmentation issues like dark spots and uneven skin tone. It works well for all skin types and tones, including sensitive or pigmentation-prone skin such as Fitzpatrick types III to VI. Plus, it’s non-comedogenic, so it won’t clog pores—perfect for dry, oily, or combination skin.
Unlike exfoliating acids, Tranexamic Acid doesn’t increase sun sensitivity, making it safe to use alongside other actives like Vitamin C and retinol.
- Reduce irregular pigmentation from melasma, acne scars, inflammation, or sun damage
- Support a brighter, more radiant complexion
- Improve skin dullness caused by glycation

Is Tranexamic Acid Safe for Daily Use?
Yes, Tranexamic Acid is generally safe to use every day, and consistency is key if you want to see real results. Daily application is often recommended to gradually fade discolouration and even out skin tone.
To build it into your routine safely:
- Start slowly: If you’re new to the ingredient, try using it every other day at first. If your skin shows no signs of irritation, you can increase to daily use.
- Check the concentration: Most products contain 2–5% Tranexamic Acid, which is considered safe for regular use. Always follow the product’s specific instructions.
- Decide on frequency: Depending on the formula, you may be able to apply it once or even twice a day, morning and/or evening.
Because it’s not an exfoliating acid, Tranexamic Acid tends to be well-tolerated across all skin types, including sensitive skin. Just remember to pair it with sunscreen during the day to protect your progress.
Are There Any Side Effects or Risks?
Tranexamic Acid is safe for most skin types, but some people may experience mild side effects, especially when starting out:
- Mild irritation, such as redness, itching, or tingling, that usually fades
- Dryness or flaking, especially if combined with other actives
- Rare allergic reactions like swelling or hives — stop use and consult a professional
Most side effects are mild and temporary. If discomfort continues, seek advice from a skincare expert or GP.
Is It Safe to Use During Pregnancy or Breastfeeding?
Tranexamic Acid is generally considered safe for topical use during pregnancy and breastfeeding, as it’s minimally absorbed through the skin. It’s often chosen to help with pigmentation changes that can happen during pregnancy, sometimes referred to as the “pregnancy mask”.
However, to be on the safe side, it’s always best to consult with your midwife or obstetrician before introducing any new active ingredients into your skincare routine.
Can Tranexamic Acid Be Used With Other Active Ingredients?
Yes! Tranexamic Acid is gentle and works well with many other active ingredients. While it’s called an acid, it doesn’t exfoliate like AHAs or BHAs—it specifically targets pigmentation without irritating your skin.
Here’s how it pairs with popular activities:
- Vitamin C – Brightens and protects; combines well with Tranexamic Acid to boost skin radiance and even tone
- Niacinamide – Soothes and improves skin tone; enhances brightening effects
- Retinol or Bakuchiol – Helps with fine lines and discolouration; safe to use with Tranexamic Acid when you support your skin barrier properly
- AHAs/BHAs – Gently exfoliate and clear pores; can be used alongside Tranexamic Acid, but introduce gradually to avoid irritation
- Licorice Root & other plant extracts – Natural brighteners and soothing agents; complement Tranexamic Acid nicely for a more even complexion
Remember, keeping your skin barrier strong with hydration and moisturisers is key when using multiple actives.
Where Does Tranexamic Acid Fit in My Routine?
How you use Tranexamic Acid depends on the product type — whether it’s a serum, cream, or spot treatment. Generally, apply it after cleansing and toning. If it’s a serum, layer it before moisturiser. Use it once or twice daily for best results.
For brightening, it pairs well with Vitamin C in the morning (follow with sunscreen) and with retinoids or niacinamide in the evening.
If you’re unsure how to fit Tranexamic Acid into your routine or combine it with other products, Face Dr’s team of Skincare Experts is here to help. Reach out for a free consultation and personalised advice.
How Long Before I See Results?
Results from Tranexamic Acid usually start to show within 2 weeks, but it can take up to 1 month, or sometimes a little longer, to see the full effect. Keep in mind that factors like your skin type, the concentration used, and consistency in your routine all influence how quickly you’ll notice improvements.
Should I Stop Using It Once Pigmentation Fades?
It’s generally recommended to continue using Tranexamic Acid even after your pigmentation has improved to help maintain the results. Since it works by slowing down melanin production, stopping completely may allow pigmentation to return over time.
