Quick answer
Glutathione or tranexamic acid: which is better? For melasma, tranexamic acid has stronger evidence, and dermatologists often use it in creams, serums and, for some patients, prescription tablets. Glutathione is a gentler antioxidant that may help general dullness and uneven tone. Topical forms of both can be used together; tranexamic acid tablets need a doctor.
Tranexamic acid (TXA) has become one of the most talked-about ingredients for melasma. Here’s how it compares with glutathione, and when each makes sense.
How each one works
Tranexamic acid was first used in medicine to reduce bleeding. In skin, it appears to block signals that tell pigment cells to make more melanin, especially those triggered by UV and inflammation. It may also calm the tiny blood vessels that play a part in melasma.
Glutathione is an antioxidant. It may slow tyrosinase, the enzyme that makes melanin, and shift pigment towards a lighter type, while protecting skin from oxidative stress. See what is glutathione?
Side-by-side comparison
| Glutathione | Tranexamic acid | |
|---|---|---|
| Best known for | Dullness, uneven tone, antioxidant care | Melasma and stubborn pigmentation |
| Evidence for melasma | Limited; a supportive extra | Stronger; many studies, widely used by dermatologists |
| Topical forms | Creams, serums | Serums and creams, often 2–5% |
| Oral forms | Supplements; check with a doctor | Prescription only, and not for everyone |
| Irritation risk (topical) | Low | Low |
An important safety point about TXA tablets
Oral tranexamic acid affects blood clotting. It isn’t suitable for people with a history of blood clots, certain heart conditions, or those on some hormonal medicines, and it should only be taken under a dermatologist’s prescription and monitoring. Never take TXA tablets for skin without a doctor. Topical TXA doesn’t carry the same concerns.
Can you use them together?
Yes, topically. A TXA serum in the morning under sunscreen (or at night) and a glutathione night cream work in different ways and are often combined. Introduce one product at a time and patch test.
Which should you choose?
- Melasma: see a dermatologist. TXA is often part of the plan, with glutathione as an optional extra. See glutathione for melasma.
- General dullness or tan: a glutathione cream plus daily sunscreen is a good start.
- Acne marks: both can help brown marks. See glutathione for acne marks.
Common questions
Can I buy tranexamic acid tablets without a prescription?
Don’t. Even if a pharmacy sells them, their clotting effects make medical supervision essential.
Which works faster?
Both take weeks. Expect to judge results at 8–12 weeks, with strict sun protection.
