Tranexamic Acid Serum
Supported by smaller clinical studies· Centuries of traditional use (Evidence grade B · Traditional use long-standing)Long-standing traditional staple
Topical serum with clinical-trial support for melasma
Why it may be relevant
A leave-on serum you smooth onto the darker areas, fitting a routine built around creams and serums applied right to the patches.

Azelaic acid
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Topical acid used for melasma and dark spots
Why it may be relevant
A naturally occurring acid applied as a cream, gel, or foam directly onto the patches — a natural fit for a topical-first routine.

I'd rather work on the pigment from the inside with supplements I take by mouth

Glutathione
Supported by smaller clinical studies (Evidence grade B · No traditional record)
Oral antioxidant studied for lightening pigmentation
Why it may be relevant
Glutathione taken internally is ideal for those looking to address pigmentation from within through a supplement.
Why try it
Explored in a systematic review as a skin-lightening agent, with limited and preliminary evidence in melasma.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results

Vitamin C
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Antioxidant supporting both skin and overall health
Why it may be relevant
Vitamin C plays a role both topically and systemically, fitting well for someone taking a combined approach to melasma.
Why try it

Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
General antioxidant support taken by mouth; this specific oral use for melasma has not been confirmed in controlled clinical trials.
Caution
High oral doses may cause digestive upset; caution with kidney conditions.

I'm drawn to hands-on, practitioner-led or holistic care (in-clinic or acupressure)

Acupuncture
Centuries of traditional use· Limited human trials so far (Evidence grade C · Traditional use long-standing)Long-standing traditional staple
Practitioner-delivered treatment for pigmentation
Why it may be relevant
Acupuncture is a professional, in-clinic option well suited for those seeking holistic or practitioner-led care.
Why try it
Explored in a Bayesian network meta-analysis of TCM therapies for melasma; the pooled trials are small and of limited quality, so the evidence base is early and low-certainty.
Dose or use
Work with a qualified, licensed practitioner; ask them how many sessions and how often are right for you.
Time to results
Typically 8–16 weeks
Key study
Network meta-analysis (2026, PMID 41995533): Comparative effectiveness of acupuncture, fire needle, and herbal therapies for melasma. Pooled several small TCM modalities; findings are low-certainty and not a substitute for standard care.
Caution
Seek a licensed acupuncturist; not suitable during pregnancy without clearance.
Postbiotic (heat-killed bacteria)
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · No traditional record)
Studied only as an add-on to in-clinic procedures
Why it may be relevant
The supporting research used this postbiotic strictly as an adjunct to professional IPL and microneedling, so it fits a practitioner-led plan — not a standalone remedy.
Why try it
Studied only as an add-on to professional IPL and microneedling, not on its own; any benefit cannot be attributed to the postbiotic by itself.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
RCT (2025, PMID 41347603): postbiotic formulation combined WITH intense pulsed light and microneedling for melasma. The postbiotic was an adjunct only; its standalone effect for melasma is unproven.
Caution
Check with your healthcare provider before starting, especially if you are pregnant or breastfeeding, take prescription medication, or manage a chronic condition.
SP6 (Sanyinjiao) - Spleen 6
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
TCM point traditionally used for hormonal balance
Why it may be relevant
A hands-on acupressure point you or a practitioner can work, fitting the holistic, practitioner-led path alongside acupuncture.
Why try it
Melasma is often hormone-driven, and SP6 — where the Spleen, Liver, and Kidney meridians meet — is traditionally used in TCM for menstrual and hormonal regulation.
Dose or use
Locate about three finger-widths above the inner ankle bone; apply firm, steady pressure for 1–2 minutes per side.
Time to results
Varies; traditionally used as an ongoing supportive practice
Key study
Traditionally used in TCM for hormonal and menstrual balance; this specific use for melasma has not been confirmed in controlled clinical trials.
Caution
Traditionally avoided during pregnancy; seek a licensed practitioner if pregnant or trying to conceive.

Cordyceps
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · Traditional use recognised)Recognised traditional use
Herbal extract studied within a topical cream for melasma
Why it may be relevant
Cordyceps has been studied in a topical cosmetic formulation, fitting naturally into a skin-applied routine.
Why try it
In a 12-week trial a cordyceps-containing cream, used alongside oral tranexamic acid, performed about as well as a hydroquinone regimen; because both groups also took oral tranexamic acid, the benefit can't be credited to cordyceps on its own.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
RCT (2025, PMID 40590148): Effect of a New Skin-Lightening Cosmetic Containing Cordyceps Extract in the Treatment of Melasma: A Clinical Trial. Both arms received oral tranexamic acid; the cordyceps cream was comparable to a hydroquinone regimen, so cordyceps' independent effect is not established.
Caution
Check with your healthcare provider before starting, especially if you are pregnant or breastfeeding, take prescription medication, or manage a chronic condition.
Niacinamide (Nicotinamide)

Vitamin D Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low levels are often reported in melasma
Why it may be relevant
Checking and correcting a possible shortfall is an internal, root-cause step for a supplement-based approach taken by mouth.
