Can Rejuran Salmon DNA Help Treat Melasma?
Melasma can be one of the most frustrating forms of facial pigmentation. It may improve and then return, darken after sun or heat exposure, and respond differently from one person to another.
As interest in Rejuran, polynucleotides, PDRN, and “salmon DNA” treatments has grown, patients are increasingly asking:
Can Rejuran actually help melasma?
The answer is nuanced.
Rejuran may potentially support overall skin quality and may have a role in a comprehensive pigmentation treatment plan, but it should not be considered a proven stand-alone treatment or cure for melasma.
At AIVI Aesthetics, we approach melasma conservatively because aggressive treatment can sometimes make pigmentation worse.
What Is Rejuran?
Rejuran is an injectable skin treatment containing polynucleotides (PN) derived from highly purified salmon DNA fragments.
You may also hear treatments in this category described online as:
- Salmon DNA injections
- Polynucleotide injections
- PN skin boosters
- PDRN treatments
- Rejuran Healer
- Rejuran skin booster
Although PN and PDRN are related terms, they shouldn’t automatically be treated as identical products or formulations.
Rejuran is primarily used internationally as a skin-quality treatment rather than a traditional volumizing filler.
The goal is generally to improve characteristics such as:
- Skin texture
- Hydration
- Fine lines
- Overall skin quality
- Skin resilience
It doesn’t provide the structural volume expected from traditional dermal fillers.
Is Rejuran FDA Approved?
This is important for U.S. patients.
Rejuran is not currently FDA-approved in the United States.
Although polynucleotide treatments have become popular internationally, particularly in parts of Asia, international use doesn’t mean a product has FDA approval for use in the United States.
Patients considering any injectable treatment should understand exactly:
- What product is being used
- Its regulatory status
- What it is being used for
- Potential benefits
- Potential risks
- Available alternatives
What Is Melasma?
Melasma is an acquired pigmentation disorder that commonly causes symmetrical brown or gray-brown patches on areas such as the:
- Cheeks
- Forehead
- Upper lip
- Nose
- Chin
It is particularly common in women and in people with darker skin phototypes, although anyone can develop it.
Melasma isn’t simply caused by “too much pigment.”
It is a complex condition influenced by several factors.
What Causes Melasma?
Common contributors and triggers include:
Sun exposure
Ultraviolet radiation is one of the most important triggers for melasma.
Even relatively small amounts of repeated exposure can contribute to recurrence.
Visible light
Visible light can also contribute to pigmentation, particularly in darker skin types.
This is one reason tinted sunscreens containing iron oxides are often incorporated into melasma management.
Hormones
Melasma frequently occurs during:
- Pregnancy
- Hormonal changes
- Use of certain hormonal medications
This is why melasma has historically been called the “mask of pregnancy.”
Heat
Some patients report worsening with significant heat exposure.
Inflammation and irritation
Skin irritation may contribute to pigmentation, particularly in patients prone to post-inflammatory hyperpigmentation.
Genetics
Family history can also play a role.
Because several mechanisms may be involved simultaneously, melasma often requires long-term management rather than a single treatment.
Does Rejuran Treat Melasma?
At this point, Rejuran shouldn’t be described as a primary or established treatment for melasma.
There is scientific interest in the potential effects of polynucleotides and PDRN on skin repair, inflammation, and tissue regeneration, but that doesn’t automatically mean Rejuran injections have been proven to reliably clear melasma.
Some patients may notice improvements in overall:
- Skin quality
- Texture
- Hydration
- Luminosity
- Appearance of uneven tone
Those changes can make the complexion appear healthier and more even.
But that’s different from demonstrating that Rejuran directly suppresses the biological mechanisms responsible for melasma.
Can Polynucleotides Help Hyperpigmentation?
This is an area of emerging research.
Preclinical and early clinical research involving PN/PDRN has explored effects involving:
- Tissue repair
- Inflammatory signaling
- Fibroblast activity
- Skin regeneration
- Oxidative stress
There is also growing interest in how these mechanisms might influence pigmentation.
However, promising biological mechanisms aren’t the same as high-quality evidence demonstrating that injectable Rejuran reliably treats melasma in humans.
Patients should be cautious when social-media claims move faster than clinical evidence.
Does Rejuran Lighten Dark Spots?
Not necessarily.
“Dark spots” can describe several different conditions, including:
- Melasma
- Post-inflammatory hyperpigmentation
- Solar lentigines
- Freckles
- Pigmentation after acne
- Pigmentation following procedures
These aren’t all treated the same way.
Rejuran shouldn’t be viewed as a general pigment eraser.
If pigmentation is your primary concern, the first step is determining what type of pigmentation you actually have.
Rejuran vs. Traditional Melasma Treatments
For melasma, treatments with substantially more established clinical use may include:
- Daily broad-spectrum sunscreen
- Tinted sunscreen containing iron oxides
- Hydroquinone when appropriate
- Azelaic acid
- Retinoids in appropriate patients
- Combination topical therapy
- Tranexamic acid in carefully selected patients
- Certain chemical peels
- Carefully selected energy-based treatments
Treatment selection depends on skin type, medical history, pregnancy status, previous treatments, and severity.
Rejuran shouldn’t replace appropriate sun protection and evidence-based pigment management.
Why Sunscreen Matters More Than Rejuran for Melasma
If you have melasma, one of the most important parts of treatment happens every day at home.
Consistent photoprotection is critical.
A comprehensive strategy may include:
- Broad-spectrum SPF 30 or higher
- Regular reapplication
- Hats and physical sun protection
- Avoiding unnecessary prolonged sun exposure
- Tinted sunscreen with iron oxides when appropriate
This matters because UV and visible light can stimulate pigmentation even after successful in-office treatment.
You can invest in excellent procedures and still struggle with recurrent melasma if daily photoprotection is inconsistent.
Rejuran vs. Hydroquinone for Melasma
These treatments serve very different purposes.
Hydroquinone
Hydroquinone is a topical depigmenting medication with established use in treating hyperpigmentation, including melasma.
It directly targets melanin production through inhibition of tyrosinase activity.
Rejuran
Rejuran is a polynucleotide injectable primarily associated with skin-quality improvement.
It shouldn’t be described as a substitute for hydroquinone or other established pigment-directed therapies.
Some patients may have reasons not to use hydroquinone, while others may use it strategically under medical guidance.
Treatment should be individualized.
Rejuran vs. Tranexamic Acid for Melasma
Tranexamic acid has become an important topic in melasma treatment.
Depending on the patient and clinician, it may be considered in topical, oral, or other treatment approaches.
Oral tranexamic acid isn’t appropriate for everyone because medical history and thromboembolic risk must be evaluated.
Rejuran and tranexamic acid shouldn’t be considered interchangeable.
Tranexamic acid is used specifically because of its effects on pathways involved in melasma, while Rejuran is primarily considered a regenerative skin-quality treatment.
Can Rejuran Be Combined With Microneedling?
Treatment combinations need to be planned carefully.
Microneedling can be used in some pigmentation treatment strategies, but patients with melasma require particular caution because inflammation itself can sometimes worsen pigmentation.
More aggressive treatment isn’t automatically better.
Treatment intensity should account for:
- Skin type
- Melasma activity
- History of PIH
- Current skincare
- Recent sun exposure
- Skin-barrier health
At AIVI Aesthetics, we don’t intentionally create excessive inflammation simply because a patient wants faster pigment correction.
What About RF Microneedling and Melasma?
RF microneedling may be appropriate for other concerns such as texture, acne scars, fine lines, or laxity.
But when someone has melasma, treatment planning becomes more nuanced.
Melasma can be sensitive to:
- Heat
- Inflammation
- Irritation
That doesn’t mean every patient with melasma must avoid every energy-based treatment.
It means the indication, settings, skin type, and treatment goals need to be considered carefully.
Can Rejuran Be Combined With Chemical Peels?
Potentially, but timing and peel selection matter.
Chemical peels can play a role in treating pigmentation, but aggressive exfoliation can also trigger post-inflammatory hyperpigmentation in susceptible skin.
A treatment plan may separate procedures rather than stacking everything into one appointment.
The goal with melasma isn’t to make the skin peel as much as possible.
It’s to improve pigmentation without provoking unnecessary inflammation.
What About Lasers for Melasma?
Laser treatment for melasma requires careful patient selection.
Some laser and light-based treatments can temporarily improve pigmentation but may also cause:
- Rebound pigmentation
- Post-inflammatory hyperpigmentation
- Recurrence
This doesn’t mean lasers can never be used.
It means melasma shouldn’t be treated as if it’s simply a sunspot that can always be “lasered off.”
If you have melasma, tell your provider before undergoing laser or energy-based treatment.
Is Rejuran Better for Post-Inflammatory Hyperpigmentation?
Rejuran shouldn’t automatically be considered a treatment for PIH either.
Post-inflammatory hyperpigmentation develops after inflammation or injury to the skin.
Examples include pigmentation following:
- Acne
- Burns
- Picking
- Procedures
- Eczema
- Irritation
Because the cause and depth of pigmentation vary, treatment should be individualized.
Improving overall skin health may complement a pigmentation plan, but pigment-specific therapy may still be necessary.
Is Rejuran Good for Darker Skin Tones?
Polynucleotide treatments have attracted interest partly because they aren’t pigment-targeting lasers.
However, having darker skin doesn’t automatically make every injectable treatment risk-free.
Any procedure involving injections can produce:
- Inflammation
- Bruising
- Swelling
- Irritation
And inflammation can contribute to PIH in susceptible patients.
Patients with Fitzpatrick IV–VI skin types should still receive individualized treatment planning.
Can Rejuran Cure Melasma?
No.
Melasma is generally considered a chronic, recurrent pigmentation condition.
Even treatments that successfully improve it don’t guarantee that it will never return.
Common triggers such as:
- Sun
- Visible light
- Hormonal changes
- Heat
- Inflammation
can contribute to recurrence.
A better goal is often long-term control rather than promising a permanent cure.
How Many Rejuran Treatments Would I Need?
There isn’t an established Rejuran protocol specifically for treating melasma.
Rejuran skin-quality protocols often involve a series of treatments, but the appropriate number and interval depend on:
- Product
- Treatment indication
- Skin condition
- Treatment area
- Patient response
- Overall treatment plan
We shouldn’t tell patients that “three or four treatments will treat melasma” because that isn’t an established melasma treatment protocol.
What Results Should I Expect From Rejuran?
When Rejuran is being considered for skin quality rather than as a direct melasma treatment, realistic goals may include improvement in:
- Overall skin texture
- Hydration
- Fine lines
- Skin quality
- General complexion
Any improvement in pigmentation should be considered in the context of the patient’s entire melasma treatment program.
Frequently Asked Questions
Does Rejuran remove melasma?
Rejuran isn’t an established stand-alone treatment or cure for melasma. It may support overall skin quality, while pigment-specific treatments and photoprotection remain important.
Does salmon DNA lighten skin?
Polynucleotide treatments shouldn’t be marketed as skin-bleaching injections. Some patients may notice a brighter or more even complexion as skin quality improves, but that isn’t the same as proven melasma clearance.
Is PDRN good for melasma?
PDRN is being studied for several regenerative and inflammatory effects, including possible applications involving pigmentation. However, more clinical evidence is needed before it can be considered an established melasma treatment.
Is Rejuran good for hyperpigmentation?
It may complement a broader skin-quality and pigmentation plan, but the appropriate treatment depends on the type of hyperpigmentation.
Can Rejuran make melasma worse?
Any procedure that causes inflammation or irritation has the potential to influence pigmentation in susceptible skin. Appropriate technique, patient selection, and aftercare are important.
Is Rejuran better than a laser for melasma?
Neither should automatically be considered “better.” Rejuran and lasers work very differently, and laser treatment of melasma requires careful selection because some energy-based procedures can worsen or trigger recurrent pigmentation.
Can I combine Rejuran with hydroquinone?
A provider may incorporate different treatments into a comprehensive pigmentation plan when appropriate. The exact regimen should depend on your skin, medical history, tolerance, and type of pigmentation.
Is Rejuran FDA approved for melasma?
No. Rejuran isn’t FDA-approved in the United States, including for the treatment of melasma.
Treating Melasma at AIVI Aesthetics
At AIVI Aesthetics in Agoura Hills, we don’t approach melasma by simply trying to remove pigment as aggressively as possible.
Melasma often requires a long-term, multimodal strategy that may involve:
- Daily photoprotection
- Pigment-regulating skincare
- Prescription treatments when appropriate
- Skin-barrier support
- Carefully selected procedures
- Avoiding unnecessary inflammation
- Maintenance therapy
Rejuran may be considered as part of a broader skin-quality strategy, but we won’t promise that a salmon-DNA injection will cure melasma.
Our goal is to understand why your pigmentation is occurring, what may be triggering it, and which treatments make sense for your individual skin.
AIVI Aesthetics serves Agoura Hills, Westlake Village, Thousand Oaks, Calabasas, Oak Park, and surrounding Conejo Valley communities.
