Ingredient review
Kojic Dipalmitate
INCI: Kojic Dipalmitate
A gentler, more stable version of kojic acid that targets dark spots without the irritation or instability of the original.
In plain English
Kojic dipalmitate is a modified form of kojic acid, a natural brightener derived from mushrooms or fermented rice. The modification makes it more stable in formulas and less likely to irritate skin, while still helping to fade hyperpigmentation like sun spots or post-acne marks. Unlike plain kojic acid, it can be used in oil-based products and doesn't turn brown as quickly when exposed to air.

Quick decision guide
Useful, but context matters
Kojic Dipalmitate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Kojic Dipalmitate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Kojic dipalmitate is a semi-synthetic compound created by combining kojic acid with palmitic acid (a fatty acid). This chemical tweak makes the ingredient oil-soluble and more stable, so it lasts longer in products and is less prone to oxidation and irritation.
How it works
It works by inhibiting tyrosinase, an enzyme needed to produce melanin (the pigment that colors skin). By slowing melanin production, it helps fade existing dark spots and prevents new ones from forming as intensely. Because it's oil-soluble, it can penetrate deeper into the skin's lipid layers compared to water-soluble kojic acid.
Pros
Gentler brightening
Kojic dipalmitate is much less likely to cause stinging or redness compared to plain kojic acid, making it a better option for sensitive skin.
Better formula stability
It doesn't oxidize or discolor as quickly as kojic acid, so your product stays effective and looks fresh longer on the shelf.
Cons and cautions
Milder effect
Because it's a derivative, it may be less potent than pure kojic acid, so you might need more time or a higher concentration to see results.
Limited research
Most studies focus on kojic acid itself; fewer clinical trials specifically examine kojic dipalmitate's efficacy and long-term safety.
Best for
- Anyone with sun spots, age spots, or post-acne marks
- People who find kojic acid too irritating or unstable
Use caution if
- Those with very sensitive or reactive skin should patch test first
Usage tips
Safety summary
Kojic dipalmitate is considered safe for cosmetic use at typical concentrations (0.5–2%). It has low irritation and comedogenic potential. The Cosmetic Ingredient Review (CIR) has not issued a specific safety assessment for this derivative, but kojic acid is generally recognized as safe in low concentrations.
Research notes
Clinical evidence for kojic dipalmitate is limited but promising. Studies on kojic acid show it effectively inhibits tyrosinase and reduces hyperpigmentation. The dipalmitate form is designed to improve stability and reduce irritation, but direct comparative studies are sparse.
Common label clues
- Typical concentration
- 0.5% to 2%
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and many other regions. Not classified as a drug ingredient.
- Common uses
- Serums, Moisturizers, Spot treatments, Face masks
- Environmental note
- Kojic dipalmitate is derived from natural sources (kojic acid from fungi) and modified synthetically. Its environmental impact is not well-documented, but it is not known to be bioaccumulative.
Good to know
- Kojic dipalmitate is often used in 'brightening' or 'dark spot corrector' products alongside other actives like niacinamide or vitamin C.
- It is considered safe for use during pregnancy, but always consult your doctor for personal advice.
