When it comes to skin brightening, kojic acid has long been a popular choice for treating pigmentation, dark spots, and overall uneven skin tone. However, the original form of kojic acid has its limitations, particularly when it comes to stability and skin irritation. Enter Kojic Acid Dipalmitate (KAD)—a derivative that offers all the benefits of kojic acid with enhanced stability and lower irritation potential.
What is Kojic Acid?
Kojic acid is a natural compound derived from fungi and certain plants. It has been used for decades in skincare due to its tyrosinase-inhibiting properties, which help to reduce the production of melanin in the skin. This makes it effective in treating hyperpigmentation such as dark spots, melasma, and uneven skin tone. By interfering with the melanin production process, kojic acid can help lighten skin and even out complexion, making it a staple in many skin-brightening formulations.
However, despite its effectiveness, kojic acid has some significant downsides, particularly its instability and its potential to irritate the skin, especially when used in high concentrations or for prolonged periods.
The Problem with Traditional Kojic Acid
While kojic acid is widely used in skin-lightening products, it has some key drawbacks:
-
Instability: Kojic acid is highly sensitive to heat, light, and air, which can cause it to degrade quickly, losing its effectiveness. This makes kojic acid-based products less reliable over time, especially when stored improperly or exposed to light.
-
Skin Irritation: Due to its high acidity, traditional kojic acid can be harsh on sensitive skin, leading to irritation, redness, dryness, or even a stinging sensation. This is especially problematic for those with delicate or reactive skin types who are prone to post-inflammatory hyperpigmentation (PIH).
-
Short Shelf Life: Because of its instability, products containing kojic acid often have a shorter shelf life, making it difficult to maintain consistent results.
What is Kojic Acid Dipalmitate (KAD)?
Kojic Acid Dipalmitate is a modified, esterified form of kojic acid that is both oil-soluble and significantly more stable than traditional kojic acid. Unlike the original form, KAD does not degrade as easily when exposed to light or heat, making it a more reliable and long-lasting brightening agent. KAD also has a gentler effect on the skin, making it a better choice for those with sensitive skin or those prone to irritation.
Here are the key differences between Kojic Acid and Kojic Acid Dipalmitate (KAD):
How Kojic Acid Dipalmitate Works for Brightening
KAD works in much the same way as regular kojic acid, by inhibiting the enzyme tyrosinase—the enzyme responsible for melanin production. By blocking this enzyme, KAD reduces the production of excess melanin, which is responsible for dark spots and uneven skin tone.
However, because of its improved stability and slower absorption, KAD offers controlled, sustained release, providing longer-lasting brightening results without overwhelming the skin.

The Clinical Evidence Behind Kojic Acid Dipalmitate
The dermat’s choice for reducing marks & dark spots
Tyrosinase is a key enzyme that is responsible for melanogenesis in melanoma & melanocytes. The inhibition of tyrosinase will greatly affect the melanogenesis process & melanin production in the skin, thus reducing the appearance of marks, dark spots, discolouration, uneven skin tone & dullness.
Kojic acid dipalmitate is a safe skin brightening agent used to treat hyperpigmentation, as per a study* published in the National Library of Medicine in 2012, on the depigmenting effect of kojic acid & kojic acid esters.
*In-vitro test conducted in a lab to assess the safety, efficacy & effects of skincare formulations
As per a popular study on the cosmetic applications of kojic acid dipalmitate that was published in MDPI in 2024, it was found that kojic acid dipalmitate at 2%. potency is both efficacious & safe for treating melasma. It did not induce skin irritation & contributed to skin brightening, as evidenced by a reduction in hyperpigmentation observed in 51-57% of the subjects.
