Ingredient review
Laccase
INCI: Laccase
Laccase is a gentle enzyme that can help fade dark spots and even out skin tone without the harshness of some chemical brighteners.
In plain English
Laccase is an enzyme (a type of protein that speeds up chemical reactions) that can break down melanin, the pigment responsible for dark spots and uneven skin tone. It works like a natural eraser, gently lightening areas of hyperpigmentation over time. Because it's an enzyme, it's generally milder than strong acids or bleaching agents, making it a good option for sensitive skin types looking for gradual brightening.

Quick decision guide
Useful, but context matters
Laccase 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 Laccase.
- 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
Laccase is a copper-containing enzyme found in plants, fungi, and bacteria. In skincare, it is produced via biotechnology to ensure purity and consistency. It acts as a catalyst to oxidize various compounds, including melanin precursors.
How it works
Laccase works by oxidizing melanin intermediates, which reduces the formation of visible pigment in the skin. It also has antioxidant properties, helping to neutralize free radicals that can cause premature aging and dullness. When applied topically, it gently lightens existing dark spots and helps prevent new ones from forming.
Pros
Gentle brightening
Laccase works by breaking down melanin without the irritation often caused by stronger brighteners like hydroquinone or high-strength vitamin C, making it a good choice for sensitive or reactive skin.
Antioxidant support
Beyond fading spots, laccase also neutralizes free radicals, helping to protect skin from environmental damage that can lead to premature aging and dullness.
Cons and cautions
Slow results
Because laccase is a gentle enzyme, it works gradually. You may need to use it consistently for several weeks before seeing noticeable lightening of dark spots.
Variable effectiveness
The potency of laccase depends heavily on the formulation and concentration in the product. Not all products deliver the same level of brightening, so results can be inconsistent.
Best for
- People with mild to moderate hyperpigmentation or sun spots
- Those with sensitive skin who cannot tolerate strong brightening acids
Use caution if
- Anyone allergic to fungal or plant-derived enzymes (rare)
Usage tips
Safety summary
Laccase is considered safe for topical use in cosmetics. It has a low irritation and comedogenic risk, making it suitable for most skin types. Allergic reactions are rare but possible, especially in individuals with known sensitivities to fungal enzymes.
Research notes
Research on laccase in skincare is promising but still emerging. Studies show it can effectively reduce melanin production in lab settings and in small human trials, but larger, long-term studies are needed to fully confirm its efficacy and safety compared to established brighteners.
Common label clues
- Typical concentration
- 0.01% to 0.5% in leave-on products
- Regulatory status
- Laccase is generally recognized as safe for use in cosmetics when produced via biotechnology. It is not a drug ingredient and is not regulated as a treatment for medical conditions like melasma.
- Common uses
- Brightening serums, Dark spot correctors, Anti-aging treatments
- Environmental note
- Biotech production of laccase is considered more sustainable than extracting it from natural sources, as it reduces the need for harvesting fungi or plants.
Good to know
- Laccase is often derived from fungi like Trametes versicolor or from bacterial sources via fermentation.
- It is sometimes combined with other brightening ingredients like niacinamide or licorice root extract for enhanced effect.
