Mulberry Extract
BotanicalBrighteningNaturalAlso known as: Morus Alba Extract, White Mulberry Extract
Mulberry extract is derived from the root bark, leaves, or fruit of Morus alba (white mulberry), a deciduous tree in the Moraceae family with a long history in traditional Chinese and Korean medicine. The extract is rich in stilbenes, flavonoids, and benzofuran derivatives, with the most pharmacologically significant compounds being mulberroside A, oxyresveratrol, and kuwanon G. Mulberry extract is one of the most effective natural tyrosinase inhibitors available, with studies showing that mulberroside A and its metabolite oxyresveratrol can inhibit tyrosinase activity with potency comparable to or exceeding that of arbutin and kojic acid. Tyrosinase is the rate-limiting enzyme in melanin biosynthesis, and its inhibition reduces the production of both eumelanin and pheomelanin. In addition to its brightening properties, mulberry extract provides antioxidant and anti-inflammatory effects that address the broader cascade of events leading to hyperpigmentation.
Routine placement
Serum · AM & PM
Time to results
4-8 weeks for visible benefits
Provides potent skin-brightening effects through inhibition of tyrosinase, the key enzyme in melanin synthesis. Helps fade dark spots, melasma, and post-inflammatory hyperpigmentation with consistent use. Evens overall skin tone by reducing melanin overproduction in hyperactive melanocytes. Offers antioxidant protection through oxyresveratrol and flavonoid compounds that neutralize free radicals. Provides anti-inflammatory support that addresses the inflammatory triggers underlying many forms of hyperpigmentation. Demonstrates a favorable safety profile compared to synthetic depigmenting agents such as hydroquinone.
Incorporate mulberry extract into your routine through serums, essences, or targeted treatment products designed for hyperpigmentation. Apply to cleansed skin in the evening, or both morning and evening for accelerated results. Layer under moisturizer and always use broad-spectrum sunscreen during the day, as unprotected sun exposure will counteract brightening efforts. For best results, combine with other complementary brightening ingredients such as niacinamide, vitamin C, or alpha-arbutin. Consistent use for a minimum of eight to twelve weeks is generally needed to observe significant improvements in pigmentation. Products with mulberry extract listed in the first half of the ingredient list are more likely to contain effective concentrations.
Research published in the Journal of Cosmetic Dermatology demonstrated that mulberry extract inhibited tyrosinase activity by approximately 50% at concentrations achievable in topical formulations, comparable to kojic acid at equivalent doses. A comparative in vitro study found that oxyresveratrol was 32 times more potent than arbutin in tyrosinase inhibition. Clinical studies have shown that mulberry-containing formulations significantly reduced the Melanin Index and improved subjective assessments of skin brightness after 8 to 12 weeks of use. A study in the International Journal of Molecular Sciences characterized the multiple mechanisms by which mulberry phenolics inhibit melanogenesis, including direct tyrosinase binding, downregulation of MITF, and reduction of oxidative stress in melanocytes. However, one of the challenges with mulberry extract is the variability in active compound concentration depending on the plant part used and extraction method. Standardization of preparations to specific oxyresveratrol or mulberroside A content would improve clinical reproducibility.
- Known allergy to Moraceae family plants
Cautions
Mulberry extract is generally well tolerated with a low incidence of adverse reactions. However, those with known allergies to Moraceae family plants (which includes figs and breadfruit) should patch test before use. While mulberry extract is considered safer than hydroquinone, discontinue use if excessive lightening, irritation, or uneven pigmentation changes occur. As with all brightening agents, sun protection is essential during use to prevent rebound hyperpigmentation. Limited data exist on the safety of concentrated mulberry extract during pregnancy, so consultation with a healthcare provider is advisable.
What does Mulberry Extract do for skin?
Mulberry Extract is used in skincare primarily as a botanical ingredient. Its effects depend on concentration and formulation. Check the benefits section above for specific details.
Is Mulberry Extract safe for sensitive skin?
Mulberry Extract is generally well-tolerated, but sensitivity varies by individual. Start with a patch test if you have reactive skin, and introduce gradually into your routine.
Can I use Mulberry Extract every day?
For most skin types, daily use is appropriate at standard concentrations. If you experience any irritation, reduce frequency to every other day.
