At 83.5% concentration, the Mary\u0026amp;May Citrus Unshiu and Tremella Fuciformis Serum uses this heritage botanical at a dose that makes its tyrosinase-inhibiting and antioxidant activity functionally meaningful rather than decorative, paired with 9.7% Tremella Fuciformis (Snow Mushroom) Extract, a natural Hyaluronic Acid alternative with comparable or superior water-holding capacity for simultaneous deep hydration.

Clinical studies demonstrate meaningful reduction in hyperpigmentation over four to eight weeks of consistent use. At 83.5%, the Flavonoid concentration is present at a level consistent with the concentrations demonstrating efficacy in cosmetic research.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e9.7% Tremella Fuciformis (Snow Mushroom) for Deep Hydration:\u003c\/strong\u003e Snow Mushroom Extract contains natural polysaccharides with comparable or superior water-holding capacity to Hyaluronic Acid, delivering visible plumping and surface smoothing while supporting the skin barrier. It is well-tolerated across all skin types including sensitive and reactive, making it a highly compatible hydrating partner for the brightening active.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAntioxidant Protection Against Pigmentation Triggers:\u003c\/strong\u003e The high Flavonoid content of Citrus Unshiu provides antioxidant protection against the UV-induced and environmental free radical damage that is one of the primary triggers for tyrosinase activation and melanin overproduction, addressing both existing pigmentation and the conditions that cause it to recur.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGentle Vitamin C Alternative for Sensitive Skin:\u003c\/strong\u003e Citrus Unshiu delivers Vitamin C precursors and Flavonoids that produce brightening activity through a mechanism gentler than L-Ascorbic Acid, making this serum appropriate for sensitive and reactive skin that cannot tolerate conventional Vitamin C serums at effective concentrations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Choose the Mary\u0026amp;May Citrus Unshiu and Tremella Fuciformis Serum?\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e83.5% Versus the Typical Under 5%:\u003c\/strong\u003e Citrus Unshiu appears in many K-beauty formulas as a supporting ingredient at concentrations below 5%, where its brightening contribution is minimal. At 83.5%, Mary\u0026amp;May uses it as the primary active — a formulation commitment that distinguishes this serum from brightening products that include Citrus Unshiu for positioning appeal rather than meaningful efficacy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrightening and Hydration as Complementary Rather Than Competing Functions:\u003c\/strong\u003e Most high-concentration brightening serums are not deeply hydrating, and most deeply hydrating serums are not brightening. The Citrus Unshiu and Snow Mushroom pairing addresses both in a single daily formula that suits skin dealing with dullness and dehydration simultaneously, which is the typical presentation in dry or mature skin dealing with hyperpigmentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEWG Green-Grade Verified for Sensitive Skin:\u003c\/strong\u003e Free from artificial fragrance, parabens, alcohol, and common allergens.

Citrus Unshiu Flavonoids work more gradually through tyrosinase inhibition and antioxidant activity, but with a significantly better tolerability profile and without the oxidation instability that makes L-Ascorbic Acid serums progressively less effective as they age. For sensitive or reactive skin that cannot use conventional Vitamin C consistently, Citrus Unshiu at 83.5% provides a reliably effective and stable daily brightening alternative.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this in the morning?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Follow with SPF in the morning, as any brightening active increases photosensitivity slightly, and UV exposure is one of the primary causes of hyperpigmentation recurrence.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How long before I see results on dark spots?\u003c\/strong\u003e\u003cbr\u003eA: Improved radiance is typically noticeable within two to three weeks. Meaningful reduction in dark spots generally requires six to eight weeks of consistent daily use, reflecting the skin's natural cell turnover cycle.\u003c\/p\u003e\n\n\u003cp\u003eThe Mary\u0026amp;May Citrus Unshiu and Tremella Fuciformis Serum demonstrates what becomes possible when a heritage brightening botanical is used at the concentration it was always capable of rather than the concentration that makes a label claim.\u003c\/p\u003e\n\n\u003cdiv class=\"sn-explore-more\"\u003e\n\u003ch3\u003eExplore more\u003c\/h3\u003e\n\u003cp\u003eDiscover more \u003ca href=\"\/collections\/arbutin\"\u003earbutin\u003c\/a\u003e brightening, target \u003ca href=\"\/collections\/pigmentation\"\u003epigmentation\u003c\/a\u003e, or browse the full \u003ca href=\"\/collections\/mary-may\"\u003eMary \u0026amp; May\u003c\/a\u003e range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Mary\u0026May","offers":[{"title":"Default Title","offer_id":47822572814670,"sku":"MMS01-SC","price":17.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/5057\/0062\/files\/MMS01-SC.png?v=1778671447","url":"https:\/\/skin-nomad.fr\/products\/mary-may-citrus-unshiu-tremella-fuciformis-serum","provider":"Skin-Nomad","version":"1.0","type":"link"}
