Hiruval 35 Evanescent Cream The cream is effective for bruising, staining, and spotting of the skin, oxyhemoglobin (black dots) and hyperpigmentation, and other surface vein discoloration, including after cosmetic surgery and sclerotherapy. Field testing has shown that unsightly blemishes are reduced and in many cases the discoloration completely disappears. HIRUVAL 35 is made with all natural ingredients. The principal ingredient is hirudin, a standardized extract of leech (hirudo medicinalis). Its thrombolytic and anticoagulant activity dissolves coagulated, oxidized blood and leaves the skin uniform in color. Hiruval 35 is not a bleaching agent. Application: Hiruval 35 Cream is highly evanescent. Apply a quantity about the size of a small pea and rub gently until the cream has been completely absorbed. Repeat the application 2 - 3 times daily. The cream should be applied lightly with the fingertips. Expect satisfactory results after 2 - 4 weeks of application. Do not apply to broken skin. Discontinue if signs of irritation occur. Results may vary by individual. The ingredients of Hiruval 35 cream are GRAS (Generally Recognized As Safe). The cream is stabilized with methyl and propyl paraben, very lightly perfumed with oil of lavender, and is produced under GMP (Good Manufacturing Practice).
