K5® Lipogel allergen-free formulation is a highly effective gel with a fast whitening action on highly pigmented brown skin spots due to excessive sun exposure, age, oral contraceptives, use of photosensitizing products, freckles and pigmentation around scars caused by acne or surgical intervention. K5® Lipogel normalizes skin pigmentation. K5 ® Lipogel, with Pidobenzone 4% (Italy Patented Formula), acts by inhibiting Tyrosinase, the enzyme involved in the production of melanin, with bleaching action. At the same time, it has a protective action due to the incorporation of a solar filter. K5® Lipogel has been clinically tested by dermatologists for efficacy and safety. It is highly recommended around the world. To obtain satisfactory results K5® Lipogel should be applied for two to three consecutive months, one to two times a day.
