Kaixerol usually has no effect on spot removal, and generally cannot be used to remove spots. The formation of spots mainly depends on the active or proliferation of epidermal melanocytes, and the increase of epidermal melanosomes or the formation of pigmentophilic cells in the dermis will make the skin darker. To remove spots, topical drugs need to inhibit tyrosinase activity, thus reducing melanocyte synthesis, promoting epidermal metabolism and inhibiting dermal inflammation. Glycerin and magnesium sulfate should not be applied to the face, and glycerin has moisturizing and hydrating effects, but it cannot remove spots. Although glycerin has moisturizing effect, it can not remove spots. Moreover, the concentration of glycerin in Keserol is too high, so it can be used directly for skin care, but it may cause water loss in the skin, resulting in dryness and burning of the skin, so try not to apply it on the face. If you need to remove spots, it is recommended that you choose the appropriate spot reduction products or take medical aesthetic methods under the guidance of a doctor. Products for spot reduction usually include tyrosinase inhibitors such as arbutin, vitamin C and its derivatives, products for accelerating melanin metabolism such as niacinamide, antioxidant products such as vitamin E and its derivatives, products for accelerating epidermal cell metabolism such as vitamin A acid and fruit acid. Medical aesthetic modalities such as photorejuvenation and laser treatment are available. If allergies or other uncomfortable symptoms occur during the treatment period, you should seek medical attention in time. Avoid sun exposure and a light diet, avoiding oily and spicy stimulating foods.
