Product Description

Symwhite is a patented natural whitening ingredient. It is mainly used in skin care products because it reduces the appearance of dark spots, pigmentation and uneven skin tone. Symwhite works by inhibiting the activity of tyrosinase, an enzyme involved in the production of melanin, the pigment responsible for skin color. By inhibiting tyrosinase, Symwhite helps reduce the production of melanin, resulting in a brighter, more even skin tone. It is considered a safe and effective alternative to whitening ingredients such as hydroquinone, which may have potential side effects. In addition to its skin-lightening properties, Symwhite also has antioxidant and anti-inflammatory effects. It helps protect the skin from oxidative stress caused by free radicals and environmental factors, and it can help calm and soothe irritated or inflamed skin. Overall, Symwhite is a versatile ingredient that can be used in various skincare products, including serums, creams, and lotions, to address issues related to skin discoloration, dark spots, and uneven skin tone.
