This formula combines two of the most powerful brightening agents in skincare: pure Vitamin C and Alpha Arbutin, both solubilized in a completely water-free formula for ideal stability. Vitamin C is an effective antioxidant that brightens the skin tone and reduces signs of aging. Alpha Arbutin is a highly-purified biosynthetic active ingredient that reduces the look of dark spots and uneven skin tone.
I haven't used it long enough to see any marked difference- vitamin c takes at least 3 weeks, but I'm happy it hasn't broken me our or presented any other adverse reaction. I will be back for a full review after 4 weeks.
