Wulanayvvv review for C the Sun Serum

C The Sun Serum 20% Vitamin C Improves uneven skin tone and dull skin I use C The Sun in the morning before applying moisturizer and before applying sunscreen. The texture of this serum is watery and easily absorbed into the skin. On my oily skin, this serum doesn't make it greasy at all and doesn't make it sticky. Using it for 2 weeks, this serum brightens my face and neck area.
