How to Use Both Together:
First, take Whitening Serum. Use in the morning on bare face (before applying anything else), take 3/4 drops and apply directly on face. Massage gently until the serum is absorbed.
After Whitening Serum is absorbed, take 3/4 drops of Vitamin C & E Serum and apply directly on face. Massage gently until the serum is soaked into the skin.
Do the same at night. After cleansing your face, apply Whitening Serum first and then Vitamin C & E Serum for an all-night repair rejuvenation.
