  1. vitamin c gives me a bad reaction every single time. Im highly sensitive to this ingredient for some reason.

    Can someone give me some recommendations if they have same issue as me?

    The last I tired was beauty of Joseon centella vita-c and the my whole face was on fire, red swollen and inflamed, it was so bad.

  2. Where are the discounts you said you had below?

  3. My Vitamins C serum is TruSkin & it is fabulous! My skin hasn’t looked better!
