    How do you guys stay in business? You are a comedy act. You never give ANY EVIDENCE that anything works. What you think is no more relevant than the snake oil salesmen of time immemorial. I spend hundreds a month on supplements and skincare. At 73, I look younger than my age BUT have no idea why. I exercise like a 35 year old and have a great, clean diet. I am sure that is the reason I am deteriorating less. Of all the sites I have viewed, yours is the least professional and least helpful.

    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.
