I’m a teacher. My financial situation doesn't exactly accommodate Ling skincare. But I budget for these because I really, truly love them. This serum is incredible. I have extremely sensitive skin and have been hospitalized several times due to skin allergies. I have tried six Ling products so far and have never had a negative reaction. Which isn’t normal for me. I’m allergic to laundry detergent. I swear I’m not being paid or anything for this review, I just really, really love the products. They work. They’re worth the price. I’ll never go back.
