Using wonderful moisturizer from korea sold in us told if i buy it online or in asia it might have bleaching solution/i'm a blonde so is that harmful?

Maybe: There may be harmful ingredients such as heavy metals in Asian products which.Are not allowed to be used in us. Products for bleaching and psoriasis had medications in high concentrations , which were later banned, be careful.

Be careful: I agree. Unregulated products may contain mercury and other potentially harmful ingredients, not worth the health risk. There are so many wonderful options here in the U.S. I would recommend meeting with your dermatologist and discussing your skin care needs to obtain high quality, results proven, safe products.
