The solid particles seen are completely normal and expected in this formula. Most importantly, your Makeup Finishing Spray is 100% safe. The particles seen are a combination of two ingredients that provide the cooling and matte properties respectively, both of which are important for the makeup setting properties of your spray. The super-fine particles will never fully dissolve but rather be dispersed throughout the product. This is why there are very specific instructions for "Shake Well Before Use' on yours. Shaking/agitating the product allows these powders to disperse throughout the liquid finishing spray for even application on the skin. We know the off-white color can look concerning, but we promise … your Skindinavia Makeup Finishing Spray is safe and ready to work its magic!
