Using this Private Label Skin - Brightening Serum is easy. First, make sure your skin is clean. Then, take a small amount of the serum and gently massage it over your face and throat. After that, use your regular moisturizer. If you want a more intensive treatment, apply a thin layer of the serum all over your face, wait for it to dry, and then put on a mask. There aren't any specific special precautions for this product, but as with any skin - care item, if you have sensitive skin, you may want to do a patch test first. To keep the serum effective, store it in a cool, dry place away from direct sunlight. This will help maintain the quality of the ingredients and ensure the serum works well for you over time.
