To use this concealer, first prep your skin with a moisturizer. Then, squeeze a small amount of the concealer onto your finger or a concealer brush. Dab it gently on the blemishes or areas you want to cover, and blend it well. Make sure to blend it evenly to avoid any harsh lines. When it comes to storage, keep it in a cool and dry place. Avoid exposing it to direct sunlight or high temperatures, as this may affect its quality. If you have sensitive skin, it's a good idea to do a patch test on your wrist before using it all over your face.
