You need to make a face mask from an egg white. Spread a thin layer and allow it to dry a little. Then continue with 2 more thin layers, allowing each one of them to dry before you apply the next one. Leave the mask on your face for 10-15 minutes and then gently scrub the mask of your face with warm water.
It is true that the smell is not the most pleasant one, but the result makes it worth the sacrifice.
