Face scrubs are very good as they slough away dead cells and give a glow to the dead and lifeless looking complexion. Take care not to use a scrub when you have angry looking pimples on the face. A scrub can at times aggravate the situation.

To make it easier use the scrub under the category of your skin type. The same with face packs. Use only what is suitable to your skin. Though the homemade packs are very gentle and will not cause any harm, do keep in mind, any allergies you may have.

Also, there are packs made for specific area such as "nose packs."
