You should use soap that depends on your skin type. Otherwise, you’ll have another problem.

• Oily Skin. Choose that has a milder formula or gentle ingredients. If you’re on to exfoliation, find soaps with oatmeal, sea salt, brown sugar or peach pits.
• Dry Skin. A soap with moisturizing agents is the right one for you like glycerin soaps.
• Sensitive Skin. Find soaps which are perfume-free, also pH-balanced or hypo-allergenic.
• Combination Skin. This is a combination of dry and oily skin. You may use soap with glycerin.
• Normal Skin. This is not too oily nor too dry. There are available soaps which are for normal skin. Avoid those which are for dry or oily skin.

There are also some soaps specially formulated like herbal soaps or defense soap which is mostly for athletes.
