So I am doing this post for my Grandmother who asked me the other day what she can do about uneven skin tone.

First off:
Skin tone comes from melanin, a compound that produces the pigmentation in your skin cells. Melanin reacts to ultraviolet light, such as that from the sun or from tanning beds. The more light that you are exposed to, the darker your skin’s pigmentation becomes. However, some areas of your body may contain more melanin than others, and some parts of your body may receive less exposure to light. When this happens, you may experience an appearance of uneven skin tone.


What you can do to improve your skin:
Exfoliate!
The best way to improve skin tone is to exfoliate regularly. Exfoliation is the removal of dead skin cells from the outer layer of the skin. The top, outer layer of skin is usually the sole cause of discoloration because of its direct contact with sunlight. Once you remove this top layer, the skin underneath should be even and normal.


Chemicals!
Chemical exfoliation uses enzymes, such as fruit acids, beta hydroxyl lotions or chemical peels to strip away your top layer of dead skin. They clean your pores from the inside out and fix uneven skin tone, but it is important to start this process slowly. Begin with occasional use of a very mild product. Look for a product that contains alpha hydroxy acids (AHA). Common types of AHAs include glycolic acid (found in sugar), malic acid (from apples) and tartaric acid (in grapes). 


Reduce Cellulite!
Another cause of uneven skin tone is cellulite. No matter what you may hear on late-night infomercials, there is no way to truly get rid of cellulite. But there are things you can do to improve your overall skin tone and, thus, minimize its appearance.
The key to reducing cellulite, like so many other things in life, is nutrition and exercise. Eating a healthy, balanced diet that is high in protein and vitamin C will keep your body active and your skin radiant and glowing. And what is the top mainstay of a skin-friendly diet? Water! Drinking lots of water helps expand your muscles, which minimizes the cellulite’s puffiness.
Keeping your muscles toned through exercise is one of the best ways to fight cellulite and improve skin tone. Running, squats and other leg exercises are especially important for women who have cellulite around their buttocks and thighs. If you can reduce your overall body fat and tighten your skin, your cellulite will be much harder to see.
For cellulite quick-fixes you can also indulge in mud baths, steam baths, or massage therapy. 


Also try a moisturizer with SPF to help block sun damage. 
Witch hazel can help reduce the appearance of uneven skin tone.
Stay away from benzoyl peroxide, this can cause unevenness in skin tone. Many acne medications contain this.
