A member asked:
The skin on my knees is so dark these days, it's really annoying me and i am ashamed of it. is there any way to make them look lighter?

Sun block is key: Skin lighteners such as kojic acid, hydroquinone, and plant extracts should only be used if proper sun protection is used. Over the counter products are safe and generally contain 2% kojic acid which limit their effectiveness. They work by blocking the production of melanin which is the natural pigment in the skin cells. Always check with a dermatologist to make sure there are no contraindications.
