Does kojic acid work for brown spots?

Dear Dr. Irwin, I have heard a lot about kojic acid lately. Is it an effective way of lightening sun-induced pigmentation on very fair skin, and is the amount of active ingredient in over-the-counter products likely to be worth the money? Thank you.

Generally, results are unimpressive with it.  Unless there’s a new preparation that I’ve haven’t seen, I’d vote no.  Pigment strategies can be found in our Melasma in Depth Section.    Dr. I

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes!
