Hyperpigmentation

You may find long after a pimple has healed you are left with a dark-red spot that lasts for weeks, months or even years! This is called hyperpigmentation and skin-lightening creams are sold over-the-counter that claim they will help these spots to fade more quickly. Most of them use a 2% hydroquinone solution, something that will not alter your natural skin tone. However, you should treat the entire skin area with the product and it will lighten a tan. If the 2% solution is not working for you, you can ask your dermatologist about getting a treatment with a stronger concentration. Microdermabrasion and some topical retinoids may also help with hyperpigmentation.

Here are some good non-prescription skin-lightening creams:
