Summary of Hydroquinone vs. Tretinoin
Summary for Depigmenting Agent
Prescription only
Hydroquinone cream is used to bleach dark spots or patches on your skin (hyperpigmentation, or skin discoloration) from certain skin conditions, such as freckles, melasma, and aging. Hydroquinone cream is applied to the skin, typically twice daily. It's important to protect yourself from the sun while you use this skin-lightening medication because it makes your skin more sensitive to the sun. The most common side effects of hydroquinone cream include redness and stinging on the skin. Currently, hydroquinone cream is available by prescription only. The FDA no longer approves the sale of over-the-counter (OTC) hydroquinone cream.
