    • Studies show that the potential side effects and risks of hydrogen peroxide outweigh the benefits. If you’re trying to lighten dark spots, use azelaic acid, glycolic acid, kojic acid, retinoids, or vitamin C instead. [3]

  1. According to skincare professional Alicia Ramos, “Retinol peels away the top layers of your skin, reducing the appearance of wrinkles, sun spots, and other pigmentation problems.” Retinol is available over-the-counter in gel , serum , or cream form. If you’re using it for the first time, cleanse your skin and let it dry completely, apply a thin layer of product, then follow up with a non-comedogenic moisturizer. [5]
    • Since retinol increases your skin’s sensitivity to the sun, only apply it at night, and be sure to wear sunscreen and protective clothing during the day. [6]
    • Common side effects of retinol include dryness, redness, irritation, itching, burning, or peeling or flaking of the skin. If you develop a painful or severe reaction, stop using it and contact your healthcare provider immediately. [7]
    • If you’ve never used retinol before, start with a pea-sized amount every other day and then use it daily after 3-4 weeks. Slowly incorporating the ingredient into your routine reduces the risk of side effects. [8] It may take several weeks to see an improvement in your skin. [9]
  2. Glycolic acid is an alpha-hydroxy acid that works to smooth out the skin’s surface, refine pores, and improve discoloration, fine lines, and wrinkles. The acid can irritate your skin if you’ve never used it before, so start by applying it once or twice a week at night. [10]
    • Possible side effects of glycolic acid include reddening, stinging, or burning of the skin, as well as a pulling sensation. [11]
    • Glycolic acid is a common exfoliant in creams , serums , and masks . Look for a product with a concentration of 10% or less to minimize irritation, and follow the instructions of your specific product.
  3. Azelaic acid is a dicarboxylic acid that can reduce pigmentation and fade dark spots. [12] It’s a good option for people with sensitive skin or melasma, and it comes in cream, foam, and gel form. [13]
    • Apply a thin layer of cream to the affected area twice a day for at least 4 weeks.
    • Potential side effects of azelaic acid include redness, scaling, itching, and burning of the skin. [14]
  4. According to licensed esthetician Kimberly Tan, “kojic acid is a powerhouse ingredient to brighten the skin.” Kojic acid prevents your skin from forming tyrosinase (an enzyme that helps create melanin), and studies show that it can reduce skin discoloration due to acne or sun damage. [15]
    • Look for serums , creams , or treatments that contain kojic acid.
    • Kojic acid is usually well tolerated, but potential side effects include allergy or irritation. [16]
  5. “Vitamin C serums work nicely to remove dark spots on the face,” according to board-certified dermatologist Aanand Geria, MD. When used topically, it can help even out skin tone by fading sun spots and reducing hyperpigmentation, but it usually takes about 3 months to see results. [17]
    • Choose a concentration that’s between 10-20%, and make sure it’s in a dark or tinted bottle.
    • Apply vitamin C serum after cleansing your face (and after applying toner, if applicable). You can use it in the morning or at night, but it works in synergy with sunscreen.
  6. Hydroquinone is one of the most effective bleaching agents because it limits the skin’s production of melanin (the pigment responsible for skin color). While it is FDA-approved as a skin lightener, hydroquinone cream is only available by prescription. Talk to a doctor to see if it’s a good option for you, and follow the directions of your specific prescription. [18]
    • Make sure to wash your hands before and after using hydroquinone, and avoid excessive exposure to sunlight. Wear sunscreen (SPF 15 or higher) and protective clothing during the day. [19]
    • The most common side effects of hydroquinone cream include mild itching, stinging, or redness of the skin. Serious side effects include rashes, facial swelling, and permanent skin discoloration. [20]

      Tips

      • Instead of using hydrogen peroxide to treat wounds, wash minor cuts and scrapes with soap and water, pat the area dry, apply an antibacterial ointment , then cover it with a wrap or bandage. Change the covering at least once a day or whenever it gets wet or dirty. [26]
      • If you’re looking to treat acne, talk to a dermatologist to determine what type of pimples you have. Benzoyl peroxide, adapalene, and salicylic acid are popular ingredients to clear mild-to-moderate acne. [27]
      • Keep your hydrogen peroxide in a cool and dark area, away from children or pets. Once it loses its bubbles, it’s no longer effective—dump it down the sink and buy a new bottle. [28]

      • If you get hydrogen peroxide on your skin, rinse the affected area thoroughly with water. If it gets into your eyes, rinse for 15-20 minutes under running water. [29]
      • If you accidentally ingest or inhale a higher concentration of hydrogen peroxide (10% or more), seek medical care immediately. It can cause life-threatening conditions, such as a gas embolism, an accumulation of fluid in the lungs, unconsciousness, and respiratory arrest. [30]
