What Is Hydroquinone?

Hydroquinone is a skin-lightening agent that bleaches the skin. It’s commonly used to treat hyperpigmentation, melasma, age spots, acne scars, and other dark pigments on the skin.

How Does Hydroquinone Work?

Hydroquinone reduces the number of melanocytes under the skin by impeding the production of tyrosinase, an enzyme that creates melanin. Fewer melanocytes mean that the body will produce less melanin, thereby lightening the skin.

Common Forms of Hydroquinone

You can buy hydroquinone as a gel, cream, or lotion. These skin-lightening formulations mix hydroquinone with other ingredients, such as retinol or tretinoin. Hydroquinone is available over-the-counter in drug stores and beauty stores at two percent strength. A stronger hydroquinone emulsion, or a solution that is just hydroquinone, is only available with a prescription from a dermatologist.

6 Tips for Using Hydroquinone

You can use hydroquinone to treat dark spots and create an even skin tone, but follow these tips to add the product to your skincare routine safely:

  1. 1. Use as a spot treatment. Apply hydroquinone in a thin layer to affected areas of the face. Do not apply it to other areas of the face; otherwise, it will bleach that skin.
  2. 2. Avoid peroxide products. Avoid using hydroquinone with peroxide products such as benzoyl peroxide or hydrogen peroxide, which can cause discoloration.
  3. 3. Avoid alpha hydroxy acids. The combination of hydroquinone and alpha hydroxy acids (AHAs) can irritate your skin.
  4. 4. Apply sunscreen. When using hydroquinone, use a strong SPF sunscreen during the day since sun exposure can cause further skin damage, including hyperpigmentation.
  5. 5. Consider side effects. Hydroquinone is generally safe for all skin types, but there may be side effects, especially for users with sensitive skin. Possible side effects include skin irritation, redness, dryness, and contact dermatitis when first using hydroquinone. If these adverse effects persist, discontinue using hydroquinone. Avoid hydroquinone if you are pregnant or breastfeeding.
  6. 6. Stop application after five months. If your skin lightens, stop using hydroquinone regularly and only use it if the dark spots reappear. Wait two or three months to use it in the same areas. Prolonged regular use of hydroquinone may lead to exogenous ochronosis, which can cause blue-black pigmentation and papules, red bumps on the skin.

How to Use Hydroquinone

Follow these steps to add hydroquinone to your skincare routine:

  1. 1. Test on your skin. Before beginning treatment, test hydroquinone on a small area of your skin and wait 24 hours to observe any possible side effects.
  2. 2. Wash your face with a cleanser. Cleanse your face before applying hydroquinone.
  3. 3. Apply hydroquinone twice a day. You can apply hydroquinone in the morning and evening. Let it sink into the skin before applying other products, such as moisturizer, and wash your hands after using hydroquinone, so it does not bleach your fingers.
  4. 4. Assess your skin. The treated areas should start to appear lighter in four weeks. They do not lighten after three months, discontinue usage of hydroquinone and get medical advice from your dermatologist. You may need a stronger concentration of hydroquinone or if an alternative treatment, such as vitamin C.

Before Starting a New Skincare Regimen
