What Is Hydroquinone?

Hydroquinone is a topical skin-lightening agent that works by decreasing the formation of melanin (the pigment responsible for dark spots). Dermatologists often recommend hydroquinone creams for conditions such as:

• Melasma

• Post-acne marks

• Age spots

• Sun damage

What are the benefits of hydroquinone?

Hydroquinone is particularly effective for the treatment of postinflammatory hyperpigmentation which is unlikely to recur provided the underlying inflammatory dermatosis is also controlled.

In melasma, 70% of sufferers notice clearance or reduction in pigmentation with twice daily hydroquinone used for three months. This improvement can be maintained in 50% of individuals with twice weekly application.

Mechanism of action of hydroquinone

Hydroquinone lightens epidermal, but not dermal, pigmentation by reducing the production of new melanin:

• Reversible inhibition of tyrosinase, an enzyme involved in converting L3,4-diphenylalanine to the skin pigment melanin
• Selective damage to melanocytes and melanosomes.

How to Use Hydroquinone Correctly

1. Do a Patch Test

Before applying hydroquinone on your entire face, test it on a small area of skin to check for irritation or allergic reactions.

2. Cleanse Your Skin

Wash your face with a mild cleanser and pat dry before applying the cream.

3. Apply a Thin Layer

• Use a pea-sized amount only on the dark spots, not the whole face.

• Apply once daily at night (or as recommended by your dermatologist).

4. Always Use Sunscreen

Hydroquinone makes your skin more sensitive to the sun. Apply a broad-spectrum SPF 30+ sunscreen every morning.

5. Be Consistent but Cautious

• Results may take 4–8 weeks.

• Avoid using hydroquinone continuously for more than 3–4 months without medical advice.

Important Precautions When Using Hydroquinone

• Do not use on broken or irritated skin.

• Avoid combining with harsh exfoliants unless prescribed.

• Pregnant or breastfeeding women should consult a doctor before use.

• Store in a cool, dry place away from sunlight.

Potential Side Effects

While hydroquinone is generally safe, some users may experience:

• Mild irritation or redness

• Temporary dryness

• Rarely, ochronosis (bluish-black discoloration with long-term use)

If you notice severe side effects, stop using and consult your dermatologist immediately.

• Melasma
• Postinflammatory hyperpigmentation such as subsequent to acne
• Freckles and lentigines
