How it works

Hydroquinone inhibits tyrosinase, an enzyme involved in melanin production, which helps reduce the formation of excess pigment in treated areas. Regular application to pigmented spots can gradually lighten discoloration and improve overall tone.

Who it’s for

• People with hyperpigmentation, sun spots, melasma or post-acne marks
• Those seeking a targeted, prescription-strength-style brightening option in an over-the-counter concentration
• Not recommended for use on broken or inflamed skin

Directions for use

1. Cleanse and pat skin dry.
2. Apply a thin layer to affected areas once daily in the evening (or as directed by a dermatologist).
3. Follow with moisturizer if needed.
4. Use broad-spectrum sunscreen (SPF 30+) every morning while using hydroquinone and for 4 weeks after discontinuation to prevent rebound pigmentation.
5. Patch test prior to first use.

Note: Many dermatologists recommend limiting continuous hydroquinone use to a few months and taking periodic breaks; consult your healthcare professional for a regimen tailored to you.

Precautions & warnings

• Perform a patch test before first use. Discontinue if irritation, severe redness or swelling occurs.
• Avoid use during pregnancy or breastfeeding unless advised by a physician.
• Avoid mixing with strong exfoliants/retinoids or other potentially irritating actives without professional guidance — combine carefully or alternate nights.
• Use sun protection daily; sun exposure can worsen pigmentation and reduce treatment effectiveness.
• For external use only. Keep out of reach of children. Avoid contact with eyes and mucous membranes.
• Prolonged, unsupervised use of hydroquinone can increase the risk of unwanted effects; consult a dermatologist for long-term strategies.

Typical timeline

Many users begin to see improvement in 4–8 weeks, with more noticeable changes over 2–3 months. Results vary depending on the cause and depth of pigmentation and adherence to sun protection.

Storage & packaging

• Store in a cool, dry place away from direct sunlight.
• Keep container tightly closed when not in use.
• 30 ml bottle — compact for home use and travel.

Frequently asked questions

• Will it bleach normal skin? When used as directed, hydroquinone targets hyperpigmented areas and should not permanently lighten normal surrounding skin. Avoid overapplication.
• Can I use it every day? Most people use it once nightly; frequency should be adjusted based on tolerance and dermatologist advice.
• Can I combine with vitamin C or retinoids? Combining can increase irritation — consult a dermatologist or introduce actives gradually and monitor skin response.

For best and safest results, consider consulting a dermatologist before beginning hydroquinone treatment, especially for melasma, deeper pigmentation concerns, pregnancy, or prolonged use.
