Is Hydroquinone Safe During Pregnancy? #

Hydroquinone is a potent pigment-lightening ingredient. Because it can have higher systemic absorption than many other topicals, many clinicians recommend avoiding it during pregnancy. In our ingredient classification, hydroquinone is medium risk, which means it’s not a default pregnancy-safe active and should only be used if your clinician specifically recommends it. Melasma often responds well to sun protection, azelaic acid, and steady routines.

What to avoid #

• Leave-on hydroquinone creams and serums.
• DIY or unlabelled "lightening" products.
• Combining hydroquinone with strong peels or retinoids.

Safer melasma-friendly alternatives #

• Azelaic acid (15-20%): anti-inflammatory and pigment-friendly; see NHS: https://www.nhs.uk/medicines/azelaic-acid/
• Niacinamide (4-10%): supports tone and barrier with low irritation.
• Mineral sunscreen (SPF 30/50): daily, generous application; tinted mineral SPF for cosmetic coverage.
• Gentle exfoliation: mild lactic or mandelic cleansers if clinician-approved; skip strong peels.
• Example routine picks from our product data (brand • name • safety score):
  • Mesoestetic • Mesoprotech Moisturising Sun Protection SPF 50+ • 100 (daily protection).
  • Boots • Baby Petroleum Jelly • 100 (simple occlusive at night).
  • Bambu Earth • Rosewater Cleanser • 100 (hydrating cleanse).
  • Doctor Rogers RESTORE® • Doctor Rogers RESTORE® Restore Healing Balm • 100 (barrier support on dry spots).

Application tips #

• Use sunscreen every morning; reapply if outdoors.
• Avoid heat triggers when you can (sauna, very hot showers on the face).
• Patch test new products; add one at a time.
• Consider makeup with iron oxides (tinted SPF, CC creams) for immediate camouflage of melasma.
• Keep a simple routine: gentle cleanse → azelaic/niacinamide → moisturiser → SPF.

Simple melasma routine (example) #

• AM: Gentle cleanser → Niacinamide → Moisturiser → Tinted mineral SPF 50.
• PM: Gentle cleanser → Azelaic acid → Moisturiser. Skip azelaic on nights your skin feels tight.
• Weekly (if clinician approves): Mild lactic cleanser 1-2x/week instead of a peel.

When to see a clinician #

• Rapidly spreading pigmentation, burning, or itching.
• Considering in-office treatments; seek pregnancy-safe options and disclose everything you use.
• If you used hydroquinone before knowing you were pregnant: stop and discuss with your clinician; they may reassure you based on typical topical exposure, but personalised advice matters.
