How is this different from over-the-counter hydroquinone?

This pharmaceutical-grade 2% hydroquinone is compounded fresh in a stabilized base that prevents oxidation and maintains potency. OTC versions are typically 1% and often lose effectiveness due to improper storage and formulation.

Can I use this with retinol or vitamin C?

Use hydroquinone in the evening and vitamin C in the morning. Avoid using with retinol initially - your RELUXE provider will guide you on when to introduce retinoids based on your skin's tolerance.

Why do I need to take breaks from hydroquinone?

Continuous use beyond 12 weeks can lead to ochronosis (darkening) in rare cases. The 4-week break allows your skin to reset while maintaining your results, then you can safely resume treatment.

Will this work for all types of dark spots?

Hydroquinone is most effective for melasma, sun spots, and post-inflammatory hyperpigmentation. Deep dermal pigmentation may require combination treatments like IPL or chemical peels for optimal results.

About P Serum + Hydroquinone (HQ)

P Serum + Hydroquinone delivers 2% pharmaceutical-grade hydroquinone in a customizable base formulated specifically for your skin's needs. This prescription-strength depigmenting agent works by inhibiting tyrosinase, the key enzyme responsible for melanin production, making it the gold standard for treating stubborn melasma, post-inflammatory hyperpigmentation, and age spots that don't respond to other treatments. Universkin's personalized approach means your P Serum HQ is compounded fresh with complementary actives chosen during your SkinIQ analysis at RELUXE. The lightweight serum absorbs quickly without irritation when properly introduced, delivering targeted results where you need them most. Clinical studies show visible improvement in pigmentation density within 6-8 weeks of consistent use. This 30ml treatment serum is ideal for patients who have tried vitamin C and kojic acid without seeing significant results, or those dealing with hormonal melasma, sun damage, or post-acne marks that require prescription-strength intervention.

How to Use

Apply 2-3 drops to clean, dry skin in the evening only. Start with every other night for the first week, then gradually increase to nightly as tolerated. Use only on affected areas - avoid eye area and lips. Always follow with a moisturizer and use broad-spectrum SPF 30+ during the day. Discontinue use after 12 weeks and take a 4-week break before resuming.

Pro Tip from Our Clinicians

Hydroquinone works synergistically with chemical peels - patients often see accelerated results when combining P Serum HQ with our VI Peel treatments. Start the serum 2 weeks after your peel for optimal tolerance and enhanced pigment correction.
