How To Use

Application: Apply 3-4 drops to the palm of your hand. Using fingertips, dab and smooth evenly over cleansed face and neck, or areas affected by pigmentation irregularities. This active product may produce a slight tingling sensation, which is normal and typically subsides within two minutes.

Frequency: For primary hyperpigmentation concerns, use both morning and evening. For minor concerns, use once daily in either morning or evening routine. Consistency is essential for optimal results.

Timing: Can be used morning and/or evening as part of your skincare regime. Many users prefer evening application to maximise overnight renewal benefits.

Layering: Allow the serum to fully absorb before applying moisturiser (approximately 2-3 minutes). Always follow with broad-spectrum SPF during daytime use. Pairs beautifully with iS Clinical Brightening Complex for comprehensive 24-hour brightening support.

Expert Tips: Hyperpigmentation treatment requires patience and consistency. For best results, incorporate this serum into a complete iS Clinical regime including cleansing, hydration, and diligent SPF application.

FAQ

Q: How quickly will I see results from the Brightening Serum?
A: Clinical studies demonstrate a 75% reduction in hyperpigmentation intensity after three months of consistent use, with 84% of participants noting overall brightening improvements. Many users report visible improvements within 2-4 weeks, though individual results vary depending on the severity and type of pigmentation. Consistency is key—hyperpigmentation is challenging to treat and requires patience alongside diligent SPF use.

Q: Can I use this serum if I have sensitive skin?
A: Yes, the formulation is designed to provide controlled exfoliation without inflammatory effects. However, we recommend introducing the product gradually—start with once daily application and monitor your skin's response. The tingling sensation is normal and should subside within two minutes. If persistent irritation occurs, reduce frequency or speak to our skincare experts for personalised guidance.

Q: Is it safe to use this serum year-round, including summer?
A: Absolutely. Unlike hydroquinone-based products, iS Clinical Brightening Serum can be safely used throughout the year without photosensitivity concerns. The botanically-based, antioxidant-rich formula actually provides protective benefits. However, diligent SPF application (reapplied every 2 hours during sun exposure) is essential to prevent further pigmentation and protect newly revealed skin.

Q: Can I use this alongside other iS Clinical products?
A: Yes, this serum works beautifully as part of a complete iS Clinical regime. For comprehensive 24-hour brightening support, pair with iS Clinical Brightening Complex (use in morning, Brightening Serum in evening). Always cleanse first, apply the serum, allow absorption, then follow with moisturiser and SPF. For personalised layering recommendations based on your specific concerns, speak to our experts.

Q: What's the difference between Brightening Serum and Brightening Complex?
A: Whilst both target hyperpigmentation, Brightening Serum is a lightweight treatment serum with more intensive exfoliating properties, ideal for evening use or as a targeted booster. Brightening Complex is a richer moisturising treatment typically used in the morning. Many clients achieve optimal results using both products as part of a comprehensive brightening regime. Our experts can help determine the best approach for your specific needs.
