How To Use

Application: After cleansing and toning, dispense 3-5 drops of serum into the palm of your hand. Using fingertips, gently press and smooth the serum evenly over your entire face and neck, avoiding the immediate eye area.

Frequency: Can be used once or twice daily. For optimal results, apply in the morning before SPF or in the evening as part of your treatment routine.

Timing: Apply to clean, dry skin before moisturiser. In the morning, always follow with broad-spectrum SPF. Allow the serum to fully absorb before applying subsequent products.

Layering: The lightweight texture layers beautifully under moisturisers, SPF, and makeup. If using other active treatments, speak to our skincare experts for personalized guidance on optimal layering sequence.

Expert Tips: A slight tingling sensation may occur during initial applications, particularly if you're new to Vitamin C or have a compromised skin barrier—this typically subsides as your skin acclimates. For enhanced hydration and a soothing effect, the serum can be mixed with iS Clinical Hydra-Cool Serum in the palm of your hand before application. For best results, use consistently and protect your skin with daily broad-spectrum SPF, as Vitamin C enhances photoprotection when combined with sun protection.

FAQ

Q: How quickly will I see results with iS Clinical Super Serum Advance+?
A: Most users report noticeably brighter, more even-toned skin within 2-4 weeks of consistent use. More significant improvements in skin firmness, fine lines, and wrinkle reduction typically become visible by 8-12 weeks. For optimal results, use the serum consistently and protect your skin with daily broad-spectrum SPF, as Vitamin C works synergistically with sun protection.

Q: Can I use this serum if I have sensitive or acne-prone skin?
A: Absolutely. The iS Clinical Super Serum Advance+ is formulated to be suitable for all skin types, including sensitive and acne-prone complexions. The non-comedogenic formula won't clog pores, whilst the calming ingredients like Centella Asiatica help soothe irritation. The serum also helps fade post-acne marks and reduce inflammation. However, if you're new to Vitamin C or have very sensitive skin, you may experience slight tingling during initial applications—this is normal and typically subsides as your skin acclimates. If persistent irritation occurs, speak to our skincare experts for personalized guidance.

Q: Should I use this serum in the morning or evening?
A: The serum can be used once or twice daily, depending on your skin's needs and tolerance. Many users prefer morning application to benefit from the powerful antioxidant and UV photoprotective properties throughout the day. However, it can also be used in the evening as part of your treatment routine, particularly if you're using prescription retinoids or other active treatments in your morning regimen. Always follow with broad-spectrum SPF when using in the morning.

Q: Can I use this serum alongside other active ingredients like retinol or AHAs?
A: Yes, though it's best to introduce active ingredients gradually and use them at different times of day to minimize potential irritation. The Super Serum Advance+ is typically used in the morning with SPF, whilst stronger exfoliants or retinoids are better suited for evening use. If you experience any irritation, simplify your routine and reintroduce products slowly. Our skincare experts can provide personalized guidance on optimal layering and timing for your specific concerns.

Q: Why should I store this serum in the refrigerator?
A: Vitamin C (L-Ascorbic Acid) is a powerful but inherently unstable ingredient that can oxidize when exposed to light, heat, and air, reducing its effectiveness. Refrigeration helps maintain the stability and potency of the 15% Vitamin C concentration, ensuring you receive maximum benefits from each application. The cool temperature also provides a refreshing, soothing sensation upon application, which many users find particularly pleasant.
