How To Use

Application: Apply 3-4 drops to the palm of your hand or place 2-3 drops on the back of your hand. Using fingertips, dab and smooth evenly over freshly cleansed face and neck, avoiding the immediate eye area. The serum may be applied to the entire face or used as a targeted spot treatment for specific concerns.

Frequency: For optimal results, use every other day or 2-3 times per week, depending on your skin's tolerance and specific concerns. Those with sensitive skin should begin with twice-weekly application and gradually increase frequency as tolerance develops.

Timing: Preferably apply in the evening as part of your nighttime skincare routine. The serum's active exfoliating properties work synergistically with the skin's natural overnight repair processes. May also be used in the morning if desired, though evening application is recommended for best results.

Layering: Apply after cleansing and toning, before moisturiser. Allow the serum to fully absorb for 2-3 minutes before applying subsequent products. The lightweight formula layers beautifully with other iS Clinical treatments and moisturisers without pilling or interference.

Expert Tips: A slight tingling sensation upon application is normal and indicates the active botanical extracts are working. This sensation should subside within a few minutes. For those new to active serums, our experts recommend starting with twice-weekly application to allow your skin to acclimate to the exfoliating properties before increasing frequency.

FAQ

Q: How quickly can I expect to see results with Active Serum?
A: Many users report visible improvements within the first few applications, with noticeable changes in skin clarity, texture, and radiance typically observed within 3-5 uses. For concerns such as fine lines, hyperpigmentation, and acne, optimal results develop over 4-8 weeks of consistent use. The serum provides both immediate benefits (enhanced glow, smoother texture) and cumulative long-term improvements with continued application.

Q: Can I use Active Serum if I have sensitive skin?
A: Yes, whilst Active Serum contains effective exfoliating acids, the botanical sources make it gentler than synthetic alternatives. However, those with sensitive skin should start with application twice weekly, gradually increasing frequency as tolerance develops. The characteristic tingling sensation is normal, but if you experience excessive redness or irritation, reduce application frequency. Speak to our skincare experts for personalized guidance on incorporating Active Serum into a sensitive skin routine.

Q: Why does the serum tingle when I apply it?
A: The cool, tingling sensation is a normal response indicating that the active botanical extracts—particularly the natural acids from Sugar Cane, Bilberry, and Willow Bark—are penetrating your skin and working effectively. This sensation should subside within 2-3 minutes. It's not a sign of irritation but rather evidence of the formula's potency and deep skin penetration. If the sensation persists beyond a few minutes or becomes uncomfortable, discontinue use and consult our skincare specialists.

Q: Can I use Active Serum with other iS Clinical products?
A: Absolutely. Active Serum works beautifully as part of a comprehensive iS Clinical regimen. It's particularly effective when followed by hydrating serums such as Hydra-Cool Serum or nourishing treatments like Poly-Vitamin Serum. For anti-aging concerns, it pairs excellently with Youth Serum or Pro-Heal Serum Advance+. Our experts can help design a customized routine that maximizes the benefits of Active Serum within your complete skincare protocol.

Q: Should I use Active Serum in the morning or evening?
A: Evening application is strongly recommended as the serum's exfoliating properties can increase sun sensitivity. Using Active Serum at night allows the active ingredients to work synergistically with your skin's natural overnight repair processes. If you prefer morning application, ensure you follow with a broad-spectrum SPF 30 or higher and limit sun exposure throughout the day.

Q: Can Active Serum help with both acne and aging concerns?
A: Yes, this is one of Active Serum's standout features. The multi-tasking formula addresses multiple skin concerns simultaneously through its unique combination of botanical acids. Salicylic Acid from Willow Bark deep-cleanses pores to combat acne, whilst Glycolic and Lactic Acids from Sugar Cane and Bilberry promote cellular turnover to reduce fine lines and wrinkles. This makes it ideal for those experiencing both breakouts and early signs of aging—a common concern for many adults.
