iS CLINICAL Active Serum facial treatment, 1 fl oz — fast-acting smoothing & tone-correcting serum

iS CLINICAL Active Serum is a fast-acting, multi-tasking botanical face serum formulated to smooth skin, help even tone, and support clearer-looking skin for all ages and types.

Active Serum from iS CLINICAL is the brand's bestseller and a targeted treatment serum designed to produce noticeable improvements quickly while continuing to support skin texture and tone over time. Lightweight and concentrated, the formula combines botanical extracts and clinically guided actives to deliver a visibly smoother surface and a hydrated finish. Many users report a cooling or tingling sensation on application — a sign of the formula's activity — followed by a dewy, softened feel.

How quickly will I see results after starting Active Serum?

Results vary by individual, but iS CLINICAL Active Serum is designed for rapid visible improvement as well as long-term benefits. Some users notice changes within a few days, especially in texture and radiance, while continued use enhances tone and minimizes the look of fine lines.

• Often noticeable smoothing within days of use.
• Progressively improves tone and fine lines over weeks.
• Recommended daily application for sustained results.

Can this serum be used on acne-prone or sensitive skin?

Active Serum is formulated to be suitable for a wide range of skin types, including blemish-prone skin. It contains botanical and targeted ingredients intended to help refine skin texture and support clearer-looking skin, though individual sensitivity varies and a brief tingling may occur on application.

• Suitable for oily and combination complexions.
• Works for mature and younger skin seeking improved clarity.
• Patch-test first if you have highly reactive skin.

How should I apply the serum for best results?

Use a few drops applied to clean, dry skin; gently dab and smooth across face and neck with fingertips. A small amount goes a long way—3 to 4 drops usually suffice—so pair it with your preferred moisturizer and sunscreen during daytime routines.

• Apply 3–4 drops to palm, then dab onto face and neck.
• Use morning and/or evening as directed by your regimen.
• Follow with moisturizer and SPF in daytime routines.

What sensory and practical details should I expect?

The serum has a lightweight texture that absorbs quickly and leaves a moist, smooth finish. Many users experience a cool tingling on application — an indication of active ingredients engaging the skin — followed by a supple, refined surface.

• Light, fast-absorbing botanical serum texture.
• May produce a temporary tingling sensation at first use.
• Packaged as a 1 fl oz dropper bottle for measured application.

Who is this for: iS CLINICAL Active Serum is ideal for anyone seeking a concentrated, multi-tasking treatment to improve texture, even skin tone, and support clearer-looking skin—suitable for all ages and most skin types. Choose this serum if you want a clinically-inspired, botanical-forward formula that acts quickly yet integrates into daily routines; if your skin is highly reactive, perform a patch test or consult a skincare professional before regular use.
