iS CLINICAL Active Serum lightweight face serum 1 fl oz — evens tone, smooths texture

iS CLINICAL Active Serum is a fast-acting, multi-tasking botanical face serum that helps even skin tone, smooth texture, and address blemish-prone skin.

Designed as the brand’s signature treatment, Active Serum blends targeted actives and botanical extracts to deliver both immediate sensation and ongoing skin-refining results. Its lightweight formula absorbs quickly, leaving skin feeling hydrated and looking more uniform without heavy residue. Many users report visible improvement within days, though ongoing use supports longer-term texture and tone changes.

How quickly will I notice a difference when I use Active Serum?

Results often begin to show within a few days for some users, especially improvements in surface texture and radiance. Continued nightly or twice-daily use builds cumulative benefits for tone, fine lines, and blemish-prone concerns over weeks.

• Initial cooling or tingling on application signals active ingredients engaging the skin.
• Visible smoothing and brighter tone can occur within days for many users.
• Consistent use over 4–12 weeks supports longer-term reduction in fine lines and uneven tone.

What skin types can safely use this serum?

Active Serum was formulated for all skin types and ages, including oily and blemish-prone complexions. Its botanical base delivers moisture without heaviness, making it suitable under other treatments or moisturizers.

• Lightweight texture works well under daily SPF and makeup.
• Non-greasy hydration supports oily and combination skin.
• Can be layered with prescribed acne or anti-aging regimens—consult your skincare professional when combining actives.

How should I apply Active Serum for best results?

Use 3–4 drops on clean skin, gently dabbing and smoothing across the face and neck with fingertips. Allow the serum to absorb before applying moisturizer or sunscreen; a subtle tingling may occur on first use.

• Apply to dry, cleansed skin morning and/or night as tolerated.
• Use light pressure and upward strokes to distribute evenly.
• Follow with moisturizer and daytime SPF to protect results.

Are there any sensations or side effects I should expect?

Some users experience a cool tingling when the serum is applied — this is a common response to active botanical and clinical ingredients. If persistent irritation, redness, or discomfort occurs, pause use and consult a dermatologist.

• Tingling usually fades as skin acclimates.
• Discontinue if severe irritation or allergic reaction appears.
• Patch-test a small area if you have sensitive skin or are combining strong actives.

Who is this for: iS CLINICAL Active Serum is aimed at anyone seeking a concentrated, fast-acting treatment to smooth texture, help even skin tone, and support blemish-prone or aging skin. It’s a versatile pick for users who want a potent botanical serum that layers well with a clinical skincare routine and is appropriate for a wide range of ages and skin types.
