iS CLINICAL Super Serum Advance+ Vitamin C Face Serum, 1 fl oz — 15% L‑ascorbic Acid & Copper Tripeptide for Radiance

iS CLINICAL Super Serum Advance+ is a concentrated anti-aging serum that blends 15% L-ascorbic acid (vitamin C) with Copper Tripeptide-1 to target uneven tone, signs of aging, and the appearance of scars or fine stretch marks.

This next-generation serum pairs a high concentration of stabilized vitamin C with a copper peptide to support skin structure and surface radiance. The formula also includes botanical antioxidants and gentle brighteners to help defend against environmental stressors while promoting a more even-looking complexion. Designed for daily use under moisturizers and sunscreen, it fits into most morning or evening routines to complement targeted skincare goals.

How does this serum help reduce the look of scars and fine stretch marks?

The combination of 15% L-ascorbic acid and Copper Tripeptide-1 supports processes associated with skin texture and tone. These actives work alongside antioxidants and skin-brightening ingredients to address discoloration and the visual depth of scarring, while providing surface-level hydration.

• 15% vitamin C concentration for topical antioxidant support
• Copper Tripeptide-1 to help support skin resilience and appearance
• Botanical antioxidants reduce visible effects of environmental stress
• Light-refining brighteners promote more even-looking tone

Will this serum suit sensitive or combination skin types?

The formulation aims to be effective across a range of skin types, including combination and some sensitive skin. Because it contains a high-strength vitamin C, users with very reactive skin should introduce it gradually and patch-test first to gauge tolerance.

• Suitable for most skin types when introduced slowly
• Patch-test on inner forearm if you have reactive or barrier-compromised skin
• Use with a hydrating moisturizer to reduce potential dryness
• Apply sunscreen during daytime use to protect treated skin

How should I incorporate this serum into my skincare routine?

Apply Super Serum Advance+ after cleansing and toning, then follow with moisturizer and sunscreen during the day. A few drops are typically enough; gently pat into the face and neck until absorbed and allow a moment before layering other products.

• Use once daily (AM or PM) or as tolerated
• Apply to clean, dry skin—few drops across face and neck
• Follow with moisturizer; always use SPF in the morning
• Introduce gradually if new to concentrated vitamin C

What results can I expect and how long until I see changes?

Results vary by individual and depend on skin condition and consistency of use. Many users notice improved radiance and more even tone within weeks, while changes to texture and the appearance of scars or stretch marks typically develop over months of regular application.

• Early improvements: enhanced brightness and smoother-looking skin
• Ongoing use: gradual appearance changes in tone and texture
• Consistency matters—daily use yields best visible outcomes
• Combine with sun protection and complementary actives for better maintenance

Who is this for: iS CLINICAL Super Serum Advance+ is for anyone seeking a potent topical vitamin C treatment to address uneven pigmentation, early signs of aging, and the visual appearance of scarring or fine stretch marks. It is best suited to people ready to introduce a concentrated antioxidant serum into a consistent skincare routine and who will protect treated skin with daily sunscreen.
