iS CLINICAL Super Serum Advance+ Vitamin C Face Serum, 1 fl oz — 15% L-ascorbic Acid & Copper Tripeptide for Firmer-Looking Skin

iS CLINICAL Super Serum Advance+ is a concentrated anti-aging facial serum that blends 15% L‑ascorbic acid with Copper Tripeptide‑1 to support brighter, firmer-looking skin.

This serum pairs a high-strength vitamin C with a copper peptide to target uneven tone, surface texture and signs of aging. Formulated for daily use, the lightweight liquid absorbs quickly and is designed to work under moisturizers and sunscreens as part of a broader skin-care routine. It also includes botanical antioxidants and gentle brightening agents to help protect against environmental stressors and promote a more even complexion.

How does this serum support firmer-looking skin?

The combination of L‑ascorbic acid and Copper Tripeptide‑1 helps support the skin’s visible elasticity and texture. Vitamin C is included for its antioxidant profile and role in surface radiance, while the peptide is selected for its association with structural support. Results depend on consistent use and complementary skincare habits.

• 15% L‑ascorbic acid concentration for antioxidant activity and brightening support
• Copper Tripeptide‑1 to help target the appearance of firmness and texture
• Lightweight, fast-absorbing formula suitable for layering under cream or SPF

Can this serum help reduce the look of scars and stretch marks?

Clinical testing has shown potential improvements in the appearance of some scars and fine stretch marks when used as directed. The formula encourages surface renewal and supports a more even tone over time, though individual outcomes vary. For best results, use consistently and as part of a comprehensive regimen that includes sun protection.

• Targets uneven pigmentation and surface irregularities
• Supports appearance of smoother skin texture
• Recommended for use with SPF during daytime to protect renewed skin

Is this serum appropriate for my skin type and daily routine?

The formulation is designed to be compatible with a wide range of skin types, from normal to dry, combination and oily. Because it contains a potent form of vitamin C, those with very sensitive skin may wish to introduce it gradually or consult a professional. It works well under moisturizers and sunscreens and can be incorporated into morning or evening routines depending on tolerance and sun-exposure precautions.

• Suitable for most skin types; introduce slowly if sensitivity is a concern
• Can be applied after cleansing and before moisturizer and SPF
• Avoid mixing with harsh actives without guidance (patch-test recommended)

What results can I expect and when might I see them?

Visible improvements in tone and surface texture often become noticeable with regular use over several weeks, while deeper structural changes may take longer. Antioxidant protection is immediate at application, whereas brightening and smoothing effects accumulate with consistent application. Individual timelines depend on skin condition, frequency of use and supporting products like sunscreen.

• Antioxidant protection begins at first use
• Noticeable tone and texture changes typically appear after weeks of regular use
• Sustained improvements supported by routine sun protection and skincare regimen

Who is this for: This serum is aimed at adults seeking a high-strength vitamin C treatment to address uneven tone, early signs of aging and the appearance of minor scarring or stretch marks. It suits buyers who want a research-informed formula to slot into an established skincare routine and those prepared to use sun protection alongside active brightening products. If you have extremely sensitive skin or are unsure about combining active ingredients, consult a skincare professional before beginning use.
