Full Review
Every brand has a 'super' something. Super hydrating. Super brightening. Super whatever marketing decided would move units this quarter. But iS Clinical's Super Serum Advance+ was named with unusual precision. This is the brand's most concentrated treatment serum — 15% L-ascorbic acid combined with bioidentical Tripeptide-1 (the GHK copper peptide fragment), isolated centella triterpenoids, arbutin, and hyaluronic acid — all in a seventeen-ingredient formula that is cleaner and more focused than most products half its potency.
The star pairing here is vitamin C and GHK peptide, and understanding why they work together explains why this serum has found a genuine niche in scar management. L-ascorbic acid is a cofactor for prolyl hydroxylase and lysyl hydroxylase — the enzymes that stabilize collagen's triple helix structure. Without adequate vitamin C, collagen production falters. Tripeptide-1, meanwhile, triggers a different phase of the process entirely. The GHK fragment signals fibroblasts to ramp up collagen, elastin, and glycosaminoglycan production while also stimulating the tissue-remodeling pathways that turn disorganized scar tissue into more organized, normal-looking skin.
Most vitamin C serums can brighten the dark discoloration that scars leave behind. This one can also help improve the textural component — the raised or depressed areas where collagen was deposited haphazardly during wound healing. That dual-action (color plus texture) is what gives it clinical credibility for scar treatment that single-ingredient serums can't match.
The centella triterpenoids — asiaticoside, asiatic acid, and madecassic acid — appear again here, individually isolated as in the Hydra-Cool Serum. Their anti-inflammatory and wound-healing properties provide the foundation for the peptide and vitamin C to work on. You cannot effectively remodel tissue that is actively inflamed, and the centella component ensures the inflammatory environment is managed while the constructive actives do their work.
Arbutin adds the brightening dimension, inhibiting tyrosinase through a mechanism complementary to vitamin C. For those dealing with post-inflammatory hyperpigmentation — the dark marks left behind by acne, injuries, or procedures — this dual approach offers meaningful depigmenting activity.
On the skin, this serum is notably gentler than the Pro-Heal. The absence of denatured alcohol is immediately apparent — no sting, no burning, no tightness. A mild tingle from the 15% ascorbic acid is possible, but the hyaluronic acid, glycerin, and centella triterpenoids buffer the experience considerably. The texture is light and slightly viscous, absorbing within a minute with no residue. Under sunscreen, it is invisible.
Results follow a predictable vitamin C trajectory for the first month: brightening by week one, improved tone evenness by week three, enhanced radiance by week four. The peptide and scar-remodeling benefits take longer — twelve weeks or more for visible changes in scar texture. This is not a quick fix; it is a sustained investment. And given the six-month PAO, you are looking at roughly two bottles to see a full scar-treatment cycle through.
The price — $177 for one ounce — is identical to the Pro-Heal and represents iS Clinical's premium tier. For a vitamin C serum, this is luxury territory. The value argument is strongest for those who need the scar-treatment dimension and would otherwise be purchasing separate vitamin C, peptide, and brightening products. For those who simply want a good vitamin C serum, the ingredient list is compelling but the price may not be.
What earns the Super Serum its name is the breadth of what it accomplishes in a single step. This is not a vitamin C serum with some peptides thrown in as marketing garnish. The GHK peptide is a deliberate, research-backed addition that gives this product a treatment profile you genuinely cannot replicate with a vitamin C serum plus a peptide cream. The whole is greater than the sum of its parts — and in a market glutted with 'super' products, that is a distinction worth noting.
Formula
Ingredients
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| L-Ascorbic Acid (Vitamin C) 15% (15%) | At 15% concentration, provides the antioxidant and collagen-stimulating backbone of this formula — but here it works in tandem with Tripeptide-1 to address both free radical protection and structural repair simultaneously, creating a more comprehensive anti-aging effect than vitamin C alone. | well-established |
| Tripeptide-1 (Copper Tripeptide-1/GHK) | The GHK peptide fragment stimulates collagen, elastin, and glycosaminoglycan synthesis while promoting wound healing — combined with vitamin C's collagen-boosting activity, this dual approach addresses collagen production from both a signaling and a cofactor pathway. | promising |
| Centella Asiatica Triterpenoids (Asiaticoside, Asiatic Acid, Madecassic Acid) | The same isolated triterpenoid trio used in iS Clinical's Hydra-Cool Serum — providing targeted anti-inflammatory and wound-healing support that makes this vitamin C serum uniquely suitable for sensitized or post-procedure skin. | well-established |
| Arbutin | Inhibits tyrosinase to reduce melanin production, working alongside vitamin C's brightening action through a complementary pathway — the dual mechanism creates more effective hyperpigmentation correction than either ingredient alone. | well-established |
| Hyaluronic Acid | Listed third in the formula, providing substantial hydration that offsets any potential drying from the ascorbic acid — the full-weight hyaluronic acid (not just sodium hyaluronate) offers both surface and deeper dermal hydration. | well-established |

Evidence
Science
The Science
The combination of L-ascorbic acid and Tripeptide-1 (GHK peptide) in this formula represents a clinically informed approach to collagen management. L-ascorbic acid is an essential cofactor for prolyl and lysyl hydroxylase, the enzymes required for stable collagen cross-linking. A review in Nutrients (2017) confirmed that topical vitamin C at 10-20% concentration promotes collagen gene expression and provides photoprotection through direct free radical scavenging.
Tripeptide-1 (glycyl-L-histidyl-L-lysine, or GHK) has been extensively studied for its tissue-remodeling properties. Research published in the journal BioMed Research International documented that GHK stimulates collagen synthesis, elastin production, glycosaminoglycan synthesis, and growth factor secretion by fibroblasts. Notably, GHK also modulates metalloproteinase activity — the enzymes responsible for collagen breakdown — helping to balance synthesis and degradation in scarred tissue. This remodeling capability is what distinguishes GHK-containing products from simple anti-aging serums.
The centella triterpenoids (asiaticoside, asiatic acid, madecassic acid) provide the anti-inflammatory environment necessary for effective tissue remodeling. Their activity through TGF-β/Smad and NF-κB signaling pathways has been documented in multiple dermatological studies. In the context of scar management, their ability to modulate inflammatory cytokines while supporting collagen synthesis makes them natural partners for the GHK peptide.
Arbutin's tyrosinase-inhibiting mechanism offers a safer alternative to hydroquinone for addressing post-inflammatory hyperpigmentation. Combined with vitamin C's inhibition of melanin synthesis at a different enzymatic step, the formula provides dual-mechanism brightening with a favorable safety profile for extended use.

Dermatologist Perspective
Dermatologists frequently recommend Super Serum Advance+ as part of scar management protocols, particularly for post-acne scarring and post-surgical scar improvement. Board-certified dermatologists note that the combination of 15% L-ascorbic acid with GHK peptide addresses both the pigmentary and textural components of scarring — a dual-action approach that single-ingredient products cannot replicate. The alcohol-free, fragrance-free formulation makes it suitable for use on healing skin, and it is commonly incorporated into post-procedure home care regimens alongside in-office treatments like microneedling and fractional lasers.
Guidance
Usage Guide
How to Use
Apply 3-4 drops to clean, dry skin each morning. Press gently into the face and neck with fingertips. Allow 1-2 minutes to absorb before applying moisturizer and sunscreen. For scar treatment, can also be applied to specific scar areas in the evening. For optimal scar results, use consistently for a minimum of 12 weeks. Store in a cool, dark place and use within six months of opening.
Value Assessment
At $177 for 1 fl oz, the Super Serum commands the same premium as the Pro-Heal. A 0.5 fl oz option at $104 provides a lower-commitment entry point. The value proposition is strongest for patients with active scar management needs — the combination of vitamin C, GHK peptide, centella triterpenoids, and arbutin in a single product replaces what would otherwise require three or four separate serums. For general anti-aging and brightening use, the price is harder to justify when effective vitamin C serums exist at lower price points. The six-month PAO also means waste is a real concern if usage is inconsistent.
Who Should Buy
Those dealing with post-acne scarring, post-inflammatory hyperpigmentation, or aging concerns who want a clinical-grade serum that addresses both texture and color. Excellent for patients looking for a pregnancy-safe vitamin C alternative to retinol-containing serums.
Who Should Skip
Budget-conscious consumers who primarily want vitamin C for general brightening — effective options exist at a fraction of this price. Also not ideal for those who need the CE ferulic acid network for maximum photoprotection, as this formula takes a different approach with peptides and centella instead.

Background
The Why
Super Serum Advance+ represents iS Clinical's flagship treatment serum, built to be the most comprehensive vitamin C product in the clinical skincare space. Where Pro-Heal Serum Advance+ was designed around healing inflammation, Super Serum was designed around rebuilding — using the GHK peptide to trigger the skin's own remodeling processes. The product gained particular recognition in the professional channel for its use in scar management protocols, where the combination of vitamin C, peptides, and centella triterpenoids offered a non-invasive adjunct to in-office treatments.

Myth vs. Reality
Myths
Myth
Vitamin C serums should sting to show they're working.
Reality
This serum is alcohol-free and formulated with hyaluronic acid, glycerin, and centella triterpenoids that buffer the 15% ascorbic acid. Minimal tingling is normal, but significant stinging usually indicates a compromised barrier — not potency.
Myth
Topical vitamin C and peptides can't meaningfully improve scars.
Reality
While deep scars may require in-office procedures, the GHK peptide in this formula has documented collagen-remodeling activity, and L-ascorbic acid is a cofactor for collagen synthesis. Together, they can improve the texture and color of superficial to moderate scarring over time.
FAQ
FAQ
What is the difference between iS Clinical Super Serum and Pro-Heal Serum?
Both contain 15% L-ascorbic acid, but they serve different purposes. Pro-Heal focuses on healing inflammation with retinol, vitamin E, and zinc sulfate — ideal for acne and sun damage. Super Serum focuses on structural repair with Tripeptide-1 (copper peptide) and centella triterpenoids — better for scar treatment, anti-aging, and collagen remodeling. Super Serum is also alcohol-free, making it gentler on sensitive skin.
Can iS Clinical Super Serum help with acne scars?
Yes — this is one of its primary clinical applications. The Tripeptide-1 (GHK peptide) stimulates collagen remodeling to improve scar texture, while 15% L-ascorbic acid addresses post-inflammatory hyperpigmentation and supports new collagen synthesis. Results for scar improvement typically require 12+ weeks of consistent daily use.
Is iS Clinical Super Serum safe during pregnancy?
Unlike the Pro-Heal Serum (which contains retinol), the Super Serum does not contain retinoids and is generally considered pregnancy-safe. However, always consult your OB-GYN or dermatologist before adding new actives during pregnancy.
How should I store iS Clinical Super Serum to prevent oxidation?
Store in a cool, dark place away from direct sunlight. The frosted glass bottle provides some protection, but keeping it in a drawer or medicine cabinet extends shelf life. Once opened, use within six months — L-ascorbic acid gradually oxidizes and loses potency. If the serum turns dark orange or brown, it has oxidized and should be replaced.
Can I use Super Serum Advance+ with retinol at night?
Yes — use the Super Serum in the morning for antioxidant protection and brightening, then apply your retinol product at night. This separation maximizes the benefits of both actives while minimizing potential irritation from layering them simultaneously.
