Kollagen Intensiv is a topical anti-aging face cream (not an oral supplement) and our top pick among anti-aging face creams. Its headline ingredient, the SYN-COLL peptide, is backed by short supplier- and brand-run studies that haven't been published in a peer-reviewed journal. It also contains retinol, which has better independent evidence for fine wrinkles, though the amount isn't disclosed. It comes with a 67-day money-back guarantee for unused product.
📚 Key reference: Retinol, not the headline peptide, has the strongest independent evidence: a randomized trial found 0.4% retinol lotion reduced fine wrinkles over 24 weeks. Kafi et al., 2007, Arch Dermatol

🔬No published trial of the cream
📰 The Research Behind It
No trial of Kollagen Intensiv itself has been published. SYN-COLL's wrinkle data come from the ingredient supplier and an unnamed 84-day study the brand cites, and reviews of cosmetic peptides (e.g. Schagen 2017) describe this evidence as coming from supplier studies and trade publications rather than published randomized trials.
Kollagen Intensiv may suit someone who wants a peptide-plus-retinol face cream in one product and is willing to give it two to three months. That runs past the 67-day refund window, so to keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery. The headline SYN-COLL claims rest on unpublished supplier and brand studies, so the retinol is the part with the best independent evidence, and its concentration isn't disclosed.
In this review we go through what's in Kollagen Intensiv, what the SYN-COLL claims are based on, the side effects and the guarantee terms. Read the full analysis below before making a decision.

What Is Kollagen Intensiv?
Kollagen Intensiv is a topical anti-aging face cream sold by Skinception, applied morning and evening. The official product page lists the SYN-COLL peptide (palmitoyl tripeptide-5) as its headline active, alongside retinol and retinyl palmitate, other peptides (palmitoyl oligopeptide, palmitoyl tetrapeptide-3, acetyl hexapeptide-3), hyaluronic acid, glycerol, shea butter, soybean oil, vitamin E, two forms of vitamin C and green tea extract. No percentages are given. A 2.0 oz jar is described as a one-month supply.
*Kollagen Intensiv is a topical cosmetic, not a dietary supplement. Not intended to diagnose, treat, cure or prevent any disease. Statements not evaluated by the FDA.
Active Ingredients — Full Scientific Breakdown
Ingredient percentages are not published, so we can't compare concentrations with the amounts used in studies. Below is what each listed ingredient is meant to do.
SYN-COLL (Palmitoyl Tripeptide-5)Signal Peptide
SYN-COLL is a small synthetic peptide designed to signal skin cells (fibroblasts) to make collagen. Supplier studies report reduced wrinkle depth and lab studies show more collagen production, but this hasn't been shown in published human trials, and how well it penetrates skin from this cream isn't published.
Retinol and Retinyl PalmitateVitamin A
Retinol is the best-supported ingredient here: an independent randomized trial found 0.4% retinol lotion reduced fine wrinkles and increased procollagen (a collagen precursor) over 24 weeks. The retinol concentration in this cream isn't disclosed. Retinyl palmitate is a milder vitamin A form.
Other PeptidesSignal Peptides
Palmitoyl oligopeptide, palmitoyl tetrapeptide-3 and acetyl hexapeptide-3 are common cosmetic peptides. Their evidence mostly comes from ingredient suppliers, not independent trials.
Hyaluronic Acid, Glycerol and Shea ButterHydration
Moisturizing ingredients that hold water in the skin and can make fine lines look less visible while the skin is hydrated.
Vitamin C (two forms), Vitamin E and Green TeaAntioxidants
Antioxidants commonly used in skincare. Vitamin C is involved in collagen production, but the forms and amounts here aren't disclosed.
Also listed: soybean oil. Kollagen Intensiv is applied to the skin; it is not taken by mouth.
📋 Our Editorial Concerns
In the interest of balance, here are the limitations of Kollagen Intensiv that we think buyers should know:
→No published trial of the finished cream; the SYN-COLL data come from supplier and brand studies
→Retinol can cause dryness, redness and flaking in the first weeks
→The price is similar to or higher than many drugstore products with comparable ingredients, and the evidence does not justify a premium
→Ingredient percentages, including retinol, are not disclosed
Results Timeline: What to Expect
Based on the brand's own guidance; no published trial of this product sets a timeline. Individual results vary:
1
Weeks 1–4: Getting Used to It
Moisturizers can make skin feel smoother quickly. Retinol may cause dryness or peeling at first; there's no reliable data on wrinkle changes this early.
2
Weeks 8–12: When to Judge
The brand's own study ran 84 days (12 weeks), so judge fine lines at 8–12 weeks. In the independent retinol trial, changes were measured at 24 weeks.
⚠️ Important: Results vary. These timelines are the brand's estimates, not trial results. The 67-day guarantee covers unused product returned in its original container (see below).
🔬 What the Evidence Actually Shows
Trial of the product itself: None published. The brand cites an unnamed 84-day study with an 'up to 354%' figure, with no sample size or methods.
Ingredients: SYN-COLL's wrinkle data come from the supplier (including a one-month study in Chinese volunteers) and aren't peer reviewed. Retinol has independent randomized-trial evidence for fine wrinkles.
Amounts on the label: No percentages are disclosed for any ingredient, including retinol.
Guarantee: 67 days. Return unused product in its original container; shipping costs aren't refunded.

Is Kollagen Intensiv Safe?
Kollagen Intensiv is a topical cream for external use only. There is no published safety study of this finished product; the main risks are skin irritation from retinol and allergic reactions to individual ingredients.
✓ What to Expect
Retinol commonly causes dryness, redness, flaking or stinging in the first weeks. Retinoids can increase sun sensitivity, so use daily sunscreen. Patch-test first if your skin is reactive.
⚠️ Consult Your Doctor If:
● You have a skin condition or use prescription skin treatments
● You have known allergies to any listed ingredient
● You are pregnant, trying to conceive or breastfeeding
● You are under 18 years of age

Best for: adults who want a peptide-plus-retinol face cream in one jar and are willing to give it two to three months. That runs past the 67-day refund window, so to keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery.
Not for: anyone pregnant or breastfeeding without medical advice, anyone with very reactive skin, or anyone expecting results proven in a product trial.

It doesn't contain collagen. Its SYN-COLL peptide is marketed for the look of fine lines; lab studies suggest it acts on collagen, but that hasn't been shown in published human trials. Its retinol has better independent evidence: a randomized trial found retinol lotion reduced fine wrinkles and increased procollagen in aged skin over 24 weeks.
It's a topical cream for external use only. The retinol can cause dryness, redness and flaking at first and makes skin more sun-sensitive, so use daily sunscreen and patch-test if your skin is reactive. There is no published safety study of the finished product.
There's no published trial of the cream. The brand's own study ran 84 days, so give it 8–12 weeks of twice-daily use before judging fine lines.
From the official website, where the 67-day guarantee applies: return unused product in its original container; shipping costs aren't refunded. The terms don't say they cover purchases from other sellers.
Anyone pregnant, trying to conceive or breastfeeding should check with a doctor before using Kollagen Intensiv because it contains retinol. People with eczema, rosacea or very reactive skin should patch-test first.
