In briefChecked October 2026
We rank Kollagen Intensiv first among anti-aging face creams. It's a cream for the skin, not an oral supplement. Its lead ingredient, the SYN-COLL peptide, rests on short studies run by the supplier and the brand, none published in a peer-reviewed journal. The cream also has retinol, which has better independent evidence for fine wrinkles, although the amount isn't disclosed. A 67-day money-back guarantee covers unused product.
📚 Key reference: The strongest independent evidence belongs to retinol, not the lead peptide. In a randomized trial, a 0.4% retinol lotion reduced fine wrinkles across 24 weeks. Kafi et al., 2007, Arch Dermatol

📰 The Research Behind It
Kollagen Intensiv itself has not been the subject of a published trial. The supplier and an unnamed 84-day study cited by the brand are the sources of SYN-COLL's wrinkle data. Reviews of cosmetic peptides (Schagen 2017, for one) say this kind of evidence comes from supplier studies and trade publications, not published randomized trials.
A peptide and retinol combined in one face cream, used for two to three months, is what Kollagen Intensiv offers. That timeline outlasts the 67-day refund window, so if you want to keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery. SYN-COLL, the headline ingredient, relies on unpublished supplier and brand studies. Retinol carries the best independent evidence, and its concentration isn't disclosed.
Below we cover the ingredients in Kollagen Intensiv, what the SYN-COLL claims are based on, side effects and the guarantee terms. Please read the whole review before you decide.

About Kollagen Intensiv
The brand behind this cream is Skinception, and you put it on morning and evening. Per the official product page, the main active is the SYN-COLL peptide (palmitoyl tripeptide-5). Also listed: retinol, retinyl palmitate, three more peptides (palmitoyl oligopeptide, palmitoyl tetrapeptide-3, acetyl hexapeptide-3), hyaluronic acid, glycerol, shea butter, soybean oil, vitamin E, green tea extract and two kinds of vitamin C. No percentages appear. One 2.0 oz jar is described as a month's 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, One by One
Because ingredient percentages aren't published, we can't set concentrations against the amounts used in studies. What follows is the intended role of each listed ingredient.
SYN-COLL (Palmitoyl Tripeptide-5)Signal Peptide
SYN-COLL is a small synthetic peptide designed to tell skin cells (fibroblasts) to produce collagen. Supplier studies report reduced wrinkle depth, and lab studies show more collagen production. Published human trials haven't shown this, and nothing published says how well it gets into skin from this cream.
Retinol and Retinyl PalmitateVitamin A
Retinol has the strongest support of any ingredient here. An independent randomized trial of 0.4% retinol lotion found fewer fine wrinkles and more procollagen (a collagen precursor) after 24 weeks. This cream doesn't disclose its retinol concentration. Retinyl palmitate is a gentler form of vitamin A.
Other PeptidesSignal Peptides
Palmitoyl oligopeptide, palmitoyl tetrapeptide-3 and acetyl hexapeptide-3 are widely used cosmetic peptides. The evidence for them comes mostly from ingredient suppliers and not from independent trials.
Hyaluronic Acid, Glycerol and Shea ButterHydration
These moisturizers keep water in the skin, so fine lines can look less visible while the skin stays hydrated.
Vitamin C (two forms), Vitamin E and Green TeaAntioxidants
Skincare often uses these antioxidants. Vitamin C plays a part in collagen production, but the cream doesn't disclose which forms or how much.
Soybean oil is listed too. You apply the cream to your skin and don't take it by mouth.
Where we have reservations
For balance, here are the weak points of Kollagen Intensiv that buyers should keep in mind:
→The finished cream has no published trial, and the SYN-COLL data come from supplier and brand studies
→In the first weeks, retinol can bring dryness, redness and flaking
→Many drugstore products with comparable ingredients cost the same or less, and the evidence does not justify a premium
→Percentages go undisclosed for every ingredient, retinol included
When Results Might Show Up
These timings follow the brand's own guidance, as no published trial of this product sets a timeline. Results differ from person to person:
1
Weeks 1–4: Adjusting
A moisturizer can make skin feel smoother fast. Retinol may cause dryness or peeling at the start, and there are no reliable data on wrinkle changes this early.
2
Weeks 8–12: Time to Judge
The brand's own study lasted 84 days (12 weeks), so check fine lines at 8–12 weeks. Changes in the independent retinol trial were measured at 24 weeks.
⚠️ Important: Individual results differ. The brand supplies these timelines as estimates, and no trial produced them. The 67-day guarantee covers unused product sent back in its original container (see below).
What the research says
Trial of this product: None published. The brand points to an unnamed 84-day study and an 'up to 354%' figure, with no sample size or methods.
Ingredients: The supplier, not a peer-reviewed journal, is the source of SYN-COLL's wrinkle data, which includes a one-month study in Chinese volunteers. For fine wrinkles, retinol has independent randomized-trial evidence.
Label amounts: No percentage is disclosed for any ingredient, retinol included.
Guarantee: It lasts 67 days. You send back unused product in its original container, and shipping costs aren't refunded.

Considerations
✗The finished cream has no published trial, and the SYN-COLL data come from the supplier and the brand
✗Concentrations are undisclosed, retinol's included

✗About $59.95 a month, above many retinol creams
Who Needs Extra Care With Kollagen Intensiv
✗People who are pregnant, trying to conceive or breastfeeding (ask a doctor before using any retinol product)
✗Anyone with very sensitive or reactive skin, eczema or rosacea, who should patch-test first
✗People using prescription skin treatments, such as prescription retinoids, who haven't checked with their doctor
✗People hoping for an instant or certain result, since topical products need weeks of steady use
✗People who won't wear sunscreen daily while using retinol
How Safe Is Kollagen Intensiv?
This cream is for external use only. The finished product has no published safety study, and the chief risks are skin irritation from retinol and allergic reactions to single ingredients.
What to Expect
Dryness, redness, flaking or stinging are common with retinol in the first weeks. Retinoids can make skin more sensitive to the sun, so wear sunscreen every day. If your skin is reactive, patch-test first.
Talk to your doctor first if:
● You have a skin condition or use prescription skin treatments
● You are allergic to any listed ingredient
● You're pregnant, trying to conceive or breastfeeding
● You are younger than 18

Our Final Verdict on Kollagen Intensiv
A peptide and retinol combined in one face cream, used for two to three months, is what Kollagen Intensiv offers. That timeline outlasts the 67-day refund window, so if you want to keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery. SYN-COLL, the headline ingredient, relies on unpublished supplier and brand studies. Retinol carries the best independent evidence, and its concentration isn't disclosed.
Best for: adults who'd like a peptide and retinol in a single jar and can stick with it for two to three months. Because that outlasts the 67-day refund window, decide by about day 55 so returns arrive within 67 days of delivery.
Not for: people who are pregnant or breastfeeding and haven't had medical advice, people with very reactive skin, and anyone expecting results proven in a product trial.
*Results may differ between people. These statements have not been evaluated by the FDA. Not intended to diagnose, treat, cure or prevent any disease. Read the full disclaimer
No, the cream has no collagen in it. The SYN-COLL peptide is marketed for the look of fine lines, and lab studies suggest it acts on collagen, though published human trials haven't shown that. The retinol has the better independent evidence: a randomized trial found that retinol lotion reduced fine wrinkles and raised procollagen in aged skin across 24 weeks.
It's a cream for external use only. At first, retinol can cause dryness, redness and flaking, and it makes skin more sensitive to the sun, so wear sunscreen daily and patch-test if your skin is reactive. The finished product has no published safety study.
The cream has no published trial. The brand's own study lasted 84 days, so use it twice a day for 8–12 weeks before you judge fine lines.
Use the official website, where the 67-day guarantee applies. You send back unused product in its original container, and shipping costs aren't refunded. The terms don't say they extend to purchases from other sellers.
Because it contains retinol, anyone pregnant, trying to conceive or breastfeeding should check with a doctor first. If you have eczema, rosacea or very reactive skin, patch-test before use.
