Product Summary
"Medik8 - Liquid Peptideses" is effective for: Anti-aging and Moisturizing
Ingredient callouts
- Peptides (heptapeptide-15 palmitate 0.05% - 0.20%, copper palmitoyl heptapeptide-14 0.05% - 0.25%, palmitoyl tetrapeptide-7 0.15% - 0.55%, palmitoyl tripeptide-38 0.10% - 0.45%, palmitoyl tripeptide-1 0.15% - 0.60%, pentapeptide-18 0.15% - 0.55%, tetrapeptide-21 0.15% - 0.60%, acetyl hexapeptide-8 0.15% - 0.60% and palmitoyl tripeptide-5 0.20% - 0.75%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
- An effective concentration of Panthenol (pro-vitamin B5) - about 1.60% - 2.40%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
- Humectants (heptapeptide-15 palmitate 0.05% - 0.20%, copper palmitoyl heptapeptide-14 0.05% - 0.25%, pantolactone 0.10% - 0.45%, acetyl hexapeptide-8 0.15% - 0.60%, carnosine 1.20% - 1.80%, panthenol 1.60% - 2.40%, sodium hyaluronate 2.00% - 3.00% and glycerin 4.30% - 6.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains heptapeptide-15 palmitate.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, carnosine, copper palmitoyl heptapeptide-14, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-38, palmitoyl tripeptide-5, pentapeptide-18, tetrapeptide-21.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
A type of peptide. It attracts water to the upper layer of the skin. It can help neutralize free radicals in skin combatting the sun damage
The copper palmitoyl heptapeptide-14 is a synthetic peptide developed by ingredient supplier Infinitec, which claims that it can increase collagen production in skin when combined with Heptapeptide-15 Palmitate. The complex was tested in vitro (in a lab) and in a clinical test with 30 volunteers, but the latter wasn't placebo-controlled. The manufacturer reported wrinkle reduction after 28 days of use, but the details of the study aren't publicly available.

Anti-oxidation
This product contains antioxidants (carnosine) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

A green micro-algae extract that might help neutralize free radicals in skin, but solid evidence is lacking. It helps to soften the upper layer of the skin
Moisturizing
What does the product description say?
Say 'no' to expression lines and 'yes' to a visibly smooth, plump and hydrated complexion.
Source: N/A
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
carnosine, glycerin.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, copper palmitoyl heptapeptide-14, heptapeptide-15 palmitate, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-38, palmitoyl tripeptide-5, panthenol, pentapeptide-18, tetrapeptide-21
