"Medik8 - Copper PCA Peptides" is a well-rounded moisturizing product. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Aminobutyric acid, copper pca, glycerin, butylene glycol and portulaca oleracea extract in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, theobroma cacao seed butter, bis-diglyceryl polyacyladipate-2 and caprylic/capric triglyceride) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
This moistruizer also contains peptides (palmitoyl tripeptide-1 0.30% - 0.50% and palmitoyl tetrapeptide-7 0.25% - 0.50%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of peptides is, but it is very likely that peptides in skincare are helpful. They might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.

Moisturizing
What does the product description say?
The award-winning serum lifts and smooths to keep skin looking plump, soft and hydrated while reducing the appearance of fine lines and wrinkles.
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:
aminobutyric acid, copper pca.
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:
bis-diglyceryl polyacyladipate-2, caprylic/capric triglyceride.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1
Helps attract water to the upper layer of the skin

Anti-oxidation
This product contains antioxidants (dimethylmethoxy chromanol, superoxide dismutase) that can help neutralize
free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
An antioxidant enzyme that is naturally present in skin. It can help support skin barrier function and reduce inflammation in skin. It is used in topical medications for inflammatory skin conditions including atopic dermatitis (eczema) and psoriasis. There are three types of natural Superoxide Dismutase in human skin. The compound used in topical treatments and cosmetics are mimics of typically one of these natural variants
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.
The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
A plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.
