What the product description says

“Jet Lag Deep Hydration Serum”

Source: Summer Fridays

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: alanine, arginine.

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: arginine, squalane.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl glucosamine, ceramide np, palmitoyl tripeptide-38, panthenol

It can be itself be irritating though.~0.55–0.85%

Concentration of 4-6% is better for helping with acne and balancing the sebum production~0.45–0.65%

Anti-aging

Side benefit · Centella asiatica extract, Palmitoyl tripeptide-38 + 7 more

Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains acetyl glucosamine.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: aspartic acid, centella asiatica extract, palmitoyl tripeptide-38, serine, threonine.

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.

Centella asiatica extractKey activeEffect: MediumA 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.~0.55–0.85%

Evens skin tone

Side benefit · Acetyl glucosamine, Alanine + 1 more

Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: acetyl glucosamine

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: alanine.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

AlanineEffect: LowAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~0.3–0.5%

Anti-oxidation

Side benefit · Centella asiatica extract, Laminaria digitata extract

May help

This product contains antioxidants (centella asiatica extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Product summary

"Summer Fridays - Jet Lag Deep Hydration Serum" is effective for: Anti-aging, Moisturizing and Evens skin tone

Ingredient callouts

Ceramides (ceramide np 0.60% - 0.90%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
Peptides (palmitoyl tripeptide-38 0.45% - 0.70%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, 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 theynare helpful. Peptides 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.
An effective concentration of Panthenol (pro-vitamin B5) - about 0.60% - 0.90%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
Humectants (sodium lactate 0.25% - 0.50%, histidine 0.30% - 0.50%, alanine 0.30% - 0.50%, glycine 0.30% - 0.50%, pca 0.30% - 0.60%, aspartic acid 0.30% - 0.60%, arginine 0.35% - 0.60%, acetyl glucosamine 0.40% - 0.60%, panthenol 0.60% - 0.90%, sodium pca 0.70% - 1.05%, avena sativa kernel flour 1.10% - 1.40%, sodium hyaluronate 1.20% - 1.40% and glycerin 3.00% - 3.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
