Peptides (acetyl tetrapeptide-17 0.15% - 0.25%, dipeptide-2 0.20% - 0.35%, palmitoyl tripeptide-1 0.25% - 0.45%, n-prolyl palmitoyl tripeptide-56 acetate 0.25% - 0.40%, palmitoyl tetrapeptide-7 0.30% - 0.50%, acetyl hexapeptide-8 0.25% - 0.45%, palmitoyl tripeptide-5 0.25% - 0.45%, dipeptide diaminobutyroyl benzylamide diacetate 0.25% - 0.45% and acetyl octapeptide-3 4.00% - 4.80%). 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.
Humectants (glycine 0.25% - 0.45%, acetyl hexapeptide-8 0.25% - 0.45%, glutamic acid 0.25% - 0.45%, alanine 0.25% - 0.45%, sodium hyaluronate 0.25% - 0.45%, imperata cylindrica root extract 0.65% - 0.95%, glycerin 4.50% - 5.50%, arginine 0.35% - 0.60% and acetyl octapeptide-3 4.00% - 4.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What does the product description say?

With eight potent peptides that work to support the skin's natural production of collagen, this serum helps to visibly reduce the look of wrinkles, neutralise free radicals and promote a more even toned and supple appearance.

This product contains acetyl hexapeptide-8, acetyl octapeptide-3, acetyl tetrapeptide-17, dipeptide diaminobutyroyl benzylamide diacetate, dipeptide-2, n-prolyl palmitoyl tripeptide-56 acetate, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5, serine, threonine. These ingredients might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

palmitoyl tripeptide-1 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

threonine 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: MEDIUM

An amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles

serine 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: MEDIUM

An amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles

Moisturizing

What does the product description say?

Gardenia stem cells works to minimise the effects of UV damage, and hyaluronic acid helps to restore lost volume and hydration.

Source: SpaceNK US

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, glycine soja protein.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, acetyl octapeptide-3, acetyl tetrapeptide-17, dipeptide diaminobutyroyl benzylamide diacetate, dipeptide-2, n-prolyl palmitoyl tripeptide-56 acetate, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5

superoxide dismutase 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: HIGH

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

imperata cylindrica root extract 0.65% - 0.95%

Irritation risk:

Concentration: Effectiveness: HIGH

A plat extract that might help neutralize free radicals in skin and attract water to its upper layer

isoleucine 0.2% - 0.4%

Irritation risk:

Concentration: Effectiveness: HIGH

An amino acid that can help attract water to the upper layer of the skin and support skin's barrier function

Anti-oxidation

This product contains antioxidants (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).

The following ingredients - imperata cylindrica root extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

superoxide dismutase 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: HIGH

imperata cylindrica root extract 0.65% - 0.95%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A plat extract that might help neutralize free radicals in skin and attract water to its upper layer

taurine 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: LOW

Could be helpful in reducing inflammation in skin, evening out the skin tone and neutralizing free radicals, but more research is needed to confirm its effectiveness

Evens skin tone

What does the product description say?

With eight potent peptides that work to support the skin's natural production of collagen, this serum helps to visibly reduce the look of wrinkles, neutralise free radicals and promote a more even toned and supple appearance.

Source: SpaceNK US

This product contains ingredients (alanine, glycine soja protein) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.

alanine 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: LOW

An 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

glycine soja protein 0.25% - 0.5%

Irritation risk:

Concentration: Effectiveness: LOW

A plant extract that helps to attract water to the upper layer of the skin and soften it. It might be helpful in neutralizing free radicals. It might be somewhat helpful for evening out the skin tone. It might be able to support elastin production but solid research is lacking

taurine 0.25% - 0.45%

Irritation risk:

Concentration: Effectiveness: LOW

Could be helpful in reducing inflammation in skin, evening out the skin tone and neutralizing free radicals, but more research is needed to confirm its effectiveness

Key Actives

camellia sinensis leaf extract 0.25% - 0.5%

Irritation risk:

Works for: Antibacterial, Anti-oxidation, Anti-aging, Moisturizing, Anti-blemish, Evens skin tone

Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation

allantoin 0.2% - 0.4%

Irritation risk:

Works for: Moisturizing, Anti-inflammatory, Reduces irritation, Reduces redness, Anti-blemish, Exfoliation

Helps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated
