Product Summary
"Sarah Chapman - Platinum Pep8 Stem Cell Serum" is effective for: Moisturizing and Anti-oxidation
This product could be helpful for: Anti-aging, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- 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.

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.
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
A plat extract that might help neutralize free radicals in skin and attract water to its upper layer
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
Might help neutralize free radicals in skin. Is claimed to be able to improve the appearance of undereye darkness but evidence is missing. Can be an allergen and cause irritation
Helps attract water to the upper layer of the skin. Might have some anti-oxidant properties
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
A plant extract that might have some anti-oxidant and anti-inflammatory properties but evidence for effectiveness in skin is missing
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
Seaweed extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but good research is lacking at the moment
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.

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
