Product Summary
"Peter Thomas Roth - Peptide 21 Lift & Firm Moisturizer" is a well-rounded moisturizing product. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Acetyl hexapeptide-8, acetyl octapeptide-3, dextran, glycerin and mannitol 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, tripeptide-1, phytosterols and dimethicone) 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 (trifluoroacetyl tripeptide-2 0.25% - 0.45%, palmitoyl tripeptide-5 0.45% - 0.65%, palmitoyl tripeptide-1 0.30% - 0.50%, palmitoyl tetrapeptide-7 0.30% - 0.55%, palmitoyl oligopeptide 0.30% - 0.60%, palmitoyl hexapeptide-19 0.25% - 0.45%, palmitoyl hexapeptide-12 0.30% - 0.55%, tripeptide-10 citrulline 0.40% - 0.60%, tripeptide-1 0.25% - 0.50%, hexapeptide-11 0.55% - 0.80%, dipeptide diaminobutyroyl benzylamide diacetate 0.50% - 0.75%, acetyl tetrapeptide-9 0.25% - 0.50%, acetyl tetrapeptide-2 0.25% - 0.45%, acetyl tetrapeptide-11 0.35% - 0.65%, acetyl octapeptide-3 0.25% - 0.45%, acetyl hexapeptide-8 0.30% - 0.60% and acetyl hexapeptide-1 0.40% - 0.60%). 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.

Anti-aging
What does the product description say?
Peptide 21 Lift & Firm Moisturizer
Source: From product name
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains palmitoyl hexapeptide-12.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-1, acetyl hexapeptide-8, acetyl octapeptide-3, acetyl tetrapeptide-11, acetyl tetrapeptide-2, acetyl tetrapeptide-9, dipeptide diaminobutyroyl benzylamide diacetate, hexapeptide-11, palmitoyl hexapeptide-19, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5, tetradecyl aminobutyroylvalylaminobutyric urea trifluoroacetate, trifluoroacetyl tripeptide-2, tripeptide-1, tripeptide-10 citrulline.
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.

Moisturizing
What does the product description say?
Peptide 21 Lift & Firm Moisturizer
Source: From product name
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:
dextran, 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: dimethicone, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-1, acetyl hexapeptide-8, acetyl octapeptide-3, acetyl tetrapeptide-11, acetyl tetrapeptide-2, acetyl tetrapeptide-9, dipeptide diaminobutyroyl benzylamide diacetate, hexapeptide-11, palmitoyl hexapeptide-12, palmitoyl hexapeptide-19, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5, trifluoroacetyl tripeptide-2, tripeptide-1, tripeptide-10 citrulline

Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Used mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin
Anti-oxidation
This product contains antioxidants (cereus grandiflorus flower extract, squalene) 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.
A cactus extract that can help neutralize free radicals because it contains a chemical compound called betacyanins and flavonolglycosides. Can help make the surface of the skin dryer helping make pores look smaller for a very short period of time. The concentrations usually used in cosmetics are too small to have any effect
