Based on the ingredients included, "Peter Thomas Roth - Un-Wrinkle Night" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Peter Thomas Roth - Un-Wrinkle Night ticks this box. Acetyl hexapeptide-8, acetyl octapeptide-3, panthenol, arginine and glycerin 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). Palmitoyl tetrapeptide-7, isocetyl stearate, persea gratissima oil, arginine and dimethicone in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
This moisturizer contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinol, glycolic acid.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, acetyl octapeptide-3, dipeptide diaminobutyroyl benzylamide diacetate, palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5.
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.
Two steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid

Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
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
Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.
This product can help reduce breakouts and clogged pores because it contains the following ingredient: retinol. This ingredient is used for treating acne and can have a noticeable effect.
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glycolic acid

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinol.
In addition, this product contains glycolic acid. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.
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.

The following ingredient is doing the exfoliating job in this product: glycolic acid, retinol.

Helps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated
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:
arginine, 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: arginine, dimethicone.
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, dipeptide diaminobutyroyl benzylamide diacetate, palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, panthenol
