Based on the ingredients included, "Peter Thomas Roth - Potent-C Moisturizer" 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 - Potent-C Moisturizer ticks this box. Carnosine, glycerin, hydrolyzed collagen, saccharomyces ferment filtrate and sodium hyaluronate 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 (ceramide np, glycine soja sterols, hydrolyzed collagen, jojoba esters and cetyl alcohol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this moisturizer to be medium. 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 tetrahexyldecyl ascorbate.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: carnosine, ferulic acid.
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.
Being a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.
A type of peptide. It attracts water to the upper layer of the skin. It can help neutralize free radicals in skin combatting the sun damage
A potent anti-oxidant that has been shown to be effective in neutralizing free radicals in skin. There seem to have a synergetic effect of ferulic acid, vitamin E and C, meaning that when the ingredients are used together, they enhance each other's ability protect the skin against free radicals. Ferulic acid also helps to stabilize other ingredients - including vitamins C and E. It can help to even out the skin tone. Ferulic acid is approved for use as a sunscreen ingredient in Japan in concentrations up to 10%
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
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
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
This product contains antioxidants (carnosine, ferulic acid, tetrahexyldecyl ascorbate) 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 - haematococcus pluvialis extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: tetrahexyldecyl ascorbate
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: ferulic acid.
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.

Potent-C 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:
carnosine, 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: glycine soja sterols, hydrolyzed collagen.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np
