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: algae extract, 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, algae extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, linoleic acid, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, panthenol

Histidine hclKey activeEffect: HighA salt of an amino-acid that helps attract water to the upper layer of the skin. Might be helpful in restoring the skin barrier function~0.2–0.35%

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: retinyl palmitate.

Retinyl palmitateKey activeEffect: MediumThree 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~0.25–0.5%

This product contains acetyl hexapeptide-8, centella asiatica extract, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, retinyl palmitate, vitis vinifera seed extract. 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.

Vitis vinifera seed extractKey activeEffect: MediumA plant extract that contains resveratrol and other anti-oxidant compounds that can help neutralize free radicals, reduce inflammation in skin and even out its tone. Can be also used to stabilize the product formulation~0.3–0.6%

Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.25–0.5%

Sodium ascorbyl phosphateEffect: Low, below effective doseA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.3–0.5%

Ascorbyl palmitateEffect: Low, below effective doseBeing 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.~0.25–0.5%

Anti-blemishAnti-oxidationAnti-aging

A stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C

Product summary

Based on the ingredient list, "Peter Thomas Roth - Mega-Rich Intensive Anti-Aging Cellular Creme" can work well for skin moisturization. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin, sodium hyaluronate, sodium pca, soluble collagen and butylene glycol 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). Ceramide 3, beeswax, caprylic/capric triglyceride, dimethicone and squalane 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.

Ingredient callouts

This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this moisturizer it is used for stabilizing other ingredients in the formulation. In this concentration (0.30% - 0.55%) it cannot have a noticeable benefit for the skin.
This moisturizer includes a form of Retinoids (vitamin A) - retinyl palmitate 0.30% - 0.60%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
As a plus, this moisturizer also contains Ceramides (ceramide 3 0.30% - 0.60%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
This moisturizer also contains Peptides (palmitoyl oligopeptide 0.55% - 0.85%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, 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 they are helpful. Peptides 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.

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: allantoin, butyrospermum parkii butter, vitamin c and vitamin e

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
