Product Summary
Based on the ingredient list, "Rodial - Pink Diamond Magic Gel" can work well for skin moisturization. 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. Anhydroxylitol, glycerin, xylitylglucoside, glucose and hydrolyzed wheat protein 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 (dimethicone, dimethiconol, squalane, cyclopentasiloxane and ethylhexyl cocoate) 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
- We particularly like that there is a good concentration of Niacinamide (3.80% - 5.60%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and help improve the skin tone, reducing pigmentation marks.
- We like that this moisturizer contains peptides (decapeptide-22 0.15% - 0.50%, zinc palmitoyl nonapeptide-14 0.10% - 0.45% and palmitoyl decapeptide-21 0.15% - 0.50%). 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. Peptides 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.

Anti-aging
What does the product description say?
Key Benefits A day cream for enhancing and nourishing the complexion Works to tighten the facial contours Vitamin C helps to strengthen and brighten skin Minimises the look of fine lines and age spots Light-diffusing diamond powder provides a natural glow UK200023501

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains decapeptide-22, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl decapeptide-21, zinc palmitoyl nonapeptide-14.
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.

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
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: dimethylmethoxy chromanyl palmitate.
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.

Moisturizing
What does the product description say?
This silky gel features a lightweight texture that nevertheless provides a deeply hydrating experience, leaving the skin feeling nourished and plumped from within.
Source: SpaceNK
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:
anhydroxylitol, 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, dimethiconol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: decapeptide-22, niacinamide, palmitoyl decapeptide-21, zinc palmitoyl nonapeptide-14
Helps attract water to the upper layer of the skin and repair the skin barrir function
