Product Summary
"111SKIN - Celestial Black Diamond Neck and Décolletage Serum" is effective for: Moisturizing
This product could be helpful for: Anti-aging, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Peptides (trifluoroacetyl tripeptide-2 0.10% - 0.20%, palmitoyl tripeptide-1 0.15% - 0.25% and palmitoyl tetrapeptide-7 0.15% - 0.30%). 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 theynare 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.
- Humectants (urea 0.25% - 0.50%, sodium pca 0.75% - 1.15%, sodium lactate 1.10% - 1.30%, inositol 0.25% - 0.45%, glycine 0.30% - 0.55%, glycerin 3.10% - 3.80%, fructose 0.30% - 0.55% and dextran 0.15% - 0.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Moisturizing
What does the product description say?
MOISTURE COMPLEX.
Source: 111skin
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, fructose.
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: isopropyl myristate, vitis vinifera seed oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, trifluoroacetyl tripeptide-2, urea
Naturally present in skin and helps to attract water to its upper layer
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
Naturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations
A great emollient that can also have anti-oxidant properties
Helps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product
Helps to attract water to the upper layer of the skin and can help restore the skin barrier function
An emollient that helps soften the skin. Could be comedogenic
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
Helps attract water to the most upper layer of the skin. Derived from sugar
Helps attract water to the upper layer of the skin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin
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)
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
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
Anti-aging
What does the product description say?
Visible signs of ageing are significantly diminished.

This product contains palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, trifluoroacetyl tripeptide-2. 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.

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 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
Anti-oxidation
This product contains antioxidants (ginkgo biloba leaf extract) 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 plant extract that might help neutralize free radicals and reduce inflammation in skin. It can be irritating
Plant extract. Might have some anti-oxidant properties. Can be irritating
A great emollient that can also have anti-oxidant properties
