Product summary

"Nécessaire - The Neck Serum - With 5 Peptides | 9% Peptide Blend" is effective for: Moisturizing and Anti-aging

This product could be helpful for: Evens skin tone, but its actives are not the most effective or are not well-studied.

Ingredient callouts

Peptides (palmitoyl tripeptide-5 0.20% - 0.75%, palmitoyl tripeptide-1 0.35% - 0.80%, palmitoyl tetrapeptide-7 0.40% - 0.90%, palmitoyl hexapeptide-12 0.40% - 0.90% and acetyl hexapeptide-8 0.45% - 1.05%). 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. They 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.
Humectants (acetyl hexapeptide-8 0.45% - 1.05% and glycerin 4.40% - 6.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What can the product work for?

Anti-aging

What does the product description say?

The neck area feels firm and looks lifted.

Source: Sephora

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains palmitoyl hexapeptide-12.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, 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.

Moisturizing

What does the product description say?

, Niacinamide (Vitamin B3) Helps to support skin's natural barrier.

Source: Sephora

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: glycerin, caprylyl glycol.

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: squalane, coco-caprylate/caprate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, palmitoyl hexapeptide-12, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5

palmitoyl tripeptide-1 0.35% - 0.8%

Irritation risk:

Concentration: Effectiveness: HIGH

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

squalane 2% - 3.1%

Irritation risk:

Concentration: Effectiveness: HIGH

An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.

palmitoyl tripeptide-5 0.2% - 0.75%

Irritation risk:

Concentration: Effectiveness: HIGH

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

Evens skin tone

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

chrysin 0.1% - 0.45%

Irritation risk:

Concentration: Effectiveness: MEDIUM

Might be helpful in reducing fine lines and wrinkles, as well as lightening the skin, but solid evidence is missing. Could somewhat help in reducing the darkness of the under-eye area. Helps to neutralise free radicals in skin

n-hydroxysuccinimide 0.1% - 0.45%

Irritation risk:

Concentration: Effectiveness: LOW

Is claimed to be able to brighten skin tone by removing some blood-related pigmented compounds in skin (hemoglobin and related elements) but solid research is missing. Can be irritating

niacinamide 0.6% - 1.4%

Irritation risk:

Concentration: Insufficient!

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

Anti-oxidation

This product contains antioxidants (chrysin) 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.

chrysin 0.1% - 0.45%

Irritation risk:

Concentration: Effectiveness: MEDIUM

tocopherol 0.2% - 0.8%

Irritation risk:

Concentration: Insufficient!

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

rosa damascena flower water 1.2% - 1.8%

Irritation risk:

Concentration: Insufficient!

Used to add a nice rose smell to the product. Might help attract water to the upper layer of the skin and have some anti-oxidant effect. Can be irritating
