Key actives
Product Summary
"Bonjour - Biome Shield Cera Toner" is effective for: Anti-aging and Moisturizing
This product could be helpful for: Evens skin tone, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Ceramides (ceramide np 0.50% - 1.20%, ceramide eop 0.55% - 1.30%, ceramide ns 0.85% - 1.30%, ceramide ap 1.00% - 1.60% and ceramide as 1.20% - 1.80%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
- Adenosine 0.15% - 0.70%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
- Humectants (saccharide isomerate 0.45% - 1.00%, betaine 0.45% - 1.05%, glycerin 2.70% - 4.10% and pitera 22.00% - 33.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: galactomyces ferment filtrate.
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.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
A yeast ferment filtrate (also known as Pitera - a trademarked name for the filtrate reserved by the SK-II brand). It helps attract water to the upper layer of the skin, can help neutralize antioxidants and can be helpful in evening out the skin tone. It might be somewhat helpful in preventing premature skin aging but solid evidence is lacking. A small manufacturer study also shows that, when used in high concentrations, it can help reduce sebum production and help against blocked pores
Seaweed extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but good research is lacking at the moment
Anti-oxidation
This product contains antioxidants (galactomyces ferment filtrate) 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 - bifida ferment lysate also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Moisturizing
What does the product description say?
This is a rich moisturizing toner that replenishes moisture in dehydrated skin and strengthens the skin barrier.
Source: Yesstyle
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:
betaine, galactomyces ferment filtrate.
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: cholesterol, caprylyl glycol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ap, ceramide as, ceramide eop, ceramide np, ceramide ns
Helps attract water to the upper layer of the skin
A type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin
