Key actives
Product Summary
"RNW - DER. CONCENTRATE 4-TERPINEOL PLUS 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
- Ceramides (ceramide np 0.75% - 1.10%). 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.
- Actives derived from an extract of the Centella Asiatica plant (also known as Gotu Kola) - madecassoside 1.40% - 1.70% The Centella Asiatica Actives help strengthen and restore the skin barrier, decrease inflammation in skin and neutralize free radicals. They also can help to reduce scarring. The good news is that these actives work even in low concentrations.
- In addition, this product contains Allantoin (0.70% - 1.05%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
- Humectants (hydrolyzed hyaluronic acid 0.10% - 0.15%, fructooligosaccharides 0.10% - 0.20%, algae extract 0.65% - 0.95% and glycerin 2.50% - 3.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-oxidation
This product contains antioxidants (madecassoside) 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 - centella asiatica extract, ficus carica fruit extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
An antioxidant that is typically derived from plant Centella Asiatica. It can help neutralize free radicals in skin and support skin barrier function. It could, however, itself be irritating. It is often unstable in formulations
A plant extract that can help neutralize free radicals. The concentrations typically used in cosmetics are too small to have an effect
A plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.
A plant extract that can help neutralize free radicals in skin. It contains a compound salicin that can theoretically be converted into salicylic acid that, in turn, helps reduce inflammation in skin, but the evidence of effectiveness in skin is lacking and the extract is usually not used in a concentration that would enable an exfoliating effect
Helps attract water to the upper layer of the skin, calm down inflammation and irritation, restore the barrier function and support wound healing. It can be helpful in reducing fine lines and wrinkles
Green tea leaf water. Might have some minimal anti-oxidant effect
A plant extract that might contain a compound baicalin that could be helpful in neutralizing free radicals and reducing inflammation in skin. The baicalin concentration in skincare products is often too low for an effective action. Can be used for its fragrant properties
A plant extract. Can have an anti-oxidant effect, but can also contain irritants
A plant extract that has some anti-oxidant activity, but solid research is lacking. Can help attract water to the upper layer of the skin
A plant extract that is mostly used as a fragrance. Might have some anti-oxidant effect

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, fructooligosaccharides.
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: algae extract.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, madecassoside
Plant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet
