What the product description says
“Feather Canyon helps improve the look of fine lines, while Echium and Hyaluronic Acid hydrate without overloading, leaving skin plump.”
Source: Content

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, lactobacillus ferment.

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: butyrospermum parkii butter, helianthus annuus seed oil.

Carthamus tinctorius seed oilKey active· EmollientEffect: HighAn emollient that helps soften the skin and might help calm down inflammation~2–2.5%
Lactobacillus fermentKey active· HumectantEffect: HighA fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative~2.4–2.9%
Myristyl myristateKey active· Emollient, OcclusiveEffect: HighAn emollient. Is not recommended for acne-prone skin as it can be comedogenic~1.1–1.3%

Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.15–0.3%
Argania spinosa kernel oilKey active· EmollientEffect: HighAn emollient that helps soften the upper layer of the skin. Might have some weak anti-oxidant properties~1.5–1.8%
Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~1.3–1.6%
Echium plantagineum seed oilKey activeEffect: HighA plant oil that because of its high content of alpha-linolenic acid help support skin barrier function and moisturize the skin~0.35–0.65%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.1–3.8%

Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~0.9–1.1%
Heptyl undecylenateKey active· Emollient, OcclusiveEffect: MediumHelps soften the upper layer of the skin, reduce water loss from the skin surface over time and create a nice product finish~4.5–5.5%
Glyceryl caprylate· EmollientEffect: LowAn emollient that can also help water and oil mix together, as well as prevent bacteria growth in products~0.3–0.5%
Glyceryl stearate citrate· EmollientEffect: LowHelps oil and water mix together while softening the upper layer of the skin~1.7–2.1%
Lactic acidUnder-dosedEffect: HighAn 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)~0.3–0.55%
TocopherolEffect: Low, below effective dosePure 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~0.2–0.35%

“Feather Canyon helps improve the look of fine lines, while Echium and Hyaluronic Acid hydrate without overloading, leaving skin plump.”
Source: Content

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
