What the product description says
“For shaving: Provides exceptional moisturization and soothing benefits when used as a pre-shave preparation or as a stand-alone shaving oil.”
Source: SmallFlower

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: butyrospermum parkii butter, dimethiconol.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~23–35%
DimethiconolKey active· Emollient, OcclusiveEffect: HighA silicone that makes products more spreadable and keeps skin smooth. Helps to add gloss to skin and may visually fill in fine lines/wrinkles for short time~5.2–7.8%
Hydrogenated ethylhexyl olivateKey active· EmollientEffect: MediumHelps soften the upper layer of the skin~4.4–6.6%
Jojoba estersKey active· EmollientEffect: HighAn emollient made of jojoba oil. Helps soften the skin and support its barrier function~3.8–5.7%

Argania spinosa kernel oilKey active· EmollientEffect: HighAn emollient that helps soften the upper layer of the skin. Might have some weak anti-oxidant properties~1.7–2.6%
Simmondsia chinensis seed oilKey active· Emollient, OcclusiveEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~1.3–1.9%
Olea europaea fruit oilKey active· EmollientEffect: MediumAn emollient that helps soften the skin but is not effective for restoring its barrier function. Might be helpful to calm down inflammation~1.3–2%

Moringa oleifera seed oil· EmollientEffect: LowA plant oil that helps soften the upper layer of the skin. Is unlikely to be helpful in restoring skin barrier function due to the low content of linoleic acid~0.35–0.85%

What the product description says
“Organic Moringa Seed Oil provides anti-aging and firming benefits, while a powerful combination of antioxidant-rich Argan Oil, Organic Marula Seed and Grape Seed oils helps reinforce skin?s natural defenses, soothe redness, and restore elasticity and suppleness.”

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.

Butyrospermum parkii butterEffect: LowA 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~0.5–1.2%
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~0.35–0.8%
Ascorbyl palmitateEffect: Low, below effective doseBeing a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.~0.15–0.55%
Retinyl palmitateUnder-dosedThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.1–0.45%
