What the product description says

“It protects skin from dry air, prevents roughness and cracking, and keeps skin moist and moisturized.”

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: glycerin, sodium hyaluronate.

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, glyceryl stearate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: paraffinum liquidum, urea

UreaHero· HumectantEffect: HighNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~1.3–2%

Paraffinum liquidumHero· Emollient, OcclusiveEffect: HighMineral oil. One of the most effective and well studied occlusive and emollient moisturizing ingredients. Helps reduce moisture loss in skin and repair skin barrier function~3.8–5.6%

SqualaneKey active· Emollient, OcclusiveEffect: HighAn 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.~0.45–1.05%

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~4.6–6.9%

UbiquinoneKey activeEffect: HighCoenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen~0.4–0.9%

Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~0.8–1.2%

Sorbitol· HumectantEffect: LowHelps attract water to the upper layer of the skin and improves the product texture~0.15–0.5%

Stearic acid· EmollientEffect: LowHelps oil and water mix together and works as an emollient~2.1–3.1%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.15–0.6%

Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~1.7–2.5%

PanthenolUnder-dosedEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.1–0.4%

Ascorbyl tetraisopalmitateEffect: Low, below effective doseA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.15–0.6%

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~0.1–0.5%

Anti-oxidation

Strong evidence

This product contains antioxidants (ubiquinone) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Anti-aging

Not advertised by the brand · Ubiquinone, Tocopherol + 2 more

Moderate evidence

This product contains ubiquinone. This ingredient help neutralize free radicals in skin. By doing so, they might be able to prevent early signs of aging (like fine lines and wrinkles), at least to some extent. These ingredients will not be able to "reverse" signs of aging.

UbiquinoneEffect: LowCoenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen~0.4–0.9%

It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.15–0.6%

Retinyl palmitateUnder-dosedEffect: MediumThree 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~0.05–0.25%

Product summary

Based on the ingredients included, "STH - KINUHADAKOMACHI Hand & Heel Cream Tube Type" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. STH - KINUHADAKOMACHI Hand & Heel Cream Tube Type ticks this box. Urea, glycerin, sodium hyaluronate, butylene glycol and propylene glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (paraffinum liquidum, squalane, glyceryl stearate, isopropyl palmitate and stearic acid) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

this moisturizer includes a form of Retinoids (vitamin A) - retinyl palmitate 0.05% - 0.25%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: vitamin e and ascorbyl tetraisopalmitate

Irritation risk

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
