What the product description says
“Tone and moisturise the neck with the DHC CoQ10 Neck Cream, a velvety, emollient-rich caring salve diligently advanced to hydrate and condition the skin.”
Source: Lookfantastic

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: sodium hyaluronate, soluble collagen.

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, caprylic/capric triglyceride.

Soluble collagenKey active· HumectantEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~0.15–0.25%

“Formulated with radical-fighting Coenzyme Q10 to replace the skin’s diminishing natural levels through maturity, this clarifying blend sufficiently encourages elasticity, consequently reducing the effect of sagging.”

This product contains serine. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

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~0.15–0.3%
Ascorbyl tetraisopalmitateUnder-dosedEffect: MediumA 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.
