“Ageing and Dehydrated Skin Helps smooth and tone ageing and wrinkled skin on both the face and body, and helps retain moisture. Key Features”
Source: Boots

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: helianthus annuus seed oil, glycine soja oil.

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).

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

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~1.8–2.7%

Glycine soja oilKey active· EmollientEffect: HighA good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.~0.5–1.15%
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~0.5–1.1%

“Ageing and Dehydrated Skin Helps smooth and tone ageing and wrinkled skin on both the face and body, and helps retain moisture. Key Features”
Source: Boots

This product contains retinyl palmitate. 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 palmitateKey activeEffect: 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~1.8–2.7%
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~0.4–0.95%
