What the product description says
“Aqualia Thermal Serum provides 48-hr dynamic hydration to recharge dry and dehydrated skin and smooths fine lines & wrinkles.”
Source: Vichy

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: biosaccharide gum-1, glycerin.

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: dimethicone, dimethiconol.

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%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~3.7–5.5%
Peg/ppg/polybutylene glycol-8/5/3 glycerinKey active· HumectantEffect: MediumHelps create a nice product texture and attract water to the upper layer of the skin~2.6–3.9%
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~1.7–2.5%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.3–1.9%
Chondrus crispusKey activeEffect: HighRed algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~0.9–1.3%
Biosaccharide gum-1Key active· HumectantEffect: HighHelps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin~0.1–0.35%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.3–0.7%

Product summary

"Vichy - Aqualia Thermal Rehydrating Serum" could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • Salicylic acid (0.40% - 0.90%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.
  • Humectants (sodium pca 1.10% - 1.60%, sodium hyaluronate 0.85% - 1.30% and glycerin 4.20% - 6.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails from 19.50£ up to 29.00£ in the United Kingdom, for 44.95CA$ in Canada and from 25.00$ up to 36.00$ in the United States.
