“Deeply nourishing hydrator to visibly smooth wrinkles and boost vibrancy – this is so much more than just a moisturiser.”

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: anhydroxylitol, betaine.

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, helianthus annuus seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl decapeptide-21, salicyloyl phytosphingosine, zinc palmitoyl nonapeptide-14

Product summary

Based on the ingredients included, "Trinny London - Bounce Back" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Trinny London - Bounce Back ticks this box. Humectants in this product (salicyloyl phytosphingosine, anhydroxylitol, betaine, glycerin and sodium hyaluronate) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (dimethicone, helianthus annuus seed oil, simmondsia chinensis seed oil, squalane and cetearyl alcohol) 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

  • Another benefit is that this moisturizer contain ceramides (salicyloyl phytosphingosine 0.30% - 0.55%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
  • We like that this moisturizer contains peptides (zinc palmitoyl nonapeptide-14 0.25% - 0.45% and palmitoyl decapeptide-21 0.25% - 0.50%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: lactic acid and avena sativa kernel oil
