What the product description says

“Blue Therapy Night Cream”

From product name

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: cocos nucifera oil, copernicia cerifera wax.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, hydroxypalmitoyl sphinganine, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1

Anti-aging

Not advertised by the brand · Adenosine, Palmitoyl tetrapeptide-7 + 3 more

Strong evidence

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Product summary

"BIOTHERM - Blue Therapy Night Cream" is a well-rounded moisturizing product. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (glycerin, sodium hyaluronate, sodium lactate, butylene glycol and caprylyl glycol) 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 (ceramide np, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, passiflora edulis seed oil and persea gratissima oil) 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 (ceramide np 0.25% - 0.50%). 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 (palmitoyl tripeptide-1 0.25% - 0.50% and palmitoyl tetrapeptide-7 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.
Adenosine 0.20% - 0.40%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: titanium dioxide, salicylic acid, vitamin e, caprylic/capric triglyceride, stearic acid and apricot kernel oil
